Abstract
A study was made to evaluate control measures used during the removal of lead (7439921) based paint at the BP Oil Corporation (SIC- 2911), Lima, Ohio. For abrasive blasting, a staurolite sand (Starblast-XL) was being used. A containment had been erected while lead based paint was being removed from the Treated Gas Knock Out Tank (TGKO) in the Sulfur Recovery Unit. Even though exhaust ventilation provided for rapid decay of dust levels when blasting stopped, it was not sufficient to control airborne dust and lead concentrations within the containment during abrasive blasting and blowdown. Airborne levels were 22,000 micrograms/cubic meter, greatly exceeding the recommended limits. The blaster was adequately protected by the type CE respirator he was wearing. Excellent work practices were also observed and contributed greatly to his safety. The authors recommend that other commercially available abrasives, containing less silica (14808607), be used in the blasting inside containment.
