OSHA 1926.100 Head Protection (Construction): what it requires and the equipment it names
29 CFR 1926.100 is the construction hard hat rule. It requires protective helmets where there is a possible danger of head injury from impact, falling or flying objects, or electrical shock and burns, names ANSI Z89.1-2009, 2003 and 1997, and requires the electrical insulation section of Z89.1 (Class E) for employees exposed to high-voltage shock and burns. We sell nationwide; ships in 1–2 business days; most orders arrive in 3–7 business days.
The plain answer
29 CFR 1926.100 requires employees working in areas where there is a possible danger of head injury from impact, from falling or flying objects, or from electrical shock and burns to be protected by protective helmets, and requires the employer to provide head protection meeting ANSI Z89.1-2009, Z89.1-2003 or Z89.1-1997 (or demonstrate equivalence), with helmets for employees exposed to high-voltage electric shock and burns also meeting section 9.7, electrical insulation, of those standards.
It applies to all construction employers; the general industry rule, 1910.135, covers falling objects and exposed conductors but does not name impact. The 2023 OSHA bulletin on safety helmets describes Type II helmets with chin straps for construction and work at height as guidance.
The equipment it names is protective helmets: Type I (top impact) and Type II (top and lateral impact) under Z89.1, in electrical Class G (2,200 volt test), Class E (20,000 volt test) and Class C (no electrical rating), with Class E required by (b)(2) for high-voltage exposure.
What the rule says

29 CFR 1926.100(a): Employees working in areas where there is a possible danger of head injury from impact, or from falling or flying objects, or from electrical shock and burns, are protected by protective helmets.
29 CFR 1926.100(b)(1): The employer provides each employee with head protection meeting ANSI Z89.1-2009, ANSI Z89.1-2003 or ANSI Z89.1-1997, incorporated by reference in 1926.6.
29 CFR 1926.100(b)(2): Head protection for each employee exposed to high-voltage electric shock and burns also meets section 9.7, Electrical Insulation, of the consensus standard, which is the Class E test.
29 CFR 1926.100(b)(3): A device the employer demonstrates is at least as effective as one built to the listed standards is deemed in compliance.
29 CFR 1926.95(c): The helmet is of safe design and selected to properly fit each employee.
29 CFR 1926.501(c): Where an employee is exposed to falling objects on a construction site, each wears a hard hat and the employer erects toeboards, screens or guardrails, a canopy, or barricades the area below.

OSHA 1926.100 Head Protection (Construction) questions
What is the new hard hat standard for construction sites? The rule has not changed: 1926.100(b) still names ANSI Z89.1-2009, 2003 and 1997. What is new is OSHA's December 2023 safety and health information bulletin recommending Type II safety helmets with chin straps for construction, work at height, electrical work and high-temperature work, which is guidance, and the January 2025 fit requirement in 1926.95(c).
Do construction workers have to wear hard hats? Wherever 1926.100(a) applies: a possible danger of head injury from impact, falling or flying objects, or electrical shock and burns. On most construction sites with overhead work that covers the whole site; the employer decides through its hazard analysis and 1926.28(a).
What type of hard hat is required for construction? One built to ANSI Z89.1 (2009, 2003 or 1997), under 1926.100(b)(1); either Type I or Type II meets the paragraph, and Class E is required by (b)(2) where high-voltage shock and burns are possible. Cal/OSHA §3381(c) adds Class E or G below 600 volts and Class E above.
What does the color of a construction hard hat signify? Nothing in the rule. 1926.100 and Z89.1 set impact type and electrical class, not color; color codes for trades and visitors are site or company practice. The HV (high visibility) mark under Z89.1 applies to specific high-visibility shell colors that pass the standard's chromaticity test.
Does OSHA now require chin straps on hard hats? No paragraph requires one. 1926.100 requires a Z89.1 helmet; Type II helmets sold with chin straps are what OSHA's 2023 bulletin recommends for work at height and construction, and the manufacturer's instructions decide when the strap is used. Cal/OSHA §3381 likewise names type and class, not chin straps.
Why do construction workers wear hard hats? Because 1926.100(a) requires protection where head injury from impact, falling or flying objects, or electrical shock and burns is possible, and 1926.501(c) requires a hard hat for anyone exposed to falling objects; the Z89.1 helmet is tested for impact, penetration and (Class E and G) electrical insulation.
