Excessive airborne concentrations may obscure vision and present an inhalation and ingestion hazard. Spill materials and associated run-off should not be allowed to reach waterways. Danger of cumulative effects. Product may irritate eyes and skin. May be harmful if swallowed.

Potential Acute Health Effects

EYE CONTACT: Exposure can cause eye irritation. SKIN CONTACT: May cause skin irritation. INGESTION: Can cause gastrointestinal irritation, nausea, vomiting and diarrhea. May cause kidney damage. Symptoms similar to those caused by inhalation may occur. INHALATION: May cause respiratory irritation. Inhalation is the main route of lead intoxication. Symptoms may not develop quickly, therefore there may be no immediate effects of exposure. The effects of overexposure to lead may include decreased physical stamina, fatigue, sleep disturbance, headaches, aching bones and muscles, constipation, abdominal pains, and decreased appetite. Inhalation of large amounts may cause seizures, coma or possibly death.
