This blog post aims to provide comprehensive information about emergency exit route requirements in the workplace. We will explore the significance of having well-designed exit routes, the number of exit routes necessary, and the specific regulations and guidelines that must be followed. Additionally, we will highlight the benefits of complying with these requirements, including improved employee confidence, enhanced emergency preparedness, and compliance with legal regulations.

By familiarizing ourselves with the necessary steps to establish and maintain proper emergency exit routes, employers and employees can work together to ensure a safe and secure working environment. Let’s delve into the details of emergency exit route requirements to create a workplace where safety is a top priority.

Emergency Exit Route

What Is An Exit Route?

An exit route, also known as an emergency escape route, is a designated pathway from any location in a workplace leading directly to a secure area outside. This pathway is designed to be free of obstructions to facilitate safe evacuation during emergencies. The exit route comprises three main sections:

  • Exit Access: This is the segment of the exit route that guides individuals toward an exit.
  • Exit: This part, usually isolated from the rest of the workspace, offers a secure passage towards the exit discharge.
  • Exit Discharge: This final section of the exit route takes individuals directly outdoors or to an open area, public pathway, emergency assembly point, or other spaces with unrestricted outdoor access.

How many exit routes must a workplace have?

Under normal circumstances, a workplace must maintain at least two escape routes to ensure quick and efficient evacuation of employees and other occupants in an emergency. However, if the employee count, workplace size, or layout prevents safe evacuation, more than two exits may be required. Ideally, these exit paths should be spaced as far apart as possible to cater to situations where one may be obstructed by fire or smoke.

There’s an exception to this rule: if the building size, number of employees, occupancy rate, or the setup of the workplace guarantees a safe evacuation for all in an emergency, a single exit route can be considered sufficient.

Importance of Having Emergency Exit Routes

Having well-designed and properly maintained emergency exit routes in the workplace is of utmost importance for several reasons:

  • Life Safety: The primary purpose of emergency exit routes is to ensure the safety and well-being of employees during emergencies. They provide a clear and direct path for evacuation, reducing the risk of injury or loss of life in critical situations such as fires, natural disasters, or other hazardous incidents.
  • Rapid Evacuation: Emergency exit routes enable a swift and efficient evacuation process. Every second counts in emergencies, and having clearly marked exit routes helps individuals find the nearest and safest way to exit the building quickly.
  • Prevention of Panic and Congestion: Properly designed exit routes can help prevent panic and congestion during an evacuation. Clear signage and unobstructed pathways guide employees to safety, minimizing the chances of overcrowding or bottlenecking that can impede evacuation efforts.
  • Compliance with Regulations: Many jurisdictions have strict regulations and building codes that mandate the presence of emergency exit routes in workplaces. Complying with these regulations ensures legal and regulatory compliance, protecting employees and the organization from potential penalties or legal liabilities.
  • Employee Confidence and Peace of Mind: Knowing that there are well-planned and accessible exit routes in the workplace instills a sense of confidence and peace of mind among employees. It enhances their overall safety perception and fosters a positive work environment.
  • Rescue and Emergency Response: Emergency exit routes also facilitate the work of rescue personnel and emergency responders. Clear and easily identifiable routes enable them to locate and assist individuals more efficiently during emergencies, potentially reducing the severity of injuries and improving overall response time.
  • Training and Preparedness: Exit routes are important components of emergency preparedness and training programs. By familiarizing employees with the location and use of exit routes, organizations can conduct effective evacuation drills, emergency response training, and communication protocols, enhancing overall preparedness in an emergency.

In summary, having well-planned, properly marked, and easily accessible emergency exit routes is essential for the safety and well-being of employees, compliance with regulations, and effective emergency response in the workplace.

Exit Routes Requirements

Emergency Exit Route Requirements In The Workplace

Workplace safety regulations such as those in the United States established by the Occupational Safety and Health Administration (OSHA) provide guidelines for emergency exit routes to ensure employees can quickly and safely evacuate in case of an emergency. Below are some key requirements:

