General Measures: Remove patient from area of exposure.

INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek immediate medical attention.

INGESTION: Rinse mouth with water. Do not induce vomiting. Seek immediate medical attention. Never induce vomiting or give anything by mouth to an unconscious person.

SKIN: Remove contaminated clothing, wash affected area with soap and water. Seek medical attention. Wash contaminated clothing before reusing.

EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention.

Most Important Symptoms/Effects, Acute and Delayed: May cause irritation, headache, nausea, vomiting, abdominal spasms. See section 11 for more information.

Indication of Immediate Medical Attention and Special Treatment: No other information available.




Extinguishing Media: Use suitable extinguishing agent for surrounding materials and type of fire.

Unsuitable Extinguishing Media: No information available.

Specific Hazards Arising from the Material: May release toxic fumes under fire conditions.

Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing when necessary.




Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes. Eliminate all sources of ignition.

Methods and Materials for Containment and Cleaning Up: Avoid raising dust. Cleanup spills with a vacuum system utilizing a high efficiency particulate air (HEPA) filtration system and place in a closed container for further handling and disposal.

Environmental Precautions: Do not allow to enter drains or to be released to the environment.




Precautions for Safe Handling: Handle in an enclosed, controlled process. Handle in a well-ventilated area. Avoid creating dust. Avoid exposure to high temperature. Avoid breathing dust or fumes. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.

Conditions for Safe Storage, Including Any Incompatibilities: Store material tightly sealed in properly labeled containers. Store in a cool, dry area. Protect from moisture. Do not store together with oxidizers. See section 10 for more information on incompatible materials.




Exposure Limits:           OSHA/PEL:        ACGIH/TLV:

Lead, inorganic (as Pb)     50 µg/m3            0.05 mg/m3

Appropriate Engineering Controls: When working with finely divided powders, handle in a controlled, enclosed environment. Use good housekeeping and sanitation practices. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air. Clothing worn in areas of exposure to lead dust or fume should be restricted to the workplace and laundered regularly.

Individual Protection Measures, Such as Personal Protective Equipment:

   Respiratory Protection: When potential exposures are above the occupational limits, approved respirators must be used.

   Eye Protection: Safety glasses

   Skin Protection: Wear impermeable gloves, protective work clothing as necessary.

Acute and Chronic Effects

Lead Compounds:  Acute lead poisoning is relatively infrequent and occurs from ingestion of acid soluble lead compounds or inhalation of lead vapors. Chronic lead poisoning may affect the gastrointestinal, neuromuscular, central nervous, hematological and renal systems. The CNS syndrome is usually more common among children, while the GI syndrome is more prevalent in adults. There is limited evidence in humans and sufficient evidence in experimental animals for the carcinogenicity of inorganic lead compounds. Animal studies have demonstrated effects of lead on male and female gonads and fertility.
