I. Statement of Policy & Intent
to Comply with Applicable Regulations
Compliance with Applicable Regulations:
It is the policy of Columbia University to comply with the applicable City,
State, and Federal regulations pertaining to asbestos containing material (ACM).
In order to achieve this goal the University has developed a comprehensive
in-house protocol to address the identification, in-place management, and abatement
of ACM.
The University supports stringent compliance with promulgated regulations
in conjunction with cost minimization.
Departments and other administrative units of the University are required
to provide a copy of this document to employees involved with the planning
and/or scheduling of construction, maintenance, and other projects where the
potential to impact ACM exists. In addition, such Columbia personnel are responsible
for Contractor and sub-Contractor compliance with this policy.
To summarize, ACM (friable and non-friable)
shall only be removed or otherwise impacted by a licensed asbestos abatement
Contractor utilizing licensed workers. ACM or other asbestos contaminated
debris/waste shall be properly labelled and transported off-site by a licensed
waste hauler to a registered landfill, where proper Manifesting procedures
("cradle to grave" documentation) shall
be utilized.
The Office of Environmental Health and Radiation Safety shall provide technical
assistance in achieving the goals of this policy.
Review of Applicable Regulations:
In the City of New York there are multiple regulatory agencies which have
jurisdiction over asbestos containing materials (ACM) in buildings including
the New York State Deptartment of Labor (NYS DOL), the New York City
Department of Environmental Protection, (NYC DEP), The New York City Department
of Health (NYC DOH), the federal Occupational Safety and Health Administration
(OSHA), and the Federal Environmental Protection Agency (EPA). Each agency
has promulgated regulations which address the various aspects of maintenance
and handling of ACM in order to protect building occupants from asbestos exposure
and to protect the ambient air.
NYS DOL regulations
The New York State Department of Labor has adopted Industrial Code Rule
56 (ICR-56) to address the proper identification, handling, removal, and disposal
of ACM in public buildings (superseded by NYC DEP regulations in NYC only).
NYC DEP regulations
In a similar manner the New York City Department of Environmental Protection
adopted Local Law 76 which was later revised as Title 15 Chapter 1. These regulations
also address the proper identification, handling, abatement, and disposal of
ACM in public buildings and in NYC only (i.e.. Nevis and LaMont campuses must
follow NYS ICR-56), supersede NYS DOL ICR-56 regulations as per order of the
NYS DOL. In NYC (i.e.. Main and Uptown campuses), State Inspectors may only
issue violations for licensing deficiencies (not work practice related issues);
City Inspectors have jurisdiction over all engineering control/work practice
relate issues.
NYS DOH regulations
NYC Department of Health Code Rule (sections 3.09-3.11) require the abatement
of damaged ACM which may pose a health and/or nuisance hazard to building occupants.
Federal OSHA regulations
Federal Occupational Safety and Health Administration regulation address
both in-house and Contractor worker protection an notification. The 8/10/94 "OSHA
Final Rule on Occupational Exposure to Asbestos" amended OSHA standards 29CFR1910.1001/1101
and introduced the concept of "negative exposure assessments" and mandates
labelling of accessible ACM.
Federal EPA regulations
The federal Environmental Protection Agency has promulgate regulations
under the Asbestos Hazard Emergency Response Act (AHERA), National Emissions
Standards for Hazardous Air Pollutant regulations (NESHAPS), and the Toxic
Substances Control Act (TSCA) The AHERA regulations address asbestos issues
in schools (grades K-12). EPA NESHAPS regulations prohibit "visible emissions" of
asbestos and specify off-site disposal procedures to be utilized.
** The above listed agencies may impose fines of $1000 to $100,000 per
day and prosecute negligent Building Owners for non-compliance with the
applicable regulations.
The above listed regulations are available
on CD ROM for review a the EH&S office.Go to

II. Asbestos Policy Responsibilities
a. Role of EH&S office:
The role of Environmental Health and Safety is to assist
the various departments and other administrative units in complying with the
applicable regulations and this asbestos policy. In order to insure compliance
with this policy the EH&S office shall conduct routine inspections/audits
of abatement and other construction projects. When outside environmental Consultants
are retained for large capital projects, EH&S shall be responsible for
compliance with this policy as well as technical review. EH&S , in consultation
with the University Office of the General Counsel, shall be responsible for
regulatory agency correspondence as it relates to asbestos projects.
