In last month’s column I mentioned protecting yourself from accidents and exposure to the chemicals we use. This month I will continue with shop safety reminders.
Each year, there seems to be at least one garage fire started by someone handling gasoline. This brings up two points, one being the safe handling of flammable liquids and what to do in the case of a fire.
Some reminders about gasoline: It is the gas or fumes that actually ignite. These fumes are heavier than air and settle to the floor. Working in an unventilated area, these fumes can reach the proper fuel/air ratio for ignition. The source of ignition is usually a spark from static electricity or an electrical appliance.
Nylon and wool clothing can produce static discharge. Try taking off a wool sweater or nylon shirt in the dark, there can be an interesting light show. Grounding the containers you are working with will help reduce the risk. That means providing a path for the electrical charge so that it does not build up and arc. This can be done by clipping a wire between two containers. With our dry atmosphere static is definitely a hazard. Use only safety lights rated for use in explosive atmospheres when handling gasoline. Dropping an ordinary light will cause it to break and produce a spark which will ignite the fuel.
Knowing what to do in case of a fire is equally important. Having the right fire extinguisher HANDY, and knowing how to use it, is a necessary shop skill. A good capacity A-B-C rated extinguisher should take care of most situations. Remember to point the extinguisher at the base of the flame. In the case of a burning liquid make very sure not to leave a “hot spot” as this will re-ignite the liquid immediately!
To learn more about handling fire extinguishers and fire safety, visit your local fire station and ask a professional. Most will be willing to offer advice. It could save them a call.
Keeping safe makes the hobby and life a lot more enjoyable!
