1. Fire prevention objectives
The fire prevention measures in this guidance have been designed to meet these 3 objectives:
- minimise the likelihood of a fire happening
- aim for a fire to be extinguished within 4 hours
- minimise the spread of fire within the site and to neighbouring sites
If you submit a plan which includes all of the measures in this guidance, the Environment Agency is likely to approve your plan.
However, you can discuss other fire prevention measures with the Environment Agency. You can propose:
- alternative fire prevention measures – if you can demonstrate they’ll still meet the 3 objectives
- that you don’t need to extinguish a fire within 4 hours at your site, for example because it isn’t close to sensitive receptors - but you must still meet the other 2 fire prevention objectives
You should contact the Environment Agency as soon as possible if you want to propose either of these options. The Environment Agency will discuss your proposals and the level of technical detail you need to provide.
If you don’t put in place and use your fire prevention measures, the Environment Agency may take enforcement action.
This guidance doesn’t replace statutory requirements or other applicable legislation.
It’s your responsibility to check which statutory requirements apply to you.
2. Who this guidance applies to
This guidance applies to operators that store any amount of combustible waste.
It applies to operators from these sectors:
- waste metals (end of life vehicle (ELV) sites and scrap metal)
- non-hazardous waste
It also applies to operators in any of these sectors but you may not have to include all of your activities in your fire prevention plan:
- biowaste treatment (open windrow, in-vessel composting and dry anaerobic digestion)
- agriculture (intensive farming only)
- paper and pulp
- cement lime and minerals
If you’re in one of these sectors, contact the Environment Agency for more information.
3. Who this guidance doesn’t apply to
This guidance doesn’t apply to:
- biowaste treatment (wet anaerobic digestion)
- biowaste use (land spreading)
This guidance also doesn’t apply to the storage of coal, materials, or wastes that are:
- hazardous wastes – excluding waste electrical and electronic equipment (WEEE), but including hazardous waste batteries accepted as a separate waste stream, covered by Sector Guidance Note 5.06
- dangerous substances stored under the Control of Major Accident Hazards Regulations
This guidance doesn’t apply to non-waste materials such as gas cylinders, aerosols and combustible liquids. They are covered by ‘Guidance for the storage and treatment of aerosol canisters and similar packaged wastes’. However, you must still consider these in your fire prevention plan because they can cause or increase the impact of fire on a site.
If you aren’t sure if this guidance applies to you, please contact the Environment Agency.
4. Types of combustible waste
Combustible waste includes:
- paper or cardboard
- rags and textiles
- scrap metals contaminated or mixed with other waste such as oils or plastics
- de-polluted and un-depolluted ELVs
- refuse derived fuel (RDF) and solid recovered fuel (SRF)
- compost and plant material
- mixed waste containing any combustible wastes
The following are also types of combustible waste.
This could be natural or synthetic and includes:
- whole tyres
- baled tyres
- tyre shred, crumb and fibre
- firewood or chips
- wood joined to form crates, pallets, casks or barrels
4.3 Fragmentiser waste
This includes waste from:
- processing ELVs
- plastics and metal wastes from materials recovery facilities
- computers and televisions containing combustible materials such as plastic (including any batteries within this equipment)
These lists provide examples of combustible waste and are not exhaustive. If you’re not sure what to do contact the Environment Agency for advice about:
- other materials and activities not listed in this guidance
- whether you need a fire prevention plan
5. Using your fire prevention plan
Your fire prevention plan forms part of your management system. It sets out the fire prevention measures and procedures you must put in place and use on your site.
Your fire prevention plan must be a standalone document within your management system so that you and your staff can easily refer to it.
You must make sure that staff know where you keep your fire prevention plan. They must be able to access it easily at all times, including during an incident.
All staff and contractors working on site must understand the contents of the fire prevention plan so that they know what they must do:
- to prevent a fire occurring
- during a fire if one breaks out
You must have regular exercises to test how well your plan works and make sure that staff understand what to do. Set out in your plan how often you’ll carry out these exercises.
6. Fire prevention plan contents
Your fire prevention plan must set out all the measures you’ll put in place to reduce the risk of a fire breaking out.
