Section 2 – Safety Considerations and Precautions
Before installing and operating the MHCP Precleaner, it is important to review and understand the following safety information.
There are set-up, maintenance and operational activities involving both stationary and operating conveyors. Each case has a safety
protocol.
2.1 Stationary Conveyors
The following activities are performed on stationary conveyors:
• Installation • Blade replacement • Repairs
• Tension adjustments • Cleaning

It is imperative that OSHA/MSHA Lockout/Tagout (LOTO)
regulations, 29 CFR 1910.147, be followed before undertaking
the preceding activities. Failure to use LOTO exposes workers
to uncontrolled behavior of the belt cleaner caused by
movement of the conveyor belt. Severe injury or death can
result.
Before working:
• Lockout/Tagout the conveyor power source
• Disengage any takeups
• Clear the conveyor belt or clamp securely in place
Use Personal Protective Equipment (PPE):
• Safety eyewear
• Hardhats
• Safety footwear
Close quarters, springs and heavy components create a
worksite that compromises a worker’s eyes, feet and skull.
PPE must be worn to control the foreseeable hazards
associated with conveyor belt cleaners. Serious injuries
can be avoided.
2.2 Operating Conveyors
There are two routine tasks that must be performed while the conveyor is running:
• Inspection of the cleaning performance
• Dynamic troubleshooting
Every belt cleaner is an in-running nip hazard. Never
touch or prod an operating cleaner. Cleaner hazards cause
instantaneous amputation and entrapment.
Never adjust anything on an operating cleaner.
Unforseeable belt projections and tears can catch on
cleaners and cause violent movements of the cleaner
structure. Flailing hardware can cause serious injury
or death.
Belt cleaners can become projectile hazards. Stay as far from
the cleaner as practical and use safety eyewear and headgear.
Missiles can inflict serious injury.