The EH&S office shall generate an "approved asbestos Contractor's list" which
shall indicate those vendors (Contractors and Consultants) approved to work
on asbestos projects at Columbia University. Only those firms included on the
approved list may be participate in asbestos abatement projects at Columbia.
b. Role of the Asbestos Coordinator:
Within the EH&S office the position of Asbestos Coordinator has been
created to provide the technical assistance described above. The Asbestos Coordinator
is under the direct supervision and advisement of the Director of EH&S .
c. Notification of the EH&S Department:
All projects and other events which may potentially involve asbestos shall
be reported directly to the EH&S office immediately by phone or utilizing
the appropriate form. Examples of such situations are the following:
-
Maintenance projects (plumbing & HVAC)
-
General construction & renovation
-
Emergency pipe breaks and floods
-
Electrical work above suspended ceilings
-
Any work in the steam tunnels, Powerhouse, or other
mechanical equipment areas

When there is any potential for an asbestos
containing material be impacted the EH&S office shall be notified
immediately (212)854-8749. All Contractors and Consultants are required to
notify the EH&S office directly of all
pending work no less than 24 hours prior to commencement of work. Failure
to satisfy the notification or any other requirement of this policy may jeopardize
the vendor's position on the approved list.
In order to legally and properly classify a Material as ACM or non-ACM bulk
sampling and laboratory analysis (by a NYS ELAP certified laboratory) must
be conducted. Friable samples such a pipe insulation shall be analyzed using
the Polarized Light Microscopy (PLM) Method. Roofing, transite, floor tile
and other non- friable samples are analyzed using the Transmission Electron
Microscopy (TEM) Method.
d. Submittal of "Project Notification and Inspection Request" form:
The EH&S Department shall be notified of asbestos related events using
the Project Notification and Inspection Request form. The Project Notification and Inspection Request form will be forwarded to the Asbestos Coordinator for project scheduling.
If any questions arise regarding these notification procedures, refer to "Guidelines for Completing the Project Notification and Inspection Request Form" or EH&S shall be contacted at (212)854-8749.
It should be emphasized that outside Consultants and Contractors are not
exempt from satisfying the notification and other requirements of this policy.
The Facilities Management Project Managers, Directors, Supervisors, Area Managers,
and other involved personnel are responsible for informing the Contractors
and Consultants which they retain of the terms and conditions of this policy.
Failure to inform outside Contractors and Consultants of this policy shall
be considered non- compliance with this policy.
III. Review of Asbestos Terminology
In order to provide as much clarity as possible, listed below are a few key
definitions:
-
Abatement
An approved method for handling
asbestos containing materials (i.e. removal, encapsulation, enclosure).
-
Air Monitoring

where the material is present with a hard permanent barrier. The insulated
vertical heating risers located behind exterior/perimeter walls and above
hard plaster Ceilings may be considered to be enclosed if the walls are not
demolished or otherwise penetrated.
-
Asbestos Containing Material

to contain 1% or greater asbestos.
-
Asbestos Removal Project
The physical removal of asbestos containing materials by a licensed
Contractor employing trained and licensed personnel and following the
applicable regulations.
-

-
PLM
Polarized light microscopy is the standard approved method for analysis
of "asbestos in bulk" samples.
-
TEM
Transmission electron microscopy is the "state of the art" (lowest achievable
detection limit) method for analysis of
"asbestos in air and bulk samples".
-
VAT

-
NYC DEP ACP-7 "Asbestos Project"
Notification Form.
An ACP-7 must be completed and submitted to the NYC DEP Asbestos
Control Department at least seven working days in advance of asbestos
abatement projects involving 25 linear/10 square feet or greater of friable
ACM per level (in addition, for large projects, the project must be filed
with the NYS DOL and EPA NESHAPS division at least 10 calendar days from
the start date of the abatement project).
-
NYC DEP ACP-5 "Not an Asbestos Project"
Notification Form
An ACP-5 form has multiple applications; non- friable transite and
floor tile as well as "minor" quantities of friable ACM (less than 25
linear/10 square feet) of friable ACM may be removed under an ACP-5;
an ACP-5 is also used to provide documentation that, while ACM may be
present, it will not be impacted during a renovation project. An ACP-5
form must be signed and stamped by a licensed NYC Asbestos Investigator.
