Paint, plastic, carpets, paper all go. Masonry block walls become unstable
when exposed to fire and ff's must set up a collapse zone. Wooden trusses at
the joint plates fail catastrophically. Sometimes you will see a triangle by
the main door with a R or F in it showing trusses.
Yup, that's the sad fact that most people don't realize. Despite
building construction standards most materials will deteriorate when
exposed to intense heat for a prolonged period of time. Having been a
full time firefighter for 28 years (now retired for some years) I'm a
strong believer in automatic sprinkler systems in all buildings
including single family residences. The NFPA standards are there and
have been for years. What needs to be done now is to convince people
that it's in their best interest to have sprinklers which would prevent
a hell of a lot of residential and other fire related deaths each year.
I was just moving things, looking at an extinguisher. Took it out back and
sprayed. Shoots out a strong stream of liquid. Not for electrical it says.
I'm not going to squirt it at a grease stove fire. AB rated. No guage
