3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
PHYSICAL APPEARANCE: Clear, Colorless, Volatile Liquid
IMMEDIATE CONCERNS: Warning! High concentrations of vapor can reduce oxygen available for breathing. Harmful if inhaled.
May decompose on contact with flames or extremely hot metal surfaces to produce toxic and corrosive products.
POTENTIAL HEALTH EFFECTS
EYES: Liquid contact can cause irritation, which may be severe.
SKIN: Prolonged or repeated contact can result in defatting and drying of the skin which may result in skin irritation and dermatitis
(rash).
INHALATION: High concentrations in immediate area can displace oxygen and can cause dizziness, unconsciousness, and possibly
death with longer exposure. Keep people away from such vapors without self-contained breathing apparatus.
SIGNS AND SYMPTOMS OF OVEREXPOSURE
EYES: Can cause severe eye irritation.
SKIN: Exposure to rapidly expanding gas or vaporizing liquid may cause frostbite ("cold" burn).
INHALATION: High concentrations may lead to central nervous system effects (drowsiness, dizziness, nausea, headaches, paralysis and
loss of consciousness).
ACUTE TOXICITY: Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac
arrhythmia may result.
4. FIRST AID MEASURES
EYES: Immediately flush eyes with plenty of water. Get medical attention, if irritation persists.
SKIN: In case of cold burns (frostbite) caused by rapidly expanding gas or vaporizing liquids, get medical attention promptly.
INGESTION: Ingestion is unlikely because of the physical properties and is not expected to be hazardous. Do not induce vomiting unless
instructed to do so by a physician.
INHALATION: Remove to fresh air. If not breathing, give artificial respiration or give oxygen by trained personnel. Seek immediate
medical attention.

NOTES TO PHYSICIAN: Because of the possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine, should be
used with special caution and only in situations of emergency life support. Treatment of overexposure should be directed at the control of
symptoms and the clinical conditions.
5. FIRE FIGHTING MEASURES

8. EXPOSURE CONTROLS / PERSONAL PROTECTION
EXPOSURE GUIDELINES:
OSHA HAZARDOUS COMPONENTS (29 CFR 1910.1200)
OSHA TABLE COMMENTS:
1. * (AEL)=Acceptable Exposure Limit as established by the manufacture
ENGINEERING CONTROLS: Local exhaust ventilation may be necessary to control any air contaminants to within their TLVs during the
use of this product.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: Wear safety glasses with side shields (or goggles) and a face shield.
SKIN: Skin contact with liquid may cause frostbite. General work clothing and gloves (leather) should provide adequate protection. If
prolonged contact with the liquid or gas is anticipated, insulated gloves constructed of PVA, neoprene or butyl rubber should be used.
Any contaminated clothing should be promptly removed and washed before reuse.
RESPIRATORY: A respiratory protection program that meets OSHA 1910.134 and ANSI Z88.2 requirements must be followed
whenever work
p
lace conditions warrant a res
p
irator's use.
