Dear All, I am initiating this thread to discuss and come to a conclusion on the requirement of emergency stopping devices in belt conveyors. If pull cords are installed along the entire length of a belt conveyor, is that sufficient protection? Do we need to have emergency stop buttons along the entire length of the conveyor in addition to these pull cords? The website below mentions the need for pull cords and push buttons along the entire length of belt conveyors: https://www.hsa.ie/eng/Your_Industry..._-_pull_wires/
Does any of your sites have these E-Stops along the entire length of the conveyor apart from pull cords as safety protection means? Is this a legal requirement in any part of the world, or is it just a best management practice? Do let me know your thoughts on this...

Ensuring Safety in Conveyor Belt Operations
If any workforce is required to check the conveyor belt and the pulleys for foreign particles, it is better to provide a powerful sensor near the pulleys. I came across an accident when the pickers were removing foreign particles (metals) from the limestone conveyor belt to the crusher in the cement industry. The worker's head was pulled in along with his turban between the pulley and the conveyor belt despite having enough pull cords and push buttons provided. The worker's body got caught between the conveyor and pulleys and died on the spot. The belt tripped very late.

Dear Sir,
I appreciate the response.
What you mean by “provide a powerful sensor near the pulleys?” Is that something beyond the Emergency Stops and Pull Cords? Are you referring to provide some Light curtains sort of installation?
Can you please comment on the need of providing the Emergency Stops across the length of the conveyor in addition to having the pull cords? This will serve as a secondary means of protection, in case the full cords fail to function.

Safety Measures in Elevators and Conveyor Belts
Mr. Dipil Kumar, I mean a light curtain/sensor is normally provided in elevators. The most dangerous area is the pulleys, where the conveyor belt rotates. Sometimes, hands and fingers can be pulled in, even though a trip/overload switch is provided.
The Importance of Emergency Stop Switches
The need for providing an emergency stop switch/pull cord is basically when the pickers find foreign particles that can damage the crusher's jaws (mostly the metal teeth from the excavators) or different kinds of stones that can deteriorate the quality of the limestone. They have to stop the conveyor belt in that line, pick, and remove it.

Thank you for the response. Have you come across any conveyors in India or anywhere in the world where light curtains/sensors are installed in addition to the pull cords/emergency stops? If so, could you please share more details about it, along with a photograph if possible?
Regarding the emergency stop and pull cords, based on your post, I understand that we only need one of the above. However, it is a legal requirement in Canada and Ireland to provide emergency stops along the entire length of the conveyor, in addition to the pull cord. I am seeking more references and logical reasoning to present this requirement to my client.
Thank you.
