Missouri OSHA Signs Required Guide

Missouri private employers are regulated by Federal OSHA rather than a state OSHA plan. While OSHA does not require every workplace to display the same warning signs, employers must use signs, labels, tags, markings, and other warnings whenever required by OSHA standards or when necessary to communicate workplace hazards. Missouri employers must also display required state and federal workplace posters in locations where employees can easily see them.

The specific safety signs required depend on the type of workplace, equipment, chemicals, and hazards present.

Required Workplace Posters

Most Missouri employers should display applicable workplace notices, including:

  • OSHA Job Safety and Health: It's the Law Poster
  • Missouri Minimum Wage Law Poster
  • Missouri Workers' Compensation Notice
  • Missouri Unemployment Benefits Notice
  • Missouri Human Rights Act (Equal Employment Opportunity) Poster
  • Other industry-specific notices when applicable

Posters should be displayed where employees regularly work or gather and replaced whenever updated versions become available.

Hazard Communication Signs

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

Common hazard communication signs include:

  • Chemical storage warnings
  • Flammable material signs
  • Corrosive material signs
  • Compressed gas warnings
  • Toxic material signs
  • Safety Data Sheet (SDS) location notices
  • Hazard labels on containers

Employers must also maintain a written Hazard Communication Program and train employees on chemical hazards.

Personal Protective Equipment (PPE) Signs

Many Missouri workplaces post signs reminding employees to wear required PPE.

Examples include:

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

PPE reminder signs should be placed near entrances to hazardous work areas.

Emergency Signs

Emergency signage helps employees respond quickly during emergencies.

Common emergency signs include:

  • EXIT signs
  • Emergency Exit
  • Fire Extinguisher
  • First Aid Station
  • AED Location
  • Emergency Eyewash Station
  • Safety Shower
  • Emergency Assembly Area
  • Emergency Telephone

Emergency routes should remain clearly marked and unobstructed.

Equipment Warning Signs

Workplaces often require warning signs near hazardous equipment, including:

  • High Voltage
  • Lockout/Tagout Required
  • Moving Machinery
  • Pinch Point
  • Crush Hazard
  • Hot Surface

Warning signs should be installed where employees encounter the hazard before exposure.

  • Pedestrian Crossing
  • Speed Limit
  • Loading Dock
  • Watch for Forklifts
  • No Riders on Forklifts

These signs help separate vehicle and pedestrian traffic and reduce workplace injuries.

  • Open Excavation
  • Crane Overhead
  • Danger – High Voltage

Common categories include:

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

Standardized signs help employees quickly recognize hazards.

Safety Sign Maintenance

Missouri employers should regularly inspect safety signs to ensure they remain:

  • Properly mounted
  • Undamaged
  • Appropriate for current workplace hazards
  • Replaced if faded or outdated

Regular inspections help maintain OSHA compliance and improve workplace safety.

  • Train employees on sign meanings.
  • Replace damaged or missing signs promptly.
