Illinois OSHA Signs Required Guide

Safety signs play an important role in helping employers communicate workplace hazards, emergency procedures, required protective equipment, and other important safety information. While OSHA does not require every workplace to display the same signs, employers must post safety signage whenever required by OSHA standards or when it is necessary to warn employees about workplace hazards.

Proper safety signs help reduce accidents, improve hazard awareness, and support OSHA compliance.

This guide explains the types of OSHA safety signs Illinois employers should consider for their workplaces.

OSHA Workplace Poster

Most employers covered by OSHA must display the official Job Safety and Health: It's the Law poster where employees can easily see it.

The poster informs employees about their workplace safety rights and explains how to report unsafe working conditions.

The poster should remain current and be displayed in a conspicuous location that employees regularly access.

Danger Signs

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

Examples include:

  • High voltage.
  • Confined space.
  • Chemical hazards.
  • Machine hazards.
  • Explosion hazards.
  • Arc flash hazards.
  • Fall hazards.

Danger signs should be placed as close as practical to the hazard.

Warning Signs

Warning signs identify hazards that could cause serious injury if proper precautions are not followed.

Common examples include:

  • Moving machinery.
  • Hot surfaces.
  • Forklift traffic.
  • Crush hazards.
  • Overhead loads.
  • Slip hazards.
  • Radiation hazards where applicable.

Warning signs remind employees to remain alert around potentially dangerous conditions.

Caution Signs

Caution signs identify hazards that could result in minor or moderate injuries.

Examples include:

  • Wet floors.
  • Trip hazards.
  • Low overhead clearance.
  • Uneven walking surfaces.
  • Minor pinch points.
  • Recently cleaned floors.

These signs help reduce common workplace accidents.

Personal Protective Equipment (PPE) Signs

Employers should post PPE signs wherever protective equipment is required.

Examples include:

  • Safety glasses required.
  • Hearing protection required.
  • Hard hats required.
  • Respirators required.
  • Face shield required.
  • Protective gloves required.
  • Safety footwear required.
  • High-visibility vest required.

PPE reminder signs reinforce employee training and improve compliance.

Exit and Emergency Signs

Emergency signs help employees evacuate safely during emergencies.

Typical signs include:

  • Exit.
  • Emergency Exit.
  • Exit Route.
  • Area of Refuge.
  • Emergency Assembly Area.
  • First Aid Station.
  • AED Location.
  • Emergency Shower.

Emergency signs should remain visible at all times.

Fire Safety Signs

Fire protection signs help employees quickly locate emergency equipment.

Examples include:

  • Fire Extinguisher.
  • Fire Hose.
  • Fire Alarm Pull Station.
  • Sprinkler Control Valve.
  • Fire Department Connection.
  • No Smoking.
  • Flammable Storage.

Employers should ensure fire equipment remains accessible and properly identified.

Hazard Communication Signs

Employers using hazardous chemicals should comply with OSHA's Hazard Communication Standard.

Workplaces may require signs identifying:

  • Chemical storage areas.
  • Flammable materials.
  • Corrosive materials.
  • Toxic substances.
  • Oxidizers.
  • Compressed gases.
  • Authorized personnel only.

Hazard communication signs should work together with container labels and Safety Data Sheets (SDSs).

Lockout/Tagout Signs

Facilities servicing or maintaining machinery may require lockout/tagout signs such as:

  • Do Not Operate.
  • Locked Out.
  • Authorized Personnel Only.
  • Equipment Under Maintenance.

These signs help protect employees during maintenance and repair activities.

Traffic and Warehouse Safety Signs

Warehouses and industrial facilities often use additional safety signs including:

  • Forklift Crossing.
  • Pedestrian Walkway.
  • Speed Limit.
  • Stop.
  • Loading Dock Safety.
  • Overhead Crane.
  • Keep Clear.
  • Authorized Personnel Only.

These signs help separate pedestrian and vehicle traffic while reducing workplace accidents.

OSHA Sign Inspection

Employers should routinely inspect workplace signs to ensure they are:

  • Clearly visible.
  • Easy to read.
  • Properly mounted.
  • Not faded or damaged.
  • Appropriate for current workplace hazards.
  • Replaced when necessary.

Regular inspections help maintain an effective workplace safety program.
