According to OSHA 29 CFR 1926.95, what is the minimum impact resistance requirement for safety glasses lenses?
Correct Answer
A) ANSI Z87.1
OSHA requires safety glasses to meet ANSI Z87.1 standards for impact resistance and optical clarity. This standard ensures adequate protection against workplace eye hazards in construction environments.
Why This Is the Correct Answer
ANSI Z87.1 is the correct standard because OSHA 29 CFR 1926.95 specifically references this American National Standards Institute standard for eye and face protection in construction. This standard establishes minimum requirements for impact resistance, optical quality, and other protective features of safety glasses. The Z87.1 standard ensures that safety glasses can withstand high-velocity impact from flying particles and debris commonly found in construction environments. OSHA adopted this industry-recognized standard to provide consistent protection requirements across all construction sites.
Why the Other Options Are Wrong
Option B: ANSI Z89.1
ANSI Z89.1 is the standard for industrial head protection (hard hats), not eye protection. This standard covers requirements for protective helmets used in industrial and construction environments to protect against impact, penetration, and electrical hazards.
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 nothing to do with eye protection or safety glasses impact resistance requirements.
Option D: ASTM F1447
ASTM F1447 is a standard related to helmets used in bicycling, not construction safety glasses. ASTM standards, while important in various industries, are not the referenced standard for construction eye protection under OSHA regulations.
Memory Technique
Remember 'Z87.1 = Eyes' - the number 87 looks like glasses when you turn the 8 sideways, and Z87.1 is always the eye protection standard.
