Hazards and Protection.
Storage
In general, materials which are toxic as stored or which can decomp into toxic components.Should be stored in cool, well-ventilated place, out of direct rays of sun, away from areas of high fire hazard and should be periodically inspected and monitored.
B3 D2B
Handling
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.
Protection
If special chemical protective clothing is required, consult the chemical manufacturer or specific protective clothing compatibility charts.
Respirators
Wear positive-pressure SCBA and protective equipment.
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.

Stability
No data.
Incompatibilities
Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products.
Decomposition
When heated to decomposition it emits acrid smoke and irritating fumes.

Fire.
Flash Point,°C
58
Autoignition, °C
330
Fire fighting
Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.
Fire potential
Flammable liquid when exposed to heat or flame.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
Combustion products
Emits toxic fumes under fire conditions.

Exposure effects
   Ingestion
Drowsiness, unconsciousness. See inhalation.
   Inhalation
Acute effects - cough, sore throat. Irritates the eyes, skin and respiratory tract. May cause effects on the central nervous system. High levels, if ingested, could cause lowering of consciousness.
   Skin
Redness, dry skin. Defats the skin.
   Eyes
Redness, pain.

First aid
 
   Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
   Inhalation
Call for medical aid. Remove the victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
   Skin
Wash immediately with soap and water with copious amounts of water.
   Eyes
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.
