Health hazard evaluation report no. HETA-87-232-1948, Consolidated Freightways, Pocono Summit, Pennsylvania.
NIOSH 1989 Feb; :1-23
In response to a request from the International Brotherhood of Teamsters, Chauffeurs, Warehousemen and Helpers of America, a study was made of possible hazardous working conditions at Consolidated Freightways (SIC-4213), Pocono Summit, Pennsylvania. The request concerned potential exposure of dock workers to exhaust emissions from diesel powered forklift trucks brought about by the health complaints of several of the workers there. The Pocono Summit terminal occupied a very long, relatively narrow building of steel. Most of the floor space was devoted to the dock area. Twenty one workers were identified as symptomatic of exposure to diesel exhaust fumes. This included at least half of the midnight shift. Upper respiratory tract irritation was mentioned by all of these workers. Some reported eye irritation, cough productive of black tinged sputum, and sore throat. These symptoms lessened during periods away from work. Airborne concentrations of all components measured at the site were well below the applicable exposure limits. The authors conclude that a potential health hazard associated with exposure to diesel engine exhaust existed. The authors recommend that whenever a forklift truck is to be left unattended for more than the shortest of periods, the motor should be turned off. The newer forklifts should be used on a shift before the older, less emission controlled, lifts. Roof exhaust fans which have been ordered are to be installed at the facility and their effectiveness evaluated.
