Lead-Containing Materials Guidelines

7 Lead-Containing Materials may have already developed by the time high blood lead levels are identified and treated, making avoidance to exposure and medical surveillance extremely important. Acute lead poisoning symptoms may include abdominal pain, irritability, fatigue, weakness and muscle pain. In rare instances, damage to the brain and central nervous system also may occur. Chronic lead poisoning may result after lead has accumulated over time in the body and has been deposited in bone. Stored lead in bone may be released to the blood stream to produce health effects including defective hemoglobin synthesis, nervous system abnormalities, hypertension, effects in the reproductive system and damage to a developing fetus. The measurement of blood lead level is the most reliable method of evaluating lead exposure. It indicates the amount of lead in the bloodstream, which is often a measure of recent exposure to lead. Per the United States Centers for Disease Control and Prevention (CDC) , experts use a reference level of 5 micrograms per deciliter (µg/dl) to identify children with blood lead level of concern. Per the United States Department of Labor Occupational Health and Safety Administration (OSHA) , employees whose blood lead level is at or above 40 µg/dl shall be notified. OSHA also requires temporary medical removal from lead related activities when blood levels excess 60 µg/dl. Training All ISU employees involved in the disturbance of lead-containing materials and lead-based paint as part of regular work activities must have a lead awareness training class. ISU employees exposed to lead above the action level (A.L.) of 30 µg/m 3 must have additional training and medical surveillance. Typical job classifications needing awareness training would include painters, carpenters, welders, electricians, plumbers, and general maintenance personnel. Employees involved in lead abatement activities must receive more extensive EPA approved lead abatement training. Register online at Learn@ISU for an upcoming Lead Awareness Training.
