Maryland OSHA Safety Signs Guide

Maryland operates its own OSHA-approved occupational safety and health program known as Maryland Occupational Safety and Health (MOSH). Employers are responsible for providing a workplace free from recognized hazards and using appropriate signs, labels, markings, and warnings whenever required by OSHA or MOSH standards. In addition, covered employers must display the official MOSH workplace poster and other required employment notices.

The exact safety signs needed depend on the employer's industry, equipment, chemicals, and workplace hazards.

Required Maryland Workplace Posters

Most Maryland employers should display applicable workplace notices, including:

  • Maryland Occupational Safety and Health (MOSH) Poster
  • Maryland Minimum Wage and Overtime Poster
  • Maryland Earned Sick and Safe Leave Notice
  • Employment Discrimination Notice
  • Workers' Compensation Notice
  • Equal Pay for Equal Work Notice
  • Required federal labor law posters

Employers should review official Maryland posting requirements regularly and replace outdated notices when revised versions are issued.

Hazard Communication Signs

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

Common hazard communication signs include:

  • Flammable Material
  • Corrosive Material
  • Toxic Chemicals
  • Oxidizer
  • Compressed Gas
  • Chemical Storage Area
  • Safety Data Sheets (SDS) Location
  • Hazardous Waste Area

Employers should also:

  • Label chemical containers.

  • Train employees on chemical hazards.

Personal Protective Equipment (PPE) Signs

Many Maryland workplaces use PPE reminder signs, including:

  • Safety Glasses Required
  • Hard Hat Required
  • Hearing Protection Required
  • Respirator Required
  • Protective Gloves Required
  • Face Shield Required

PPE signs should be posted before employees enter hazardous work areas.

Emergency signs help employees locate emergency equipment quickly.

Common emergency signs include:

  • EXIT
  • Emergency Exit
  • Fire Extinguisher
  • AED Location
  • First Aid Station
  • Emergency Eyewash
  • Safety Shower

Emergency exits and equipment should remain clearly marked and unobstructed.

Equipment Warning Signs

Many workplaces post warning signs near hazardous equipment, including:

  • High Voltage
  • Lockout/Tagout Required
  • Moving Machinery
  • Pinch Point
  • Crush Hazard
  • Hot Surface
  • Rotating Equipment
  • Authorized Personnel Only

Warning signs should be positioned where employees will see them before entering hazardous areas.

Warehouse Safety Signs

Warehouses commonly use signs such as:

  • Forklift Traffic
  • Watch for Forklifts
  • Pedestrian Crossing
  • Speed Limit
  • Loading Dock
  • Falling Object Hazard

Proper warehouse signage helps reduce collisions between forklifts and pedestrians.

  • Fall Protection Required
  • Open Excavation
  • Crane Overhead
  • Danger – High Voltage

Construction warning signs should remain visible whenever the hazard exists. OSHA regulations require accident-prevention signs to remain visible while work is being performed and to be removed or covered once the hazard no longer exists.

ANSI Safety Sign Categories

Many Maryland employers follow ANSI Z535 standards for consistent workplace safety communication.

Common categories include:

  • Danger
  • Warning
  • Caution
  • Notice
  • Safety Instructions
  • Fire Safety
  • Biohazard

Using standardized safety signs helps employees quickly recognize hazards and appropriate precautions.

Safety Sign Maintenance

Maryland employers should routinely inspect workplace signs to ensure they remain:

  • Clearly visible
  • Easy to read
  • Properly mounted
  • Undamaged
  • Appropriate for current hazards
  • Replaced if faded or outdated

Routine inspections help improve workplace safety and support MOSH compliance.
