Fire-Fighting Measures

"Empty" Container Warning "Empty" containers retain residue (liquid and/or vapor) can be dangerous. DO NOT PRESSURIZE, CUT, WELD, BRAZE, SOLDER, DRILL, GRIND OR EXPOSE SUCH CONTAINERS TO HEAT, SPARKS, STATIC ELECTRICITY OR OTHER SOURCES OF IGNITION; THEY MAY EXPLODE AND CAUSE INJURY OR DEATH. Do not attempt to clean since residue is difficult to remove. "Empty" drums should be completely drained, properly bunged and promptly returned to a drum reconditioner. All other containers should be disposed of in an environmentally safe manner and in accordance with governmental regulations. For work on tanks refer to Occupational Safety and Health Administration regulations, ANSI Z49.1, and other governmental and industrial references pertaining to cleaning, repairing, welding, or other contemplated operations.
Extinguishing Media and Fire-Fighting Procedures Use water spray to cool fire exposed surfaces and to protect personnel. Shut off fuel to fire if possible to do so without hazard. If a leak or spill has not ignited use water spray to disperse the vapors. Do not extinguish flames at leak because possibility of uncontrolled explosive re-ignition exists. Cut off fuel and/or allow fire to burn out. Extinguish small residual fires with dry chemical powder or water spray. Try to cover liquid spills with foam.

NFPA - Hazard Class Health:1  Fire:4  Reactivity:0
HMIS Health:1  Fire:4  Reactivity:0
Decomposition Products Under Fire Conditions Smoke, carbon monoxide, carbon dioxide.
Handling Precautions / General Hazards Extremely flammable; material will readily ignite at ambient temperatures. Flammable Gas; may readily form flammable mixtures at or above the flash point. Toxic gases will form upon combustion. Static discharge; material can accumulate static charges which may cause an incendiary electrical discharge. 
Auto-refrigeration; drains may become plugged and valves may become inoperable because of the formation of ice due to expanding vapours or vapourizing liquids.
Special Precautions Respiratory and eye protection required for fire fighting personnel. A self-contained breathing apparatus (SCBA) should be used for all indoor fires and any significant outdoor fires. For small outdoor fires, which can easily be extinguished with a portable fire extinguisher, use of an SCBA may not be required.

Chemical Stability Stable
Incompatible Materials Strong oxidizing agents.

Health Hazard Information

Routes of Entry
Skin Contact Exposure to rapidly expanding gas or vapourizing liquid may cause frostbite (cold burns).
Eye Exposure to rapidly expanding gas or vapourizing liquid may cause frostbite (cold burns) and permanent eye damage.
Inhalation May cause central nervous system disorder (e.g. loss of coordination, weakness, fatigue, mental confusion and blurred vision) and/or damage. Breathing high vapour concentrations (saturated vapours) for a few minutes may be fatal. Saturated vapours can be encountered in confined spaces and/or under conditions of poor ventilation. May cause irritation, breathing failure, coma and death without any warning odour being sensed.
Ingestion Not considered to be a hazard.

Emergency and First Aid Procedures

Eyes In case of cold burns caused by rapidly expanding gas or vapourizing liquid, get prompt medical attention.
Skin In case of cold burns caused by rapidly expanding gas or vapourizing liquid, get prompt medical attention.
Inhalation If overcome by vapor, remove from exposure and call a physician immediately. If breathing is irregular or has stopped, start resuscitation, administer oxygen, if available.
Ingestion First Aid is not applicable.

Preventative Measures

Exposure Controls The use of local exhaust ventilation is recommended to control emissions near the source. Laboratory samples should be handled in a fumehood. Provide mechanical ventilation of confined spaces. Use explosion-proof ventilation equipment.
Personal Protection In open systems where contact is likely, wear gas-proof goggles, face shield, chemical resistant overalls, and appropriate thermal/chemical gloves. Where skin and eye contact is unlikely, but may occur as a result of short and/or periodic exposures, wear long sleeves, chemical resistant gloves, gas-proof goggles, and a face shield. Where concentrations in air may exceed the occupational exposure limits of exposure reduction are not adequate, approved respirators may be necessary to prevent overexposure by inhalation.
Note N/A

Environmental Procedures

Spills or Releases Land Spill: 
Eliminate source of ignition. Keep public away. Prevent additional discharge of material, if possible to do so without hazard. Vapours or dust may be harmful or fatal. Warn occupants of downwind areas. Allow to evaporate. Consult an expert on disposal of recovered material. Ensure disposal in compliance with government requirements and ensure conformity to local disposal regulations. Notify the appropriate authorities immediately. Take all additional action necessary to prevent and remedy the adverse effects of the spill.

Water Spill:
Eliminate all sources of ignition. Vapours or dust may be harmful or fatal. Warn occupants and shipping in downwind areas. Allow to evaporate from surface. Consult an expert on disposal of recovered material. Ensure disposal in compliance with government requirements and ensure conformity to local disposal regulations. Notify the appropriate authorities immediately. Take all additional action necessary to prevent and remedy the adverse effects of the spill.

Disposal Clean up action should be carefully planned and executed. Shipment, storage and/or disposal of waste materials are regulated and action to handle or dispose of spilled or released materials must meet all state, local, and federal rules.
Storage Keep containers closed. Handle and open containers with care. Store in a cool, well ventilated place away from incompatible materials. Store as pressurized liquid in a pressure vessel. Store and load the container at normal (up to 38 deg C) temperature and at atmospheric pressure. Material will accumulate static charges which may cause a spark. Static charge build-up could become an ignition source. Use proper grounding procedure. Imperial Oil has no knowledge how its customers will handle, store, transfer, distribute, or use odourized propane and therefore makes no warranty regarding the propane or ethyl mercaptan after the custody of these materials passes to the customers. It is recommended that Imperial Oil's customers provide their employees and subsequent customers with information regarding the characteristics of propane, how those characteristics relate to the employees or customers use inducing the limitation of any odourant including ethyl mercaptan. With proper handling, transportation and storage, adding a chemical odourant such as ethyl mercaptan has proven to be a very effective warning device, but all odourants have certain limitations. The effectiveness of the odourant may be diminished by a person's sense of smell, by competing odours and by oxidation which may cause a potentially dangerous situation. Further safety related information is contained on the Material Safety Data Sheet.
Industry experience has shown that natural gas streams may contain trace amounts of radon, a naturally occurring radioactive gas, and radioactive particulate decay products which can accumulate in process equipment and storage vessels. These materials emit gamma, alpha, and beta forms of radiation. Since gamma radiation can penetrate the walls of intact equipment a potential for exposure could exist at or adjacent to the external surface of process equipment that contain radon-enriched process streams or accumulated deposits of radon decay products. Equipment emitting gamma radiation at dose rates above background should be assumed to be contaminated with internal deposits of alpha-and-beta-emitting radon decay products. Measures should be taken to preclude the inhalation or ingestion of alpha-beta-emitting materials. Before performing maintenance on contaminated equipment, all process shut-down and the opening of equipment for repair operations. This time will allow the gamma radiation does rates to be reduced to background levels. Maintenance personnel should wear appropriate personal protective equipment and follow recommended industrial hygiene/safety and environmental procedures in accordance with prevailing regulations and industry guidelines.

ELECTROSTATIC ACCUMULATION HAZARD: Yes, use proper grounding procedures.
