• Check for flat tires periodically during a shift. If
the truck has been operating on a "flat", the truck
must not be parked indoors until the tire cools. If
the tire must be changed, DO NOT stand in front
of the rim and locking ring when inflating a tire
mounted on the machine. Observers should not
be permitted in the area and should be kept
away from the side of such tires.
A tire and rim assembly may explode if subjected
to excessive heat. Personnel must move to a
remote or protected location if there is a fire near
the tire and wheel area or if the smell of burning
rubber or excessively hot brakes is evident.
If the truck must be approached, such as to fight
a fire, those personnel must do so only while fac-
ing the tread area of the tire (front or back),
unless protected by use of large heavy equip-
ment as a shield. Stay at least 50 ft. (15 m) from
the tread of the tire.
In the event of fire in the tire and wheel area
(including brake fires), stay away from the truck
for at least 8 hours or until the tire and wheel are
cool.
• Keep serviceable fire fighting equipment on
hand. Report used extinguishers for replacement
or refilling.
• Always apply the parking brake when the truck is
parked and unattended. DO NOT leave the truck
unattended while the engine is running.
• Park the truck a safe distance away from other
vehicles as determined by the supervisor.
• Stay alert at all times! In the event of an
emergency, be prepared to react quickly and
avoid accidents. If an emergency arises, know
where to get prompt assistance.
