Abstract
A walk through survey was conducted to assess a phosphorus products manufacturing facility at Mobile Chemical Company (SIC-2819), Charleston, South Carolina in December 1983. The facility produced phosphorus-trichloride (7719122) (PT). The primary engineering control was a water scrubber to remove PT vapors from gas streams moving at 1000 to 5000 cubic feet per minute. The acidic solution resulting from the scrubber operation was neutralized by sodium- hydroxide and then sent for waste water treatment. Double mechanical seals were used to prevent PT leaks from pumps, valves, and piping. All storage tanks were constructed of nickel coated steel. Sampling ports for product quality control were equipped with ventilated sample hoods. Ambient air was continuously monitored for hydrogen- sulfide (7783064) and organophosphorus compounds. Five percent of the finished product was stored in 50 gallon plastic drums in a partially enclosed shed, and was then shipped. Workers were required to wear respirators, protective outer garments, and gloves. Eye washers and safety showers were available. Monthly safety meetings were held. The author concludes that the facility has adequate, though not outstanding, control technology. The drumming operation poses a potential exposure hazard due to its being labor intensive.
