To K.D. ABDEEHS From E.E. Hang Copies : c.j. Chen; File; Chron Subject : uqwsikui hycikhk sukvbt Date: August 19* 1985 A coopidiauiTC Industrial hygiene survey far your plant, will be conducted during the week of August 26, 1985. The various airborne contaminants to be sampled/analysed will be the sane as those of lost year (i.e. asbestos, VCM, organic solvents, and noise, etc.) The total sampling tine for each airborne contaminants vill be around four boors. The total number of samples to be taken this time is 95, vhich con be broken down as followsi Asbestos t Bespiroble Silica Dnsti CHs Organic Vaporsi C0> Boise: 41 16 9 8 6 15 Sue to the change in plant operating conditions, however, yon nay have some new established stations to be sampled. If this is the case, exchange those old sampling stations having good track records for the new established stations, so that the total sampling number can be maintained around 95. To ovoid unnecessary resampling caused by poor ventilation, please carefully check your ventilation systems before the actual sampling dote. Hake certain that all ventilation systems are in good operating conditions. As mentioned by same Plant Managers, the areas handling HB (methyl Ethyl Ketone), Methylate Chloride, and/or Cyclohexanone are MS ventilated. TO find oat that the airborne concentrations of these contaminants ore belov the OSHA's PELs, be sore to ask the Industrial hygienist to sample those areas.
