Parking lot fire regulations

The Fire Department has set a set of strict parking fire safety standards and regulations for the construction of parking lots, especially multi-storey parking lots. Builders are required to comply with all of these rules and regulations when constructing parking lots. These parking fire safety regulations can be divided into three main sections:

  • Parking lot design
  • Installing a fire detection and alarm system
  • Installing a fire extinguishing system

Each of these three sections must be examined separately. In addition, special standards have been established for parking lot ventilation. In the section on parking lot design, the subject of ventilation will be briefly discussed. In this review, we will mention some of the basic and important firefighting rules in parking lots. The main sources for this material are as follows:

  • Topic Three: National Building Regulations (Protection of Buildings Against Fire)
  • NFPA Standards

1. Parking lot fire regulations; design

Parking lot fire safety design requirements are divided into two parts: architecture and ventilation. Key points to consider include:

Parking architecture:

  • For better parking management, each floor should be divided into different sections or zones.
  • If the parking area is more than 2000 square meters, at least two exits must be provided at a certain distance, each equipped with stairs. It is necessary to use an elevator or escalator in at least one of these routes.
  • Parking lot exit points should be designed in a way that does not prevent smoke from returning to the parking lot.
  • When designing parking lots, a path should be considered for easy access for fire trucks to different sections. Special driveways should not be constructed to obstruct the movement of fire trucks.
  • The materials used in the construction of the parking lot must be fire resistant for at least one hour.
  • The width of the aisles for people to pass through must be at least 92 centimeters.
  • The distance between people from any parking spot to the nearest escape staircase should not exceed 120 meters.
  • The slope of the ramps must be less than 15% and the width of the ramps must be at least 3.5 meters.

Parking air conditioning:

  • Axial fans with an efficiency of over 80% are used for mechanical ventilation.
  • These fans must be fire-resistant and withstand temperatures of 300 degrees Celsius for at least one hour.
  • Ventilation systems should be equipped with carbon monoxide sensors so that if its concentration increases, the speed of smoke evacuation and fresh air intake can be increased. The concentration of carbon monoxide in the parking lot should not exceed 50 PPM over a period of 30 minutes.
  • The number of fans should be such that if half of them fail, the efficiency of the entire system will not fall below 50%.
  • The air velocity on each floor should not exceed 2 meters per second to prevent the rapid spread of fire.
  • Air ducts must be heat resistant up to 800 degrees Celsius.
  • The air speed inside the ducts should not exceed 12 meters per second.
  • Ventilation systems must be supported by emergency power.

2. Parking lot fire regulations; installation of a fire detection and alarm system

Installing fire detection and alarm systems in parking lots is very important in identifying fires in a timely manner. Typically, smoke detectors are not used in parking lots because high levels of pollution disrupt their operation. Therefore, heat detectors, which are highly sensitive to heat, are used.

Fire regulations for installing fire detection and alarm systems include:

  • Detectors should be installed in locations where airflow does not prevent timely fire detection. Therefore, detectors should not be installed along jet fans.
  • All system wiring must be resistant to heat of 900 degrees Celsius for at least 2 hours.

3. Parking lot fire regulations; installation of fire extinguishing system

Fire extinguishing is one of the fundamental issues in the construction of parking lots. We do not have to wait for the arrival of the fire brigade, but rather, we must take the necessary measures to extinguish the fire from the very beginning. This method is more effective and prevents financial and human losses. Fire extinguishing systems in parking lots are implemented in two ways: manual and automatic (sprinkler). Fire regulations must be observed for installing these systems in different parts of the parking lot.

Parking lot fire regulations standards

It is very important to comply with international and national standards in the field of parking lot fire regulations. These standards are based on scientific experience and research and include guidelines for the design, installation of fire detection and alarm systems, as well as fire extinguishing systems. Some of the most important standards related to parking lot fire regulations include:

NFPA (National Fire Protection Association) Standard: This standard is one of the most prominent and reputable international standards in the field of safety and firefighting, which is widely used in parking lots.
National Iranian Standards: These standards are also developed by relevant institutions in the country and pay special attention to local needs and conditions.

In addition to the design and installation of fire detection and extinguishing systems, parking lot fire regulations also include other items that must be considered. These include the use of fire-resistant materials, the installation of an emergency lighting system, and the use of clear emergency exit signs. Strict adherence to these principles can minimize the time it takes to evacuate the parking lot in critical situations and prevent the spread of fire.

Parking lot lighting standards

One of the fundamental issues in parking lot fire regulations and standards is the provision of adequate lighting. Parking lot lighting standards are of particular importance in ensuring the safety and comfort of people, especially in emergencies and when accidents occur. General principles and standards in this regard include the following:

Illuminance Level: In public parking lots, the level of illumination should be sufficient to allow people to move around safely and without any problems. This level of illumination should be increased at entrances, exits, and sensitive points such as corridors or stairs.

Uniform lighting coverage: Lighting should be distributed evenly throughout the parking lot to prevent unwanted shadows.

Emergency Lighting: Parking lots must be equipped with an emergency lighting system that activates automatically in the event of a power outage or an accident.

Lighting with the right color:
The use of white light or lights with a color temperature close to white (around 4000 Kelvin) is recommended to improve visual clarity and reduce eye fatigue.

Exit points and escape routes:
Emergency directional lights should be used around exit routes and strategic areas to clearly indicate the exit route in an emergency.

Proper installation of lights: Lights should be installed at an appropriate height and should not shine directly into people’s eyes. Also, these lights should be impact resistant so that they are not damaged in critical situations.

These standards may change depending on local laws and regulations and the specific needs of each project.

Use of fire-resistant materials in parking lots

In the construction of parking lots, materials must be used that are resistant to high temperatures and do not melt or become damaged in the event of a fire.

Solutions:

  • Using heat-resistant concrete to build walls and ceilings.
  • Using fireproof coatings to protect metal structures.
  • Designing ceilings and walls so that they can maintain their fire resistance for a long time.

For example, in some underground parking projects in Dubai, heat-resistant materials such as prestressed concrete and special coatings have been used to protect steel structures so that the structures can maintain their fire resistance in the event of a fire.

Safe exit routes from the parking lot

One of the most important aspects of parking lot fire regulations is the provision of safe and convenient exit routes for vehicles and people. In the event of a fire, people must be able to exit the parking lot quickly and without hindrance. Therefore, it is essential to observe the following points:

  • Designing exit routes with appropriate width for vehicle passage.
  • Installing fire doors to prevent fire from spreading to other parts.
  • Use of directional signs and emergency lighting systems to facilitate rapid evacuation of people.

Firefighting equipment in the parking lot

The presence of appropriate firefighting equipment in parking lots is vital and cannot be overlooked. This equipment should be designed in such a way that in the event of a fire, fire extinguishing operations can be carried out quickly and efficiently. Some of the most important firefighting equipment that should be installed in parking lots include:

Fire extinguishers: These extinguishers should be placed at key and strategic points in the parking lot so that they are quickly accessible in the event of an initial fire.
Sprinkler systems: In large or underground parking lots, sprinkler systems are essential to combat fires. These systems are activated automatically upon detection of high heat and spray water to extinguish the fire.
Fire alarm systems: Installing fire alarm systems, including smoke and heat detectors, in parking lots helps to quickly detect a fire and prevent it from spreading.
