Colorado OSHA Signs Required Guide

Safety signs play an important role in protecting employees, customers, contractors, and visitors from workplace hazards. While OSHA does not require every workplace to display the same signs, employers are generally required to use signs and labels whenever they are necessary to warn people about hazards, provide emergency information, or communicate safety instructions.

Colorado private-sector employers are generally regulated by federal OSHA, while public-sector employees are covered by Colorado's Public Sector Safety and Health Program. Employers should evaluate their workplaces to determine which safety signs are required based on their industry, equipment, and workplace hazards.

This guide outlines many of the most common OSHA safety signs used in Colorado workplaces.

Danger Signs

Danger signs identify hazards that present an immediate risk of serious injury or death.

Examples include:

  • High voltage
  • Confined space entry
  • Hazardous machinery
  • Chemical hazards
  • Fall hazards
  • Energized electrical equipment

Danger signs should be highly visible and placed near the hazard they identify.

Warning Signs

Warning signs alert employees to hazards that could cause serious injury if proper precautions are not taken.

Common examples include:

  • Forklift traffic
  • Hot surfaces
  • Moving machinery
  • Crushing hazards
  • Elevated work areas
  • Overhead loads

Warning signs help employees recognize potentially dangerous conditions before entering hazardous areas.

Caution Signs

Caution signs identify hazards that may cause minor or moderate injuries.

Typical caution signs include:

  • Wet floor
  • Slippery surface
  • Low clearance
  • Trip hazards
  • Uneven flooring
  • Watch your step

These signs help prevent common workplace accidents.

Personal Protective Equipment (PPE) Signs

Where personal protective equipment is required, employers should clearly notify employees through appropriate signage.

Examples include:

  • Safety glasses required
  • Hearing protection required
  • Hard hats required
  • Respirators required
  • Protective gloves required
  • Steel-toe footwear required
  • Face shields required

PPE signs reinforce workplace safety policies and remind employees to wear required protective equipment.

Exit and Emergency Signs

Emergency signage should clearly identify evacuation routes and emergency equipment.

Common signs include:

  • Exit
  • Emergency Exit
  • Fire Exit
  • Emergency Assembly Area
  • Tornado Shelter
  • Emergency Eyewash Station
  • Emergency Shower
  • First Aid Station

Clearly marked emergency routes help employees respond quickly during emergencies.

Fire Safety Signs

Employers should properly identify fire protection equipment.

Examples include:

  • Fire Extinguisher
  • Fire Alarm Pull Station
  • Fire Hose
  • Fire Sprinkler Control
  • No Smoking
  • Flammable Materials
  • Fire Door — Keep Closed

These signs help employees locate emergency equipment and reduce fire risks.

Hazard Communication Signs

Employers working with hazardous chemicals should ensure containers, storage areas, and workspaces are properly labeled.

Hazard communication may include:

  • Chemical storage labels
  • Compressed gas warnings
  • Corrosive material signs
  • Toxic material warnings
  • Oxidizer labels
  • GHS hazard pictograms

Proper labeling is a key part of OSHA's Hazard Communication Standard.

Machine Safety Signs

Industrial workplaces often require signage warning employees about machinery hazards.

Examples include:

  • Keep Hands Clear
  • Lockout/Tagout Required
  • Authorized Personnel Only
  • Machine Starts Automatically
  • Rotating Equipment
  • Pinch Point
  • Do Not Operate

Proper machine signage helps reduce serious workplace injuries.

OSHA Poster Requirements

In addition to workplace safety signs, most Colorado employers covered by OSHA are required to display the official OSHA Job Safety and Health: It's the Law poster where employees can easily read it.

Colorado employers are also generally required to display current Colorado and federal labor law posters covering employee workplace rights.

Employer Best Practices

Colorado employers should:

  • Conduct regular workplace hazard assessments.
  • Install safety signs wherever hazards exist.
  • Replace damaged or faded signs promptly.
  • Train employees on workplace safety signs.

Routine safety inspections help ensure signage remains accurate and visible.
