Use DRY chemical, carbon dioxide, alcohol-resistant foam or water spray. Wear adequate personal protection to prevent
contact with material or its combustion products. Self contained breathing apparatus with a full facepiece operated in a pressure
demand or other positive pressure mode. Cool containing vessels with flooding quantities of water until well after fire is out.
When heated, flammable and toxic vapors emitted. Contact with oxidizers may cause fire and/or explosion. Emits toxic
fumes under fire conditions.
Section IV. Fire and Explosion Data
Effects of Acute
Exposure
Routes of entry Inhalation and ingestion. Eye contact. Skin contact. Skin absorption.
Ingestion
Inhalation
Skin
Eye Vapors causes tearing and severe irritation. Liquid causes severe burns. Eye contact can result in corneal damage or
blindness. IRRITATION: EYE-RABBIT 750 ug/24H SEVERE (FORMALDEHYDE).
Contact with liquid causes irritaion, drying, scaling, and cracking. Prolonged and repeated contact causes hardening or tanning
effect. May cause allergic dermatitis. Liquid can be absorbed in toxic amounts through intact skin (massive skin contact can
cause visual impairment and death). IRRITATION: SKIN-RABBIT 2 mg/24H SEVERE (FORMALDEHYDE).
Toxic. Vapors and mists are extremely irritating to the nose, throat, lungs and mucous membranes. Bronchitis,
bronchopneumonia, pulmonary edema and chemical pneumonitis may occur. Prolonged exposure may result in more
severe irritation and tissue damage. Methanol can cause central nervous system depression (signs and symptoms may
include headache, dizziness, nausea, vomiting, drowsiness and incoordination), coughing, chest pain and dyspnea. Can
affect the optic nerve resulting in blindness.
Toxic. Vapors, mists, and liquid are extremely irritating to the mouth and throat and stomach. Swallowing the liquid
inflames the tissues, causes severe abdominal pain, nausea, vomiting, hematuria, proteinuria, anuria, acidosis, and
possible loss of consciousness. Methanol can affect the optic nerve resulting in blindness.
Oxides of carbon (CO, CO2).
