A customer of mine had a new 6kg powder fire extinguisher in its cardboard box in the back of his van. The fire extinguisher was not installed in its holder as per its instructions. It just slid about in the back of the van bumping about as the van hit pot holes.
Unexpectedly the extinguisher automatically discharged filling the van with powder while my customer was driving it. The customer's old dad was in the van at the time as a passenger, and it was difficult getting him out quickly from the powder laden air inside the van. Both men had to attend hospital to be checked over.
A lesson to be learned there I think.
