When lithium‑ion batteries go into thermal runaway, they can burst or explode; releasing toxic gases, intense smoke, and high‑speed particles. In those critical minutes, the Lithium Fire Intervention Mask (LFIM) is engineered to give trained responders the chance to breathe safely and evacuate effectively.
Understanding the Lithium Battery Hazard
Lithium‑ion batteries are ubiquitous; in electric vehicles, energy storage units, e‑bikes, and countless electronic devices. Yet they carry an invisible risk: under stress, impact, or electrical failure, they may combust violently. Toxic gases such as hydrogen fluoride (HF), lithium hydroxide (LiOH), sulphur dioxide (SO₂), ammonia (NH₃), and others are released; along with carbon monoxide, hydrocarbons, soot, and shards at high velocity These hazards can seriously impair breathing, vision, and safe evacuation.
The Mask for Smoke and Toxic Fumes
Unlike standard smoke hoods or basic filtration masks, the LFIM firefighter gas mask is specially certified for lithium‑battery emergencies. It protects from:
- Toxic and noxious smoke and gases.
- High‑speed particles and fragments from explosions.
- Chemical irritants released during lithium‑ion fires
Certified under EN136:1998 (full-face), EN14387/A1:2008 (gas & particulate filters), EN168 (high-speed particle impact), and EN166 (eye/face protection), it meets strict European safety standards
Key Features & Benefits
15 Minutes of Critical Protection
The LFIM is designed to provide up to 15 minutes of protection against toxic gases and debris; long enough to evacuate or intervene in a Li‑ion fire safely
Compact, Deployable & Ready to Use
Vacuum‑sealed and foam‑packed, LFIM masks are ready for action. They require no annual maintenance and can be stored for up to five years if unopened and kept at –10 °C to 70 °C, away from UV light
Specialist Filter Protection
Dual bayonet‑fitted filters protect against a wide range of hazards: CO₂, CO, HF, HCl, LiOH, hydrocarbons, ammonia, SO₂, soot particles and high‑speed shards
Face and Eye Shielding
A durable polycarbonate visor protects the face and eyes from flames, soot, and high-speed fragments. The facemask is ergonomically designed for trained users
Unique European Product
LFIM is the only European product specifically developed for lithium‑ion battery incident protection, manufactured by Medisafe BV and complying with CE regulation EU 2016/425 and harmonized PPE standards
Who Should Use the LFIM?
The LFIM is designed for:
- Trained firefighters and first responders fighting Li‑ion battery fires.
- Company first‑aiders, fire wardens, security teams, and staff in EV charging, recycling, battery storage, and industrial installations
- Staff in parking garages, data centers, logistics hubs, workshops, transport facilities (trucks, trains, buses), and high‑rise commercial/residential buildings.
By equipping such personnel with LFIM along with F‑500 Li‑ion fire extinguishing systems, organizations can significantly raise the safety standard during lithium‑battery emergencies
Safe Usage: Guidelines & Instructions
Before use:
- Only use LFIM in open, well‑ventilated areas with 19–22% oxygen. Do not use in confined spaces or after expiry.
- Confirm the integrity of the mask, filters, straps, valves, and visor before deployment.
- Only use after proper training in firefighting and mask usage
Putting on the Mask:
- Tear open vacuum seal.
- Hang the mask around the neck.
- Position over the chin and forehead, then pull straps onto the head.
- Tighten straps in sequence for a snug, symmetrical fit (beneath ears, over, then crown of the head)
During use:
- Breathe calmly; expect some back‑pressure due to filtered intake.
- Maximum continuous use: 15 minutes.
Removing the Mask:
- Move to a safe zone; release buckle straps and pull off over the head.
- Immediately wash the body and change clothes to avoid chemical contamination.
- Dispose of the used mask properly or return it to the LFIM service center for overhaul and repackaging, if within validity
Storage & Maintenance
- Store in a dry, dark place, protected from UV and sunlight.
- Maintain storage temperature between –10 °C and 70 °C.
- No annual inspection required if unopened but return masks close to or past expiry for servicing and filter replacement. The refurbished unit can be service-dated for a fresh shelf life of up to 5 years
Why LFIM is a Game-Changer
- Tailor-Made for Lithium Fire Events
Ordinary smoke masks can’t filter out Li‑ion-specific toxins. LFIM is purpose-built for these unique hazards - Regulated Protection
Adheres to multiple European norms ensuring face, filter, and high-velocity particle shielding. - Rapid Deployment
Vacuum-packaging means it’s always ready; no upkeep, immediate accessibility. - Designed for Trained Use
Its effectiveness relies on prior training; making it part of a complete Li‑ion fire safety plan.
Reinforcing Overall Safety Strategy
Using the LFIM mask in tandem with F‑500EA lithium‑ion fire extinguishing systems provides dual-layer protection: active extinguishment plus individual breathing safety during evacuation or intervention .
- Mask for smoke: The LFIM is not just any mask for smoke; it’s optimized specifically for the toxic smoke of lithium‑ion battery fires.
- Firefighter gas mask: Engineered to meet the needs of firefighters and trained responders dealing with battery fire hazards.
- Lithium Fire Intervention Mask: The LFIM name itself embodies this blog’s focus: a specialized safety device for lithium‑battery emergencies.
In Summary
The Lithium Fire Intervention Mask (LFIM) is a purpose-built protective device, designed to defend trained users against the unique hazards of lithium‑ion battery fires. With certification to high European safety standards, 15 minutes of filtered breathing, and protection against toxic gases, smoke, and particles, it fills a critical gap in current fire safety gear. Ideal for fire professionals, emergency wardens, facility staff, and any high-risk lithium battery environments, the LFIM integrates seamlessly into a comprehensive lithium‑fire safety protocol.
Equip teams, elevate safety, and build peace of mind; with the LFIM, the mask made for smoke and lithium fire protection.