IV. Notification
("Hazard Awareness") for In-House Personnel
a. Definition of asbestos exposure
According to OSHA regulations and in-house bargaining unit contractual
agreements, all employees who have been exposed to asbestos shall be notified
in writing. It should be emphasized that the term
"exposure", by OSHA definition, denotes encountering an elevated airborne concentration
(above the 0.01 fibers/cc permissible exposure limit) of a regulated substance
such that inhalation is possible. The presence of the substance in the building
does not necessarily constitute an exposure hazard. In the case of asbestos,
under normal circumstances, only damaged ACM becomes airborne and poses an
exposure hazard. According to OSHA protocol personal air sampling must be conducted
in order to determine whether and actual exposure hazard exists. While the
University is committed to protecting all employees from an airborne exposure
hazard, this does not guarantee that all areas shall be deemed "asbestos free."
b. Emergency notification
Since uncontrolled disturbances of ACM may potentially result in the exposure
of in-house personnel and other workers to airborne asbestos implementation
of this policy to critical. In the event such an uncontrolled release occurs, "emergency" asbestos
air monitoring and off-site analysis shall be conducted immediately by EH&S or an authorized representative. The results of such emergency testing shall
be reported in writing to those persons affected and their authorized union
representatives, if applicable.
c. Routine notification:
For scheduled maintenance and construction projects involving asbestos
abatement work all building occupants potentially affected shall be notified
in writing seven calendar days prior to the onset of abatement work. For large
projects only, the results for all air sampling and analysis events shall be
posted on a daily basis in the building and shall be on-file at the EH&S office available for review. Copies of final clearance air sample results shall
be forwarded to authorized union representatives as required.
d. Labelling of accessible ACM:
Pursuant to the 8/10/94 "OSHA Final Rule on Occupational Exposure to Asbestos" all
accessible ACM (i.e.. not enclosed above hard plaster ceilings/behind walls)
shall be labelled with "asbestos hazard"
labels such that the material may be avoided by Plumbers, Electricians, and
other in-house and Contractor personnel.
Under the OSHA final rule, any material must be considered as ACM unless specifically
tested.Go to Top
V. General
Asbestos Related Considerations for Planning Construction Projects
Since many campus buildings were constructed
prior to 1975, "asbestos containing"
material is likely to be present and may be impacted during HVAC, structural,
and other renovation projects. In order to obtain plumbing, electrical, demolition
and other Building Department permits (requires ACP-5 submittal) and comply
with this policy, an asbestos investigation is required.
In order to avoid delaying general construction, it is highly recommended
that asbestos related phases of projects (asbestos abatement is usually always
included in Phase I demolition work) be scheduled as soon as possible once
the project is budgeted. If extensive interior demolition work is scheduled,
enclosed/concealed ACM running behind walls and above ceilings may be exposed
and should be considered in defining the scope of work.
The Asbestos Coordinator shall review the available project drawings in order
to determine whether ACM may potentially be impacted.
a. Review of asbestos survey & abatement
work conducted previously
Over the past ten years asbestos sampling and analysis work has been conducted
for various construction and maintenance projects. The documentation for such
previous survey work is available for review at the EH&S office. Upon
request the Asbestos Coordinator shall search the "Asbestos Building File" for
relevant information. Any information retrieved shall be reviewed for integrity
and forwarded to the appropriate Facilities Project Manager and/or Department
Manager. In some instances additional representative bulk sampling and analysis
is required to verify the previous survey work.
b. Asbestos building surveys/hazard assessments:
For major construction and other projects where no previous sampling and
analysis data is available an asbestos survey/hazard assessment is required.
Such a survey involves collection of representative bulk samples such that
various materials may be classified as ACM or non-ACM. Wherever possible the
locations of ACM shall be marked on a project drawing.
Protocol for asbestos building surveys
In order to accurately assess the building and follow EPA AHERA protocol
for asbestos building surveys the following sample collection frequency shall
be utilized for asbestos building surveys:
3 samples per homogeneous area/material for surfaces <1000
sq.ft.
5 samples per homogeneous area/material for surfaces
1000-5000 sq.ft.
7 samples per homogeneous area/material for surfaces >5000
sq.ft.
For thermal system insulation (TSI) the general procedure to satisfy the
above listed criteria is to collect three samples of each type of homogeneous
material per mechanical room/riser area. The procedure for floor tile is self
explanatory (3 samples per 1000 sq.ft. tile + mastic), however confirmatory
TEM/NOB (non organically bound) analysis is required. The material type which
requires the greatest number of samples to accurately characterize due to its
inherent inhomogeneity and large surface area is wall and ceiling plaster.