  • Permanence: Exit routes must be a permanent part of the workplace. They should not be subject to change or relocation, ensuring all employees’ familiarity and ease of access.
  • Direct Access to Outdoors: The exit routes must lead directly to the outside or to a street, walkway, refuge area, public way, or open space with access to the outside. The area immediately outside the exit, referred to as the exit discharge, must be sufficiently large to accommodate the anticipated number of evacuees.
  • Exit Indicators: If exit stairs extend beyond the level of the exit discharge, there should be doors, partitions, or other clear indicators at that level to direct individuals toward the exit.
  • Unlocked Exit Doors: Doors along the exit route must be unlocked from the inside. These doors should not be equipped with devices or alarms that could restrict use in the event of a malfunction.
  • Door Type and Direction: Rooms connected to exit routes should feature side-hinged doors. If a room is designed to hold more than 50 people or is considered a high-risk area, these doors should swing toward the exit.
  • Capacity: Exit routes must be able to accommodate the maximum allowed number of occupants for each floor. Also, the capacity of the exit route should not decrease in the direction of moving toward the exit discharge.
  • Ceiling Height: The ceiling height of exit routes should not be less than 7 feet or 6 inches.
  • Width: At all points, the width of exit routes should not be less than 28 inches. In instances where there is only one exit, the width of the exit and the exit discharge must be at least as wide as the exit access.
  • Outdoor Exit Routes: Outdoor exit routes can be used but must comply with the same height and width requirements as indoor routes. If there’s a risk of falling, they should have guardrails. They should be covered if snow or ice accumulation is a potential issue. The walkways of these routes should be straight, smooth, and level. Dead-ends on these outdoor routes must not exceed 20 feet in length.
  • Number of Exit Routes: A minimum of two exit routes must be available in case one is blocked. The number might increase depending on the number of employees, the size of the building, and the arrangement of the workplace.
  • Exit Discharge: Exits must lead directly outside or to a street, walkway, refuge area, or open space with access to the outside. These exit discharge areas must be large enough to accommodate the building occupants likely to use the exit route.
  • Door Swing: Exit doors must swing out in the direction of exit travel if the room is to be occupied by more than 50 people or the exit is a high-hazard area.
  • Construction: Exit routes must be fire-resistant and have self-closing fire doors. They must be free of decorations or signs that obscure visibility.
  • Capacity and Dimension: Exit routes must support the maximum permitted occupant load for each floor served, and the ceiling of an exit route must be at least 7 feet, 6 inches high. An exit access must be at least 28 inches wide.
  • Accessibility: Exit routes must be free of obstructions and adequately lit, with signs clearly marking the exit. They cannot be blocked by any locked doors that impede emergency evacuation.
  • Maintenance: Exit routes should be maintained safely and clear of explosive or hazardous materials.
  • Training and Communication: Employees should be informed and trained about the types and locations of emergency exits. Exit routes must be visibly signposted and identifiable with appropriate signage.
Emergency Exit Route Requirements

The three main points of an exit route are:

  • Exit Access: This refers to the segment of the exit route that guides individuals toward an exit. It includes hallways, corridors, aisles, or any other means of reaching the exit.
  • Exit: The exit itself is a designated area that provides a secure passage to individuals seeking to evacuate. It is typically separated from the rest of the workspace to ensure a clear path to safety.
  • Exit Discharge: The exit discharge is the final section of the exit route that leads individuals directly outdoors or to an open area with unrestricted outdoor access. It may be a street, walkway, emergency assembly point, or any other space that provides a safe exit from the building.

Exit routes must meet specific requirements to ensure individuals’ safety and efficient evacuation. The minimum height of an exit route’s ceiling should be at least seven feet six inches (2.3 meters). Any object or structure extending from the ceiling must maintain a minimum clearance of six feet eight inches (2.0 meters) from the floor to allow free movement.

Similarly, the width of an exit route is crucial. It should be wide enough to accommodate the maximum number of people on each floor. At any point, the width of the exit route must not be less than 28 inches (71 centimeters). If there is only one exit route, the exit access and discharge must be as wide as the exit itself.

Escape routes, also known as evacuation or emergency escape routes, are designated pathways or routes that allow people to safely exit a building or area during an emergency or hazardous situation. These routes are carefully planned and established to ensure the quick and efficient evacuation of individuals to a place of safety.

Emergency exits are typically located strategically throughout a building, such as stairwells, hallways, or other easily accessible areas. These exits are marked with clear signage and often feature outward-opening doors equipped with crash bars or other easy-to-operate mechanisms. The exit signs leading to these emergency exits serve as visual cues, guiding individuals toward the nearest and safest way out of the building during emergencies.

Exit signs can be categorized into two main types: incandescent and photoluminescent. Incandescent exit signs utilize light bulbs to provide illumination and make the sign visible. On the other hand, photoluminescent exit signs employ a special material that absorbs and stores light energy during normal lighting conditions and releases it in the form of a glow during darkness or low-light situations, ensuring the sign remains visible even without a direct power source.


Ensuring the presence of well-designed and properly maintained emergency exit routes in the workplace is crucial for the safety and well-being of employees. Complying with regulations, conducting regular training, and prioritizing maintenance protect lives, fosters a positive work environment, enhances emergency preparedness, and ensures compliance with legal requirements. Employers demonstrate their commitment to employee safety and create a resilient workplace by prioritizing establishing and maintaining effective emergency exit routes.
