  Manual No. 24813 

 

 

 WARNING 

Excessive compressed air pressure could 
cause a blast machine to rupture. To prevent 
serious injury or death, do not exceed the rated 
pressure of the blast machine vessel. 

 

1.3.5

 

OSHA does not require pressure relief valves on 

blast machines when air compressors supplying air to 
the blast machines are built to ASME

(1)

 specifications 

and comply with OSHA

(2)

 regulations. ASME Manual 

section VIII, Division 1, UG-125, paragraph A90 (g) 
states that pressure relief valves or protective devices 

"...need not be installed directly on a pressure 
vessel when the source of pressure is external to 
the vessel and is under such positive control that 
the pressure in the vessel cannot exceed the 
maximum allowable working pressure at the 
operating temperature..."

. OSHA regulation 1910.169 

refers to the above ASME code when describing the 
necessity of pressure relief valves on compressed air 
equipment. 

DO NOT

 operate blast machines with air 

compressors that are not equipped with properly 
functioning pressure relief valves.

Subpart M - Compressed Gas and Compressed Air Equipment. 

 

1.3.6 Remote 

Controls 

 
1.3.6.1 

The blast machine is equipped with remote 

controls that pressurize and depressurize the blast 
machine. Pressurization, which starts blasting, occurs 
when the operator presses the control handle lever 
located near the nozzle. Depressurization, which stops 
blasting, occurs when the operator releases the control 
handle lever. 
 

1.3.6.2

 A remote control system is an OSHA-required 

safety device. The control handle, located near the blast 
nozzle, is the activator for the remote control system. 
When the operator intentionally or unintentionally 
removes hand-held pressure from the control handle, 
the machine depressurizes, stopping air and abrasive 
flow through the nozzle. The remote control system "fails 
to safe", which means any interruption in the control-air 
circuit, deactivates the blast machine.

 

 

 

WARNING 

Never modify or substitute remote control 
parts. Parts from other manufacturers are not 
compatible with Clemco equipment. If ANY part 
of the remote control system is altered, 
involuntary activation, which may cause 
serious injury, can occur.