For example, plaster found on exterior and structural walls is commonly not
of the same composition as interior partition wall plaster. In order to provide
results which reflect this lack of uniformity a relative large number of samples
are required to accurately characterize this material.
Selection of laboratory methodology
The standard methodology for analysis of "asbestos in friable bulk samples" is
the PLM method. For analysis of non-friable floor tile and roofing asphalt
samples the more expensive NOB/TEM method is required by the applicable regulations
and shall be utilized. For analysis of wall/ceiling plaster samples the TEM
analysis method shall be utilized for plaster samples which are shown by the
PLM method to contain 0-5% asbestos content in order to achieve reasonable
accuracy.
Quality control samples
At the discretion of the EH&S Asbestos Coordinator and/or Director
additional "blind duplicate" quality control samples may be collected and submitted
to a second approved independent laboratory for analysis.
Asbestos air sampling & analysis/exposure
monitoring
In addition to the bulk sampling and analysis mentioned above baseline
air sampling may be specified to evaluate the hazard potential of asbestos
exposure in a particular area.
Estimation of quantities and abatement costs
The estimated quantity of ACM identified and associated abatement costs
shall be listed in the building survey report. Abatement Contractor estimates
of quantities without verification shall not be considered acceptable for filing
or budgeting purposes.
c.
"Negative exposure assessments"/ACP-5's:
If, after the asbestos building file search and survey work mentioned above,
it is determined that no asbestos may potentially be impacted, a "negative
exposure assessment" report (as defined by the most recent OSHA regulations)
shall be issued. In addition to the negative exposure assessment, an ACP-5
may be completed and filed with the Building Department as required. It should
be emphasized that completion of either a "negative exposure assessment" or
ACP-5 is contingent upon no disturbance of ACM for a particular project; it
does not require that a building or area be "asbestos free".
d. Management of outside Contractors & sub-Contractors:
It is the responsibility of the Facilities Project Manager and/or Department
Manager to insure that all outside Contractors and sub-Contractors comply with
this policy and the applicable regulations. As the legal "Building Owner" Columbia
University may be liable for all environmentally related incidences regardless
of Contractor negligence. A statement regarding compliance with this asbestos
policy should be incorporated into contracts with outside firms. Furthermore,
the contracts should indicate such that non-compliance may result in withholding
payments.
It is the responsibility of the University to notify outside Contractors
of the presence of ACM in the areas which they work.Go to Top
VI. Procedures
for Managing Asbestos Abatement Projects
a. Preparation of asbestos project specifications/selection of abatement
alternative
To summarize, the most common EPA approved asbestos abatement alternatives
may be described as the following:
Abatement
Alternative |
Advantages |
Disadvantages |
1. in-place management/no
action (in conjuction with O&M programs |
low cost |
not permanent remedy ACM must be in good
condition |
2. complete of partial removal |
permanent remedy |
highest initial cost |
3. encapsulation/wrap & repair |
moderate cost |
not permanent remedy ACM must be in fair
condition |
4. enclosure |
ACM may be in poor condition |
not permanent remedy high intial cost |
It is the policy of the University to select the most cost effective abatement
alternative. However, the need for upcoming renovation work (i.e. replacement
of the HVAC system) may dictate removal as the most feasible abatement option
since it does offer a permanent solution. In many circumstances it is recommended
that the Project Manager solicit price quotations for several alternatives
such that they may be compared.
For projects in excess of $10,000 asbestos
abatement bidding specifications shall be prepared and presented at a pre-bid
meeting which the Faculty and other building occupants are invited to attend.
For smaller asbestos projects a brief "work plan" shall be prepared by the EH&S Asbestos Coordinator which outlines the procedures to be utilized.
In addition to asbestos abatement procedures the requirements for 3rd party
air monitoring and analysis (including sampling frequency and analytical methodology)
shall be outlined in the project specifications. A copy of the project specifications
may be forwarded to the appropriate union representatives upon request.
b. Selection of approved licensed Contractor and Project Monitor
If a proposal for asbestos abatement work is approved, a licensed asbestos
abatement Contractor and 3rd Party Asbestos Air Monitoring Firm must be retained.
