If you keep concentrations of HCl and H2O2 reasonable there will not
be a problem. Keep your etchant covered when not in use, but not
airtight to avoid pressure buildup.
Keep your chemicals, etchant and especially the HCl, in a second
container to catch a spill in case of breakage. Note that plastic
bottles of HCl will allow small amounts of HCl to pass through the
plastic, corroding very closeby metal parts. Put in a second larger
container or glass bottle to avoid that.
Regarding the temperature, -10 what? Shivers per second? This is an
international forum please give a unit or half of the people will
misunderstand.

> Can anyone spot any hazards of etching at home in a garage? My choice of etchant would be the HCL H202. I am worried about possible vapors passing into the house and also the effect of corrosion on my car and my metal garage doors. The temperatures in my garage can get as low as -10. Any pointers or cautions would be much appreciated.
