Title Warehouse workers' headache - Carbon monoxide poisoning from propane-fueled forklifts
Bibliographic information Jan. 1992, Vol.34, No. 1, p.12-15. 7 ref.
Abstract The study examines 17 patients treated for acute carbon monoxide (CO) poisoning resulting from the indoor use of propane-fuelled forklifts. All patients had neurological symptoms or persistent headache and were given hyperbaric oxygen to relieve their symptoms. The concentration of CO in the exhaust emissions of 12 forklifts at five separate sites was investigated. The average CO concentration in the exhaust during engine idling was 36,000ppm (3.6%). This value decreased slightly to 30,000ppm (3.0%) at working engine speed. Measurements of exhaust flow indicate CO production rates of approximately 60L/min at working engine speed. These quantities of CO constitute a significant occupational risk to workers using propane-fuelled forklifts in unventilated indoor environments.
