CAS Registry No.: 7439-92-1
Other Names: Elemental Lead, Lead metal, Inorganic lead
Main Uses: Manufacture of many products including storage batteries and ammunition, in construction materials, in solders and alloys, etc.
Appearance: Blue - grey lustrous solid.
Canadian TDG: Not specifically listed in Canadian TDG Regulations, but may be regulated as part of a chemical family or group Not Otherwise Specified (N.O.S.). Consult the regulations.
D2A - Very Toxic (Chronic toxicity; Teratogenicity/embryotoxicity; Carcinogenicity; Mutagenicity; Reproductive toxicity)
Emergency Overview: Blue - grey lustrous solid. Odourless. COMBUSTIBLE DUST. Dust may form explosive dust-air mixture. VERY TOXIC. Prolonged or repeated exposure causes damage to nervous system, kidneys, blood. if inhaled and/or ingested. SUSPECT CANCER HAZARD. Suspected of causing cancer. REPRODUCTIVE HAZARD. May damage fertility. TERATOGEN/EMBRYOTOXIN. May damage the unborn child. MUTAGEN. May cause genetic defects.
Main Routes of Exposure: Inhalation. Skin contact. Eye contact. Ingestion.
International Agency for Research on Cancer (IARC): Group 2B - Possibly carcinogenic to humans. Inorganic lead compounds are Group 2A - Probably carcinogenic to humans.
American Conference for Governmental Industrial Hygienists (ACGIH): A3 - Confirmed animal carcinogen.
Inhalation: Take precautions to ensure your own safety before attempting rescue (e.g. wear appropriate protective equipment). Move victim to fresh air.
Skin Contact: Quickly take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Quickly and gently blot or brush away excess chemical. Wash gently and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 5 minutes.
Eye Contact: Avoid direct contact. Wear chemical protective gloves if necessary. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 5 minutes, while holding the eyelid(s) open. If irritation or pain persists, see a doctor.
Ingestion: Have victim rinse mouth with water. Call a Poison Centre or doctor if the victim feels unwell.
First Aid Comments: If exposed or concerned, see a doctor for medical advice. All first aid procedures should be periodically reviewed by a doctor familiar with the chemical and its conditions of use in the workplace.
Note to Physicians: Some jurisdictions specifically regulate an ingredient of this product and require a complete medical surveillance program. Specific information should be sought from the appropriate government agency in your jurisdiction.
Flammable Properties: Does not burn. (lead metal) COMBUSTIBLE DUST. Powder may form explosive dust-air mixture.
Suitable Extinguishing Media: Not combustible. Use extinguishing agent suitable for surrounding fire. (lead metal).
Specific Hazards Arising from the Chemical: In a fire, the following hazardous materials may be generated: very toxic lead oxides.
Personal Precautions: Keep unnecessary and unprotected personnel out of spill area. Do not touch damaged containers or spilled product unless wearing appropriate protective equipment.
Methods for Containment and Clean-up: Small spills or leaks: collect using shovel/scoop or approved HEPA vacuum and place in a suitable container for disposal. Large spills or leaks: contact emergency services and manufacturer/supplier for advice.
Other Information: Report spills to local health, safety and environmental authorities, as required.
Handling: Avoid generating dusts. In event of a spill or leak, immediately put on escape-type respirator and exit the area. Good housekeeping is extremely important. Prevent dust accumulation on ALL surfaces including ceiling rafters and other hidden surfaces.
Storage: Store in an area that is: cool, dry, well-ventilated, out of direct sunlight and away from heat and ignition sources. Keep amount in storage to a minimum.
ACGIH® TLV® - TWA: 0.05 mg/m3 A3 BEI®
Exposure Guideline Comments: TLV® = Threshold Limit Value. TLV® = Threshold Limit Value. A3 = Animal carcinogen.BEI® = Biological Exposure Index.
NOTE: In many (but not all) Canadian jurisdictions, the exposure limits are similar to the ACGIH® TLVs®. Since legislation varies by jurisdiction, contact your local jurisdiction for exact details. A list is available in the OSH Answers on Canadian Governmental Occupational Health & Safety Departments.
A list of which acts and regulations that cover exposure limits to chemical and biological agents is available on our website. Please note that while you can see the list of legislation for free, you will need a subscription to view the actual documentation.
Engineering Controls: Use a local exhaust ventilation and enclosure, if necessary, to control amount in the air. Use stringent control measures such as process enclosure to prevent product release into the workplace.
Eye/Face Protection: Wear chemical safety goggles.
Skin Protection: Wear chemical protective clothing e.g. gloves, aprons, boots.
Up to 0.5 mg/m3:
(APF = 10) Any air-purifying respirator with an N100, R100, or P100 filter (including N100, R100, and P100 filtering facepieces) except quarter-mask respirators; or Any supplied-air respirator.
APF = Assigned Protection Factor
Recommendations apply only to National Institute for Occupational Safety and Health (NIOSH) approved respirators. Refer to the NIOSH Pocket Guide to Chemical Hazards for more information.
General Hygiene Considerations: It is good practice to: avoid breathing product; avoid skin and eye contact and wash hands after handling.
