In response to a request by the factory manager and United Paperworkers Union local 1467 to investigate employee complaints of headaches and eye and throat irritation associated with operation of hand and automatic wax lines, an evaluation was made at Kardon Industries Composite Can and Tube Division (SIC-2655), St. Paris, Ohio. The study focused on an amorphous polypropylene wax used on wax lines along with air samples for organic vapors, aldehydes, ketones, carbon-monoxide (630080), and carbon-dioxide (124389). Relatively low levels of several hydrocarbons were found, with n- hexane (110543) present in highest concentrations relative to occupational hygiene criteria, being measured at 28.7mg/m3. While no furfural was detected, all samples contained formaldehyde (50000) and acetaldehyde (75070). Both aldehydes were also detected as decomposition products of the wax. The supplier of the wax stated that it gave off ketones, aldehydes, and eventually carboxylic acids when it was heated. Employees reported symptoms of headache, burning eyes, throat and nose irritation, dizziness, and an altered sense of taste and nausea. Aldehydes were considered to be the causative agents of these conditions. Recommendations included improvements in the ventilation system with periodic evaluations to be made, modification in the method of manually adding wax to melt tanks, and reduction in airborne concentration of wax decomposition products.
