Hard Hat Safety
Dos & Don'ts

OSHA 1926.100 · ANSI/ISEA Z89.1 · NYC BC Chapter 33 — Class E Required on All Sites

TT-011 · Plumb AI Safety · NYC Construction

A hard hat is your first and most visible line of defense against head injuries — from falling objects, overhead work, bumping into structural members, and electrical contact. On every NYC construction site, a hard hat is required the moment you step beyond the site entrance gate. No exceptions, no excuses.

ANSI Classes — Know Which One You Have

Class E (Electrical): Protects against impact and penetration, plus 20,000V electrical contact. Required on all NYC construction sites. Look for "E" on the inside label
Class G (General): Impact and penetration protection; rated for only 2,200V. Not acceptable where electrical hazards exist
Class C (Conductive): Impact only — no electrical protection whatsoever. Never acceptable on construction sites

Pre-Use Inspection — 30 Seconds Every Morning

Check the shell for cracks, deep gouges, dents, or discoloration (UV damage appears as chalky or faded areas)
Check the suspension system inside — 4–8 webbing straps must be intact, not frayed or brittle
Check the sweatband — replace if cracked, torn, or grossly contaminated
If you dropped your hard hat from height, or if it took a significant blow — REPLACE IT immediately, even if no visible damage

What You Cannot Do With a Hard Hat

Do NOT apply stickers over cracks or damage — stickers hide defects that inspectors and you need to see
Do NOT paint the shell — paint dissolves the polycarbonate and weakens the shell without visible signs
Do NOT store on the rear window deck of a vehicle — UV and heat degrade the shell rapidly
Do NOT wear it backwards unless the manufacturer specifically rates it for reverse-donning (most do not)
Do NOT use the hard hat beyond its expiration — shells expire 5 years from manufacture date; suspensions expire 1 year from first use

NYC Site Policy — Zero Tolerance

SSM can issue a written warning for first offense (no hard hat); second offense is removal from site for the day
DOB inspectors entering your site will be wearing hard hats — if they observe workers without them, expect a violation
The manufacture date is stamped inside the shell — check it; a 6-year-old hard hat must be replaced regardless of appearance

Discussion Questions

What is the difference between Class E and Class G hard hats, and which is required on this site?
Your hard hat fell from the 12th floor to the 8th floor platform. The shell looks fine. What do you do?
Where do you find the manufacture date on a hard hat, and when must it be retired?
Why is painting a hard hat dangerous even if the paint seems to be holding fine?
