Category 3 open fire

A category 3 open fire, as defined in the Wildfire Regulation, refers to any fire that burns:

  • Material concurrently in 3 or more piles, each not exceeding 2 metres in height and 3 metres in width
  • Material in one or more piles, each exceeding 2 metres in height or 3 metres in width
  • One or more windrows, not exceeding 200 metres in length or 15 metres in width
  • Stubble or grass over an area exceeding 0.2 hectares (2,000 square metres)

Legislative requirements

The person who lights, fuels or uses a category 3 open fire must adhere to the following requirements, as outlined in the Wildfire Regulation. Additionally, anyone planning a category 3 open fire is required by the Environmental Management Act to follow the Open Burning Smoke Control Regulation (OBSCR).

 

Before the burn

Prior to burning a category 3 open fire, the person responsible for the fire must:

  • Ensure the open fire is not lit during a category 3 open fire prohibition
  • Check with local authorities, such as a fire department, First Nation, municipality or regional district, to determine if your area has any additional restrictions or requires a permit from your local government to burn
  • Register the fire to obtain an Open Fire Tracking System (OFTS) burn registration number
  • Comply with any additional regulations and/or restrictions provided when you obtain your burn registration number
  • Always comply with the Environmental Management Act and Open Burning Smoke Control Regulation
  • Only light a fire if conditions are safe and will continue to be safe

A fuel break (sometimes called a firebreak) must be established and maintained around the category 3 open fire. Please review the Wildfire Regulation and Policy 9.12 for additional fuel break requirements during a category 3 open fire.

 

Smoke control regulation

Smoke is a health hazard regulated under the OBSCR. The open burning rules outlined in the OBSCR are intended to minimize smoke and risk to human and environmental health.

Before you burn, visit the Open Burning Smoke Control Regulation page for more information on:

 

During the burn

To prevent the fire from spreading beyond the fuel break, the person responsible for the fire must ensure:

  • A fire suppression system is available at the burn area, of type and capacity adequate for fire control if the fire spreads beyond the fuel break
  • At least one individual is patrolling the fire at all times and is equipped with at least one firefighting hand tool
  • The fire does not exceed the capacity of those patrolling the fire from spreading beyond the fuel break

If the category 3 open fire spreads beyond the fuel break or becomes out of control, the person responsible for the fire must:

  • Carry out fire control measures immediately and extinguish the fire if practicable
  • Report the escaped fire to the BC Wildfire Service as soon as possible. If the burn site falls within the jurisdiction of a local fire department, report the escaped fire by calling 9-1-1
 

Extinguishing the burn

When extinguishing a category 3 open fire, the person responsible for the burn must:

  • Confirm full extinguishment of the category 3 open fire by the date specified by the official or person who issued the OFTS burn registration number
  • Ensure the person who extinguishes the fire documents all actions taken to confirm the fire is completely extinguished
  • Be prepared to provide documentation of actions taken to confirm extinguishment of a category 3 open fire at the request of an official, per Section 22(2.1) of the Wildfire Regulation

Users of category 3 open fires are encouraged to use a documentation method that aligns with their specific needs and practices. Documentation may include the following information: 

  • Burn registration number 
  • Name of the burn registration number holder 
  • List and location of ignited piles 
  • Date(s) of ignition and date(s) of active burning 
  • Date by which the open fire was to be extinguished 
  • Description and dates of the actions taken to confirm extinguishment 
  • Description and dates of follow-up activities taken to confirm extinguishment 
  • Name(s) of the person(s) who carried out the actions 

To support the description of the actions taken to confirm extinguishment, consider also including the following: 

  • Photographs 
  • Maps 
  • Sketches or diagrams 
  • Weather data, weather forecasts, and the name of the representative weather station 
  • Observations about fire behaviour, fuel breaks, and other site conditions 
  • Type and quality of burned material 

Burn registration

Anyone planning on lighting a category 3 open fire or category 4 resource management open fire is required to register their burn with the BC Wildfire Service and obtain a burn registration number. Burn registration numbers are logged into the Open Fire Tracking System (OFTS), along with details about the registered burn.

The registration number is not a burn permit. The BC Wildfire Service does not issue permits for burns. However, local governments may require permits for burns within their jurisdiction. It is the responsibility of the person conducting the burn to check with local authorities about local bylaws and permit requirements.

