[TheForge] Gas forge safety?

[theforge@mailman.qth.net]

Fan blown gas safety:
(1) Write to the manufacturer, or go online, to obtain their own instruction 
manual. If there is a flame-guard safety system installed, check to see that 
it is working.
(2) With the system pressurized, employ first your sense of smell, and then 
soapy water, to check the whole incoming gas system for leaks before operating.
(3) Always turn the blower fan on before opening the gas cock.
(4) Use a good ignition source (i.e., plumbing torch) to supply continuous 
flame until the furnace is lit; keep your hand and arm along with anything else 
combustible, out of the exhaust path.
(5) Never leave the area while the equipment is running. 
     Never leave the area until a proper shutdown and complete cooling has 
been accomplished. Use a drop of water--not your hand--to establish 
temperatures. 
     Never let your attention wander completely from the furnace while it is 
running--especially while you are familiarizing yourself with the equipment.
(6) Consider what you would wish you had available in case of an accident and 
make sure it is on hand right now. The local fire department will give you 
good advice here.
(7) Proper shutdown begins with the gas valve closest to the supply source, 
and then each valve downstream from it (regulators, needle valves, final valve) 
in that order, so that positive pressure is eliminated, while a pure fuel gas 
atmosphere is maintained. Whatever else is needed depends on the particular 
system (see step 1). 
  Safety depends on complete, calm, understanding. It is never established by 
fear.
