Asbestos Work Procedures Description*
| Procedure | Description (Highlights) |
| Brake & Clutch |
Work practice methods are listed including NPE/HEPA vacuum system method, low pressure wet cleaning method, equivalent
methods and wet methods in which no more than 5 pairs of brakes or clutches are handled per week. Additional guidance is also provided for light and large
trucks. Non-asbestos replacement guidance as well as identification advice is also offered.
|
| Cable |
This work practice addresses regulatory requirements when handling ACM wrapped cable in manholes or vaults. It includes general
work practices plus specific procedures when repairing or removing intact ACM wrapped cable with an NEA as well as without an NEA in place.
|
| Class IV |
Includes general work practices for Class IV work activities including working in a ceiling plenum space where surfacing ACM is
present, sweeping, dusting, mopping, cleaning and vacuuming ACM, stripping and buffing of resilient flooring, installing a partition over resilient asbestos
flooring, installing a smoke detector above a suspended ceiling near ACM pipe lagging or ACM surfacing material, work practices where a worker may
contact but not disturb asbestos such as painting over ACM drywall and a variety of instances where a small piece of suspect intact ACM is found such as a
broken or chipped floor tile, ceiling tile or pipe insulation.
|
| Control Wire |
Includes general work practices and specific practices when repairing or removal of intact ACM control wire with an ACM inner
jacket and an NEA is in place. Work practices are also included for removal or repair of non-intact (friable) control wire without an NEA.
|
| Floor Tile |
Includes general work practices and practices for removal of intact vinyl asbestos floor tile and mastics plus indoor, non-intact work,
maintenance and repair (Class III) work, care and maintenance of ACM resilient flooring. This work practice also includes state variances for all floor tile work.
|
| Gasket & Packing |
Includes both general and prescriptive work practices when handling ACM gasket and packing materials in pipe flanges, turbine and
pump casings, valve plate covers on reciprocating pumps, valve and gland packing, boiler hatches, tray gaskets inside vessels and other miscellaneous
applications. These practices also cover removal of intact materials with an NEA, removal of non-intact (friable) materials with an NEA, removal of gasket
and packing materials with insufficient data for an NEA, and removal of materials above the PEL or EL.
|
| Glovebag |
This work practice first describes the differences among glovebags, negative air glovebags and gloveboxes. It also addresses which
regulations apply, rules on who are allowed to work with glovebags, a how to section, a discussion around protective measures that should be employed and
a detailed look at prescriptive work practices including guidance on waste disposal and documentation requirements.
|
| HEPA Vacuum Changeout |
This procedure covers requirements for changing a filter or a bag in a HEPA vacuum used for asbestos clean-up activities. It includes
general and specific requirements using localized engineering controls including a glovebag or a mini-containment.
|
| Panel Boards |
These procedures address regulatory requirements for drilling, removing or otherwise disturbing ACM control panel boards. In
addition to general work practices, procedures for removal with an NEA, Class II work intact work without an NEA or above the PEL are included. Also,
non-intact work, and Class III, maintenance and repair work are covered.
|
| Plenum Space |
These procedures cover regulatory requirements where wiring, cable or conduit are being installed in a ceiling plenum where ACM is
present. Specific work practices are included for the following work activities: installing new conduit attached to existing brackets in an air plenum, rerouting
conduit that can be attached to existing support brackets, installing new plenum rated computer or telephone cable that will lay on top of either a clean or
dusty ceiling tile or grid panel. Guidance for moving a non-asbestos ceiling tile panel below a plenum space with exposed asbestos surfacing materials is also
covered.
|
| Thermocouple Wire |
This procedure covers regulatory requirements when disturbing ACM thermocouple wire materials. It includes general work practices
as well as work practices when removing or repairing intact and non-intact materials, both with an NEA and without a negative exposure assessment (NEA)
in place.
|
| Transite |
Includes general work practices and practices for Outdoor Class II intact with NEA-expected exposure below 0.01f/cc (clearance
level), outdoor Class II intact work with NEA-expected exposures between 0.1f/cc and 0.01f/cc (between the PEL and clearance level), outdoor Class II
intact work with exposure assessments above the PEL 0.1f/cc, indoor Class II intact work, lab table tops/chalk boards/fume hoods, transite wall and ceiling
panels, electric mounting boards in closets, switchgear, motor control centers (MCC's) and miscellaneous control panels, electric conduit, water pipes or
halfround electric raceway trays, underground water pipes and conduits, outdoor, non-intact Class I work, indoor non-intact Class I work and maintenance
and repair (Class III) work.
|
| Refractory Ceramic Fibers |
This procedure is more of an Industrial Hygiene guideline than the above work procedures. Since RCF's are unregulated at this
time but may become a regulated material in the near future, these guidelines need to be looked at as best practices versus regulatory requirements. The
guideline includes a policy statement, recommended exposure levels and acceptable exposure limits, health effects, personal protective equipment guidance,
housekeeping, hygiene, training, monitoring and waste disposal requirements. Other recommendations are included when handling RCF's during either
fabrication, installation, removal or demolition activities.

*General Description
Each asbestos procedure covers repair, maintenance and removal work practices. These procedures are formatted into several sections such as 1) Background,
2) Regulatory Overview 3) Pre-Work Activities and Requirements. Each procedure also includes general and prescriptive step by step work practices.
