1. Fixed guards: Fixed guards are physical barriers that are permanently attached to the machine to prevent access to hazardous areas. They are typically made of metal or other durable materials and are designed to withstand impact and prevent tampering. Fixed guards are commonly used in high-risk areas where there is a high likelihood of injury if a person comes into contact with moving parts or other hazards.
2. Interlocked guards: Interlocked guards are designed to automatically shut off or disable the machine when the guard is opened or removed. This type of guarding system ensures that the machine cannot be operated without the guard in place, reducing the risk of injury to operators. Interlocked guards are commonly used in situations where frequent access to the machine is required, such as for maintenance or cleaning.
3. Adjustable guards: Adjustable guards are designed to be easily moved or repositioned to accommodate different types of materials or processes. These guards can be adjusted to provide adequate protection while still allowing for efficient operation of the machine. Adjustable guards are commonly used in situations where the size or shape of the material being processed may vary, requiring the guard to be adjusted accordingly.
4. Presence-sensing devices: Presence-sensing devices are electronic sensors that detect when a person or object is in close proximity to the machine and automatically shut off or disable the machine to prevent injury. These devices can include light curtains, laser scanners, or pressure-sensitive mats that trigger the machine to stop when they detect an obstruction. Presence-sensing devices are commonly used in situations where physical guards may not be practical or effective, such as on robotic or automated machines.

Four Types of Machine Guarding
1. Fixed Guards:
- Permanently attached to the machine frame or structure.
- Prevents access to hazardous moving parts by enclosing them or blocking access points.
- Examples: Sheet metal enclosures, grating covers, safety cages.
2. Interlocking Guards:
- Mechanically linked to the machine's operation.
- Automatically deactivate the machine when the guard is opened or removed.
- Examples: Interlocked doors, safety switches, pull-out interlocks.
3. Adjustable Guards:
- Can be repositioned to suit different machine operations or workpiece configurations.
- Protects operators from hazards while allowing flexibility in the machine's use.
- Examples: Adjustable guarding around rotating shafts, point-of-operation guards.
4. Behavioral Guards:
- Rely on the operator's awareness and appropriate actions.
- Encourage safe machine use through warning labels, signs, and training.
- Examples: Warning lights, audible alarms, personal protective equipment (PPE).