You must identify all the possible causes of a fire at your site. You must then set out the measures you will put in place to address those fire risks. These measures will depend on the activities you’re carrying out. The Environment Agency expects your plan to include the measures covered in this guidance.
Your fire prevention plan must also cover the following information.
6.1 Activities at your site
Your fire prevention plan must provide details of the different types of activities you carry out at the site. This includes your waste management activities but also any other activities that could be a fire risk.
6.2 Site plans and maps
Your fire prevention plan must include a site plan(s) drawn to scale, showing:
- layout of buildings
- any areas where hazardous materials are stored on site (location of gas cylinders, process areas, chemicals, piles of combustible wastes, oil and fuel tanks)
- main access routes for fire engines and any alternative access
- access points around the site perimeter to assist fire fighting
- hydrants and water supplies
- areas of natural and unmade ground
- the location of fixed plant or where mobile plant is stored when not in use
- drainage runs, pollution control features such as drain closure valves and fire water containment systems
- storage areas with pile dimensions and fire walls (where applicable) - includes wastes stored in a building, bunker, or containers
- the quarantine area
You must have plans showing all sensitive receptors within a 1km radius of your site that could be affected by a fire. Examples of sensitive receptors may include:
- schools, hospitals, nursing and care homes, residential areas, workplaces
- protected habitats, watercourses, groundwater, boreholes, wells and springs supplying water for human consumption
- roads, railways, bus stations, pylons (on or immediately adjacent to the site only), utilities, airports
Plans should have a compass rose showing north and the prevailing wind direction.
7. Manage common causes of fire
You should understand common causes of fire and the measures you can take to reduce the risk. Some of these risks may not apply to your site or there may be others you need to include in your fire prevention plan. It’s your responsibility to identify all possible risks, depending on the activities you carry out on your site.
You must have security measures in place, such as security fencing, intruder alarms and CCTV. These must include arrangements for outside of working hours.
7.2 Plant and equipment
- have a maintenance and inspection programme for static and mobile plant and equipment
- fit vehicles with fire extinguishers
- keep mobile plant that isn’t being used away from combustible waste
7.3 Electrical faults including damaged or exposed electrical cables
Electrics on site must be fully certified by a qualified electrician and you must have written procedures in place that set out the regular maintenance.
7.4 Discarded smoking materials
You must apply a no smoking policy or have designated smoking areas a safe distance from combustible wastes to prevent accidental ignition.
7.5 Hot works
You must ensure staff and contractors follow safe working practices, such as a permit to work system, when carrying out hot works such as welding and cutting. You should carry out a fire watch for a suitable period after hot works have ended, particularly at the end of a working day.
7.6 Industrial heaters
You must have written procedures that set out the use and regular maintenance of industrial heaters.
7.7 Hot exhausts
You must carry out a fire watch at regular intervals during the working day to detect signs of a fire caused by dust settling on hot exhausts and engine parts. Set out in your plan how regular these intervals are. You must also do this at the end of the day. A fire watch can simply be carrying out visual checks.
7.8 Ignition sources
You must keep naked flames, space heaters, furnaces, incinerators and other sources of ignition 6 metres away from combustible and flammable waste.
7.9 Batteries in ELVs
Batteries left connected in un-depolluted vehicles can short circuit and cause fires. You must disconnect or remove batteries from un-depolluted vehicles before they’re stockpiled for de-pollution.
7.10 Leaks and spillages of oils and fuels
You must prevent fuels and combustible liquids leaking or trailing from site vehicles and ELVs. For example, this includes from vehicles:
- being tracked around the site
- before or after the de-pollution process
7.11 Build-up of loose combustible waste, dust and fluff
Your plan must state how regularly you’ll inspect and clean the site to prevent the build-up of loose combustible waste, dust and fluff.
7.12 Reactions between wastes
You must have written procedures for waste acceptance checks to prevent reactions between incompatible or unstable wastes, including lithium batteries. You must use a quarantine area where necessary.
7.13 Deposited hot loads
You must have a quarantine area for hot loads.
8. Prevent self-combustion
Many wastes can self-combust under certain conditions. Self-combustion happens when a material which can self-heat generates heat at a faster rate than it can be lost to the environment. The temperature continues to rise in the material speeding up the rate of reaction and releasing even more heat. Eventually the material reaches auto-ignition and the material then self-combusts.
