What is the minimum degree allowed by OHS for grinder guards?

90°
120°
180°
Not specified

The correct answer is: Not specified

Grinder guards should be at least 180° for optimal safety. Answer A (90°) is too narrow and would not provide enough coverage. Answer B (120°) is still not ideal and leaves room for potential accidents. Answer C (180°) is the recommended minimum degree to ensure proper protection while operating a grinder. Answer D (not specified) may not be the best choice, as there are specific safety guidelines to follow when it comes to grinder guards. It is important to always check the manufacturer's instructions for the specific grinder being used.
