Hazards and Protection.
Do not store near combustible materials. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid ingestion and inhalation. Keep away from clothing and other combustible materials. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Avoid generating dusty conditions. Provide ventilation. With a clean shovel, carefully pick up the material and place it into a clean dry container and cover for disposal. Keep combustibles (wood, paper, oil, etc.,) away from spilled material.
Stable under normal temperatures and pressures.
Azodyestuffs (e.g. dinitroaniline orange and chlorinated para red), aluminum + dinitronaphthalene, sulfur tantalum, iron (III) hexacyanoferrate (4-), hydrazine, hydrogen peroxides, active metals, sodium, potassium, reducing agents.
Irritating and toxic fumes and gases, lead/lead oxides.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Combustion generates toxic fumes. Oxidizer. Greatly increases the burning rate of combustible materials. May accelerate burning if involved in a fire. Extinguishing media: Use water only! Cool containers with flooding quantities of water until well after fire is out. For large fires, flood fire area with water from a distance. DO NOT use dry chemicals, carbon dioxide, Halon or foams.
Flammability and Flash point data are unavailable; this compound is probably non-flammable.
Dangerous; when heated it emits highly toxic fumes.
TLV: ppm; 0.05 mg/m3 (as TWA) A2 as Pb (ACGIH 1991-1992) TLV (as Cr): 0.012 mg/m3 A2 (ACGIH 1991-1992)

May cause cancer in humans. Repeated exposure may cause sensitization dermatitis. Chronic exposure to lead may result in plumbism which is characterized by lead line in gum, headache, muscle weakness, mental changes, Laboratory experiments have resulted in mutagenic effects. Lead salts have been reported to cross the placeta and induce embryo- and feto- mortality.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Many lead compounds can cause toxic effects in the blood-forming organs, kidneys and central nervous
Causes respiratory tract irritation. May cause effects similar to those described for ingestion.
Causes skin irritation.
Causes eye irritation.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
