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
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.
