OSHA #511 Occupational Safety and Health Standards for General Industry course

What type of guard provides a fixed barrier and is preferred for safety?

1. Adjustable Guard

2. Interlocking Guard

3. Self-Adjusting Guard

4. Fixed Guard

The correct answer is: Fixed Guard

A fixed guard provides a stable and unchanging barrier that effectively prevents access to hazardous areas or moving parts of machinery. This type of guarding is essential because it does not require any active participation from the worker; it remains in position regardless of the operator's actions. This permanence ensures that the risk of accidental contact with dangerous parts is minimized consistently, making it an ideal choice for maintaining a safe working environment. Fixed guards are particularly preferred in situations where the machine's operation does not need adjustment or where the hazards do not change over time. Their rigidity means that they are less likely to be removed or altered, ensuring ongoing protection without necessitating additional safety measures. In contrast, adjustable guards require manual adjustments, which can lead to gaps in safety if they are not properly set. Interlocking guards can fail to function properly if the system malfunctions, potentially allowing access to dangerous areas. Self-adjusting guards may also present risks if they do not respond correctly to varying conditions. Therefore, the stability and reliability of fixed guards make them the safest choice overall.
