powder or granular form, mixed with air.
CHEMICAL DANGERS:Heating may cause violentcombustion or explosion. Reacts
violently with water producingflammable methanol andcorrosive sodium hydroxide. Thesubstance may ignitespontaneously on contact withmoist air. The substance is astrong reducing agent and reacts
violently with oxidants. Thesubstance is a strong base, itreacts violently with acid and iscorrosive. Attacks many metalsforming flammable/explosive
gas (hydrogen - see ICSC 0001).

EXPOSURE LIMITS:TLV not established.MAK not established.
quickly when dispersed
EFFECTS OF SHORT-TERM
EXPOSURE:The substance is corrosive to theeyes, the skin and the respiratorytract. Corrosive on ingestion.Inhalation of aerosol may causelung oedema (see Notes).Medical observation is indicated.
EFFECTS OF LONG-TERM
OR REPEATED EXPOSURE:
PHYSICALPROPERTIES
Melting point (decomposes):
127°CDensity: 1.3 g/cmSolubility in water: reaction
Auto-ignition temperature: 70-
80°CExplosive limits, vol% in air: 7.3- 36
ENVIRONMENTALDATA
N O T E S
Reacts violently with fire extinguishing agents such as water. The symptoms of lung oedema
often do not become manifest until a few hours have passed and they are aggravated by physicaleffort. Rest and medical observation are therefore essential. Immediate administration of anappropriate inhalation therapy by a doctor or a person authorized by him/her, should beconsidered. Rinse contaminated clothes (fire hazard) with plenty of water.
