OAW Safety Issue
C2H2is physically unstable at pressures much above 15 lb/in2(about 1 atm)
Storage cylinders are packed with porous filler material saturated with acetone (CH3COCH3)
Acetone dissolves about 25 times its own volume of acetylene
Different screw threads are standard on C2H2and O2cylinders and hoses to avoid accidental connection of wrong gases
