a rather lengthy treatise on the Susceptibility of Electric Matches/ Electrical Igniters to ESD, Lightning and
Electromagnetic Fields

 
for anyone who is interested

ok that link appears a little tricky......
 
go to google and search for Susceptibility of Electric Matches/ Electrical Igniters to ESD, Lightning and

At present. I am more concerned about their sensitivity to ignition by crushing.

Must admit that, though it's interesting it doesn't look at real world conditions. I've heard aboutabout incidents where friction ignition was blamed, but I've never heard of anything about incidents where static was considered a source of unplanned ignition

i think thermitic head compositions, possibly used by foti,

appear less sensitive to friction.......don't know about crushing though

but friction and crushing may in some complicated way be related

ICI used to make ignitors in a strong plastic tube you could tread on them and the compound was far enough back to make friction very unlikely

The usual issue is cost. If the Chinese can get adequate igniters here for under 15p each for sale at 20p +VAT then how is a British company going to make anything cheaper.
