With the increasing use of electric power in today’s cars, boats, and ships, the likelihood of fires in lithium-ion batteries increase proportionally. Fires in these battery types not only generates immense heat, but also the extremely toxic gas Hydrogen fluoride. Mixed with water hydrofluoric acid is created. Both the gas and acid easily penetrate skin and muscles and often even pass barriers of commonly used PPE, with the result of damaged tissue and cell membranes.
Safenor is currently working on putting together a complete portable system for all kinds of emergency services. Individual units are already available for purchase.
Experience has shown that F-paper is one of the most reliable and low cost alternatives in terms of detecting hydrofluoric acid.
This small sheet of paper can be attached to the visor of a full face mask or on the visor of full body protection suit. In order to detect hydrofluoric acid present on surfaces it’s beneficial to use a 1M hydrochloric acid solution instead of distilled water as it gains a clearer result.
The paper initially has a light pink colour that changes to light yellow when the acid is present.
The package contains 200 sheets. A newer version with an adhesive part will soon be launched.
