Safety & Hazard Warnings

For general safety practices for air moving equipment, see AMCA Bulletin 410. Twin City Fan & Blower offers many safety
accessories. These safety devices include (but are not limited to) belt guards, shaft guards, inlet and discharge screens. The use
and suitability of safety devices is the responsibility of the purchaser.

Facility related safety conditions include fans’ accessibility and location. How easily can non-service personnel access the unit? Is
the fan in a hazardous duty environment? Was the unit ordered for this duty? Other concerns must also be addressed. All fans
should be powered through controls that are easily accessible to service personnel from the fan. Fan power must have the ability
to be “locked out” by service personnel trained in lockout/tagout procedures per OSHA requirements (29CFR1910.147). When
performing lockout, be aware of factors, such as building pressure and additional fans in the system that can influence unwanted
fan rotation (wind milling). If you have any doubt about your ability to perform a task, seek a person qualified to do that task.
Before any work is done on a fan, ensure that the fan is isolated from the electrical supply using a 'lockout/tagout system.'

Note: A stationary, non-rotating fan does not mean that the fan is isolated from the electrical supply or from other fans/dampers
in the system that could cause the fan wheel to rotate. A non-rotating fan could be subject to controls or other circuit protection
devices that may start the fan without notice.

The following safety precautions should be followed, where applicable:
• Do not attempt to slow a rotating wheel even when it is isolated from the electrical supply. Fan impellers have a high inertia

and injury could result from an attempt to stop it. It is recommended that the impeller is isolated by closing off the inlet or
outlet to prevent wind-driven rotation. If an wheel is chocked to prevent rotation, ensure that the chocks are removed prior
to start up.

• Wear appropriate personal protective equipment. This may include protective clothing, eye protection, ear protection,

respiratory equipment, hand and foot protection when installing or servicing the fan.

• Always use caution when entering a fan's air path. High velocity airflow can cause you to lose your balance.
• Motor, bearings and drives can be hot, and similarly if the fan is subject to processes that are hot, the fan housing could be

hot.

• Fans are often used to move hazardous materials that could be dangerous. Always wear protective clothing and take

precautions not to inhale dust/gases. If hazardous chemical vapors are present, respiratory equipment may be required.

•  Sharp edges – wear protective gloves when handling, installing or servicing a fan.
•  Fans can operate at high decibel sound levels. Wear proper ear protection to protect from excessive noise levels.
•  Access doors – Do not open access doors when fan is in operation. The effects of suction and air pressure could result in injury.
•  When working around pulleys and belts, keep hands away from pinch points. This pertains to when the fan is under or off

power.

Throughout this manual, there are a number of HAZARD WARNINGS that must be read and adhered to in order to prevent
possible personal injury and/or damage to equipment. Two signal words "WARNING" and "CAUTION" are used to indicate the
severity of a hazard and are preceded by the safety alert symbol. It is the responsibility of all personnel involved in installation,
operation and maintenance to fully understand the warning and caution procedures by which hazards are to be avoided.