You can prevent self-combustion by carefully managing storage times, pile volumes and height, and the temperature of the wastes.
8.1 Manage storage time
To help prevent self-combustion your plan must define the maximum storage time of all materials on site and how you’ll control and monitor this.
You must use good stock rotation for all stored materials. Your fire prevention plan must show that you have a clear method to record and manage the storage of all waste on site.
You must make sure that any combustible wastes are stored for less than 6 months (unless the material is compost and the Environment Agency has agreed that you can store it for longer).
Storing combustible wastes for longer than 6 months could increase the likelihood of a fire. If you propose doing this, the Environment Agency is unlikely to approve your fire prevention plan.
If you’re storing combustible wastes in the maximum pile sizes for longer than 3 months, you must show what extra measures you’ll use to prevent self-combustion. For example, this could include monitoring temperatures in the waste.
At these maximum dimensions, the possibility of self-combustion can increase when combustible wastes are stored for more than 3 months.
If there are seasonal variations in demand or supply for the combustible waste, you must demonstrate how you’ll manage these variations. You must show how you will follow the ‘first in, first out’ principle so that wastes are stored for no longer than 6 months.
8.2 Monitor and control temperature
Your plan must show that you’ll control heat to prevent self-combustion. You must:
- reduce the exposed metal content or proportion of ‘fines’ within the waste (exposed metals can oxidise which will generate heat, while fine particles are more prone to self-combustion)
- allow any heat generated during treatment such as shredding, chipping or producing crumb to be released so that the waste is cool before you form it into piles for storage
- monitor sub-surface temperature with a probe or other device that can take representative readings from the centre of a pile - temperature on the surface is unlikely to represent that at the core
- explain in your plan the triggers you will use in relation to temperature, and actions you will take in response – including ensuring staff are trained to detect and manage hotspots
- routinely turn piles to ensure the waste remains cold and any localised warming is dissipated quickly
- take into account external heating during hot weather and consider shading waste from direct sunlight or using other techniques to enable heat generated within the pile to be released
8.3 Waste bale storage
If you’re storing waste in bales your plan must show:
- what sampling and testing protocol you will use to make sure you assess a representative number of bales (minimum 10%) during monitoring
- that you get representative temperature readings from the centre of the bales and from bales within the centre of a pile
- that you turn the bales to make sure the waste stays cold
9. Manage waste piles
If you manage waste piles carefully, you will:
- help prevent the risk of self-combustion
- limit the scale of a fire if one breaks out
- minimise pile sizes (small piles with appropriate separation are safer than one big one)
- store waste materials in their largest form
Here are measures you must use to manage piles of waste effectively.
9.1 Maximum pile sizes
|Waste type||Loose and more than 150mm||30 to 150mm or baled||Less than 30mm|
|Tyres and rubber||450 cubic metres||300 cubic metres||300 cubic metres|
|Wood||750 cubic metres||450 cubic metres||300 cubic metres|
|Compost and green waste (excluding during the active composting process)||750 cubic metres||450 cubic metres||450 cubic metres|
|RDF and SRF||450 cubic metres||450 cubic metres||450 cubic metres|
|Plastics||750 cubic metres||450 cubic metres||300 cubic metres|
|Paper and cardboard||750 cubic metres||750 cubic metres||450 cubic metres|
|Textiles||750 cubic metres||750 cubic metres||400 cubic metres|
|WEEE containing plastics, including fridges, computers and televisions||450 cubic metres||450 cubic metres||450 cubic metres|
|Metals other than WEEE (including crushed ELVs, which are classed as ‘baled’ waste for the purpose of this table. For whole ELVs see below)||750 cubic metres||450 cubic metres||450 cubic metres|
|Fragmentiser fluff||450 cubic metres||450 cubic metres||450 cubic metres|
For all waste piles, the maximum height allowed is 4 metres.
When measuring height, you must use the longest measurement between the base of the pile and the top. This is to allow for any uneven ground beneath the waste.
For all waste piles, the maximum length or width allowed (whichever is the longest) is 20 metres.
If your waste piles contain a mixture of combustible wastes, you should work out the maximum limits based on the type of waste that makes up most of a mixed pile.
You need to consider the design, access and layout of a building when storing waste so a fire can be extinguished easily.
