TL;DR

OSHA's exit route standard (29 CFR 1910.34 through 1910.37) applies to nearly every employer, with no small-business exemption. You need at least two exit routes in most workplaces, a minimum 28-inch clear width, illuminated exit signs, and a written emergency action plan if you have more than 10 employees. Serious violations run up to $16,131 each as of January 2024.

What OSHA rules actually govern exit routes?

The core standard is 29 CFR 1910.34 through 1910.37, which OSHA groups under Subpart E, "Exit Routes." These four sections replaced the older NFPA Life Safety Code reference OSHA used before its 2002 rulemaking, and they apply to "all workplaces in general industry" regardless of size. [11] There is no small-business exemption. None.

Three sections do most of the work. Section 1910.36 covers the design and construction of exit routes. Section 1910.37 covers maintenance, safeguards, and operational features. Section 1910.38 covers emergency action plans, the written document requirement. OSHA treats these as closely related requirements and compliance officers inspect them together during a walkthrough. [2]

If your state runs an OSHA-approved State Plan (California, Michigan, Washington, and 19 others), the state standard must be "at least as effective" as the federal rule, and most states adopt the federal text word for word. [3] Check your state plan before you assume anything is different.

How many exit routes does my business need?

The default under 29 CFR 1910.36(b)(1) is at least two exit routes. A single exit is allowed only when the workplace is small enough and the occupant load low enough that one exit does not raise the risk, and OSHA gives you no specific headcount number to hang your hat on. The standard says a single exit may work "if the number of employees, the size of the building, its occupancy, or the arrangement of the workplace is such that all employees would be able to evacuate safely." [1] In practice, compliance officers rarely accept a single exit for any occupied commercial space unless it is genuinely a one-room office with a door to the outside.

Three or more exits become required whenever a single route exposes workers to "increased risk from fire or other emergency." High-hazard processes, large floor plates, and complex layouts all push you toward three. The National Fire Protection Association's Life Safety Code (NFPA 101) uses similar logic and adds occupant-load tables that OSHA's standard does not mandate on its own.

Here is the rule of thumb most safety professionals use: if any employee has to travel more than 200 feet to reach an exit, you almost certainly need more than two. OSHA's standard sets no maximum travel distance number, but the agency's letters of interpretation consistently flag long travel distances as a hazard. [4]

What are the minimum size and clearance requirements for exit routes?

The minimum clear width of an exit access (the path leading to an exit) is 28 inches under 29 CFR 1910.36(g). [1] That is 28 inches of unobstructed space, floor to ceiling. Shelving, equipment, boxes, or pallets that eat into that width are a citation waiting to happen.

The exit itself (the door, corridor, or passage that leads directly outside or to an exit discharge) has a minimum height of 7 feet 6 inches and a minimum width of 28 inches. If powered industrial trucks or any wheeled equipment move through the space, the route has to fit them plus the 28-inch minimum, which in practice means a much wider corridor.

Doors that serve as exits must swing in the direction of travel when the room holds 50 or more occupants or contains a high-hazard area. [1] Sliding doors, revolving doors, and roll-up doors cannot serve as required exits. That one catches older warehouse setups off guard.

What are the exit sign and lighting requirements?

Every exit must be marked with a sign reading "Exit" in plainly legible letters under 29 CFR 1910.37(b). [2] That sounds obvious until you notice the standard also requires directional signs along the path to each exit. Stand anywhere in your workplace. If you cannot see an exit sign from that spot, OSHA wants an intermediate sign with an arrow pointing the way out. This is the most commonly missed piece in small retail and warehouse spaces.

The exit sign has to stand out from every other sign around it, and it cannot be, in OSHA's words, decorated, obscured, or concealed. So no stacking inventory in front of it. No hanging a promo banner that clips the corner. Both show up in real citations.

Lighting lives at 29 CFR 1910.37(b). Exit routes must be lit whenever the workplace is occupied, bright enough that a worker with normal vision can find the way out. OSHA does not fix a lux value in the 1910.37 text, but the agency has leaned on NFPA 101's benchmark of 1 foot-candle at floor level during enforcement. [4] Emergency backup lighting has to switch on automatically if the primary system fails and last long enough for a full evacuation.

