You may also be interested to know that the updated British Standard 5306-8:2012 Selection and positioning of portable fire extinguishers Ã¢â‚¬â€œ Code of Practice states as follows.
"5.4.3 Use of powder extinguishers The discharge of a powder extinguisher within buildings can cause a sudden reduction of visibility and can also impair breathing, which could temporarily jeopardize escape, rescue or other emergency action. For this reason, powder extinguishers should generally not be specified for use indoors, unless mitigated by a health and safety risk assessment."
Additionally, when looking to comply with Part 8 of the ADR regulations, ensure you meet the minimum dry powder fire extinguisher provision to suit the size of your vehicle.
