Learn how to safely use and place the BDS MK5 fire suppression aerosol. Follow our step-by-step guide for vehicle and tactical placement, plus common mistakes to avoid.
Quick answer
To use the BDS MK5 fire suppression aerosol safely, mount it where you can reach it instantly with a gloved hand, pull the orange finger loop to activate, and aim the discharge at the base of the fire. Placement matters as much as technique: keep it secure, accessible, and away from direct heat.
Why placement is critical for tactical vehicle fire suppression
In a vehicle or tactical setting, seconds matter. The MK5 is designed to be quickly accessible, but where you mount it determines whether you can grab it without fumbling. A common mistake is mounting it in a spot that requires unbuckling or reaching across your body. Instead, choose a location that is within arm's reach from your seated position, such as on the door panel, dashboard, or center console, using a dedicated mount or pouch.
Also consider the environment: avoid mounting directly in front of a heater vent or in direct sunlight, as extreme temperatures can affect aerosol performance. The MK5's compact size allows it to fit in many M4-sized pouches, giving you flexibility for both vehicle and vest-mounted carry.
When the MK5 is the right tool—and when it isn't
The BDS MK5 is ideal for rapid knockdown of small fires in confined spaces, such as engine compartments or vehicle interiors. However, it is not a substitute for a full-sized extinguisher in large, open areas or for fighting a well-developed fire. For confined-space knockdown, the aerosol format excels because it leaves no residue and is easy to deploy. If you need a tool for larger spaces, consider a larger unit or a traditional extinguisher.
Additionally, the MK5 is designed for one-time use. Once discharged, it must be replaced. Keep that in mind when deciding how many units to carry—especially in a vehicle where you might need more than one for different fire scenarios.
Step-by-step: Safe use and placement of the BDS MK5
- Choose a secure, accessible mounting location: Select a spot within arm's reach from your normal seated position, such as the door panel or center console, and use a dedicated MK5 rigid case or pouch to keep it secure. Avoid areas near direct heat sources or where it could become a projectile in a crash. Check that you can grab it without unbuckling or stretching.
- Inspect the unit before stowing: Verify the orange pull tab is intact and the unit is not damaged. Ensure the finger loop is easily accessible and not tangled with other gear. A damaged or obstructed unit may fail when needed.
- Practice your draw: With the unit secured, practice reaching for it and slipping your finger through the loop while wearing gloves. This builds muscle memory for stress situations. If you can't draw it smoothly in practice, reposition the mount.
- Aim at the base of the fire: When deploying, pull the finger loop to activate and direct the discharge at the base of the flames, not the smoke. Keep a safe distance and ensure you have an exit route. Never discharge into the air; aim low and sweep if needed.
- Dispose of the unit properly after use: Once discharged, the unit cannot be reused. Follow local regulations for disposal and replace it with a new MK5 immediately. Mark the replacement date on your calendar or inventory list.
