Hazards and Protection.
Keep tightly closed.
Compatible chemical-resistant gloves. Chemical safety goggles. Hand: Faceshield (8-inch minimum).
Government approved respirator.
Cover with dry lime or soda ash, pick up, keep in a closed container, and hold for waste disposal. Ventilate area and wash spill site after material pickup is complete.
Stable at normal temperatures and pressures. Moisture
Strong oxidizing agents, Strong bases.
Carbon monoxide, Carbon dioxide, Sulfur oxides, Hydrogen chloride gas.
Extinguish using Carbon dioxide, dry chemical powder, or appropriate foam. Unsuitable: Do not use water. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Water hydrolyzes material liberating acidic gas which in contact with metal surfaces can generate flammable and/or explosive hydrogen gas.
Emits toxic fumes under fire conditions.
Fire may produce irritating, corrosive and/or toxic gases.
Corrosive. Causes burns. Lachrymator. Vesicant.
Can cause irritation or burns of the esophogus or GI tract.
Can cause sever respiratory tract irritation can progress to ARDS/acute lung injury which may be delayed in onset for up to 24 to 72 hours in some cases. Burns of the esophagus are also possible.C
Consider gastric lavage after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in Trendelenburg and left lateral decubitus position or by endotracheal intubation. Control any seizures first. The use of activated charcole or dilution with milk or water may also be of benefit.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists.
Irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
