According to ANSI Z 49.1, what thickness is recommended for a face shield?

• A. 1 to 2 filter
• B. 3 to 6 filter
• C. 4 to 8 filter
• D. 1 to 5 filter

Answer: (B)

The correct choice specifies a thickness of 3 to 6 filter for a face shield, which aligns with ANSI Z 49.1 guidelines for oxyfuel cutting operations. This range provides adequate protection for the eyes and face from harmful light radiation, including infrared and ultraviolet rays produced during cutting processes. A face shield with this filter thickness enables workers to perform their tasks safely while ensuring clarity of vision without compromising safety. The recommended thickness is crucial because insufficient protection could expose workers to eye damage or injuries from sparks and molten metal. Choices that suggest lower or excessively high filter thicknesses may not provide the balanced protection necessary for effective visibility and safety during oxyfuel cutting tasks. It's important to adhere to established safety standards like ANSI Z 49.1 to ensure a safe working environment.
