SAFETY PROCEDURES AND WARNINGS:
The following statements of warning apply all or in part to the procedures and information contained within
this document. Failure to observe these precautions may result in serious injury to those performing the work
and/or bystanders.
WARNING: When performing work and testing these devices and the associated brake details, the vehicle
on which the equipment is installed must be properly chocked and blue flagged to protect
against inadvertent vehicle movement which could result in injury to personnel present and/or
damage to equipment.
WARNING: The use of an air jet, which must be less than 30 psi, to blow parts clean or to blow them dry
after being cleaned will cause particles of dirt, contaminants and/or droplets of the cleaning
liquid to be air borne. These conditions may cause skin and/or eye irritation. Avoid direct
contact with this air stream or possible flying debris.
WARNING: When using an air jet do not direct it toward another person. Improper use of the jet could
result in bodily injury.
WARNING: Personal eye protection, must be worn when performing any work on the equipment and
associated details to avoid possible injury to eyes.
WARNING: When blowing out the brake pipe, and/or the opening and closing of air valves, make sure all
personnel are clear of the ends of the vehicle as well as under the vehicle to protect against
injury from flying debris as well as potential movement of brake rigging, cylinders, etc.
WARNING: When handling valve portions, care must be taken to prevent the portion from falling which
could result in portion damage and/or injury to personnel. Also protection of the open face of
the valve portion is required to protect against the entrance of contaminants which could result
in unsafe brake operation of the vehicle on which the portion is installed.
WARNING: Cast iron air brake portions are very heavy. Extreme care is essential when applying, removing
or lifting the complete control valve including the pipe bracket, service and emergency portions
to preclude personal injury. Adequate support or lifting mechanism is required.
