EXTINGUISHING MEDIA
Suitable: Use extinguishing media appropriate to surrounding
fire conditions. Quench with large quantities of water. Use
water spray to cool fire-exposed containers.
FIREFIGHTING
Protective Equipment: Wear self-contained breathing apparatus
and protective clothing to prevent contact with skin and eyes.
Specific Hazard(s): Contact with other material may cause fire.
May accelerate combustion. Emits toxic fumes under fire
conditions.
Specific Method(s) of Fire Fighting: Do not direct a solid
stream of water or foam into burning molten material; this may
cause spattering and spread the fire.
EXPOSURE HAZARD(S)
Material: Corrosive. Toxic. Oxidizer.
Combustion Products: Nitrogen oxides
Combustion Gases: May react with metals, releasing flammable
hydrogen gas.

Section 11 - Toxicological Information
ROUTE OF EXPOSURE
Skin Contact: Causes severe burns.
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: Causes severe burns.
Inhalation: Material is extremely destructive to the tissue of
the mucous membranes and upper respiratory tract. Highly toxic
by inhalation.
Ingestion: Toxic if swallowed.
SIGNS AND SYMPTOMS OF EXPOSURE
Material is extremely destructive to tissue of the mucous
membranes and upper respiratory tract, eyes, and skin.
Inhalation may result in spasm, inflammation and edema of the
larynxand bronchi, chemical pneumonitis, and pulmonary edema.
Symptoms of exposure may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea, and
vomiting. Large doses may cause: conversion of hemoglobin to
methemoglobin, producing cyanosis; marked fall in blood
pressure, leading to collapse, coma, and possibly death.
