Fire Blanket




I've been doing a little research for an up-coming article on firefighting for cruisers.

Fire prevention is the first step. I experienced a number of incipient fires in the refinery over the years and one on a boat and they all shared a common cause; chafed wire or by extension, a bad switch. Two were complicated by running the wires through the same pass-through as fuel lines; common practice, but really dumb.

I moved on to fire blankets. Not mentioned as often, rare in chandleries, but one of the best proven and simple items. Very difficult to make things worse and it will always slow the progression while you gather more materials. So I went in the basement to gather a few materials for a test; glass cloth, cotton rags, and some scraps of wool. Pulled out a torch and within a few minutes of testing came to an embarrassing "ah-ha moment:"


Army Surplus wool blankets are fire retardant treated and won't burn. Of course they are treated. It's a war.

So if you've got an old blanket or three in the trunk, like many of us do, now you know what it's good for.

Wasn't that obvious?

Wool is actually preferred for first responders and most industrial use because it is better for wrapping people and drapes better over the fire. However, fiberglass is common for house hold use because it fits in a smaller package. I'm going to make a cover for the Army blanket and use that. It really would not burn.
