This pamphlet provided information on working with lead (7439921), including industries which use lead, chronic and acute lead poisoning, methods for controlling lead exposure, symptoms which should be reported, and what workers should do to reduce exposures to lead. Most of the cases of industrial lead poisoning arose due to the inhalation of lead dust or fumes in the atmosphere. Symptoms of lead poisoning included a burning sensation in the mouth, stomach pain, nausea, vomiting, and constipation or diarrhea. In most cases, lead accumulated in the body over long periods of time. Methods of preventing lead poisoning included engineering, processing, environmental, medical, and hygienic protective measures. Adequate ventilation and exhaust systems were particularly important. Workers could rely on respirators during specific periods of time, but this should be only temporary. The temperature of molten lead should be kept close to the melting point and the exposed surface areas of the processing vats should be kept covered as much as possible. Air quality should be continually monitored and physical examinations of workers should occur routinely. Special work clothes and facilities for showering should be provided. Workers should avoid alcohol consumption as alcohol increases the lead absorption potential. Whenever consulting a physician the employee must reveal that he works in an industry where exposure to lead is possible.
