Are compressors operated and lubricated in accordance with the manufacturer's recommendations?
Are safety devices on compressed air systems checked frequently?
Before any repair work is done on the pressure system of a compressor, is the pressure bled off and the
system locked-out?
Are signs posted to warn of the automatic starting feature of the compressors?
Is the belt drive system totally enclosed to provide protection for the front, back, top, and sides?
Is it strictly prohibited to direct compressed air towards a person?
Are employees prohibited from using highly compressed air for cleaning purposes?
If compressed air is used for cleaning off clothing, is the pressure reduced to less than 10 psi?
When using compressed air for cleaning, do employees use personal protective equipment?
Are safety chains or other suitable locking devices used at couplings of high pressure hose lines where a
connection failure would create a hazard?
Before compressed air is used to empty containers of liquid, is the safe working pressure of the container
checked?
When compressed air is used with abrasive blast cleaning equipment, is the operating valve a type that must
be held open manually?
When compressed air is used to inflate auto tires, is a clip-on chuck and an inline regulator preset to 40 psi
required?
Is it prohibited to use compressed air to clean up or move combustible dust if such action could cause the dust
to be suspended in the air and cause a fire or explosion hazard?
COMPRESSED AIR RECEIVERS
Is every receiver equipped with a pressure gauge and with one or more automatic, spring-loaded safety
valves?
Is the total relieving capacity of the safety valve capable of preventing 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 drainpipe 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 frequently and at regular intervals to determine whether they are in good operating
condition?
Is there a current operating permit issued by the Division of Occupational Safety and Health?
Is the inlet of air receivers and piping systems kept free of accumulated oil and carbonaceous materials?
COMPRESSED GAS & CYLINDERS
Are cylinders with a water weight capacity over 30 pounds equipped with means for connecting a valve
protector device, or with a collar or recess to protect the valve?
Are cylinders legibly marked to clearly identify the gas contained?
Are compressed gas cylinders stored in areas which are protected from external heat sources such as flame
impingement, intense radiant heat, electric arcs, or high temperature lines?
Are cylinders located or stored in areas where they will not be damaged by passing or falling objects, or
subject to tampering by unauthorized persons?
Are cylinders stored or transported in a manner to prevent them creating a hazard by tipping, falling or rolling?
Are cylinders containing liquefied fuel gas, stored or transported in a position so that the safety relief device is
always in direct contact with the vapor space in the cylinder?
Are valve protectors always placed on cylinders when the cylinders are not in use or connected for use?
Are all valves closed off before a cylinder is moved, when the cylinder is empty, and at the completion of each
job?
Are low pressure fuel-gas cylinders checked periodically for corrosion, general distortion, cracks, or any other
defect that might indicate a weakness or render it unfit for service?
Does the periodic check of low pressure fuel-gas cylinders include a close inspection of the cylinders' bottom?
