Beyond Financial Liability: Preventing Lithium-Ion Battery Fires in Canadian Waste Management Facilities

On September 21, 2026, Resource Recycling published a pivotal industry report documenting a coordinated response from three of North America's most influential waste management trade organizations. The Solid Waste Association of North America (SWANA), the National Waste & Recycling Association (NWRA), and the Recycled Materials Association (ReMA) have jointly issued formal guidance addressing an issue that has become impossible for facility operators to ignore: the financial liability and operational safety risks created by lithium-ion batteries entering the waste and recycling stream.

For Canadian material recovery facilities (MRFs), recycling plant operators, and environmental health and safety (EHS) directors, this guidance arrives at a critical moment. Lithium-ion battery fires in recycling and waste handling environments are no longer rare anomalies — they represent an escalating operational threat that carries real consequences: equipment destruction, extended facility shutdowns, regulatory scrutiny, worker injury, and mounting insurance exposure.

This article unpacks what the joint guidance means, why lithium-ion battery fires present unique physical challenges, which Canadian operations face the greatest exposure, and what practical prevention and response measures facility managers should have in place today.

What Happened: Joint Industry Guidance on Lithium-Ion Battery Fire Liability

The September 21, 2026 report from Resource Recycling marks a significant shift in how the waste management sector is framing the lithium battery fire problem — moving it squarely into the domain of institutional accountability.

SWANA, NWRA, and ReMA — organizations that collectively represent thousands of waste management professionals across North America — have united to issue coordinated guidance acknowledging the following:

  • Lithium-ion batteries are entering the municipal solid waste and recyclables stream in rapidly growing volumes, driven by the proliferation of consumer electronics, e-bikes, e-scooters, power tools, and electric vehicle components.
  • When these batteries are mishandled, damaged, or improperly sorted, the resulting fire events cause disproportionate damage to MRF infrastructure relative to conventional fires.
  • The financial liability exposure for facility operators — from property damage to business interruption to third-party claims — has reached a level that the industry can no longer address informally.

The joint guidance calls on facility operators to formalize operational procedures, invest in appropriate protective equipment, implement staff training programs, and align with applicable local requirements. Critically, it frames these steps not only as safety obligations but as operational and liability risk-management imperatives.

For Canadian facilities operating under a patchwork of provincial workplace safety legislation, municipal waste management contracts, and insurance requirements, this guidance is directly relevant — even if it originated from U.S.-based trade associations.

Why Lithium-Ion Battery Fires Are Different

Understanding why lithium-ion battery fires demand a distinct response begins with the chemistry. Unlike conventional fires fuelled by paper, wood, or hydrocarbon materials, lithium-ion battery fires involve a process called thermal runaway — a self-reinforcing chain reaction within the battery cell itself.

Thermal Runaway and Self-Sustained Combustion

When a lithium-ion battery cell is mechanically damaged (crushed, punctured, or shredded), exposed to extreme heat, or suffers an internal short circuit, it can enter thermal runaway. This process generates intense internal heat that accelerates further chemical breakdown within the cell, producing flammable and toxic gases including hydrogen fluoride. The fire is, in effect, fuelled from within the battery rather than from an external ignition source.

This means that once thermal runaway begins, removing external oxygen — the conventional approach to fire suppression — has limited effect on the battery cell itself. The internal chemical reaction continues to generate heat regardless of what surrounds it.

Reignition Risk

One of the most operationally challenging aspects of lithium battery fire safety is the risk of reignition. A battery that appears extinguished can re-ignite hours after initial suppression, particularly if residual heat remains within the cell structure. This has significant implications for how waste management facilities approach post-incident monitoring and equipment handling.

Not All Battery Fires Behave Identically

The severity, behaviour, and suppression requirements of a lithium-ion battery fire depend on a range of factors: battery chemistry (lithium iron phosphate, NMC, and LCO cells each behave differently), the state of charge at the time of damage, the physical condition of the battery, and the surrounding environment. Facilities should not assume a one-size-fits-all response. Risk assessments should reflect the specific types of batteries most prevalent in their incoming material stream.

Who Is Most At Risk in Canadian Operations

The joint guidance from SWANA, NWRA, and ReMA is especially pertinent to the following Canadian facility types and roles:

Material Recovery Facility (MRF) Managers and Operators

MRFs receive commingled recyclables from residential and commercial sources. Consumer lithium-ion batteries — embedded in laptops, phones, tablets, power banks, and increasingly in e-mobility devices — routinely enter this stream despite disposal restrictions. Sorting equipment, baling lines, and compactors can crush or puncture these batteries, triggering thermal runaway events in the middle of active operations.

