Accepted Answer

No. 4

Answer

When gas welding or burning, welders are required to wear tinted goggles or welding hoods with a filter lens of not less than a No. 4 shade.

Using the correct filter lens is crucial for preventing eye damage such as arc flash or cataracts.

Question 2

What is the best way to protect yourself when working near moving vehicles and equipment?

Accepted Answer

Wear a reflective or high-visibility vest.

Answer

Wearing a reflective or high-visibility vest is the most effective way to protect yourself when working near moving vehicles and equipment. This makes you easily visible to equipment operators and drivers, especially in low light conditions or busy work zones. Increased visibility significantly reduces the risk of accidents and injuries by ensuring you are seen.

If a Code of Federal Regulations Standard (like OSHA standards) does not specifically address a workplace hazard, the General Duty Clause of the OSH Act must be invoked. This clause requires employers to provide a workplace free from recognized hazards that are causing or are likely to cause death or serious physical harm to employees. It acts as a catch-all to ensure worker safety even when specific regulations are absent.