Both parties shall be selected from the "Columbia Approved Asbestos Contractor
List" on-file at the EH&S and Facilities Management offices. Standard
Facilities Management bidding/contracting rules shall be applied to asbestos
abatement projects. Sufficient time should be allotted for the contracting
process since the cost of "rush" (i.e. less than 10 days notice) is substantially
higher than standard projects.
c. Regulatory agency filing requirements/waiting periods
The NYC and NYS asbestos regulations clearly state that it is the abatement
Contractor's responsibility to notify the appropriate regulatory agency of
the impending abatement project. However, failure to file asbestos abatement
projects subjects both the Contractor and the Building Owner to fines.
The filing requirements in NYC are summarized according to the following:
Regulatory
Agency |
Size of Project |
Filing Requested |
Waiting Period |
NYC DEP |
minor (<10 sq./25 ln.ft.)
small (10-160 sq./25-260 ln.ft.)
large (<160 sq./260 ln.ft.) |
n/a

n/a
10 days |
It should be mentioned that applicable
and special variances to deviate from the regulations normally require three
to six weeks to obtain. All variance applications shall be pre-approved by EH&S prior to submittal to the DEP.
Copies of asbestos project filings shall
be posted in the buildings, on-file at the EH&S office, and be submitted
to affected union authorized representatives.
The NYC DEP ACP-7 form must be signed and dated by the Contractor, the Building
Owner Authorized Representative, and the Project Monitor.
d. Additional air samplinq/exposure monitoring required to satisfy union
contract requirements:
In addition to the asbestos air monitoring requirements specified in the
applicable regulations (only require air monitoring when >10 sq./25 ln.ft.
of ACM is disturbed) the University bargaining unit contract may require asbestos
air monitoring when any amount of ACM is disturbed. Such additional air monitoring
shall be coordinated by the EH&S office.
e. Responsibilities of Facilities Project/Construction Managers during
abatement projects (see attached checklist):
In order to simplify the construction management aspects of asbestos abatement
projects as much as possible an Asbestos Project Management Checklist has been
prepared. The items included on the list have been shown to be "critical pathways" to
achieving in successful (i.e. no DEP or other violations, content building
occupants) projects in a cost effective and timely manner.
* Asbestos Project Management Checklist
In order to efficiently manage asbestos abatement projects Facilities
Project and Construction Managers should confirm that the following Issues
are addressed:
Bidding issues
(1) Has the abatement Contractor's scope of work been clearly defined?;
the project specifications/work plan should provide clear instructions on how
to conduct the project (including how the Contractor should file, what engineering
controls should be used, etc.)
(2) Have the quantities of ACM, which the cost of the project is primarily
based upon, been verified by someone other than the Contractor (i.e. Project
Engineer, Asbestos Coordinator)?
(3) Is re-insulation of the removal substrate required by NYC Fire/Building
Code?; if so, has re-insulation been included in the project bidding specifications
Pre-project administrative issues
The following should be addressed at least 10 days prior to the start of
abatement work:
(4) Selection of licensed asbestos
abatement Contractor found on EH&S "approved Contractor list"
(5) Selection of licensed 3rd party
asbestos air monitoring firm found on EH&S "approved Contractor list" [asbestos
air monitoring is typically 15-20% of the total contract value]
(6) Has the project been filed with the NYC DEP, NYS DOL, and EPA
as required?; if required, have variance applications been prepared and submitted?
(7) Have copies of the filings
been forwarded to the EH&S office,
the appropriate union representatives, and posted in the building?
(8) Have the appropriate Faculty been notified of the abatement project?
(9) A definite start date for abatement work must be selected (may
only be amended one time without monetary penalty from the NYC DEP)
Logistical
& scheduling issues
The following items should be addressed at least 24 hours to one week prior
to the onset of abatement work:
(10) Has a list of emergency phone/beeper
numbers been prepared &
distributed?; the following individuals should be included:
- Asbestos Coordinator
- Facilities Project/Construction Manager
- Facilities Area Manager
- Contractor Supervisor
- Air Monitoring Technician
(11) Has the Contractor provided
a written work schedule; has it been distributed to EH&S , the Faculty
involved, the Area Manager, etc.?Go to Top
(12) Does the Contractor have access to the space? Have arrangements
been made with Security?
(13) The University is normally responsible for providing a source
of water and electricity; the Contractor must identify the source and provide
suitable hook-ups/panels; have such arrangements been made?
(14) Is there a service elevator available for use by the Contractor
for equipment mobilization and bag-out?
(15) Is there space available for the Contractor to store equipment?
