Every recommendation on this site traces back to one of the standards bodies below. Here’s what each one actually is and what it governs — so “ANSI Z87.1” or “OSHA 1910.95” means something concrete, not just a string of letters and numbers.

ANSI

Suggested H1: ANSI Standards for Safety Gear

ANSI (the American National Standards Institute) doesn’t write a single safety standard — it accredits the consensus process behind dozens of them, each covering a specific category of equipment. On this site, three ANSI standards come up most often, depending on which part of the body is being protected:

  • ANSI/ISEA Z87.1 covers eye and face protection. It defines how safety glasses, goggles, and face shields are tested for impact resistance, and it’s the source of the “Z87” and “Z87+” markings stamped on lenses and frames — Z87 for basic impact, Z87+ for high-velocity impact from grinding, chipping, or fastener-driving work.
  • ANSI/ISEA Z89.1 covers head protection. It’s the standard behind hard hat Type (top-impact vs. top-and-side impact) and Class (electrical insulation) ratings.
  • ANSI/ASSP Z359 covers fall protection. It’s actually a family of standards spanning full-body harnesses, energy-absorbing lanyards, self-retracting lifelines, and anchorage connectors, each governed by its own sub-standard within the Z359 series.

Every article in this hub that recommends eye protection, head protection, or fall protection gear ties its claims back to the relevant ANSI standard rather than a manufacturer’s marketing copy.

OSHA

Suggested H1: OSHA Regulations for Workplace Safety

OSHA (the Occupational Safety and Health Administration) sets the legal floor for PPE in U.S. workplaces. The starting point is 29 CFR 1910.132, the general industry standard requiring employers to assess their workplace for hazards, select PPE that addresses those hazards, and train workers on its proper use — before any specific type of gear even enters the picture.

From there, each category of protective equipment has its own OSHA subsection: head protection falls under 1910.135 (or 1926.100 for construction), eye and face protection under 1910.133, and so on. When an article on this site references an OSHA requirement, we cite the specific regulation behind it rather than a vague “OSHA requires this” claim.

ASTM

Suggested H1: ASTM Standards for Protective Footwear

ASTM International writes performance standards across a huge range of industries, but the one that matters most for the gear we cover is ASTM F2413, the U.S. performance specification for protective toe-cap footwear. It sets the minimum impact and compression resistance a safety boot’s toe cap must withstand, regardless of whether it’s built from steel, alloy, or composite material, and it defines the supplemental protection codes stamped inside every compliant boot — things like EH (electrical hazard), PR (puncture resistant), and Mt (metatarsal protection). If a work boot claims a safety rating, that claim should be traceable to an F2413 marking, not just a product description.

NIOSH

Suggested H1: NIOSH Standards for Respiratory Protection

NIOSH (the National Institute for Occupational Safety and Health) is the federal agency responsible for testing and certifying respirators before they can be sold for occupational use in the U.S., under the framework laid out in 42 CFR Part 84. This is where the familiar N95, N99, N100, R95, and P100 ratings come from: the letter (N, R, or P) indicates how the filter holds up against oil-based particles, and the number indicates the minimum percentage of airborne particles it filters out. A respirator that isn’t NIOSH-approved under 42 CFR 84 shouldn’t be relied on for occupational protection, no matter what it’s marketed as.

NFPA

Suggested H1: NFPA Standards for Electrical Safety

The NFPA (National Fire Protection Association) publishes codes covering fire and electrical safety, and the one most relevant to the gear on this site is NFPA 70E, the standard for electrical safety in the workplace. It governs how employers assess arc-flash risk and select appropriate PPE — including how head, eye, and body protection factor into a broader arc-flash safety strategy — for anyone working near energized electrical equipment. Where a piece of gear is relevant to electrical work, we reference NFPA 70E alongside the ANSI or OSHA standard that applies to that equipment category.

This page describes what these organizations are and generally govern. For the authoritative, current text of any specific standard, consult that standard body directly — standards are periodically revised, and this page is a general reference, not a substitute for the official published standard.
