to read and understand ALL safety instructions, safety decals, and manuals and
follow them when assembling, operating, or maintaining the equipment.
• Owners must give instructions and review the information initially and annually with all personnel before

2.3. Fan Safety
• Keep away from fan impeller/blade; high suction can pull a
person toward the inlet. Contact with an unguarded
impeller/blade will cause severe injury.
• Keep the inlet screen in place at all times.
• Remove foreign material from the fan inlet before operating.
• Do not operate the fan if there is excessive vibration or noise.
• When the power is locked out, fans can still be dangerous
because of potential “windmilling.” Always block the
impeller/blade before working on any moving parts.
2.4. Guards Safety
• Keep guards in place. Do not operate with guard removed.
• Do not walk on, step on, or damage guards.
• Lock out power before removing a guard.
• Ensure all guards are replaced after performing maintenance.
2.5. Lockout/Tagout Safety
Lockout/Tagout equipment before set-up, service, maintenance, and repair. Make sure to follow lockout and
tagout procedure in the Electric Motor Safety Section to prevent inadvertent start-up and hazardous energy
release.