Battery-backed LED exit signs (the ones with the built-in battery) cover both the sign and the emergency lighting requirement in a single unit. They run roughly $30 to $80 each from commercial suppliers. It is one of the cheapest compliance items you will ever buy, so buy the good ones.

What is a written emergency action plan and when is it required?

An Emergency Action Plan (EAP) is required under 29 CFR 1910.38 for any employer covered by a standard that calls for one, and separately for any employer with more than 10 employees. [5] With 10 or fewer employees, OSHA lets you communicate the EAP out loud instead of in writing, though a written version is the safer bet and costs you nothing.

The required elements of a written EAP under 1910.38(c) are specific:

  • Procedures for reporting a fire or other emergency
  • Procedures for emergency evacuation, including type of evacuation and exit route assignments
  • Procedures for employees who must stay to operate critical plant operations before evacuating
  • Procedures to account for all employees after evacuation
  • Procedures for employees performing rescue or medical duties
  • The name or job title of every employee who may be contacted for more information about the plan

You also have to designate and train employees to assist in evacuation under 1910.38(e). This does not mean a fire brigade. It means someone on site knows the plan, knows who has mobility limitations, and knows how to steer people to the right exit.

The EAP has to stay at the workplace and be available to employees on request. [5] If you are building yours from scratch, SafetyFolio's safety program generator walks you through the required elements in about 15 minutes and produces a document formatted for a compliance inspection.

What counts as an "exit" versus an "exit access" or "exit discharge"?

OSHA uses three precise terms and each one matters for compliance.

Exit access is the part of an exit route that leads to an exit. Your office hallway, your warehouse aisle, the path between workstations: all exit access. Keep it clear and marked.

Exit is the part of an exit route separated from other areas to give a protected path to the exit discharge. Picture a stairwell walled off with fire-rated construction, or a door that opens straight to the outside. Under 29 CFR 1910.36(a), the exit must be separated from the rest of the workplace by materials that resist fire for at least one hour, or two hours if the building is four or more stories. [1]

Exit discharge is the part of the exit route between the exit and the outside of the building. A vestibule, a covered walkway, a stairway landing beyond the door: all exit discharge.

Why does this matter? Because inspectors check each segment on its own. You can have a clearly marked exit door that opens into a blocked or dimly lit discharge area, and that is still a violation even though the door itself is fine.

What can and cannot be stored or placed in exit routes?

Nothing. That is the short version.

29 CFR 1910.37(a)(3) states plainly: "Exit routes must be free and unobstructed. No materials or equipment may be placed, either permanently or temporarily, within the exit route." [2] Seasonal inventory overflow, extra furniture, compressed gas cylinders parked "just for now," charging forklifts, extension cords run across the path. All prohibited.

Blocked and obstructed exits rank among the most common general industry citations year after year. OSHA's enforcement data show exit and egress violations landing in the top-cited standards consistently. [6] For small retail in particular, blocked exits and locked or chained exit doors are a repeat offense.

Locked exit doors get their own line at 29 CFR 1910.36(d): exit doors must stay unlocked from the inside at all times when the workplace is occupied. Padlocks, chains, and doors that need a key to get out are direct violations and real life-safety hazards. There is zero ambiguity here and no theft-worry exception for small businesses.

If you legitimately need to control who comes in, use one-way exit hardware: a crash bar on the inside for free exit, a key reader or keypad on the outside for controlled entry. That covers security without locking your people in.

How often do exit routes need to be inspected and tested?

OSHA's standard at 29 CFR 1910.37(a)(3) and (b) requires exit routes to stay passable and all required features (signs, lighting, door hardware) to stay functional. [2] OSHA does not name a frequency, which sounds like a loophole and is not. If an inspector finds a dead exit sign or a blocked aisle, "the rule never said how often" is not a defense.

The practical standard, recommended by most safety consultants and reflected in NFPA 101, is a monthly visual inspection of every exit route plus an annual functional test of emergency lighting. Keep a simple log. A one-page spreadsheet with date, inspector name, and any items found and corrected is enough documentation.

Emergency action plan training is a separate matter. OSHA requires you to train employees on the EAP when it is developed, when an employee's responsibilities under it change, and when the plan itself changes, under 1910.38(f). [5] The standard sets no specific annual drill frequency for most general industry employers, though regular drills are obviously smart and some state plans do require them.

