Homebrew PCBs

I must echo the views of dangerous chemicals. A school friend was working on
cleaning his motor bike engine. He was using a mixture of acetone, white
spirit and trichloro??? . His father was using a grinder about 25 -30 feet
away in the same garage. All of a sudden my friends overalls caught fire
from the exposed splashed on chemicals. His hands were the worst burnt as he
tried to take his burning overalls off. 18 months in hospital, 2 to 3 years
of occupational therapy. 5 years before he was able to have assisted work.
He needs repeated surgery as the scars on his hands shrank. The burning
pants and underpants destroyed any chance of sex again, all gone or scar
tissue.

 

I do use some of the above chemicals but made myself a fume cupboard/ paint
spray booth and have a couple of fans to draw the fumes through to an
outside widow and roof vent. I also have a small fire extinguisher in my
work area (I do white metal casting as well) and under the kitchen sink.
Never used them, except when they have date expired and have been replaced.
A couple of times I started a fire in the backyard or BBQ and put it out
with the out of date expired extinguisher. A useful learning experience.

 

 

I am a dentist and have work made form me by dental technicians. Many of the
chemical the dental technicians use are nasty. I am aware that most of the
dental technicians I used to know have died in their middle years and looked
older than they should. I wondered if this was continual exposure to
chemicals. I was visiting one dental laboratory where the fumes were
overpowering and left the room almost immediately. There were 5 technicians
in the room all day at the time. Only technician was older than me at the
time. I know that at least 3 of them have died and the female never carried
a child to term. This was 25 to 30 years ago. 

 

 

The chemicals are useful but please treat them respect or use alternatives.
