California OSHA Signs Required

Workplace safety signs are an important part of maintaining a safe and compliant workplace. While OSHA regulations do not require every workplace to display the exact same safety signs, employers must post safety signs and labels whenever hazards exist that require employee awareness.

In California, employers are subject to both federal OSHA requirements and California's own occupational safety program, Cal/OSHA. Proper safety signage helps reduce workplace accidents, communicates hazards clearly, and demonstrates a commitment to employee safety.

This guide explains the types of OSHA safety signs commonly used in California workplaces and how employers can improve compliance.

Why OSHA Safety Signs Matter

Safety signs help employees and visitors quickly recognize hazards before injuries occur.

Proper signage can:

  • Warn employees about hazardous areas.
  • Prevent accidents.
  • Communicate required personal protective equipment (PPE).
  • Identify emergency equipment.
  • Mark exits and evacuation routes.
  • Reduce employer liability.
  • Support OSHA and Cal/OSHA compliance.

Clear, visible signage is an important part of every workplace safety program.

Common OSHA Safety Signs

Depending on the workplace, employers may use signs such as:

  • Danger Signs
  • Warning Signs
  • Caution Signs
  • Notice Signs
  • Biohazard Signs
  • Radiation Signs
  • Hearing Protection Required
  • Eye Protection Required
  • Hard Hat Required
  • Authorized Personnel Only
  • Forklift Traffic
  • No Smoking
  • Emergency Exit
  • Fire Extinguisher Location
  • First Aid Station
  • AED Location
  • Emergency Shower
  • Eyewash Station
  • Lockout/Tagout Warnings

The types of signs required depend on the hazards present in the workplace.

ANSI Safety Sign Categories

Most OSHA safety signs follow ANSI design standards.

Common categories include:

Danger

Used for immediate hazards that could result in death or serious injury.

Warning

Used for hazards that could cause serious injury if not avoided.

Caution

Used for hazards that may result in minor or moderate injuries.

Notice

Used to communicate workplace information or company policies rather than hazard warnings.

Safety Instruction

Used to provide general safety information or required workplace procedures.

Personal Protective Equipment (PPE) Signs

Many workplaces require signs reminding employees to wear appropriate PPE.

Examples include:

  • Safety Glasses Required
  • Hearing Protection Required
  • Hard Hat Area
  • Face Shield Required
  • Respirator Required
  • Protective Gloves Required
  • Steel Toe Footwear Required
  • High Visibility Vest Required

PPE signs should be placed before employees enter the affected work area.

Emergency Signs

Emergency signs help employees respond quickly during emergencies.

Common emergency signs include:

  • Exit
  • Emergency Exit
  • Fire Extinguisher
  • First Aid
  • AED
  • Emergency Eyewash
  • Emergency Shower
  • Assembly Area
  • Fire Alarm Pull Station

Emergency equipment should remain clearly marked and unobstructed at all times.

Where Safety Signs Should Be Posted

Employers should place signs where employees can easily see them before entering a hazardous area.

Typical locations include:

  • Warehouse entrances
  • Manufacturing equipment
  • Construction zones
  • Chemical storage rooms
  • Electrical rooms
  • Forklift traffic areas
  • Machine guarding areas
  • Laboratories
  • Loading docks
  • Emergency exits

Signs should remain visible, legible, and in good condition.

Maintaining OSHA Sign Compliance

California employers should:

  • Inspect workplace signs regularly.
  • Replace damaged or faded signs.
  • Add signs whenever new hazards are introduced.
  • Train employees on the meaning of workplace safety signs.
  • Review signage during annual safety inspections.
  • Ensure signs remain visible and unobstructed.

Proper maintenance helps keep employees informed and improves overall workplace safety.

Labor Law Posters vs. OSHA Safety Signs

Labor law posters and OSHA safety signs serve different purposes.

Labor law posters provide employees with legally required information about wages, discrimination, leave, and workplace rights.

OSHA safety signs warn employees about specific hazards and provide safety instructions within the workplace.

Most employers need both types of postings to maintain compliance.
