According to OSHA standards, what is the minimum impact resistance requirement for safety glasses worn on construction sites?
Correct Answer
D) ANSI Z87.1
OSHA 29 CFR 1926.95 requires that safety glasses meet ANSI Z87.1 standards for impact resistance. This standard ensures adequate protection against flying particles and debris common on construction sites.
Why This Is the Correct Answer
ANSI Z87.1 is the correct standard because it specifically addresses occupational and educational personal eye and face protection devices. OSHA 29 CFR 1926.95(a) explicitly requires that protective eye and face equipment comply with ANSI Z87.1 standards for impact resistance. This standard establishes the minimum requirements for safety glasses to protect against high-velocity impact from flying particles, which is a common hazard on construction sites.
Why the Other Options Are Wrong
Option A: ANSI Z89.1
ANSI Z535.1 is the standard for safety colors, which deals with the specification of colors used for safety signs and markings. This standard is completely unrelated to personal protective equipment or impact resistance testing for safety glasses.
Option B: ANSI Z535.1
ANSI Z89.1 is the standard for industrial head protection (hard hats), not eye protection. While hard hats are also required PPE on construction sites, this standard does not address safety glasses or impact resistance requirements for eye protection.
Option C: ANSI Z359.1
ANSI Z359.1 is the standard for fall protection and fall arrest systems, including harnesses, lanyards, and anchor points. This standard has no relation to eye protection or safety glasses impact resistance requirements.
Memory Technique
Use the mnemonic 'Z87 = Eyes' and remember that all the Z-standards have different purposes: Z87 (eyes), Z89 (head), Z359 (fall protection), Z535 (colors). Focus on the '87' number association with eye protection.