10. Where maximum pile sizes don’t apply
Maximum pile sizes don’t apply for these types of waste.
10.1 Whole end of life vehicles (ELVs)
You must set out in your fire prevention plan how you will store ELVs. Each vehicle must be accessible from at least one side:
- to allow a fire to be fought
- so unburnt vehicles can be accessed and moved to prevent the fire spreading
These rules will limit any row to a depth of 2 vehicles.
Where you store vehicles one on top of another, or on racking, you must limit this to 3 vehicles high so the stack can remain stable during a fire. You must maintain a separation distance of 6 metres between rows or blocks of vehicles.
10.2 Waste stored in containers
If you store waste in containers that can hold more than 1,100 litres, each one must be accessible so any fire inside it can be put out. Examples of these types of containers include skips, roll-on roll-off skips, or shipping containers.
If you have a fire, you must be able to move containers as soon as is reasonably practicable to prevent the fire spreading. You must set out in your fire prevention plan the procedures you will put in place to allow this to happen.
For all other containers holding waste, the maximum pile sizes apply.
10.3 Compost production
For composting activities, the maximum pile sizes don’t apply when the waste is actively managed and monitored during the composting process. Waste stored before and after active composting must follow the maximum pile sizes.
11. Prevent fire spreading
There are 2 main ways to prevent a fire from spreading.
11.1 Separation distances
- store your combustible waste piles with a separation distance of at least 6 metres
- have a separation distance of at least 6 metres between waste piles and the site perimeter, any buildings, or other combustible or flammable materials
These rules don’t apply if you’re composting the waste through an actively managed process.
11.2 Fire walls and bays
You can reduce separation distances by using fire walls and bays. Fire walls and bays must be designed to:
- resist fire (both radiative heat and flaming)
- have a fire resistance period of at least 120 minutes to allow waste to be isolated and to enable a fire to be extinguished within 4 hours
If you store waste in a bay, your fire prevention plan must show how:
- you’ll carry out full and frequent stock rotation, ensuring you have a first in, first out policy, and how this will be monitored and recorded
- you’ll check the temperatures of all the waste within the bay so that you carry out representative checks on the entire volume of the pile
- the specification and construction of the walls offer a thermal barrier and how any joints will be adequately sealed
- you have taken into account the calculation of flame height and radiation in preventing the spread of fire between piles
- you’ll prevent brands or lighted material moving outside the bay walls and igniting other wastes
- you’ll keep a ‘freeboard’ space at the top and sides of the walls clear at all times to prevent fire spreading over the walls
- you’ll use the quarantine area
- quickly and effectively you’ll remove wastes from bays and isolate it during an incident
12. Quarantine area
A quarantine area is somewhere you can place burning wastes to extinguish them. You can also move unburnt wastes into the quarantine area to isolate and prevent them catching fire.
The quarantine area must be within the boundary of the site for which you hold a permit.
You must have a quarantine area which is large enough to both:
- hold at least 50% of the volume of the largest pile, row or block of ELVs or containers on your site
- have a separation distance of at least 6 metres around the quarantined waste
You must set out in your fire prevention plan the location of this area and the volume of waste that it can hold.
For operational reasons you may want to keep the location of the quarantine area flexible. If so, you must identify on your site plan all the areas you could use.
You must keep at least one specified quarantine area clear at all times – unless it’s being used in the event of a fire.
If you use your quarantine area to store material temporarily (for example, non-permitted wastes) you must make sure you remove those wastes as soon as is practicable. In the event of a fire, you must remove it immediately. Your fire prevention plan must include details of the procedure you will use to do this.
You must set out how you will use your quarantine area in the event of a fire. You must be able to move waste to it as soon as possible or, at most, within 1 hour of a fire starting.
13. Detecting fires
You must have procedures in place to detect a fire in its early stages so you can reduce its impact.
Your detection system should be proportionate to the nature and scale of waste management activities you carry out and the associated risks.
Appropriate automated systems may include:
- smoke and heat detectors including temperature probes
- CCTV visual flame detection systems
- spark, infrared and ultraviolet detection
The design, installation and maintenance must be covered by an appropriate UKAS-accredited third party certification scheme.
