How to Identify and Mark Emergency Exits

How to Identify and Mark Emergency Exits is a critical skill for any employer, facility manager, or safety officer. Clearly marked and accessible emergency exits save lives during fires, power failures, chemical spills, and other emergencies.

According to the Occupational Safety and Health Administration (OSHA) (dofollow), blocked or poorly marked exits are among the top cited violations, leading to tragic outcomes during real emergencies.

Properly identifying and marking exits is not just about compliance—it’s about ensuring everyone can get out quickly and safely when seconds count.

Understanding the Basics of Emergency Exits

Before you can master how to identify and mark emergency exits, you need to know what qualifies as an emergency exit.

An emergency exit is:

• A permanent, unobstructed path to a safe area outside.
• Designed to handle expected occupant loads.
• Equipped with self-opening doors that swing in the direction of travel.
• Clearly marked and illuminated at all times.

Effective exits are simple, visible, and reliable, even in chaos.

How to Identify Emergency Exits in Your Facility

Step one in how to identify and mark emergency exits is figuring out where they are—and whether they meet safety requirements.

---

1. Review Building Plans

Start by reviewing architectural plans or fire safety blueprints.

• Locate all designed exits and evacuation routes.
• Confirm they lead to a public way or safe area.
• Check that they meet local building codes and occupancy load limits.

If your site has changed over time, verify that temporary walls or renovations haven’t blocked any exits.

---

2. Conduct a Physical Walkthrough

Plans aren’t enough—walk the site yourself.

• Look for actual doors marked as exits.
• Ensure doors open easily without keys or special knowledge.
• Check for obstructions in hallways, stairwells, or outside exit doors.
• Confirm adequate lighting along paths and at exit doors.

Tip: Do this regularly—workspaces change constantly!

---

3. Identify Alternate Exits

A single exit isn’t enough for most spaces.

• Ensure there are at least two exits for each area with high occupancy.
• Identify alternate routes if the main exit is blocked by fire or hazards.
• For large facilities, map multiple exit paths from different zones.

Alternate exits are critical for safe evacuation under unpredictable conditions.

---

4. Consider All Users

Think about everyone who might need to evacuate.

• Are routes accessible for wheelchair users?
• Can workers with limited mobility use the exits?
• Are exit paths wide enough for expected traffic?
• Are there areas of refuge in multi-story buildings if elevators can’t be used?

Inclusive planning saves lives.

How to Mark Emergency Exits Clearly

Once you’ve identified exits, the next step in how to identify and mark emergency exits is clear marking.

---

1. Install Standard Exit Signs

• Use recognized exit signs (typically green or red with white text).
• Signs must be illuminated at all times.
• If power fails, signs must have emergency lighting or battery backup.
• Place signs directly over or next to exit doors.

Signs must meet NFPA and local code requirements.

---

2. Use Directional Signs for Routes

Not every exit is immediately visible from every spot.

• Install directional arrows guiding people along routes.
• Mark corridors and junctions clearly.
• Place signs high on walls for visibility above crowds.
• Use consistent colors and symbols to reduce confusion.

Workers shouldn’t have to guess where to go.

---

3. Ensure Visibility in All Conditions

Emergencies often mean power loss or low visibility.

• Use photoluminescent (glow-in-the-dark) signs.
• Install battery-backed emergency lighting.
• Avoid clutter or decorations that block signage.
• Place lights to avoid shadows on signs or paths.

A sign that can’t be seen in smoke or darkness is useless.

---

4. Include Language and Symbol Support

Consider your workforce and visitors.

• Use universally recognized symbols (running man icon).
• Include multi-language signs if needed.
• Test comprehension with employees during drills.

Clarity prevents panic.

---

Maintaining and Inspecting Emergency Exits

Knowing how to identify and mark emergency exits also means keeping them usable at all times.

---

1. Conduct Regular Inspections

• Check exits monthly at minimum.
• Confirm doors open easily.
• Look for blocked paths (boxes, equipment).
• Test emergency lighting.
• Verify signage is intact and legible.

Use a checklist for consistency.

---

2. Train Employees

Even the best-marked exits are useless if workers don’t know how to use them.

• Include exit locations in new-hire orientations.
• Conduct evacuation drills at least annually.
• Review alternate routes during safety talks.
• Encourage questions and feedback.

Training builds confidence and speed during real emergencies.

---

3. Document Compliance

• Keep inspection logs.
• Record maintenance activities.
• Document drills and training sessions.
• Store records for audit and legal compliance.

Documentation proves due diligence and strengthens your safety program.

---

Special Considerations for Construction Sites

If you’re marking emergency exits on a construction site, extra care is needed.

• Update signage as site layout evolves.
• Use temporary signs and barriers to direct workers safely.
• Account for multi-level scaffolding and temporary stairs.
• Conduct daily safety huddles to review exit plans.

Benefits of Properly Identifying and Marking Emergency Exits

Following best practices for how to identify and mark emergency exits provides huge benefits:

• Faster, safer evacuations.
• Reduced injuries and fatalities in emergencies.
• Improved compliance with OSHA and local regulations.
• Stronger safety culture among workers.
• Reduced liability for employers.

Investing time in clear marking is low-cost insurance for everyone’s safety.

Final Thoughts on How to Identify and Mark Emergency Exits

Knowing how to identify and mark emergency exits is a fundamental responsibility for any employer or safety professional. It’s not a one-time project—it’s an ongoing commitment to keeping people safe every day.

By reviewing your facility, installing clear signage, maintaining exits, and training employees, you’ll build trust and readiness that truly saves lives.
