Type 2 vs Type 1 Hard Hats
| Feature | Type 1 | Type 2 (Recommended) |
|---|---|---|
| Impact Protection | Top only | Top + Side |
| Major GC Acceptance | Being phased out | Required |
| CSA Standard | Z94.1 | Z94.1 (lateral) |
| Cost | $15-30 | $40-80 |
Hard Hat Sticker Rules
Stickers on hard hats are permitted but must meet specific requirements:
- ✅ Non-metallic — Metallic stickers affect electrical protection rating
- ✅ Vinyl material — Won't damage shell integrity
- ✅ No adhesive damage — Use "safety-safe" adhesives
- ✅ No coverage of defects — Stickers can't hide cracks or damage
- ❌ No paint — Paint can degrade shell material