14. Suppressing fires
If you store waste in a building, you must install a fire suppression system. This system should be proportionate to the nature and scale of waste management activities you carry out and the associated risks.
Your system needs to enable a fire to be extinguished within 4 hours. When deciding what type of system to install you need to take into account that:
- the fire and rescue service may not be able to enter the building during a fire
- a suppression system may not extinguish a fire, although it may prevent a fire spreading and then allow the fire to be fought effectively by the fire and rescue service
Appropriate fire suppression systems may include:
- water spray (deluge) systems
- water curtains
- fire blankets
You must make sure the design, installation and maintenance of all your automated suppression equipment is covered by an appropriate UKAS-accredited third party certification scheme.
15. Firefighting techniques
You must design your site to allow for active firefighting. This will help allow a fire to be extinguished within 4 hours.
Active firefighting doesn’t mean that you or your staff have to fight the fire. No one should put themselves at risk by trying to fight a fire.
Active firefighting means having the resources available at all times to fight a fire – including in the event of a fire. The resources needed include:
- plant you can use to move waste around the site, for example loaders, excavators, material handlers
- available water supply
A variety of firefighting techniques are used together or separately to extinguish a fire. These include:
- applying water to cool unburned material and other hazards
- separating unburned material from the fire using heavy plant
- separating burning material from the fire to quench it with hoses or in pools or tanks of water
Firefighting techniques may also include suffocating the fire using soil, sand, crushed brick or gravel. However, you can only do this if:
- the Environment Agency has agreed you can do this
- you remove and dispose of contaminated material as soon as it’s safe to do so
All these techniques may be used by staff on site if they’re suitably trained and are supervised by the fire and rescue service. However, protecting the health and safety of people on site must be your priority.
16. Water supplies
You must have enough water available for firefighting to take place and to manage a worst case scenario. Depending on your site this could be water in storage tanks or lagoons on site, or access to hydrants or mains water supply.
A worst case scenario would be your largest waste pile catching fire.
You’ll need a water supply of at least 2,000 litres a minute for a minimum of 3 hours for a 300 cubic metre pile of combustible material.
You may be able to reduce water volumes needed if you have a system that lets the fire and rescue service re-circulate the water they are using to fight the fire (fire water). However, you may need to filter this water and the fire and rescue service will also need to connect to your system. It may not always be appropriate or safe to re-circulate the water.
17. Managing fire water
You must be able to contain the run-off from fire water to prevent pollution of the environment.
The containment facilities and pollution equipment you need will depend on the:
- size of your site
- amount of waste you store
- firefighting strategy
Read ‘Containment systems for the prevention of pollution (C736)’ to help you find out what facilities and equipment you need for your site.
You must take all the steps that are reasonably practicable to minimise pollution from fire water. For example, preventing fire water entering:
- surface waters, for example rivers, streams, estuaries, lakes, canals or coastal waters
- into the ground
If you don’t you may be committing an offence and the Environment Agency may take enforcement action.
Secondary and tertiary containment facilities for fire water run-off include:
- impermeable bunds
- storage lagoons
- shut-off valves
- isolation tanks
- modified areas of your site such as a car park
- pollution control equipment such as fire water booms and drain mats to block drains or divert fire water
You may also be able to divert fire water to your local sewers. You need agreement from the sewerage company before doing so.
Your environmental permit may let you store combustible wastes on hard standing rather than an impermeable surface with sealed drainage. If so, you must assess the potential effect of fire water on:
- the local groundwater and surface water bodies
- any well, spring or borehole within 50 metres used for the supply of water for human consumption, including private water supplies
Your fire prevention plan must set out how you’ll prevent fire water affecting these receptors, if applicable.
18. During and after an incident
Your plan must have contingency measures in place for dealing with issues during and after a fire. For example, these could include:
- diverting incoming wastes to alternative sites during a fire
- having a plan for how you will notify those who may be affected by a fire, such as nearby residents and businesses
You also need to set out in your fire prevention plan:
- how you will clear and decontaminate the site
- the steps you must take before the site can become operational again
19. Submit your fire prevention plan
If you’re applying for a permit to carry out a waste operation involving combustible wastes, you must send your fire prevention plan to the Environment Agency with your application.
For other types of permits, contact the Environment Agency to find out if you need to send them your fire prevention plan.
