–  Install  or  remove  electrical  cables  through  or near  asbestos-containing  materials. Personal Protective Clothing Personnel  who  handle  asbestos-containing materials where the concentration of airborne fibers is likely  to  exceed  the  PEL  should  wear  protective clothing. Be sure all openings are closed and that the garment fits snugly around your neck wrist, and ankles. Tape the junctions at the wrist, ankles, and collar as necessary  to  prevent  skin  contamination.  The  following paragraphs  list  recommended  items  and  precautions: l l l l l Wear  a  full-body,  one-piece,  disposable  coverall preferably  made  of  Tyvek  or  a  comparable substitute.  Use  a  Tyvek  coverall  with  attached hood  if  possible. Hoods should extend beyond the collar of the overall and completely protect the neck. The hood should be made of Tyvek or a comparable substitute. Wear  medium-weight  rubber  gloves  and  a  thin cotton “under glove” to absorb perspiration. Wear slip-resistant plastic shoe covers or heavy polyethylene  shoe  covers  with  slip-resistant soles or lightweight rubber boots. Wear  face  shields,  vented  goggles,  or  other appropriate eye protection equipment whenever there is a possibility of eye irritation. Respiratory Protection When  you  are  doing  asbestos  work  and  the concentration of airborne fibers is unknown, wear a full-facepiece,  continuous-flow  coupled  air  respirator. The  Ambient  Air  Breathing  Apparatus  meets  this requirement.  Personnel  who  are  not  working  on asbestos but are in the space for other reasons should wear  at  least  a  half-mask  air  purifying  respirator equipped with a high-efficiency filter. Warning  Signs  and  Labels The command should display warning signs at each location  where  concentrations  of  airborne  asbestos fibers may exceed the PEL. Post the signs at a distance from the area to warn anyone who may be approaching. The signs may include a list of the protective equipment required for the area. The sign should contain at least the  following  information: DANGER, ASBESTOS. CANCER AND LUNG DISEASE HAZARD. AUTHORIZED PERSONNEL  ONLY.  RESPIRATORS  AND P R O T E C T I V E    C L O T H I N G    A RE REQUIRED IN THIS AREA. There  may  be  conditions  where  containers  of  raw materials, mixtures, scrap, waste, debris, and other products   containing   asbestos   could   increase   the surrounding levels of airborne asbestos fibers. If so, place warning labels on the containers in letters that are visible and legible. The labels should contain at least the following   information: DANGER,   CONTAINS   ASBESTOS FIBERS.   AVOID   CREATING   DUST. CANCER   AND   LUNG   DISEASE HAZARD. Workplace  Release  Criteria There are a few simple but necessary guidelines you should  follow  before  you  reoccupy  a  space  where asbestos work has been done. Conduct a critical visual inspection after clean-up to be sure the area is clean and free of visible asbestos dust. The safety officer must conduct  the  inspection  after  emergency  or  operational readiness repairs at sea. Do not release an asbestos controlled  area  for  unrestricted  access  nor  for  air sampling until the area has first been thoroughly cleaned and inspected. Use local exhaust ventilation if necessary to be sure the atmospheric levels of asbestos do not exceed  PELs. DISPOSAL PROCEDURES There are a few simple but important guidelines you should follow to dispose of asbestos waste. Be sure the waste  is  wet  if  conditions  justify.  Double-bag  the  waste in   heavy-duty   plastic   bags   or   other   suitable impermeable  containers  that  are  color-coded  for  easy recognition. Be sure all bags or containers have standard asbestos warning labels. Be careful that bags and other containers do not rupture when they are transported to a  shore  activity  for  disposal. For guidance concerning specific health-related precautions  to  be  used  for  specific  operations,  consult the  cognizant  industrial  hygienist. ENVIRONMENTAL  PROTECTION  LAWS Repairs  done  at  sea  are  not  subject  to  the Environmental Protection Agency’s (EPA) emission 10-3