Waste Transfer Station and Landfill Operators

Waste handlers at transfer stations face a similar risk from garbage trucks compacting material that contains lithium-ion batteries. Even landfill operators are not immune — buried battery fires are notoriously difficult to detect and suppress.

Municipal Recycling Coordinators

Municipal coordinators who manage curbside collection contracts, household hazardous waste programs, and public drop-off depots are upstream actors in the lithium battery supply chain. Their decisions about consumer education, collection infrastructure, and sorting protocols directly affect the volume and condition of batteries reaching downstream facilities.

Environmental Health and Safety (EHS) Directors

EHS directors in waste management organizations face a dual challenge: protecting workers from an evolving and poorly understood hazard, while building a defensible record of due diligence that can withstand regulatory scrutiny and insurance review following an incident.

The financial exposure for all of these roles is real. Battery-related fires at recycling facilities have resulted in total losses exceeding millions of dollars per incident in North America. Canadian facilities are not insulated from this trend.

Prevention and Preparedness: Practical Recommendations

The joint industry guidance emphasizes that lithium-ion battery fire prevention is achievable through structured operational discipline. The following recommendations reflect the guidance's core themes, adapted for Canadian facility contexts.

Implement Rigorous Incoming Material Audits

Establish visual inspection checkpoints for incoming loads at the tipping floor level, before material enters sorting and processing equipment. Train sorters to identify and flag common battery-containing products — laptops, power banks, e-bike batteries, cordless tools — for manual removal prior to processing.

Proper Charging Practices for On-Site Equipment

Facilities that use electric forklifts, tuggers, or other battery-powered equipment face an additional internal source of lithium battery fire risk. Use only manufacturer-approved charging equipment, avoid overcharging by using automated charging management where possible, and ensure that charging does not occur in proximity to combustible materials or in poorly ventilated spaces.

Establish Safe Storage Protocols

Battery storage areas — whether for collected lithium batteries awaiting hazardous waste pickup or for on-site equipment batteries — should be physically separated from high-combustible-load areas. Maintain clear signage, appropriate containment where warranted by risk assessment, and keep combustible materials away from charging and storage zones. Lithium battery storage safety practices should be formalized in writing and reviewed regularly.

Develop Formal Workplace Procedures and Emergency Plans

The guidance is explicit: informal, ad hoc responses are not sufficient for an incident that can escalate rapidly. Facilities should develop written standard operating procedures (SOPs) covering:

  • How to identify and handle a suspected damaged or thermally compromised battery
  • Evacuation routes and muster points specific to battery fire scenarios
  • Communication protocols for notifying emergency services
  • Post-incident documentation and reporting requirements

Emergency planning should be conducted in alignment with provincial occupational health and safety legislation — including requirements under Ontario's Occupational Health and Safety Act, British Columbia's WorkSafeBC regulations, and Alberta's Occupational Health and Safety Act, depending on your jurisdiction.

Invest in Employee Training

Thermal runaway, reignition risk, and the limitations of conventional fire suppression are not intuitive concepts for most workers. Structured training — delivered at onboarding and refreshed annually — should cover hazard recognition, response protocols, and the correct use of any specialized suppression equipment present at the facility.

Align with Applicable Local Requirements and Manufacturer Instructions

Canadian facilities operate under federal, provincial, and municipal frameworks that may impose specific obligations for hazardous waste handling, workplace safety, and fire prevention. Manufacturer instructions for battery-containing equipment should be treated as baseline safety requirements, not optional guidance.

Fire-Response Considerations and Equipment

Prevention is the priority. But facilities also need a credible, pre-planned response capability for the scenario where a battery fire event does occur. Having the right equipment on hand — and having staff trained to use it — is a component of due diligence that the joint guidance implicitly supports.

Why Conventional Extinguishers May Be Insufficient

Standard dry chemical or CO₂ fire extinguishers are designed to suppress conventional fires by interrupting combustion chemistry or displacing oxygen. They are generally not effective at cooling a battery cell undergoing thermal runaway. The fire may appear suppressed at the surface while the internal cell reaction continues, creating reignition risk.

AVD-Based Suppression Technology

Aqueous Vermiculite Dispersion (AVD) technology has emerged as a specialized suppression approach for lithium-ion battery fires. AVD agents work through a combination of cooling and coating mechanisms that address the surface fire while helping to reduce heat transfer to adjacent cells — a key concern when a fire involves a battery pack with multiple cells in proximity.

