2 ?Hazards Identification
CAUTION! Contents under pressure. May be irritating to eyes, respiratory tract and skin.
Repeated skin contact may cause allergic skin reaction. Prolonged overexposure may cause
liver, blood, lymphatic system or central nervous system effects. Prolonged or repeated skin
exposure may cause drying, defatting and dermatitis. Use with adequate ventilation. Keep away
from heat, sparks and all other sources of ignition. Avoid eye contact and inhalation.
Symptoms of Overexposure:
Inhalation: Inhalation may cause nose, throat, and respiratory tract irritation, coughing,
headache, and anesthesia. Prolonged exposure to the propellant may cause rapid breathing,
headache and dizziness.
Skin Contact: May cause skin irritation. Prolonged contact may cause defatting, dermatitis, and
drying of the skin. May cause sensitization by skin contact.
Eye Contact: May cause eye irritation with redness, tearing and blurred vision.
Ingestion: May be harmful if swallowed. Ingestion may cause vomiting and headache. May
cause damage to liver and kidneys.
Chronic Effects: May cause blood disorders, liver, lymphatic system and ventral nervous system
effects based on animal data.
Medical Conditions Aggravated by Exposure: Preexisting skin conditions or allergies may be
aggravated by exposure.

Inhalation (Breathing): If irritation is experienced, move to fresh air. Get medical attention if
irritation or other symptoms develop and persist.
5 ?Fire Fighting Measures
Extinguishing Media: Use water fog, dry chemical, carbon dioxide or foam.
Special Fire Fighting Procedures: Firefighters should always wear positive pressure self-
contained breathing apparatus and full protective clothing. Cool fire-exposed containers with
water. Use shielding to protect from bursting cans.
Unusual Fire and Explosion Hazards: Contents under pressure. Keep away from ignition
source and open fire. Exposure of containers to extreme heat and flames can cause them to
rupture often with violent force. Vapors are heavier than air and may travel along the ground to
remote sources and flash back.
6 ?Accidental Release Measures
Immediately remove all sources of ignition. Remove personnel from general area. Wear
appropriate protective clothing (see Section 8). Contain and collect liquid with an inert absorbent
and place in a container for disposal. Clean spill area thoroughly. Report spills to authorities as
7 ?Handling and Storage
Handling: Avoid contact with eyes. Avoid prolonged contact with skin. Avoid breathing vapors or
aerosols. Use with adequate ventilation. Wash thoroughly with soap and water after handling.
Keep containers closed when not in use. Keep out of the reach of children.
Storage: Store in a cool, well-ventilated area, away from incompatible materials and heat, sparks
or open flame. Do not store in direct sunlight or above 120癋. U.F.C (NFPA 30B) Level 2