(16) For full containment abatement projects utility lines running
through the work area must be de-activated including electrical, steam heat,
and fire alarms; have work orders been completed to accomplish this? [failure
to de-activate such lines may result in a DEP violation]
Construction phase issues
(17) Are daily air monitoring results being posted in the building, faxed
to union representatives, and the EH&S Department within 24 hours of sample
collection?
Failure to post results may result in a DEP violation and is a violation
of the in-house union contract agreements
(18) Are asbestos hazard signs posted in appropriate locations?
(19) Is the asbestos Contractor posing a nuisance hazard to building
occupants by generating excessive levels of noise, dust, chemical hazards,
etc.?
(20) The Project/Air Monitor must conduct a final visual inspection
and clearance air sampling prior to dismantling of the containment; such events
should be documented
Project closeout issues prior to payment
of Contractor & Consultant
(21) Has the landfill copy of the waste manifest been returned to the EH&S office?
(22) Has the Project Monitor's
final report been submitted to the EH&S office?
(23) Has the work area sustained
damages (eg. water damaged carpets, ceiling tiles) which the Contractor
should be backcharged for?
VII. Overview
of Standard Removal Procedures
Depending on the size, scope, and location of the project the most feasible
removal method varies. For large scale projects a Project Designer should be
consulted to select the most cost effective option. For smaller projects the
following general procedures should be utilized:
a. Full containment removal (for homogeneous work areas)
The full containment removal work shall be conducted according to following
general sequence of events:
-
Restrict area and post asbestos hazard signs
-
Construct
"attached" worker decon
-
Seal off all outside openings (isolation/critical
barriers)
-
Pre-clean work area
-
Cover walls, floor, ceiling, and immovable objects
with poly sheeting
-
Conduct gross removal/lst phase cleaning
-
Conduct 2nd phase cleaning after required waiting
period
-
Conduct 3rd phase cleaning after required waiting
period
-
Bag-out asbestos waste
-
Conduct final inspection (Project Monitor)
-
Conduct final clearance air sampling (Project Monitor)
-
Encapsulate all surfaces in containment
-
Dismantle containment
to Top
b. Use of glovebag with tent procedure
(for "spot removal of pipe insul.)
For removal of pipe insulation at multiple locations (less than 1000 ln.ft.
per level) the glovebag with tent method of abatement shall be utilized.
Glovebag with tent removal projects shall be conducted according to the following
general sequence of events:
- Restrict area and post asbestos hazard signs
- Construct "remote" worker decon
- Seal off all outside openings (isolation/critical barriers)
- Construct tent/enclosure (poly walls, floor, ceiling)
- Pre-clean work area
- Hang and seal glovebags
- Inspect & smoketest glovebags (Project Monitor)
- Conduct removal of ACM inside glovebag
- Detach glovebag and bag-out as asbestos waste
- Bag-out asbestos waste
- Conduct final inspection (Project Monitor)
- Encapsulate pipes
- Conduct final clearance air sampling
- Dismantle tent
c. Removal of
"asbestos containing" floor tile (VAT)
In NYC non-friable VAT may normally be removed under an ACP-5 according
to the following general sequence of events:
- Restrict area and post asbestos hazard signs
- Construct worker decon
- Seal off all Outside openings (isolation/critical barriers)
- Construct tent/enclosure (poly walls, floor, ceiling)
- Pre-clean work area
- Conduct removal of VAT inside tent casing (using manual methods)
- Bag-out asbestos waste
- Conduct final inspection (Protect Monitor)
- Encapsulate floor
- Conduct final clearance air sampling
- Dismantle tent
If the project cannot be conducted under an ACP-5 (i.e. quantity exceeds 10,000
sq.ft.) the full containment method if abatement must be utilized as described
above.
VIII. In-Place
Management of ACM/O&M Programs
If, upon visual inspection, the ACM is
found to be intact (i.e. outer covering not broken, good adherence to substrate)
and for non-friable materials such as floor tiles in-place management is
a feasible abatement option since the material is not likely to pose an airborne
asbestos hazard. ACM which has sustained minor damage and undergoes wrap & repair shall be included in the O&M
program. For damaged ACM in-place management is not an acceptable abatement
option.
