This checklist is not all-inclusive. You should add to it or delete items that do not apply to your business; however, carefully consider each item and make your decision. You should refer to Minnesota statutes and rules, and federal OSHA standards adopted by reference in Minnesota for specific guidance that may apply to your work situation (see www.dli.mn.gov/). (Note: This checklist is typical for general industry but not for construction or maritime industries.)
- Is every receiver equipped with a pressure gauge and one or more automatic, springloaded safety valves?
- Is the total relieving capacity of the safety valve able to prevent pressure in the receiver from exceeding the maximum allowable working pressure of the receiver by more than 10 percent?
- Is every air receiver provided with a drain pipe and valve at the lowest point for the removal of accumulated oil and water?
- Are compressed air receivers periodically drained of moisture and oil?
- Are all safety valves tested at regular intervals to determine whether they are in good operating condition?
- Is there a current operating permit?
- Is the inlet of air receivers and piping systems kept free of accumulated oil and carbonaceous materials?