For fire brigades and fire prevention plans, if your workplace has those, 29 CFR 1910.156 and 1910.39 add requirements beyond basic exit routes.

What are the penalties for exit route violations and how does OSHA classify them?

OSHA classifies most exit route violations as "serious" because a blocked or locked exit ties directly to potential serious injury or death. [7] As of January 2024, the maximum penalty for a serious violation is $16,131 per violation. Willful or repeated violations reach $161,323 per violation. [7]

Penalties get adjusted for severity, probability, employer size, good faith, and prior history. Small employers (fewer than 250 employees) typically see a 60 to 80 percent reduction off the maximum, but OSHA can and does cite small businesses at full value when there are prior violations or when the hazard is severe, like a chained exit door in an occupied store.

Here is the part that gets people's attention: OSHA also uses "instance-by-instance" citation authority for egregious cases, meaning each obstructed exit door can be cited on its own. A warehouse with four blocked exits could face four separate citations instead of one. [9] Multiply $16,131 by four and the math stops being abstract.

OSHA's news release archive documents six-figure aggregate penalties in multi-location retail cases involving blocked exits. [8] These are real dollar amounts from real enforcement actions, not hypotheticals.

Do exit route requirements differ for specific industries like retail, warehouses, or offices?

The same 29 CFR 1910.34 through 1910.38 framework applies across general industry. The practical headaches just differ by setting.

Retail carries the highest risk of blocked exits from seasonal stocking and the highest risk of locked exits from theft prevention. OSHA inspections in retail flag both again and again. If you run a store, the exit door behind the stockroom counter and the fire door propped open with a box are your two biggest citation risks.

Warehouses and distribution centers wrestle with travel distance and forklift obstruction. Racking that crowds exit doors, forklifts parked in exit aisles, pallets staged near exits: all frequent in warehouse citations. The 28-inch minimum clearance is the number that gets warehouses cited most.

Offices look low-risk and are not. Furniture rearrangements block exit paths. Locked stairwell re-entry doors (legal under fire codes but often confused with locking the stairwell exit itself) cause panic. Tenant build-outs leave exit signs in the wrong spots.

Construction, maritime, and agriculture have their own OSHA standards, with 29 CFR 1926 covering construction egress. If you run both a fixed establishment and a construction component, each falls under its own subpart.

For how OSHA structures its requirements across industries, and for related life-safety topics like lockout tagout and hazard communication, those standards touch exit route planning in any facility handling chemicals or energized equipment.

What does an exit route compliance checklist look like for a small business?

You do not need a consultant for this audit. Walk your facility with the framework below and write down what you find.

Number and location of exits. Do you have at least two exits? Are they on opposite sides of the building, not both on the same wall? Can every employee reach an exit without a long trek across the floor?

Door hardware. Do all exit doors swing in the direction of travel (if 50-plus occupants or high-hazard)? Do they open from the inside without a key, special knowledge, or more than a single push? No padlocks. No chains. No keypad-only exits.

Width and height. Walk the exit access routes with a tape measure if you have any doubt. 28-inch minimum clear width the whole length. 7-foot-6-inch minimum ceiling height through the exit.

Signs. Is every exit door marked with an "Exit" sign? Can you see an exit sign or a directional sign from every point in the workplace? Are all signs illuminated or self-luminous?

Lighting. Is the exit route lit? Does emergency backup lighting exist, and does it kick on when you cut the power to test it?

Obstructions. Is the full width of every exit route clear? Right now? Check again after your next delivery.

Emergency action plan. Do you have one if you have more than 10 employees? Does it carry all six required elements from 29 CFR 1910.38(c)? Have employees been trained on it?

Inspection log. Is someone checking these items monthly and writing it down?

If you want to turn this checklist into a compliant written program fast, SafetyFolio's safety program generator covers the EAP requirements and produces the documentation compliance officers expect to see.

For how inspections work and what officers look for, the incident report process and basic OSHA training requirements are worth reading alongside exit route compliance.

Frequently asked questions

Does OSHA's exit route standard apply to businesses with fewer than 10 employees?

Yes. 29 CFR 1910.34 through 1910.37 apply to all general industry employers regardless of size. The only provision that scales with employee count is the Emergency Action Plan: employers with 10 or fewer employees may communicate the EAP orally instead of in writing under 29 CFR 1910.38(b). Every physical requirement for exit routes applies no matter your headcount.

