The "1:10 rule" for acetylene refers to the safety guideline that acetylene gas should never be used at pressures above 15 psi (pounds per square inch) or allowed to accumulate in concentrations above 10% in air. Exceeding these limits increases the risk of explosive decomposition, as acetylene becomes unstable and highly dangerous under higher pressures or concentrations.
