C ASBESTOS DUST INHALATION 2 May 5 and 6 Conference we Information presented showed asbestos dust inhalation | to be a more serious hazard than has previously been realized ". High concentrations asbestos dust occur when handling pipe - and tank insulation particularly removing old insulation tbh '. These concentrations can cause Fibrosis Asbestosis Pulmonary "7" Carcinoma and Mesothelioma Cancer to the lungs or chest cavity Statistically cigarette smokers are most susceptible Haskell Laboratory is conducting an evaluation of the health problems related to handling asbestos The evaluation will be complete and published within the next few months Information presented below is recommended to be used by our ~ plants as a guide in establishing safe work procedures until more complete information is available Guidelines are @ Asbestos workers should be given a pulmonary function test as part of employee's normal physical examina- tion Followup testing is recommended every year The Jones Pulmonor Function Testing Machine is recommended approximately 230.00 Additional information can be obtained from Wilmington Medical X X @ Inform employees working with asbestos insulation of the related health problems This should be handled without unduly alarming people @e Substitute other types of insulation for asbestos when practical @ Prevent unnecessary dust through careful handling when opening cartons etc. @ Provide a separate room for primary sawing operation Enclose electric cutoff saws with clear lucite An Oe industrial type vacuum cleaner attached to the saw Om with disposable bags for burying is helpful Clean ng room with vacuum often using dust respirator for neg . personal protection Sas eee tm @ Wet old insulation before removing and wear a MSA Dustfoe 77 Respirator * Five fibers of air is considered to be a safe limit in a work area for 8 hours 001336 wed GW GW -2 = a, May 5 and 6 1970 Conference . at Mix ground asbestos in plastic bags AV insulators personnel where @ Restrict access to areas MONI A~ @ Minimize the application of asbestos by spray methods When spraying is necessary the following requirements should be met a) The spray area be completely enclosed by tarpaulins Ri) b Area be cleaned after application and > c The sprayed asbestos insulation in air circulation plenums or ducts be coated with a sealant to preclude eroded asbestos from getting into the air of the building 2. tee g +4 eam * 3. ee ys Pe
