Control Technology Assessment for Coal Gasification and Liquefaction Processes, BI-GAS Pilot Plant, Homer City, Pennsylvania, Report No. CT-119-17a.
A control technology survey was conducted at the BI GAS pilot facility (SIC-1211) in Homer City, Pennsylvania on August 16 and 17, 1979. The BI GAS coal gasification process was an important emerging technological development in the gasification of coal to a high heat fuel. Potential hazards included noise, fire, coal dust, carbon-dioxide (124389), carbon-monoxide (630080) (CO), methane (74828), char, hydrogen (1333740), hydrogen-sulfide (7783064), naphthalene (91203), trace metals, phenols, nickel-carbonyl (13463393), and mercaptans. The safety policy at the facility stressed minimal activity in the gasifier structure and was effective in reducing exposures to process contaminants from leaks. Other control measures included CO monitors with alarms, self contained breathing apparatus for emergency use, and a 5 minute escape air pack respirator. Employees received a safety policies and procedures manual. Safety training sessions and monthly meetings were held. Fire prevention, accident prevention, chemical handling, emergency procedures, and first aid procedures were emphasized. Annual physical examinations were given. The authors conclude that the major weakness of the medical program is the absence of a preemployment physical examinations. Periodic skin examinations are recommended to reduce skin irritations and to detect possible exposures to polynuclear aromatics.
