SAFETY SUMMARY
SIGNAL WORD DEFINITION
Per the ANSI Z535.4 standard, the following signal words and definitions are used to indicate hazardous
situations:
DANGER indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation that, if not avoided, could result in death or serious
injury.
CAUTION indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate
injury. It is also used to alert against unsafe practices.
GENERAL SAFETY PRECAUTIONS
The following are general safety precautions that are not related to any specific procedures and therefore do
not appear elsewhere in this publication. These are recommended precautions that personnel must
understand and apply during many phases of operation and maintenance.
Electrocution Hazard! Contact with high voltage will result in death or serious injury. Observe general
safety precautions for handling equipment using high voltage. Do not locate or operate mast near electrical
lines, cables or other unwanted sources of electricity. Do not operate mast in lightning. Be certain electrical
cables are undamaged and properly terminated. Always disconnect power before performing service, repair
or test operations.
Safety Instruction - Read Manual! Failure to follow operating instructions could result in death or serious
injury. Read and understand the operator’s manual before using the mast.
Tip Over Hazard! Mast tip over could result in death or serious injury. Do not operate in high winds.
Operate on level ground only. Stand clear of mast and mast payload during operation. Be certain mast is
level and secure before and during installation, operation and maintenance.
Safety Instruction - Trained Personnel Only! Death or serious injury could result if proper inspection,
installation, operation and maintenance procedures are not observed. Installation, operation and
maintenance to be performed by trained and authorized personnel only. Proper eye protection should be
worn when servicing the mast.
Health and Safety Hazard! Solvent used to clean parts is potentially dangerous. Avoid inhalation of fumes
and also prolonged contact to skin.
Safety Instruction-Do not look at lights! Do not look directly into lights when they are illuminated.
Temporary impairment or permanent vision damage could occur.

SPECIFIC SAFETY PRECAUTIONS
The following are safety precautions that are related to specific procedures and therefore appear elsewhere in
this publication for emphasis. These are recommended precautions that personnel must understand and
apply during specific phases of installation, operation and maintenance.
Safety Instruction-Operation! For outdoor use only. Do not use in areas that have been classified as
hazardous as defined in Article 500 of the National Electric Code.
Crush Hazard! Death or serious injury could result if mast fails suddenly. Do not stand directly beneath the
mast or its payload. Be certain payload is properly installed and secured.
Burst Hazard! Over pressurizing mast will trip safety valve and could result in death or serious injury. Do not
exceed maximum operating pressure of 20 psi (138 kPa) for Standard Duty masts. Keep personnel clear of
safety valve exhaust direction.
Fire Hazard! Cleaning solvent, used for maintenance, is flammable and can be explosive resulting in death
or serious injury. Do not smoke. Use cleaning solvent in a well-ventilated area. Keep cleaning solvent away
from ignition sources. Always store cleaning solvent in the proper marked container.
Relocation Hazard! Relocating the mast during operation or after extension could result in death or serious
injury. Do not relocate the mast during operation or while extended. This applies especially to masts
mounted to vehicles. Operate the mast only if the vehicle is stationary and the vehicle engine is off.
Mast Extension Hazard! Extending mast into obstructions could result in death or serious injury and could
render the mast inoperable and partially extended. Before applying power and operating the mast, be certain
there is sufficient clearance above and to all sides of the expected location of the fully extended mast and
payload. Keep all persons clear of mast and mast extension. Do not lean directly over the mast.
Mounting Structure Hazard! Mounting mast into a structure unable to resist the forces generated from
customer-specific loading scenario could result in death or serious injury and could damage the mast. Before
operation, be certain mounting structure is capable of resisting forces generated from all loading and
environmental conditions, including, but not limited to, mast size and weight, payload size and weight, sail
size, wind speed, guy line arrangement, support bracket or roof line location and base plate assembly.
Electrocution Hazard! Do not touch live wires. Death or serious injury could result.
Safety Instruction – Operation! Make sure all power has been disconnected prior performing maintenance.

Revision 1 iii
Safety Instruction -Trained Personnel Only! Only trained and qualified personnel should perform
installation, adjustments, and servicing. Only a properly trained and qualified certified electrician should
perform electric installations and service.
When relamping an installed fixture, make sure all power to fixture is off and that the fixture is cool
Safety Instruction – Operation! At all times prior to mast operation, insure that:
1.) The mast area is free of personnel and mechanical obstruction;
2.) All electrical cables are undamaged and properly terminated;
3.) The operator must have full view of the mast during use;
4.) Any transit tie-downs on the payload have been removed;
5.) The vehicle is not moving;
6.) The area above the mast is free of mechanical obstructions.
Safety Instruction-Operation! Lamps are extremely hot and should not come into contact with people or
combustible and/or explosive materials. Do not operate if breakage occurs or unit is knocked over.
Entanglement Hazard! Tangled cables can cause equipment damage. Ensure control cables are not
tangled and are free to pay out as mast is extended.
Safety Instruction – Installation! At all times while using pipe and hose during installation, recognize that:
1.) Pipe and hose should be routed, mounted and restrained to protect from damage;
2.) Do not use second hand piping for installation;
3.) Do not bend air pipe and hose at a radius less than specified by the manufacturer;
4.) Pipes should be marked to avoid hazards from incorrect connection;
5.) The exhaust should be fitted with a silencer and be directed away from personnel;
6.) When routing piping, install in such a way as to minimize torsion on the joints;
7.) Mounting air pipe and hose shall be accomplished only by the use of tools to prevent readily
disconnecting air pipe and hose from mast.
Safety Instruction – Operation! Do not operate the Chief vertical RCP during an electrical storm.
Lifting Hazard! Manually lifting over 55 lb (25kg) is prohibited. In the UK, all lifting equipment must be
thoroughly examined annually by a competent person according to the Lifting Operations and Lift Equipment
Regulations 1998. Equivalent regulations exist in other EU states.
Safety Instruction – Operation! All operators must read the Operation section of this manual and be
properly trained.
