Hazards and Protection.
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Add dilute caustic soda (NaOH). If dissolved, apply sodium sulfide (Na2S) solution to precipitate heavy metals. If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. Allow to aerate.
Stable under normal temperatures and pressures.
Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates Mixtures with phosphorus, tin(II) chloride, or other reducing agents
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
These substances will accelerate burning when involved in a fire.
May explode from heat or contamination.
Vapors from fire may contain toxic mercury and oxides of nitrogen.
TLV (as Hg): ppm; 0.1 mg/m3 (skin) (ACGIH 1991-1992).
Initial effects of ingestion are gastric irritation with nausea, vomiting and abdominal pain.
Respiratory depression and cyanosis may be noted, due to methemoglobinemia.
Cyanosis that minimally responds to oxygen therapy may be noted, and is indicative of probable methemoglobinemia.
Immediate life support measures should be provided because of associated hypotension, seizures, and methemoglobinemia-induced anoxia. Ipecac induced vomiting is not recommended because of the potential for seizures.
Move patient to fresh air. Monitor for respiratory distress. Administer oxygen and assist ventilation as required. Treatment should include recommendations listed in the oral exposure section when appropriate.
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