Facilities evaluating lithium battery fire extinguisher options should consider AVD-formulated extinguishers as part of their equipment assessment. Our 6L AVD Lithium Ion Battery Fire Extinguisher is a popular choice for facility floor use, while the AVD 50L Wheeled Lithium Ion Battery Fire Extinguisher is suited for larger-scale or high-risk areas. For compact applications, the AVD 2L Fire Extinguisher offers a portable option. Facilities may also consider the AVD Fire Suppression Kit as a comprehensive starting point for building out a response capability.

Fire Blankets for Containment

For smaller battery events — such as a single device undergoing thermal runaway on a sorting line — a lithium battery fire blanket can provide a containment mechanism that limits fire spread and reduces radiant heat exposure to workers and adjacent equipment. As with all response equipment, blankets must be appropriate for the size and type of battery involved, and staff must be trained in their correct deployment.

Broader Facility Fire Protection

Facilities managing significant volumes of battery-containing materials should evaluate their broader lithium battery fire protection infrastructure: sprinkler system adequacy, detection and alarm coverage in sorting areas, fire separation between processing and storage zones, and access for emergency responders. EV battery fire safety considerations are increasingly relevant as electric vehicle components enter the waste stream through end-of-life vehicle processing. For facilities with enclosed areas where battery-powered vehicles are charged or parked, warehouse battery fire risk assessments should inform both equipment selection and spatial planning.

Product selection must be driven by a site-specific risk assessment. LithiumSafe Fire recommends working with qualified safety professionals to match equipment specifications to your facility's actual hazard profile.

Frequently Asked Questions

Are Canadian MRFs legally required to have specific lithium battery fire safety equipment?

There is no single national standard that mandates specific lithium battery fire equipment for Canadian MRFs. However, provincial occupational health and safety legislation generally requires employers to identify workplace hazards and implement appropriate controls. If lithium-ion batteries are present in your facility's material stream or on-site equipment, they constitute a recognized hazard, and the absence of appropriate controls could expose your organization to regulatory and liability consequences.

Can standard water or CO₂ extinguishers be used on a lithium battery fire?

Conventional extinguishers can suppress the surface flame of a battery fire but are generally not effective at cooling the battery cell undergoing thermal runaway. This creates a reignition risk. AVD-formulated extinguishers and fire blankets are specifically designed for lithium battery fire scenarios and are more appropriate as primary response equipment.

What is thermal runaway, and how quickly can it escalate?

Thermal runaway is a self-reinforcing, heat-generating chemical reaction within a lithium-ion battery cell. Once initiated — by mechanical damage, overheating, or internal failure — it can escalate rapidly, spreading to adjacent cells within a battery pack. The speed of escalation depends on battery chemistry, state of charge, and the number of cells involved. Early detection and a pre-planned response are critical.

How should a facility handle a battery that shows signs of thermal stress — swelling, heat, or off-gassing — but has not yet ignited?

A battery showing signs of thermal stress should be treated as an active hazard. Staff should not attempt to move or handle it without appropriate training and protective equipment. The immediate priority is to isolate the area, ensure personnel safety, and contact emergency services if the situation is uncertain. Written SOPs for this scenario should be developed in advance and reviewed with staff regularly.

Does the SWANA/NWRA/ReMA joint guidance apply to Canadian facilities?

The guidance was issued by North American trade organizations and is not a Canadian regulatory instrument. However, its operational recommendations are consistent with general due diligence obligations under Canadian occupational health and safety frameworks and are directly applicable to Canadian facility operations.

How often should lithium battery fire safety training be provided to staff?

At minimum, training should be provided at onboarding for new staff and refreshed annually. Additional training should be triggered following any near-miss or incident involving battery materials, after significant changes in the facility's incoming material profile, or when new response equipment is introduced.

What types of facilities are most likely to encounter lithium-ion battery fires?

MRFs, waste transfer stations, e-waste processors, and municipal household hazardous waste depots face the highest exposure from batteries in the incoming material stream. Facilities that also charge electric forklifts, floor scrubbers, or other battery-powered equipment face an additional internal risk vector. Any facility combining both risks should treat lithium battery fire safety Canada as a priority operational concern.

Is a lithium battery fire blanket sufficient on its own for facility safety?

A fire blanket is a containment tool — effective for small, discrete battery events such as a single device. It is not a substitute for a comprehensive lithium battery fire protection strategy that includes appropriate extinguishers, storage controls, detection and alarm systems, staff training, and emergency planning. Equipment decisions should follow a site-specific risk assessment.