Burn registration numbers are normally issued for a period of two weeks. If your category 3 open fire will not be extinguished within that time, your burn registration number may be renewed by calling 1-888-797-1717 or by emailing hpr.1800@gov.bc.ca

How to register a burn

To obtain a burn registration number, call 1-888-797-1717 or by email hpr.1800@gov.bc.ca

You will be asked to provide the following information:

  • Contact information for yourself and/or the company you are burning with. The contact person must always be available during the burn
  • Details of your burn, including the number and/or size of piles, windrows, grass or stubble areas being burned
  • Legal descriptors and coordinates or residential address of the burn location

If you send your request via email, please provide a phone number in case the BC Wildfire Service needs to contact you for further details.

Please note that simply emailing the BC Wildfire Service does not fulfill the requirement for obtaining a burn registration number. You must receive a response with a number and notice that your registration number is active. 

Legal descriptors

If burning on private property, you must provide two different legal descriptors for the property. These can be found on Property Assessments or Tax Papers. Please note, residential address cannot be used as a legal descriptor. 

If burning on Crown land, you must provide one legal descriptor of the land.

Open Fire Tracking System

The Open Fire Tracking System (OFTS) allows the BC Wildfire Service to track regulated burning across B.C., manage firefighting resources and minimize false reports of wildfires.

The Ministry of Environment and local fire departments are also entitled to read-only access of OFTS data. This allows for shared information and improved fire management.

OFTS Registered Burns and Prescribed Fire Map

All category 3 open fires and category 4 resource management open fires registered with OFTS are plotted on an interactive map that is publicly available. 

OFTS Interactive Map

This map includes active registrations, as well as those that have expired within the last 7 days.

Please note that the map represents active registrations, but not necessarily active fires. 

Safer burning best practices

Always follow the Wildfire Regulation legislative requirements when using category 3 open fire. To further reduce the risk of wildfire when conducting a category 3 open fire, follow the safer burning best practices outlines below.

 

Constructing fuel breaks

A fuel break may be a change of fuel type, an area with fuel removed or a natural barrier, such as snow, bodies of water or bare rock. A fuel break is only sufficient if it prevents fire spread and should be assessed throughout the burn for its ability to prevent fire spreading.

Consider how burn location and local current and forecast weather conditions will impact your fuel break, including:

  • Topography (slope, aspect, terrain)
  • Content and quality of burned material in pile
  • Adjacent fuels
  • Moisture levels
  • Fire behaviour
  • Wind and weather
 

Burning piles

Choosing your burn location and timing:

  • Whenever possible, burn piles when there is still snow cover and the ground is frozen 
  • Avoid building piles in areas with buried organic matter material, such as muskeg, rotten log decks or boggy areas, or deep organic soils like peat. These can create deep burning and underground smouldering, which can reignite in warm, dry and/or windy conditions
  • Never burn in windy conditions

Constructing piles:

  • Hot fires produce less smoke. Build piles to allow air flow and good combustion
  • Create a stable haystack-like structure that does not have long sloping sides
  • Piles should have fine fuels on the bottom with larger fuels on top or leaned on the outside of the pile to form a pyramid structure

Burning piles:

  • To minimize unburned material, pile tending is recommended. Push outside material into the centre of the burn pile until all debris is consumed
  • When you've finished burning your pile, check the burn site for hot spots. Hot spots may continue to smoulder and could flare again, weeks or months later

For more information on pile burning, read the Wildfire Risk Reduction Pile Construction and Burning Guidance document. This document will help ensure that category 3 pile construction and burning occurs in a manner that:

  • Reduces the risk to surrounding structures and communities
  • Minimizes smoke emissions
  • Avoids or limits damage to standing trees
  • Complies with legal requirements under the Wildfire Act and Environmental Management Act 
 

Burning windrows

A windrow is a pile of hay, grain, leaves or other organic material left to dry.

When building and burning windrows, remember to:

  • Avoid building windrows in muskeg areas, where fire can burn deep into the duff layer
  • Avoid pushing dirt into the windrows, as this will smother the fire, cause it to burn continuously and produce more smoke
  • Use a brush rake or excavator to build windrows whenever possible to help keep dirt out of the rows and encourage better burning
  • Build windrows perpendicular to the direction of the prevailing wind
  • Ensure that all windrows are built no closer than 25 metres from standing timber
  • Never burn in windy conditions
 

Burning grass and stubble

When burning grass and stubble areas:

  • Avoid burning in the heat of the day. Whenever possible, burn in the evening
  • Blade or plow a fire guard (a minimum of 5 metres wide) all around your burn site, right down to mineral soil
  • Burn larger fields by working on smaller sections individually, with fire guards built around each section
  • Never burn in windy conditions

Offences and fines

Anyone found in violation of an open fire prohibition may be fined up to $1,150. If your fire escapes and results in a wildfire, you may be fined up to $1 million, be sentenced for up to 1 year in jail as well as be responsible for all firefighting and associated costs.
