Pennsylvania OSHA Signs Required in the Workplace

Maintaining proper workplace safety signage is an important part of OSHA compliance. While OSHA does not require every business to display the same safety signs, employers must post signs, labels, and warnings whenever workplace hazards exist or specific OSHA standards require them. Proper signage helps communicate hazards, direct employees during emergencies, identify required protective equipment, and reduce workplace injuries.

Most private employers in Pennsylvania are covered by federal OSHA requirements. Depending on the workplace, employers may also need to comply with Pennsylvania-specific posting requirements, including certain notices under the Worker and Community Right to Know Act.

This guide explains many of the common OSHA-related safety signs Pennsylvania employers may need.

OSHA Job Safety and Health Poster

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

The poster explains employee rights and employer responsibilities under the Occupational Safety and Health Act.

The OSHA poster should be:

  • Displayed in a conspicuous location.
  • Accessible to all employees.
  • Kept readable and undamaged.
  • Displayed alongside other required workplace notices when appropriate.

Exit Signs

Employers should clearly identify emergency exits.

Common exit signage includes:

  • EXIT signs.
  • Emergency exit route signs.
  • Exit direction arrows.
  • Emergency evacuation maps where appropriate.

Exit signs should remain visible, illuminated when required, and unobstructed.

Fire Safety Signs

Many workplaces should display fire protection signage such as:

  • Fire extinguisher location signs.
  • Fire alarm pull station signs.
  • Fire hose cabinet signs.
  • Fire exit signs.
  • Emergency assembly point signs.

Proper fire safety signage helps employees respond quickly during emergencies.

Personal Protective Equipment (PPE) Signs

Where PPE is required, employers should clearly notify employees.

Common PPE signs include:

  • Eye protection required.
  • Hearing protection required.
  • Hard hats required.
  • Safety footwear required.
  • Respirator required.
  • Face shield required.
  • Protective gloves required.
  • High-visibility clothing required.

These signs remind employees of required protective equipment before entering hazardous work areas.

Hazard Warning Signs

Employers should identify hazardous areas with appropriate warning signs.

Examples include:

  • Warning – High Voltage.
  • Danger – Authorized Personnel Only.
  • Forklift Traffic.
  • Chemical Storage Area.
  • Hot Surface.
  • Confined Space.
  • Fall Hazard.
  • Slippery When Wet.

The wording and design should clearly communicate the specific hazard.

Hazard Communication Labels

Employers using hazardous chemicals must properly label chemical containers and maintain Safety Data Sheets (SDSs).

Hazard communication typically includes:

  • Chemical identification.
  • Hazard pictograms.
  • Signal words.
  • Precautionary statements.
  • Employee access to SDSs.

Proper labeling is an important part of OSHA's Hazard Communication Standard.

Equipment Safety Signs

Many employers also use equipment-specific safety signs such as:

  • Lockout/Tagout notices.
  • Machine guarding warnings.
  • Electrical panel warnings.
  • Emergency shutoff instructions.
  • Crane operation warnings.
  • Welding safety signs.
  • Laser warning signs.
  • Biohazard signs where applicable.

These signs should be located near the equipment or hazard they identify.

Facility Safety Signs

Additional workplace safety signs may include:

  • First Aid Station.
  • AED Location.
  • Emergency Shower.
  • Eyewash Station.
  • No Smoking.
  • Authorized Personnel Only.
  • Visitor Check-In.
  • Emergency Contact Information.

Proper facility signage helps employees quickly locate important emergency resources.

Employer Best Practices

Pennsylvania employers should:

  • Conduct regular workplace safety inspections.
  • Replace damaged or faded safety signs.
  • Ensure required OSHA posters remain displayed.
  • Install hazard signs wherever workplace hazards exist.
  • Review safety signage whenever equipment or operations change.
  • Train employees on the meaning of workplace safety signs.