To utilize in-place management an ongoing
O&M program including the following
general elements must be instituted:
- Periodic (i.e. every 6 months) re-inspection of ACM
- Notify building occupants of re-inspections
- Written operations & maintenance program
- Labelling of all routine maintenance areas
- Recordkeeping of all O&M activities
- Air sampling & analysis to evaluate exposure
hazard (as required)
IX. Asbestos Emergency Response
Plan
In the event of an unexpected event such as a pipe break, building collapse,
or flood where ACM may potentially be impacted and released to the ambient
air the Asbestos Coordinator shall be contacted by pager and proceed to the
site immediately.
Fires and medical emergencies take precedence over asbestos exposure and shall
be addressed by the appropriate emergency personnel first. Fire and other emergency
rescue personnel shall not be prohibited from entering an area, however, they
will be advised on proper decontamination procedures. After such issues are
resolved the Asbestos Coordinator shall evaluate whether a potential asbestos
hazard exists. If such a hazard does exist the area shall be closed to public
access pending emergency air sampling, off-site analysis, and possible emergency
abatement action.
In the event an asbestos waste bag ruptures in route from the asbestos work
area to the hauling truck the abatement Contractor shall be liable for clean-up
including immediate containment of the spill and decontamination of all affected
surfaces. The area around the spill shall be immediately cordoned off under
the direction of the Asbestos Coordinator. Emergency air sampling shall then
be arranged by the Asbestos Coordinator to determine if an airborne exposure
hazard exists.
An Emergency contact list with names, beeper
#'s, and phone #'s is available at the EH&S office.
X.
Asbestos Emergency Procedures
The following are procedures for emergency response action in the case of
an asbestos fiber release on campus, either during the course of abatement
or during normal, everyday activities.
-
Upon loss of negative
pressure or electric power to the negative pressure exhaust during
abatement activities.
-
Upon discovery
of damage and defects in the decontamination enclosure system/or plastic
barriers during an abatement project.
-
For barrier disturbance,
loss of engineering controls for tent/glovebag procedures during abatement.
-
ACM debris found during the course
of normal, daily activities (non-abatement)
A. Upon loss of negative pressure
or electric power to the negative pressure exhaust during abatement activities: Abatement
shall stop immediately and shall not resume until power is restored and
negative pressure ventilation equipment is operating again. When
power failure or loss of negative pressure equipment lasts or is expected
to last longer than one-half hour:
-
The make-up air inlets shall be sealed airtight, and
-
The decontamination systems shall be sealed airtight after the evacuation
of workers and/or authorized visitors from the work area, and
-
All adjacent areas shall be monitored for asbestos fiber concentration
upon discovery of, and subsequently throughout, the power failure, and
-
The Asbestos Coordinator or representative shall be notified of the power
outage, and
-
Areas outside the barriers shall be monitored for asbestos contamination
by TEM air sampling, at the discretion of the Asbestos Coordinator or representative.

B. Upon discovery of damage and defects in the decontamination enclosure
system/or plastic barriers during an abatement project:
-
At any time during the abatement activity, if visible emissions are observed,
or elevated asbestos fiber counts outside the work area are measured, or
if damage occurs to barriers, abatement shall stop.
-
The source of the contamination shall be located, the integrity of the
barriers shall be restored, and
-
Visible residue shall be cleaned up using appropriate HEPA vacuuming and
wet cleaning procedures immediately, and
-
The Asbestos Coordinator or representative shall be notified of the situation,
and
-
Areas outside the barriers shall be monitored for asbestos contamination
by TEM air sampling, at the discretion of the Asbestos Coordinator or representative.
C. For barrier disturbance, loss of engineering controls for tent/glovebag
procedures during an abatement:
-
The enclosed surfaces shall be wet cleaned
using rags, mops or sponges, and
-
Be permitted sufficient time to dry, prior to HEPA vacuuming all substrates,
and
-
Be lightly encapsulated to lockdown residual asbestos, and
-
The Asbestos Coordinator or representative shall be notified of the situation,
and
-
Areas outside the tent shall be monitored for asbestos contamination by
TEM air sampling, at the discretion of the Asbestos Coordinator or representative.
D. ACM debris found during the course of normal, daily activities (non-abatement):
-
Isolation
barriers and negative pressure exhaust will be constructed as per the
Asbestos Coordinator or representative, and
-
The area to be cleaned by HEPA vacuuming and wet methods will be determined,
by the Asbestos Coordinator or representative, and
-
TEM air sampling shall be used to determine the initial exposure count
as per the Asbestos Coordinator, and
-
PCM air sampling shall be sufficient during clean up activity, but
-
The area will be closed until clearance by TEM air sampling, as per the
Asbestos Coordinator.