Can I use a sliding door or a roll-up door as an exit?

No. OSHA's standard at 29 CFR 1910.36(d) prohibits sliding doors, revolving doors, and roll-up doors from serving as required exits. Required exits must be side-hinged or pivoting swinging doors. You can have a sliding door elsewhere, but it cannot count toward your required number of exits.

What is the maximum travel distance to an exit that OSHA allows?

OSHA's 29 CFR 1910.36 sets no specific maximum travel distance number. Its letters of interpretation treat excessive travel distances as a hazard, and enforcement has relied on NFPA 101 benchmarks in some cases. Most safety professionals use 200 feet as a practical ceiling for low-hazard spaces and much less for high-hazard environments.

How many emergency exit signs does my small business need?

You need one sign at every exit door, plus directional signs at every point where the nearest exit is not immediately visible. OSHA's standard at 29 CFR 1910.37(b) requires exits to be marked by a sign reading Exit. There is no fixed number per square foot. Walk your space: if you cannot see an exit sign from a given spot, you need a directional sign there.

What happens if my exit door is blocked during an OSHA inspection?

A blocked exit is typically cited as a serious violation under 29 CFR 1910.37(a)(3). As of 2024, serious violations carry a maximum penalty of $16,131 each, though small employers usually get a reduction. If multiple exits are blocked, each can be cited separately under OSHA's instance-by-instance citation authority, multiplying the potential penalty fast.

Do I need an emergency action plan if I have fewer than 10 employees?

You are required to have one, but OSHA lets you communicate it verbally rather than in writing if you have 10 or fewer employees under 29 CFR 1910.38(b). The plan still has to cover all required elements: evacuation procedures, exit assignments, employee accounting, and emergency contact information. A written version regardless is the safer approach and costs nothing.

How do exit route requirements interact with fire codes?

OSHA's standard and local fire codes (usually based on NFPA 101 or the International Fire Code) overlap heavily. OSHA enforces its standard at the federal level; your local fire marshal enforces fire codes at the building level. You can pass one and fail the other. NFPA 101 adds occupant-load tables and travel distance limits OSHA references but does not fully adopt, so check both.

Can I lock an exit door if I'm worried about theft or unauthorized entry?

No. 29 CFR 1910.36(d) requires exit doors to be unlocked from the inside whenever the workplace is occupied. There are no exceptions for security. If you need to control entry, install hardware with a crash bar on the inside (free exit) and a key reader or keypad on the outside (controlled entry). That satisfies both security and OSHA.

How often does OSHA require exit route drills or testing?

OSHA sets no specific annual drill frequency for most general industry employers. The standard requires emergency action plan training when the plan is developed, when an employee's responsibilities change, and when the plan itself changes. Physical exit route features must stay functional under 29 CFR 1910.37. Monthly visual checks and annual emergency lighting tests are the accepted industry practice.

What fire separation is required for an enclosed exit stairwell?

Under 29 CFR 1910.36(a), exit routes must be separated from other building areas by materials that resist fire for at least one hour if the building has fewer than four stories, or at least two hours if four or more stories. Self-closing fire doors with the right rating are required. Propping these doors open defeats the purpose and is a separate violation.

Are there exit route requirements for temporary workplaces or mobile operations?

General industry exit route requirements apply to any fixed establishment. For construction sites, 29 CFR 1926 Subpart F covers fire protection including egress, with requirements scaled to the work. Temporary office trailers on job sites fall under 29 CFR 1910 if they qualify as a workplace. When in doubt, apply the general industry standard.

What documentation do I need to show an OSHA inspector for exit routes?

At minimum: a written Emergency Action Plan (if you have more than 10 employees), training records showing employees were trained on it, and inspection logs showing regular exit route checks. Inspectors will also walk the routes, test door hardware, and verify sign illumination. Documentation alone does not satisfy the standard; the routes have to actually be compliant.

Do exit route rules change if my business is in a state with its own OSHA plan?

State Plan states must keep standards at least as effective as the federal OSHA standard, and most adopt the federal text verbatim. A few, like California (Cal/OSHA), add requirements or use slightly different enforcement thresholds. Check your specific state plan at osha.gov/stateplans. The federal 29 CFR 1910.34 through 1910.38 framework is the safe baseline everywhere.
