Helmets, eye & hearing protection
PPE is rated for the hazard: electrical class, impact and lateral protection, eye and hearing ratings all have to match the job.
Safety features explained
Class E electrical rating
ANSI Z89.1 Class E helmets are dielectrically tested to 20,000 V — required where electrical contact is possible.
Lateral impact & retention (EN 12492)
Climbing-style helmets add side, front and rear impact protection plus a chin strap that keeps the helmet on in a fall.
Rated eye and hearing protection
Z87.1 lenses resist impact; mesh visors stop chips but not dust, and hearing protection is selected by NRR for the saw or chipper.
Daily inspection checklist
- 1Check the shell for cracks, dents, chalking, deep gouges and UV fading.
- 2Inspect the suspension, harness webbing, ratchet and chin strap for wear and clean function.
- 3Confirm the date of manufacture and replace per the manufacturer's schedule.
- 4Check lenses and mesh for scratches, cracks, missing screws and bent frames.
- 5Inspect muffs for cracked cups, hardened seals and flattened headband tension; replace foam plugs daily.
Out of service now
- Helmet that took an impact, or shows any crack or chalky shell.
- Missing or broken chin strap where a chin strap is required.
- Painted or solvent-exposed shell (hides damage and can degrade it).
- Scratched-opaque lenses, or muffs with hardened, leaking seals.
Operating best practices
- Wear the chin strap in the tree, in the bucket, and any time a fall or a struck-by is possible.
- Match electrical class to the job — Class E for any work near energized conductors.
- Double up on hearing protection around chippers and stump grinders in tight urban reflections.
- Retire PPE by date and by damage, and keep replacements on the truck.
Standards & compliance
- ANSI Z133: head, eye, hearing and leg protection are required for the tasks that generate the hazard.
- ANSI Z89.1 Type I/II, Class E/G/C for helmets; EN 12492 for climbing-style helmets.
- ANSI Z87.1 for eye and face protection; OSHA 1910.95 for hearing conservation.
Summarised for field use. The current ANSI Z133 standard, OSHA rules and the manufacturer's manual are the controlling documents.
