SAFETY AND HEALTH CONSIDERATIONS Before opening tank be sure that it is not pressurized. Be sure that the gauge reads”0 PSI”. Depressurize the tank before opening it by exhausting pressure through the abrasive gun (#24). Disconnect the air compressor before opening tank. Protect yourself and those around you from “overspray”. Remember that your portable abrasive blaster is shooting a powerful spray of abrasive material. Do not point it at yourself or anyone around you. Wear a filter
