Conveyor systems play a vital role in manufacturing, warehousing, and material handling industries worldwide. They keep operations running smoothly by moving goods efficiently and continuously. However, these essential machines also present significant safety hazards-most notably, pinch points.
These are areas where parts of the conveyor system move close together, creating the potential to trap or crush fingers, hands, or other body parts. Without proper protection, pinch points can cause severe injuries, including amputations and fatalities.
In this blog post, we’ll dive deep into what conveyor pinch points are, why guarding them is critical, and how industry-leading solutions like those from Belt Conveyor Guarding (BCG) can help you create a safer workplace.
What Are Conveyor Pinch Points?
A pinch point occurs where two parts move toward each other or where a moving part moves past a stationary object, creating a narrow gap. On conveyors, these points typically exist around:
- Drive pulleys: The powered wheels that move the conveyor belt.
- Tail pulleys: The pulleys at the opposite end of the drive.
- Return rollers: Rollers beneath the conveyor belt that support the returning belt.
- Belt take-up areas: Where tension is applied to keep the belt tight.
- Return idler rollers: Rollers that support the belt along its length.
Workers can easily get caught in these areas if guards are missing or inadequate, especially during maintenance or cleaning operations.
Why Are Conveyor Guards Essential?
Conveyor guards serve as a physical barrier between workers and dangerous moving parts. Their importance cannot be overstated:
- Preventing Injuries: Guards stop hands, fingers, and clothing from getting caught, preventing crush injuries, amputations, and fatalities.
- Regulatory Compliance: OSHA (Occupational Safety and Health Administration) and MSHA (Mine Safety and Health Administration) require guarding of hazardous machine parts, including conveyor pinch points.
- Reducing Downtime: Injuries cause operational disruptions, investigations, and potential fines. Proper guarding helps keep production running smoothly.
- Promoting a Safety Culture: Visible, effective guarding demonstrates a company’s commitment to worker safety, boosting morale and productivity.
Statistics show that many conveyor-related injuries occur due to unguarded or poorly guarded pinch points, emphasizing the need for effective solutions.
Types of Conveyor Pinch Point Guards
There are several types of guards designed to protect workers from conveyor pinch points:
1. Flat Guards
Flat guards are versatile panels that cover pinch points and rotating parts. They allow for easy inspection and maintenance while providing a secure barrier.
2. Return Idler Guards
Return idler rollers, located under the conveyor belt, create hidden pinch points that are often overlooked. Return idler guards prevent accidental contact in these areas, especially where walkways or catwalks are nearby.
3. Barrier Guards
When fixed guards aren’t practical, fencing and gated barriers create safe zones around conveyors. Gates should be interlocked to stop the conveyor when opened, preventing access during operation.
Best Practices for Effective Conveyor Pinch Point Guarding
To maximize safety around conveyors, consider these best practices:
- Conduct Comprehensive Hazard Assessments: Identify all potential pinch points, including less obvious areas like return rollers and belt take-ups.
- Select the Right Guarding Solutions: Use fixed guards where possible, supplemented by flat guards, barriers, and handrails as needed.
- Regularly Inspect and Maintain Guards: Damaged or missing guards negate their protective purpose. Establish routine inspections and maintenance schedules.
- Train Employees Thoroughly: Workers should understand the dangers of pinch points and the importance of never bypassing or removing guards.
- Engage Safety Experts: Partner with experienced providers like BCG to design and implement customized guarding solutions tailored to your facility’s needs.
