WARNING
The compressor must provide adequate output,
and the plumbing between the compressor and
the point of attaching the respirator hose must
have sufficient capacity to supply the volume of
air at the pressure required (as stated in Section
4.2.2). Restricted air flow will cause discomfort to
the user, and may result in ingress of hazardous
and toxic dust, subjecting the user to health and
life threatening toxic poisoning and long term
respiratory disease and death.
5.0 OPERATION
WARNING
With the respirator on, leave the blast area
immediately if any of the following conditions
occur:
• Any part of the respirator system becomes
damaged.
• Any air monitoring alarm is activated.
• Airflow into the respirator is reduced or
stops.
• Breathing becomes difficult.
• At the first sign of dizziness, nausea, fever,
illness or injury.
• Any contamination is noted by taste, smell
or vision inside the respirator.
• Vision becomes impaired.
• Any irritation is noted.
5.1 Prior to operation, thoroughly inspect and clean
the helmet, breathing tube, respirator hose, air entry ports,
and fittings of all dust and debris. Inspect the helmet
suspension and adjust if necessary per Section 6.2.
5.2 Start the compressor and open the service valve
to pressurize the air supply line.
5.3 Check air pressure at the point of attachment. Set
the pressure between the minimum pressure assigned in
Section 4.2.4 and the maximum of 100 psi. Pressure must
be set with the respirator connected.
5.4 Check all safety, and breathing equipment used in
conjunction with the respirator as recommended by the
manufacturer.
5.5 Check respirator hoses and connections for tight-
ness and leaks.
5.6 Put the respirator on in a clean non-hazardous
environment, free of contaminants, where the air is safe to
breathe. When putting the respirator on or taking it off,
keep it upright to prevent dust and abrasive from falling
inside.
5.7 Position the chin strap so it fits comfortably under
the chin.
5.8 Position the knit cuff on the inner collar so that it fits
snugly around the neck in turtleneck fashion, without any
interference from clothing such as shirt collars. When
correctly positioned the smaller elastic end of the collar
must face up.
