Emergency Lighting for Warehouses

Warehouses are practically mazes. Tall racking, stacked pallets, loading bays, and busy walkways spread across a large space. Imagine being inside one when the power suddenly fails and no emergency lights come on. Forget finding the exit right away.

Add forklifts, moving equipment, and people unfamiliar with the building to the equation, and a simple power cut becomes a safety concern. This is why emergency lighting for warehouses matters. It helps people navigate escape routes, identify potential hazards, and leave the building safely during power failures.

In this guide, we’ll explore everything you need to know about warehouse emergency lighting, so that by the end you’ll know how to effectively plan a system that works when everything else fails.

Why Emergency Lighting Is Essential in Warehouses

You can’t compare warehouses to office spaces. Unlike a typical office, a warehouse may contain high storage racks, narrow aisles, raised loading platforms, and areas filled with machinery or moving goods. In other words, evacuation can be more complicated when the main lighting supply fails.

Even long-time employees can struggle to find the exit in the darkness during a sudden power cut. Imagine what it would be like for visiting delivery drivers, contractors, and temporary workers! Poor visibility can make it harder to spot pallet trucks, obstacles, floor-level changes and equipment left in walkways. Moving equipment and people can also suddenly be in danger.

Emergency lighting doesn’t replace normal lighting, but it can help people move safely toward exits and reduce confusion and safety risks when the power suddenly fails. Combine that with clear escape routes, signage, and a strong safety plan, and emergency lighting really shines. Quite literally too!

This means that a well-planned system reflects how the warehouse actually operates, not simply how it looks on a floor plan.

Where Is Emergency Lighting Needed in a Warehouse?

This varies depending on the warehouse. Specifically, consider the warehouse size, layout, activities, and fire risk assessment. In general, consider these main areas:

Storage Aisles and High-Racking Areas

Do you know what warehouses have in common? Tall shelving and stacked pallets. These can block sightlines, making it difficult to see beyond the next aisle. You might memorise the warehouse floor plan, but it doesn't show how it looks when it's fully stocked.

Plan emergency lighting around actual aisle use, accounting for obstructions, intersections, and changes in direction. The key part of emergency lighting is understanding how people will move in an emergency.

Loading Bays and Goods-In Areas

Loading bays are busy areas. Vehicles, equipment, people, dock edges, and changes in floor level can become obstacles when the lights suddenly go out.  Properly positioned emergency lighting can help make these hazards more visible and support safe movement towards an exit.

When planning this area, pay attention to pedestrian walkways, access doors, steps, and level changes. Don’t plan only for internal emergency lighting, as people might need to cross a yard or move from an exit to safety.

Escape Routes, Stairways, and Final Exits

Escape routes typically include corridors, stairs, and exit doors. Prioritise these for emergency lighting to support a smooth journey to safety. The aim is to help people follow the route without stumbling or becoming disoriented.

People should be able to easily identify direction signage and final exits. This is where emergency exit signs come in. But let’s be clear: they’re different from emergency lighting. Signs help people recognise where to go, while lighting helps them see the route. One doesn't replace the other.

Picking Stations, Packing Areas, and Ancillary Rooms

Understand that some spaces may need emergency lighting because they're part of an escape route. Others may require it because of the hazards present or the activities taking place. Picking and packing stations may contain conveyors, benches, wrapping equipment, and other obstacles. These areas also need emergency lighting.

Other locations to consider are offices, welfare facilities, plant rooms, and dispatch areas.

Which Types of Emergency Lights Suit Warehouses?

There’s no one-size-fits-all emergency lighting for warehouses. You have options, with each type serving a different purpose. The best choice depends on the space, mounting position, environmental conditions, and required lighting performance.

Emergency Bulkhead Lights

These compact, practical fittings are commonly used in corridors, access routes, service areas, and certain external approaches. Their enclosed design can make them a useful option in busy environments such as warehouses.

But not every bulkhead is designed for the same conditions. Check the IP rating for protection against dust and moisture, as well as any impact-resistance rating. Depending on where you install the lights, they may be exposed to knocks and impacts. Also check the mounting height and light distribution, as these can affect the light’s effectiveness during emergencies.

Emergency Twin Spot Lights

This is probably what you immediately imagined when you read “emergency lights”. This box-like device with two light heads is common in commercial, industrial, and open-plan buildings in the UK. You can direct the lights toward different parts of an area, which makes them well-suited for corners and intersections.

However, adjustable heads don't automatically guarantee good coverage. Their direction, mounting position, beam distribution, and the presence of racking or machinery all affect the result. In other words, you still need to plan and test installation locations for maximum effectiveness.

Emergency Downlights and Emergency-Backed LED Fittings

For a more discreet installation, some downlights and compatible LED fittings support emergency lighting.

Depending on the model you choose, they may have a built-in emergency function or require a compatible emergency conversion kit. If you use a conversion kit or a separate backup arrangement, first check whether your lights are compatible. An ordinary LED fitting doesn't automatically continue working during a power cut.

Other things to check before buying:

• How its emergency operation works

• Whether the required battery or backup components are included

• How long it can provide emergency illumination

Illuminated Emergency Exit Signs

These help occupants identify escape doors and follow directional changes along designated routes. They're useful in large warehouses where exits may not be immediately visible from every location.

There are two types of emergency signs:

• Maintained signs are designed to work during normal operation and remain illuminated during an emergency.

• Non-maintained signs only turn on when the normal power supply fails.

The choice depends on the site's requirements and lighting design. One last thing to understand: An illuminated sign indicates the way out, but you still need adequate emergency escape lighting for clear visibility.

Warehouse Emergency Lighting Requirements and Compliance

Emergency lighting is an important part of workplace fire safety, so a suitable risk assessment and lighting design should be in place.

Understanding BS 5266 and Fire Safety Responsibilities

We can’t talk about emergency lighting without mentioning the key British Standard that covers this: BS 5266. It provides a code of practice for designing and installing emergency lighting. The Regulatory Reform (Fire Safety) Order 2005 in England and Wales also places duties on the “responsible person” to assess fire risks and provide appropriate general fire precautions.

Ensuring emergency routes and exits that require illumination have adequate emergency lighting if normal lighting fails is just one example of these responsibilities. Different legislation applies in different parts of the UK, so warehouse operators should check the rules relevant to their location.

Emergency Lighting Coverage, Illumination, and Duration

So, do you just get the brightest emergency lights you can get and call it a day? Different areas may require different illumination levels. This means escape routes, large open spaces, and hazard areas aren't necessarily assessed the same 2way. The design then should have:

• Suitable illumination levels

• Proper fitting positions

• Backup duration

All of which should align with applicable standards and the premises' needs. Ceiling height, aisle width, obstructions, and light distribution also influence the outcome, so consider those.

For backup duration, standard UK regulations and codes of practice require a minimum of three hours. Though a minimum of one hour is technically permitted only in specific low-risk buildings where the premises can be evacuated immediately.

Maintained vs Non-Maintained Emergency Lighting

This is a choice you’ll have to make when dealing with emergency lights.

• Maintained emergency lighting: The fitting works like a regular light during normal operation and maintains the illumination when the normal supply fails.

• Non-maintained emergency lighting: The fitting normally remains off and turns on only when the normal lighting supply fails.

Which one should you choose then? The choice depends on the location, the fitting's function, and the overall emergency lighting design. In other words, one is not better than the other.
