A three car garage full of acetelyne would make a helluva explosion.
Regulators don't typically fail the way you describe. I expect the hose has a leak at a fitting or the torch leaks but the regulator back has a vent that can be tested. Some soapy water makes a good leak detector solution. If you aren't familiar or have not recently read-up on acetylene-oxygen safety, here is a good link: http://www.esabna.com/euweb/oxy_handbook/589oxy1_1.htm
