What color do maintenance workers wear?

1. High-Visibility Colors (Most Common)

• Fluorescent Yellow-Green or Orange:
  • Why: Maximizes daytime visibility (ANSI/ISEA 107 Class 2/3 standards).
  • Used in: Construction sites, roadwork, warehouses, airports, or any area with moving vehicles/machinery.
  • Details: Often paired with reflective silver stripes for night visibility.
  • 

2. Dark & Stain-Hiding Colors

• Navy, Charcoal, or Black:
  • Why: Conceals grease, oil, and dirt in industrial settings (e.g., mechanics, factory equipment repair).
  • Common in: Indoor workshops, automotive garages, manufacturing plants.
  • 

3. Industry-Specific Colors

• Utilities (Electric/Gas):
  • Blue or Gray: Standard for technicians (e.g., HVAC, plumbing).
• Aircraft Maintenance:
  • Light Gray or Beige: Reduces heat absorption in hangars.
• Hospital/Facility Maintenance:
  • White or Light Blue: Matches clinical environments.

Key Factors Influencing Color Choice

When Bright Colors Are REQUIRED

• Working near forklifts, cranes, or traffic.
• Low-light areas (warehouses, tunnels).
• Emergency response roles.
  Regulatory Note: OSHA (U.S.) and EU EN ISO 20471 mandate hi-vis gear in high-risk zones.

Exceptions to Avoid

• ❌ Red: Rarely used (camouflages blood stains).
• ❌ Camouflage: Banned on most sites (safety confusion).
• ❌ All-White: Impractical for dirty tasks (shows stains).

Pro Tip

Example: Dark navy work pants + fluorescent yellow vest (removed indoors).
This balances visibility needs with practicality for messy tasks.
