GENERAL SAFETY INFORMATION

There are many hazards inherently present when performing any maintenance task on this
aircraft. To minimize the risk to both yourself and others, begin by thinking through each task
that is to be performed before starting any work. Using common sense, think of ways to avoid
these hazards. Remember also that many accidents happen because of carelessness. Be sure
to also use the right tool for the task at hand and to use the proper personal protective
equipment. Such equipment may include, but is not limited to:
Eye protection – safety glasses, goggles, and face shield

Gloves

Hearing protection – ear plugs or muffs

Apron

Protective footwear with non-slip soles

You should also keep on hand a suitable fire extinguisher, absorbent material to contain spills,
an eyewash bottle, and a general-purpose first aid kit. It is also advisable to have on hand the
material safety data sheet (MSDS) for all products and chemicals that will be used during the
servicing of the aircraft.
Some other general rules to follow are:
Never leave the ignition switch or the master switch turned on when the engine is not

running. Doing so could allow the engine to fire if the propeller were rotated by hand.
Never operate the engine with untrained personnel around – everyone who is essential

to be in the area should be reminded that a spinning propeller may be lethal yet almost
invisible. Remove hats when running the engine to keep them from being removed by
the propeller slipstream.
Remove any loose clothing, such as neckties and scarves. Tuck in your shirt and secure

any long hair to prevent them from becoming tangled in power tools.
Remove all jewelry. Not only can items such as rings, watches, and necklaces become

caught in rotating tools, they can also conduct electricity and may cause a short circuit.
This could result in burns or damage to electrical circuits.
Disconnect the negative lead from the battery when doing any electrical work that does

not involve troubleshooting the electrical systems. This will reduce the risk of a short
circuit or even a fire.
The lead acid battery will emit hydrogen gas when charging, which is highly flammable.

Any nearby source of ignition such as sparks or an open flame can result in an
explosion. Keep all ignition sources away from the battery.
Aviation gasoline is also highly flammable. When working with the fuel system, always

work in a well-ventilated environment. Any nearby source of ignition such as sparks or
an open flame can result in a fire or explosion. Keep all ignition sources away. Always
ground the airframe to a suitable earth ground during fueling/defueling operations to
reduce the risk of a static discharge ignition source.
When working with the landing gear, always support the aircraft properly with jacks. Do

not work underneath the aircraft unless it is properly supported.
