Coming Soon! - First Ever To Formally Pass UL 5800 Class 2 & Class 3 Containment Bags - Performance Level 1 (Total Containment Rating)

Our Story

Deep Three Inc, parent company to Brimstone Fire Protection, was founded in 2013. We are a family oriented company and find satisfaction in helping others reduce the risk in their lives. We originally developed a line of fire proof storage bags, but shortly after entering the market Lithium-Ion battery fires were starting to make the news. Understanding Lithium-ion thermal runaways are much more difficult to fight than traditional fires, we felt containment seemed a likely solution, should a fire occur on board an aircraft, a sea faring vessel, or inside a building with limited exterior access.  

We were already using various materials necessary to withstand tremendous heat, so in 2015 we hired a team of engineers and spent many, many hours developing and testing the products which would lay the foundation for our successful entry into the Lithium-Ion battery fire containment industry. We were able to bring our fire containment bags into the market about 1 year before the Samsung S7 phone started having battery issues. The Samsung Note 7 Smartphone alone had 92 fires reported within weeks of it's release. These reports include severe cases: 26 burns, and 55 instances of property damage. This massive recall is what really awakened the general public to what a potential threat storing so much energy into such compact devices could create. We immediately began to see a huge leap in orders from companies and Government agencies around the world and continue to grow as demand dictates (2022 has seen our best sales YTD with no slowdown in sight).
