WARNING PAGE
Personnel performing operations, procedures, and practices that are included or implied in this
technical manual shall observe the following warnings. Disregard of these warnings and
precautionary information can cause serious injury or loss of life.
NOISE LEVELS
Sound pressure levels in this aircraft during some operating conditions exceed the Surgeon
General's hearing conservation criteria, as defined in TB MED 501. Hearing protection devices,
such as a headset or ear plugs, shall be worn by all personnel in and around the aircraft during its
operation.
STARTING ENGINES
Operating procedures or practices defined in this technical manual must be followed correctly.
Failure to do so may result in personal injury or loss of life.
Exposure to exhaust gases shall be avoided since exhaust gases are an irritant to eyes, skin, and
respiratory system.
HIGH VOLTAGE
High voltage is a potential hazard around AC inverters, ignition exciter units, and strobe beacons.
USE OF FIRE EXTINGUISHERS IN CONFINED AREAS
Monobromotrifluoromethane (CF Br) is very volatile, but is not easily detected by its odor-
3
Although non toxic, it must be considered to be about the same as other refrigerants and carbon
dioxide, causing danger to personnel primarily by reduction of oxygen available for proper
breathing. During operation of the fire extinguisher, ventilate personnel areas with fresh air. The
liquid shall not be allowed to come into contact with the skin, as it may cause frostbite or low
temperature burns because of its very low boiling point
VERTIGO
The strobe beacon lights should be turned off during flight through clouds to prevent sensations
of vertigo, as a result of reflections of the light on the clouds.
