Fire Department Access & Hydrants

When a fire starts, firefighters need to reach the building and find water quickly. Parked cars in a fire lane, a snow bank on a hydrant, a locked gate, or a trailer parked against a sprinkler connection can add precious minutes. Keeping access clear is simple and can save lives and property.

What fire crews need

• Roads and lanes wide and strong enough for fire apparatus to reach buildings. The International Fire Code (IFC) generally calls for fire apparatus access roads at least 20 feet wide with an unobstructed clear height of at least 13 feet 6 inches, able to support heavy trucks, with turning radii and dead-end turnarounds. Local codes may differ. See International Fire Code and Building Codes.
• Fire lanes: marked areas (curbs painted red, signs saying NO PARKING FIRE LANE) kept clear at all times.
• Hydrants and water supply: clear access to fire hydrants and other water sources. Many codes require a clear space of at least 3 feet around a hydrant, and visible and reachable from the road, with sign or marker where needed.
• Fire department connections (FDCs): the pipe connections where firefighters pump water into a building's sprinkler or standpipe system. They must be visible, accessible and not blocked by landscaping, fences, vehicles or storage. See NFPA Sprinkler Standards.
• Building access: doors, stairs and roof access that firefighters can use, plus gates, barriers and security systems with a way for them to get through.
• Key boxes (Knox-Box or similar): a lockbox on the building with keys and access cards that fire crews can open with a master key, so they don't have to break doors.
• Information: building plans, hazardous materials lists, emergency contacts and alarm panel instructions available for responders at a known location.

What not to do

• Don't park, even briefly, in a fire lane, in front of a hydrant, across an FDC or in an area that narrows the road. Delivery drivers and rideshare drivers are often the culprits. Don't leave equipment, dumpsters or trailers in fire lanes. See Last-Mile Delivery and Truck Parking.
• Don't block hydrants with snow, vehicles, dumpsters, landscaping, fencing or construction materials. Clear snow from hydrants near you. See Winter Storms at Home.
• Don't lock gates or chain doors without giving the fire department a way to enter, such as a key box, a padlock and master key or a gate override device.
• Don't add speed bumps, planters, barriers or low-hanging trees that block or damage the clear width and height of fire lanes.
• Don't block exits or stairwells inside, since firefighters use them too. See Exit Routes.
• Don't tamper with hydrants. Only authorized people may open them. See Excavation & Right-of-Way Permits for hydrant use permits.

Construction and renovation sites

• Fire codes require fire department access and water supply at construction sites, often before combustible materials are brought on site, with fire lanes, hydrants and signs kept open as the building grows. Check IFC Chapter 33 and the local rules.
• Provide site access for fire trucks during construction with surfaces that can bear their weight in all weather, and keep material, dumpsters and temporary buildings away from access lanes, hydrants and FDCs.
• Keep hydrants and standpipes working and accessible. Install and keep clear the temporary or permanent standpipes as the building rises.
• Post site addresses, contact lists and emergency plans, and give responders a way through gates and fences. See Emergency Action Plans.
• Control hot work and combustible storage. See Hot Work Permits and Fire Prevention.
• Tell the fire department about the project and any hazards, and invite them for a pre-incident walkthrough.

What owners and managers can do

• Mark and sign fire lanes properly and enforce no parking. Ask the local fire marshal or police for help.
• Inspect hydrants, FDCs and key boxes regularly and keep them clear of snow, plants and storage. Report problem hydrants to the water utility.
• Provide a key box with current keys and access cards, and update it when locks change.
• Keep addresses visible from the street and building numbers on doors and rooftops where needed.
• Arrange pre-incident plans and tours for the fire department, and tell them about special hazards. See Fire System Impairments when systems are out of service.
• Train staff and tenants and write access rules in leases and contracts. See Apartment Fire Safety.

If you see blocked access

• Report blocked fire lanes and hydrants to the property manager, the local fire department or police non-emergency line. Many cities issue tickets and towing.
• If a fire is happening now, call 911 and move your vehicle if you can do so safely, leaving keys with the vehicle or a responsible person, since firefighters may have to move or damage it.
• Don't park near fire scenes or cross hose lines with a vehicle.

Fire access checklist

• Fire lanes are marked, clear and wide and tall enough for apparatus
• Hydrants have at least 3 feet clear and are free of snow, plants and parked vehicles
• Fire department connections are visible and accessible
• Gates and secure doors can be opened by firefighters, and a key box is updated
• Construction sites keep access and water supply open as the work progresses
