Understanding ANSI Z87.1 Standards for Safety Glasses

Understanding ANSI Z87.1 Standards for Safety Glasses

2025-Jan-15

ANSI Z87.1 is a voluntary standard developed by the American National Standards Institute that establishes minimum requirements for the performance of occupational eye and face protection devices.

Key Requirements of ANSI Z87.1:

  • Impact Resistance: Safety glasses must withstand a high-velocity impact from a small steel ball without shattering or penetrating the lens.
  • High-Mass Impact Resistance: Safety glasses must also withstand a low-velocity impact from a larger steel ball.
  • Lens Penetration Resistance: The lenses must resist penetration by a fine wire.
  • Optical Clarity: The lenses must provide clear vision without significant distortion.
  • Frame Strength: The frames must be strong enough to withstand impact and prevent the lenses from dislodging.

Understanding Z87+ and Z87 Markings:

  • Z87+: This marking indicates that the safety glasses meet the highest level of impact resistance requirements in ANSI Z87.1.
  • Z87: This marking indicates that the safety glasses meet the basic impact resistance requirements in ANSI Z87.1.

Importance of ANSI Z87.1 Compliance:

  • Worker Safety: ANSI Z87.1 compliant safety glasses provide workers with the best possible protection against eye injuries.
  • Employer Liability: Employers have a legal obligation to provide their employees with safe working conditions, including appropriate eye protection.
  • Industry Standards: Many industries have specific requirements for the use of ANSI Z87.1 compliant safety glasses.

Choosing ANSI Z87.1 Compliant Safety Glasses:

  • Look for the Z87+ or Z87 marking: Ensure that the safety glasses you choose are clearly marked with the appropriate ANSI Z87.1 marking.
  • Choose reputable brands: Select safety glasses from reputable brands known for their quality and compliance with ANSI Z87.1 standards.
  • Purchase from authorized dealers: Purchase safety glasses from authorized dealers to ensure that you are receiving genuine ANSI Z87.1 compliant products.
