SAFETY CONSIDERATIONS

Air-handling equipment is designed to provide safe and reli-

able service when operated within design specifications. To

avoid injury to personnel and damage to equipment or property

when operating this equipment, use good judgment and follow

safe practices as outlined below.

 

DANGER

NEVER enter an enclosed fan cabinet or reach into a unit

while the fan is running.
LOCK OPEN AND TAG the fan motor power disconnect

switch before working on a fan. Take fuses with you and

note removal on tag. Electric shock can cause personal

injury or death.
LOCK OPEN AND TAG the electric heat coil power dis-

connect switch before working on or near heaters.
Failure to follow these warnings could lead to personal

injury or death.

WARNING

CHECK the assembly and component weights to be

sure that the rigging equipment can handle them safely.

Note also, the centers of gravity and any specific rigging

instructions.
CHECK for adequate ventilation so that fumes will not

migrate through ductwork to occupied spaces when weld-

ing or cutting inside air-handling unit cabinet or plenum.
WHEN STEAM CLEANING COILS be sure that the area

is clear of personnel.
DO NOT attempt to handle access covers and removable

panels on outdoor units when winds are strong or gusting

until you have sufficient help to control them. Make sure

panels are properly secured while repairs are being made to

a unit.
DO NOT remove access panel fasteners until fan is com-

pletely stopped. Pressure developed by a moving fan can

cause excessive force against the panel which can injure

personnel.
DO NOT work on dampers until their operators are

disconnected.
BE SURE that fans are properly grounded before working

on them.
Failure to follow these warnings could result in personal

injury or equipment damage.

CAUTION

SECURE drive sheaves with a rope or strap before work-

ing on a fan to ensure that rotor cannot free-wheel.
DO NOT restore power to unit until all temporary walk-

ways inside components have been removed.
NEVER pressurize equipment in excess of specified test

pressures.
PROTECT adjacent flammable material when welding or

flame cutting. Use sheet metal or asbestos cloth to contain

sparks. Have a fire extinguisher at hand and ready for

immediate use.
Failure to follow these warnings could result in personal

injury or equipment damage.
