ACUTE HAZARDS | PREVENTION | FIRE FIGHTING | |
---|---|---|---|
FIRE & EXPLOSION | Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with incompatible substances. See Chemical Dangers. | NO contact with incompatible materials: See Chemical Dangers | In case of fire in the surroundings, use appropriate extinguishing media. |
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! | |||
---|---|---|---|
SYMPTOMS | PREVENTION | FIRST AID | |
Inhalation | Cough. | Use local exhaust or breathing protection. | Fresh air, rest. |
Skin | Protective gloves. Protective clothing. | Rinse and then wash skin with water and soap. | |
Eyes | Redness. | Wear safety goggles or eye protection in combination with breathing protection if powder. | Rinse with plenty of water (remove contact lenses if easily possible). |
Ingestion | See Effects of short-term exposure | Do not eat, drink, or smoke during work. | Rinse mouth. Give one or two glasses of water to drink. |
SPILLAGE DISPOSAL | CLASSIFICATION & LABELLING |
---|---|
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Vacuum spilled material with specialist equipment. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. |
According to UN GHS Criteria DANGER
May cause cancerMay damage fertility or the unborn child if inhaled May cause damage to organs through prolonged or repeated exposure Very toxic to aquatic life with long lasting effects Transportation |
STORAGE | |
Separated from food and feedstuffs and incompatible materials. See Chemical Dangers. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. | |
PACKAGING | |
Unbreakable packaging. Put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs. |

TLV: (as Cr(VI), inhalable fraction): 0.0002 mg/m3, as TWA; 0.0005 mg/m3 as STEL; (DSEN); (RSEN); A1 (confirmed human carcinogen); BEI issued. TLV: (as Pb): 0.05 mg/m3, as TWA. EU-OEL: (as Cr): 0.005 mg/m3 as TWA; (see Notes). EU-OEL: (as Pb): 0.15 mg/m3 as TWA; (binding): BLV issued. MAK: (inhalable fraction): carcinogen category: 1; germ cell mutagen group: 2 |
ENVIRONMENT |
---|
Bioaccumulation of this chemical may occur along the food chain. The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. |
NOTES |
---|
Chromates are classified as human carcinogens, but evidence for this substance is limited. Lead chromate pigments may contain appreciable quantities of water-soluble lead compounds. Toxic fumes (lead and chromium compounds) are also liberated during welding, cutting and heating of material treated with lead chromate. Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. Lead chromate occurs in nature as the minerals crocoite, phoenicochroite. NEVER use a domestic-type vacuum cleaner to vacuum the substance, only use specialist equipment. EU-OEL limit value 0.010 mg/m3 until 17 January 2025. Limit value: 0.025 mg/m3 for welding or plasma cutting processes or similar work processes that generate fume until 17 January 2025. |
