Belt and Chain Drive Safety

MEICA Works › General › Belt and Chain Drive Safety

Presenter		Project
Location		Date

Belt and chain drives transmit power between shafts and are common in pumps, conveyors, and plant.
Moving belts and chains create entanglement, drawing-in, and trapping hazards.
PUWER 1998 requires that dangerous parts of machinery are guarded to prevent contact.
Guards must be fixed or interlocked so the drive stops if the guard is opened.
Loose clothing, gloves, hair, and lanyards can be caught in unguarded drives.
Belt drives can throw a broken belt at high speed, causing serious impact injuries.
Chain drives can snag fingers and hands into sprockets within a fraction of a second.
Maintenance and adjustment of drives must only be done after isolation and lock-off.
Regular inspection detects wear, misalignment, and tension problems before failure occurs.
Incidents involving belt and chain drives are often severe, resulting in amputation or death.

Prevent entanglement	Moving belts and chains can draw a person in faster than they can react, causing amputation or fatal injuries.
Legal requirement	PUWER 1998 requires employers to ensure dangerous machinery parts are effectively guarded.
Reliability	Proper inspection and maintenance prevents unexpected breakdowns that can cause uncontrolled energy release.

Don't

Ensure all belt and chain drives are fitted with secure fixed or interlocked guards
Isolate and lock off the drive before any maintenance or adjustment work
Inspect belts and chains regularly for wear, tension, and alignment
Replace worn or damaged belts, chains, and sprockets promptly
Report any missing, damaged, or poorly fitted guards immediately
Tie back long hair and remove loose clothing before working near drives
Follow the permit to work procedure for maintenance on guarded machinery
Confirm the guard is securely refitted and interlocks function after maintenance
Train all operatives on the hazards of rotating machinery before they work nearby
Keep the area around belt and chain drives clean and free from obstructions
