FXD

Autoignition: 725 F / 385 Cd

Extinguishing media:

Use Co2 or dry chemical for small fires, alcohol-type aqueous film-forming foam or water spray for large fires. Water may be ineffective but should be used to cool fire-exposed structures and vessels.

Special fire-fighting procedures:

Wear self-contained breathing apparatus (SCBA) and complete personal protective equipment when potential for exposure to vapors or products of combustion exists. Water spray can be used to reduce intensity of flames and to dilute spills to nonflammable mixture.

Unusual fire and explosion hazards:

Vapor is heavier than air and can travel considerable distance to a source of ignition and flashback. Material can burn with little or no visible flame. Methanol-water mixtures will burn unless very dilute. Mixtures with 25% or more Methanol are OSHA Class I Flammable Liquids.

Effects of exposure/toxicity data

Acute:

Ingestion (swallowing): Poisonous if swallowed. Can affect the optic nerve resulting in blindness. Can cause mental sluggishness, nausea and vomiting leading to severe illness, possible death (in humans). Practically non-toxic to animals (oral LD50, rats: 7.5 g/kg).

Inhalation (breathing): Extremely high levels cause stupor, headache, nausea, dizziness and unconsciousness. Prolonged periods of high levels has resulted in death. Liver damage has resulted from prolonged or repeated inhalation of vapors. Practically non-toxic to animals (inhalation LC50, rats, 4hrs:64,000 ppm).

Skin contact: Essentially non-irritating. Repeated or prolonged contact causes drying, brittleness, cracking and irritation. Slightly toxic to animals by absorption (dermal LD50, rabbits: 20 g/kg).

Eye contact: May cause eye injury which may persist for several days. Liquid, and vapor in high concentrations causes irritation, tearing and burning sensation.

Chronic:

Mutagenicity: In vitro, limited evidence of mutagenicity (mouse lymphoma forward mutation assay). In vivo, no information.

Carcinogenicity: No evidence of carcinogenic potential in limited animal studies in which methanol was given orally or applied to the skin.

Reproduction: Methanol - reported to cause birth defects in rats exposed to very high levels of vapors (20,000 ppm).

Emergency and first aid procedures

Ingestion (swallowing): Induce vomiting of conscious patient immediately giving two glasses of water and pressing finger down throat. Drink a large amount of water, milk or sodium bicarbonate to dilute material in stomach. Contact a physician immediately.

Inhalation (breathing): Remove patient from contaminated area. if breathing has stopped, give artificial respiration, then oxygen if needed. Contact a physician immediately.

Skin Contact: Remove contaminated clothing and wash contaminated skin with large amounts of water. If irritation persists, contact a physician.

Eye contact: Flush eyes with water for at least 15 minutes. Contact a physician immediately.

Note to physician: When plasma methanol concentrations are higher than 20 milligrams per deciliter, when ingested doses are greater than 30 milliliters, and when there is evidence of acidosis or visual abnormalities, a 10% solution of ethanol in 5% aqueous dextrose, administered intravenously, is a safe, effective antidote (Western Journal of Medicine, March 1985, p. 337).

Spill or leak procedures

Steps to be taken if material is released or spilled.

Eliminate ignition sources. Dike large spills. Avoid eye or skin contact. Place leaking containers in well-ventilated area. If fire potential exists, blanket spill with foam or use water spray to disperse vapors. Contain spill to minimize contaminated area and facilitate salvage or disposal. Comply with federal, state and local regulations on reporting releases.

Waste disposal method:

This product when spilled or disposed is a hazardous solid waste. Preferred method is incineration or biological treatment in federal/state approved facility.
