All first aid procedures should be periodically reviewed by a doctor familiar with the chemical and its conditions of use in the workplace. Can easily ignite. Can readily form explosive mixture with air at room temperature.
Suitable Extinguishing Media: Dry chemical powder and high-expansion foam. Foam manufacturers should be consulted for recommendations regarding types of foams and application rates. Specific Hazards Arising from the Chemical: Gas or vapour may travel a considerable distance to a source of ignition and flash back to a leak or open container. Gas or vapour may accumulate in hazardous amounts in low-lying areas especially inside confined spaces, resulting in a health hazard.
Can displace oxygen in the air, causing suffocation. Direct addition of water to liquefied gas will cause flash vapourization resulting in an explosion either immediately or delayed known as a "boiling liquid, expanding vapour explosion BLEVE ". Heat from fire can cause a rapid build-up of pressure inside cylinders.
Explosive rupture and a sudden release of large amounts of gas may result. Cylinder may rocket. In a fire, the following hazardous materials may be generated: very toxic carbon monoxide, carbon dioxide.
Personal Precautions: Evacuate the area immediately. Isolate the hazard area. Keep out unnecessary and unprotected personnel. Evacuate downwind locations. Eliminate all ignition sources. Use grounded, explosion-proof equipment.
Monitor area for flammable or explosive atmosphere. Before entry, especially into confined areas, check atmosphere with an appropriate monitor. Test for sufficient oxygen levels. Methods for Containment and Clean-up: If possible, turn leaking container so that gas escapes rather than liquefied gas. Other Information: Contact supplier, local fire and emergency services for help. Report spills to local health, safety and environmental authorities, as required.
Handling: Eliminate heat and ignition sources such as sparks, open flames, hot surfaces and static discharge. Post "No Smoking" signs. Only use where there is adequate ventilation. Immediately report leaks, spills or failures of the safety equipment e. In the event of a spill or leak, exit the area immediately. Never work on pressurized system. Use piping and equipment designed for high pressures and cold temperatures. Propane poisoning. Symptoms depend on the type of contact, but may include: Burning sensation Convulsions Cough Diarrhea Dizziness Fever General weakness Headache Heartbeat -- irregular Heartbeat -- rapid Lightheadedness Loss of consciousness coma, or unresponsiveness Nausea and vomiting Nervousness Pain and numbness in arms and legs Skin irritation Slow and shallow breathing Weakness Touching liquid propane results in frostbite -like symptoms.
If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes. Before Calling Emergency. The following information is helpful for emergency assistance: Person's age, weight, and condition Name of the product ingredients and strengths, if known Time it was swallowed Amount swallowed However, DO NOT delay calling for help if this information is not immediately available.
What to Expect at the Emergency Room. The person may receive: Airway support, including oxygen, breathing tube through the mouth intubation , and breathing machine ventilator Blood and urine tests Chest x-ray ECG electrocardiogram, or heart tracing Fluids through a vein intravenous or IV Medicines to treat symptoms. Outlook Prognosis. Health Topics A-Z Read more. Easy-to-Read Materials Read more. You need to be aware that exposure to LPG is dangerous. When working with LPG, it is vital you know:.
If an LP gas cylinder has not been tested for 10 years or more, it should not be connected to an appliance. The cylinder should be tagged as defective. Under no circumstances should any attempt be made to modify a gas cylinder. LP gas is widely used by trades as a fuel for portable heating equipment, as well as by the public for barbecues and for camping.
Explosions and fires have occurred when cylinders of LP Gas propane or acetylene have been carried or left in closed vehicles such as vans or cars.
LPG cylinders must be transported in the upright position and appropriately secured for transport. Refillable LPG cylinders for gas appliances such as barbecues and heaters must only be filled if they have a current, legible test mark of a certified gas cylinder test station.
Periodic inspection intervals for retesting of welded cylinders less than kg water capacity filled with LPG typically connected to barbecues is 10 years. Gas cylinder filling stations are only allowed to fill cylinders that have a current, legible test mark of a certified gas cylinder test station. If a gas filling station, as part of a cylinder exchange, accepts any cylinder that is not appropriately marked, they will have to either:.
Avoid actions that may start burning by sparking since a combustible gas mixture will form. Remove installations that may cause spark. Do not electric switch buttons. Ensure air circulation in the environment and immediately evacuate the personnel in the environment without causing panic or rush.
Contact the fire department and the company concerned, if possible. In case of leakage through tubes, you must act very carefully knowing that large amounts of gas will form and this gas will be heavier than air. Avoid all kinds of action that will start burning by sparking. Should there be suitable mechanism, try to disperse LPG in gaseous state with water spray. Since LPG vapor can accumulate in closed places, cover sinks, waste water installations and sewage connections.
If the leakage has formed in closed areas such as room or kitchen, ensure air circulation by opening doors and windows and ventilate the environment for long time. Do not enter environments containing intense LPG vapor for purposes other than rescue or leakage stopping.
In unavoidable circumstances, trained personnel must perform rescue operation by wearing protective clothing and breathing apparatus. Steel body of the bottle must not be contacted with high temperature for long time for explosion. The best example for that is poisoning originating from geyser. All bottles manufactured after have to have TSE brand. Bottles must not be exposed to direct sun light.
Tubes must not be placed near heat producing devices such as radiator and stove. Do not place easily flammable materials near devices using LPG. Bottles must be kept vertical and in no way be tilted during use. Bottles must be kept at level lower than devices such as cookers and geysers. Bottles must not be stored in places such as basements, where air current cannot be provided. Hose must be jointless and patch-free and must not exceed cm.
Connection hose must be checked in regular intervals. Worn, cracked, softened or hardened hoses must be replaced immediately. Connection hose has its manufacture date written on it. This date must be checked and the hose must be replaced if it has completed 3 years.
Gas flow stopping type hoods must be used when required in order to prevent high flow leakages that may occur in connection hose or LPG using devices. Do not use flaming objects such as match or lighter. The environment they are used in must be ventilated well and must have volume greater than 8 m3.
