This week’s Toolbox Talk focuses on working around propane gas and the harmful affects of carbon monoxide. Whether you are at work, home or maybe even doing some ice-fishing, you potentially may be exposed to hazards from a gas leak, propane heaters, or carbon monoxide poisoning. Today, we look at what you should do if you smell gas or suspect a gas leak or have to deal with carbon monoxide hazards.
First, understanding what exactly propane gas is, can be helpful in knowing some of the hazards it may cause. Propane (also called LGP – liquefied petroleum gas or LP gas) is a liquid fuel stored under pressure. In most systems, propane is vaporized to a gas before it leaves the tank. Propane is flammable when mixed with air (oxygen) and can be ignited by many sources, including open flames, smoking materials, electrical sparks and static electricity. Severe “freeze burn” or frostbite can result if propane liquid comes in contact with your skin.
So, what should you so if you smell gas or suspect a gas leak?
First, immediately put out all smoking material and other open flames. Do not operate lights, appliances, telephones or cellphones. Any flames or sparks from theses sources can trigger an explosion or a fire.
Second, leave the area immediately. Get everyone out of the building or area where you suspect gas is leaking. If you can, turn off the main gas supply valve on your propane tanks if it is safe to so do.
Third, once you are away from the gas leak, call 911 or notify the local fire department. Do not return to the building until the all clear is given and a qualified professional determines it is safe to return.
Another safety hazard you may experience is carbon monoxide poisoning. What is carbon monoxide (CO)? You cannot taste or smell carbon monoxide, but it is a very dangerous gas, produced when any fuel burns. High levels of carbon monoxide can come from appliances that are not operating correctly, or from a venting systems or exhaust chimney that becomes blocked.
High levels of carbon monoxide can make you dizzy or sick. In extreme cases, it can cause brain damage or even death. If you or a co-worker shows physical symptoms of carbon monoxide poisoning, get out of the building and call 911 or the local fire department. Open windows to allow entry of fresh air and turn off any heaters or equipment that may be emitting fumes or carbon monoxide.
Being aware of your surroundings include being able to detect or smell unusual odors that could potentially save you or your co-workers life.
