The increasing incidence of occupational intoxication is discussed with reference to heavy metals, air pollutants, and organic compounds. Acetylene (74862), a gas of low toxicity, has a lethal concentration (5-10 minute inhalation) of approximately 500,000ppm, a toxic concentration of 250,000ppm, and a tolerable concentration (the latter two for 30 minute to one hour inhalations) of 100,000ppm. Severe poisoning of workers has occurred during purification of acetylene using special washing devices filled with oxidizing agents such as chloride of lime and chromic-acid (7738945). Principal symptoms include peripheral facial nerve paralyses, loss of taste and smell, corneal ulceration, and difficulties in chewing and swallowing. Lewisite and dichloroethyl-sulfide, formed by reaction of acetylene with arsenic-trichloride (7784341) and sulfur-chloride (10025679), dull the senses of taste and smell, thus impairing the perception of danger.
