What is required for every accessible area of a conveyor installation?

• A. All head and tail pulleys must be guarded
• B. Every accessible area must have a pull cord
• C. A belt slip detection device is necessary
• D. Mounting brackets must be inspected

Answer: (B)

For every accessible area of a conveyor installation, having a pull cord is essential to ensure the safety of workers. A pull cord allows personnel working near the conveyor to quickly stop the operation in case of an emergency or when an unsafe situation arises. This accessibility to an emergency stop is a critical safety feature that enables immediate action to prevent accidents or injuries.

The emphasis on having a pull cord is rooted in safety regulations that guide the design and operation of conveyor systems. By providing an easily reachable means to halt the conveyor, potential hazards, such as being caught in moving parts or other accidents, can be effectively mitigated.

While guarding head and tail pulleys, having a belt slip detection device, and inspecting mounting brackets are important safety measures, they focus on different aspects of conveyor operation and maintenance. Guards prevent access to dangerous parts, detection devices monitor operational integrity, and inspections ensure that the structure remains safe. However, the immediate ability to stop the conveyor is paramount in areas that are frequently accessed by personnel, making the requirement for a pull cord particularly vital.
