Machine safeguards must meet these minimum general requirements: Prevent contact: The safeguard must prevent hands, arms or any other part of a worker’s body from contacting dangerous moving parts. Be secure: Workers should not be able to easily remove or tamper with the safeguard.
What is a gotcha stick used for?
Universal Safety Scale (“Gotcha Stick”) MSS’s Universal Safety Scale (Universal “Gotcha Stick”) is used to test the allowable guard opening size to ensure personnel cannot reach the hazard and that openings in barrier guards comply with OSHA and ANSI standards for machine safeguarding.
What do safeguarding devices do to protect the worker OSHA?
Guards provide physical barriers that prevent access to dangerous areas. Safeguarding devices either prevent or detect operator contact with the point of operation or stop potentially hazardous machine motion if any part of a worker’s body is within the hazardous portion of the machine.
Which of the following machine parts always require guards OSHA?
Revolving barrels, containers, and drums must be guarded by an enclosure interlocked with the drive mechanism, so the barrel, gun, or container cannot revolve unless the guard enclosure is in place.

- The point of operation. That point where work is performed on the material, such as cutting, shaping, boring, or forming of stock.
- Power transmission apparatus.
- Other moving parts.
What will a safe distance scale do?
This three-segment safe distance stick accurately tests the allowable barrier opening size based on the distance from the point of operation. It features English measurements on one side, and Metric measurements on the other.
What is meant by machine guarding?
Machine guarding is a safety feature on or around manufacturing or other engineering equipment consisting of a shield or device covering hazardous areas of a machine to prevent contact with body parts or to control hazards like chips or sparks from exiting the machine.
What are three primary categories of machine guarding?
- Guards – these are physical barriers that prevent contact.
- Devices – these limit or prevent access to the hazardous area.
- Automated Feeding and Ejection Mechanisms – These eliminate the operator’s exposure to the point of operation while handling stock (materials).
