SECTION II-Hazardous Identification
Emergency OverviewDANGER
Flammable gas. Contents under pressure. Containers may explode when heated.
Potential short term health effects
Routes of exposureEye, Skin contact, Inhalation.
EyesContact with liquid may cause frostbite.
SkinContact with liquid may cause frostbite.
Inhalation Excessive intentional inhalation may cause respiratory tract irritation and central Nervous system effects (headache, dizziness). Vapors may cause dizziness or suffocation.
IngestionNot a normal route of exposure.
Target organsEyes. Skin. Respiratory system.
Chronic effectsProlonged or repeated exposure can cause drying, defatting and dermatitis.
Signs and symptomsSymptoms may include redness, dryness of the skin.
Odor, Color, GradeClear, colorless with slight ethereal odor.
General Physical FormGas
Immediate health, physical, and environmental hazards:
  Closed containers exposed to heat from fire may build pressure and explode. May cause frostbite. May cause target organ effects.
SECTION III-Composition on Ingredients
ComponentCAS # 75-37-6    % by Wt    100% 1, 1-DIFLUOROETHANE
SECTION IV-First Aid Measures
Skin: Flush with cool water. Wash affected area with soap and water. If signs/symptoms persist, get medical attention.
Eye contact:Immediately flush with large amounts of cool water. Remove contact lenses, if applicable, and continue flushing for 15 minutes. Obtain medical attention immediately.
Inhalation: If symptoms develop, move victim to fresh air. If symptoms persist, obtain medical attention. If breathing has stopped, trained personnel should administer CPR immediately.
Ingestion: Do not induce vomiting. Never give anything by mouth if victim is unconscious, or is convulsing. Obtain medical attention.
SECTION V-Firefighting Measures
Flammable PropertiesFlammable by WHMIS/OSHA criteria. Containers may explode when heated. Autoignition temperature 849 °F
Flash Point: < 50 °F (Details: consumer aerosol does not exhibit a flame projection, therefore it is not determined to be flammble as defined in 16 CFR, Section 1500.3(c) (6) (viii).
Flammable Limits-LEL3.9% volume
Flammable Limits-UEL16.9% volume
Extinguishing media
Suitable extinguishing mediaSmall Fires: Dry chemical. Carbon dioxide. Water spray. Fog.
Unsuitable extinguishing media:Not available
Protection of firefighters specific hazards arising
from the chemical Contents under pressure. Pressurized container may explode when exposed to heat or flame. Cool containers with flooding quantities of water until well after fire is out.
Protective equipment for firefightersFirefighters should wear full protective clothing including self contained breathing apparatus.
Hazardous combustionproductsMay include and are not limited to: Oxides of carbon. Fluoride gases.

SECTION VI-Accidental Release Measures
Accidental Release MeasuresRefer to other sections of this MSDS for information regarding physical and health hazard, respiratory protection, ventilation, and personal protective equipment. Evacuate unprotected and untrained personnel from hazard area. The spill should be cleaned up by qualified personnel. Remove all ignition sources such as flames, smoking materials, and electrical spark sources. Use only non-sparking tools. Ventilate the area with fresh air. Close cylinder. If the cylinder can’t be closed, place in a well-ventilated area, preferably an operating exhaust hood, or if necessary outdoors. Dispose of collected material as soon as possible.
Personal precautionskeep unnecessary personnel away. Do not touch or walk through spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep people away from and upwind of spill/leak.
Methods for containmentEliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Stop leak if you can do so without risk. Prevent entry into waterways, sewers, basements or confined areas.
Methods for cleaning upBefore attempting clean up, refer to hazard data given above. Remove sources of ignition. Although the chance of a significant spill or leak is unlikely in aerosol containers, in the event of such an occurrence, absorb spilled material with a non-flammable absorbent such as sand or vermiculite.

SECTION VIII-Exposure Controls/Personal Protection
Engineering Controls: Do not use in a confined area or areas with little or no air movement.
Use general dilution ventilation and/or control mist, vapor, or spray.
If ventilation is not adequate, use respiratory protection equipment
Personal protective equipment
Respiratory protection: Do not breathe vapors. Use with adequate ventilation. Keep container closed.
For emergencies select one of the following NIOSH approved respirators based on airborne concentration of
contaminants and in accordance with OSHA regulations:
Half face piece or full face pressure demand self-contained breathing apparatus.
Hand protection:If there is constant skin contact, rubber gloves are recommended.
Eye/Face protection: Avoid eye contact with vapors, mists, or spray.
The following eye protection(s) are recommended: Safety Glasses with side shields.
Skin protection:Wear insulated gloves to protect against frostbite.
General hygiene considerations: Handle in accordance with good industrial hygiene and safety practice.
When using do not eat or drink.
Wash hands and face before breaks and immediately after handling product.
