Fixed Guards
A fixed guard is a barrier that is permanently attached to the machine. It does not move or open during normal machine operation. This type of guard is called "fixed" because it is always in place and cannot be removed easily without tools.
Fixed Machine Guards
They protect workers by preventing access to areas that could cause injury, such as moving parts or sharp edges. Guards are very important in workplaces to keep everyone safe.
Fixed guards are made from strong materials like sheet metal, wire cloth, plastic, or steel bars. They must be sturdy enough to protect against any impact or wear over time.
Because fixed guards are simple and always in place, they are often the safest choice for preventing accidents.
Materials and Applications
These features make machine guards strong, reliable, and effective at protecting workers:
- Durable materials: Constructed from sheet metal, wire cloth, plastic, or steel bars to ensure long-lasting protection.
- Strong construction: Built to withstand impacts and resist wear over time.
- Permanent placement: Always in place, covering the danger zone without needing adjustment.
- Simple design: Easy to install and maintain, reducing chances of operator error.
- Reliable safety: Offers continuous protection, minimizing risks of accidents.
Examples
- A metal cover placed over a set of belts and pulleys on a conveyor system. The cover completely blocks access to the moving parts, so no one can accidentally touch the belts while they are moving.
- A wire mesh screen around the spinning blades of a fan. The mesh keeps fingers or objects from coming into contact with the blades but allows air to flow through.

Provides a barrier |
Can be constructed to suit many specific applications In-plant construction is often possible Can provide maximum protection Usually requires minimum maintenance Can be suitable to high production, repetitive operations |
May interfere with visibility Can be limited to specific operations Machine adjustment and repair often require its removal, thereby necessitating other means of protection for maintenance personnel |
