WARNING
Welding, grinding, or drilling on the blast
machine could weaken the vessel. Compressed
air pressure could cause a weakened blast
machine to rupture, resulting in death or
serious injury. Welding, grinding, or drilling on
the blast machine vessel, without a National
Board R stamp voids the ASME and National
Board certification.
1.3.3 All welding repairs done on the vessel must be
performed by certified welders, at shops holding a
National Board R Stamp. Welding performed by any
welder not properly qualified per the ASME Code voids
ASME and National Board certification of the vessel.

1.3.4 This blast machine is rated for a maximum
working pressure of 125 psi (pounds per square inch);
do not exceed the rated pressure.
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.
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
and comply with OSHA
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
