Safety glasses marked 'Z87-2+' are not merely for vision correction. They signify passage of a high-impact test, a critical detail separating sight from permanent injury on a job site. Certification confirms protection against high-velocity impacts, a common hazard in construction and trades.
Employers must require and train workers on appropriate PPE. However, subtle differences in certification standards, crucial for actual protection, are often misunderstood or ignored. Oversight creates significant safety gaps.
A widespread lack of detailed PPE standard knowledge among workers and employers will likely lead to preventable injuries and regulatory non-compliance. OSHA Standard 29 CFR 1926.28(a) mandates employers require appropriate PPE in hazardous conditions. All PPE must meet or be equivalent to ANSI standards, according to Procore. Employers must also train workers on PPE necessity, type, use, limitations, care, and disposal, Procore states. Effective PPE is a legally mandated system, combining equipment and comprehensive worker education.
1. Safety Glasses: ANSI Z87.1
Best for: Eye protection against impacts, dust, and chemical splashes.
Safety glasses are a minimum PPE requirement on construction sites. They must comply with ANSI Z87 Standard and include side shields, per EHS Cornell. ANSI Z87.1-certified eyewear passes high mass impact and lens penetration tests. Z87+ indicates a high-velocity impact rating; Z87 alone denotes basic impact, states Safetyglassesusa. 'Z87-2' marks prescription safety glasses; 'Z87-2+' identifies prescription eyewear meeting high-impact requirements. Distinction is critical for adequate protection against specific job site hazards.
Strengths: Essential eye protection, prescription options, clear ANSI impact standards. | Limitations: Basic Z87 may not protect against high-velocity impacts, requires side shields.
