Appendix F to 1926.56--Work Practices and Engineering Controls for Major. Asbestos Removal, Renovation, and Demolition Operations--Non-Mandatory This is a non-mandatory appendix designed to provide guidelines to assist hygiene facilities that ensure that their asbestos contaminated employees do not leave the work site with asbestos on their persons or clothing; the construction of those facilities is also described below. The steps in the process of preparing the asbestos removal site, building the enclosure, constructing hygiene facilities, removing the asbestos-containing niatertal. and restoring the site include: (1) Planning the removal project: (2) Procuring the necessary materials and equipment; (3) Preparing the-work area;. (4) Removing the asbestos-containing material: (5) Gleaning the work area; and (6) Disposing of the asbestos-containing waste. Manning the Removal Project The planning of an asbestos removal project is critical to completing the project safely and cost-effectively. A written asbestos removal plan should be prepared that describes the equipment and procedures Although individual asbestos removal projects vary in terms of the equiprrient required to accomplish ihe removal of the material, some equipment and materials are common to most asbestos removal operations. Equipment and materials that should be available at Ihe beginning of each project are: (1) rolls of polyethylene sheeting: (2) rolls of gray duct tape or clear plastic tape; (3| I IEPA filtered vacuum(s): (4) HF.I'A- * filtered portable ventilation systcm(s): (5) a welting agent; (6) an airless sprayer; (7J a portable shower unit; (8) appropriate respirators: (9) disposable coveralls: (10) signs arid labels: (11) pre-printed disposal bags: and (12) a manometer or pressure gauge. Rolfs of Polyethylene Pluslic and Tape. Rolls of polyethylene plastic (6 mil in thickness) should be available to.construcl the asbestos removal enclosure and to seal windows, doors, ventilaiion systems: wall penetrations, and ceilings and floors in the work area. Cray duct tape or clear plastic tape should be used to seal the edges of the plastic und to seal any holes in the plastic enclosure. Polyethylene plastic sheeting can be purchased in rolls up to 12-20 feet in width employers in complying with the that will be used-throughout the project The and up to 100 feet in length. requirements of 29 GFR 1920.58. Specifically, - asbestos abatement plan will aid not only in HEPA-Filtered Vacuum.

The asbestos abatement plan should contain the following information: A physical description of the work area: HEPA (High Efficiency Particulate Air) filler, which is capable of removing 99.97 percent of the asbestos particles from the air. Various sizes and capacities of HEPA vacuums are available. One manufacturer. Nilfisk of America. Inc.*, produces three models that range in capacity from 5.25 gallons (o 17 gallons (sec Figure F-1).
