FED-STD-791D
c. Fire Precautions (In case of outbreak): Use large amounts of water to cool
containers and wash away spills.
Spills:
Cover with weak reducing agents such as hypo, bisulfites or ferrous salts.
Bisulfites or ferrous salts need additional promoter of some 3M-H2SO4 to
accelerate reaction. Transfer the slurry (or sludge) into a large container of
water and neutralize with soda ash. Drain into a sewer with abundant water.
010 n-Butyl Alcohol CH3(CH2)2CH2OH
Synonyms: 1-Butanol; n-Butanol.
Life Hazard: Moderately dangerous because of its low volatility; when heated to
decomposition it emits toxic fumes; it can react with oxidizing materials.
Flammability: Moderate fire risk. Flash point (open cup) 45.5C, (closed cup) 28.9C;
ignition temp 365C; flammable limits 1.4-11.2%. Less reactive; no
adverse reaction takes place on fire.
Handling & Storage:
Store in cool, unlighted place away from sources of ignition, and
from explosives, oxidizing materials, organic peroxides, poisons
and radioactive materials.
Preferably provide electrical
equipment with spark-resistant construction. Wear safety glasses
and rubber protective clothing.
Emergency Treatment and Measures:
a. Hygienic Precautions: Adequate ventilations.
b. First Aid: Flush eyes thoroughly with water. Wash out contaminated skin with
soap and water. If swallowed, call a physician.
c. Fire Precautions (In case of outbreak): Use dry chemical, or carbon dioxide:
alcohol foam may be ineffective. Water spray may help to keep containers cool, to
dilute leaked butanol, and to diffuse vapors.
Spills:
Absorb on paper. Evaporate on a glass or iron dish in hood. Burn the paper.
Large quantities should be burned in a solvent burner.
011 Butyric Acid CH3(CH2)2COOH
Synonyms: Butanic Acid, Butanoil Acid, Ethylacetic Acid, Propanecarbonic Acid.
Life Hazard: Inhalation causes irritation of mucous membranes and respiratory track;
may cause nausea and vomiting. Ingestion causes irritation of mouth and
stomach. Contact with eyes can cause serious injury. Contact with skin
may cause burns; chemical is readily absorbed through the skin and may
cause damage by this route.
