Section 2: SAFETY
2.1
General. This chapter contains information that will aid facility personnel in
establishing an effective safety program. Safety is the responsibility of each individual,
regardless of position. Safety must be practiced daily in every maintenance activity that is
performed. Local operational procedures, and OSHA requirements should also be followed.
The safety program established at each facility should include preventive safety precautions, and
first-aid procedures for use in the event of an injury.
2.2
Causes of Accidents. Some common causes of accidents are:
a) Working on equipment without adequate coordination with equipment users.
b) Working on equipment without sufficient experience on that equipment.
c) Failure to following instructions in equipment manuals.
d) Failure to follow safety precautions.
e) Using unsafe equipment.
f) Failure to use safety devices.
g) Working at unsafe speeds.
h) Poor housekeeping of work areas.
2.3
Safety Procedures and Guidelines. Most lighted navigational aids are exposed to
weather and moisture and may develop electrical shock hazards through damage from lightning
or insulation deterioration from exposure. Maintenance procedures should begin only after a
visual inspection has been made for possible hazards. Due to the danger of lightning, lighted
navigational aids should not be serviced during periods of local thunderstorm activity. Develop
and implement a set of action plans to follow in the event of an accident occurring. A known set
of predetermined responses should be in place to ensure that positive responsive actions take
place within moments of accident notification. For example: on airfield frequencies, using the
phrase "man down... man down, we need assistance" over the radio to the tower personnel
would result in the tower placing a 911 call for medical assistance and dispatching the fire
department to the caller's location. Precious seconds are saved getting medical assistance to
those in need when action plans are in place. Action plans should be rehearsed and reviewed
regularly.
2.3.1
Two Basic Rules. A potential hazard exists whenever work is performed on or around
energized electrical equipment. The following basic rules should be followed by all personnel:
a) Work should never be performed on energized electrical conductors or
equipment, except for measuring voltage or current.
