SAFETY PRECAUTIONS AND WARNINGS
User’s Guide Information
Dry ice cleaning equipment should not be operated without proper training and the
consent of your direct supervisor or management. The information contained in the
User’s Guide will provide all the tools necessary for proper operation, safety,
maintenance, and troubleshooting of the equipment. Read and understand the contents of
this guide before using or servicing your machine.
Equipment Usage
Your new cleaning system was designed for use in an industrial environment. Proper safety precautions
should be practiced, observed, and monitored at all times. Be especially careful when blasting around
materials that can shatter. Dry ice blasting adapts to many types of applications, but the high velocity
pellets can cause damage to fragile items or substrates of low integrity. Remember NEVER to direct the
blast stream at yourself or others.
Asphyxiation Hazard
Sublimation of dry ice creates CO
2
gas. This gas is 40% heavier than air, and thus
displaces oxygen in low-lying areas and enclosed spaces. When blasting, always have
adequate ventilation in and around your workspace. Contaminated compressed air (or
nitrogen) used as a propellant may greatly increase respiratory risk. A “High CO
2
”
sensor/monitor with indicators is a worthwhile investment and can help prevent
accidental asphyxiation.
Noise
Blasting equipment generates a high velocity air flow from the nozzle. This air flow creates friction as it
passes through normal static air, resulting in high decibel noise levels. Though these levels can be
controlled somewhat by altering pressures and flow rates, ear protection is required in all blasting
situations. Additional noise factors include the object being cleaned, distance from the targeted material,
media quantity being used (ice rate), and acoustic surroundings. If you are unsure about blasting in an area
around you or fellow co-workers, consult with your safety director for advice and/or safety parameters
before beginning work.
Emergency Stop Mechanisms
Your unit is equipped with an Arm/Disarm switch located in the center of the control panel. Under normal
use, this switch acts as a convenient way to quickly interrupt power to your PHX-150. However, the true
designated E-STOP is the full-flow valve (bright yellow with a red handle) located on the air system
manifold under the control panel. This valve must be closed before attempting maintenance work or
repairs. A 5/16” hole is provided in the handle to accommodate your company lockout procedures, if
applicable. Raise the locking tab to re-open the valve.
Protective Gear
Before beginning work, make sure you have the proper protective gear for the job. This
includes the basics: Ear plugs or muffs (or both), eye protection, gloves, long sleeves,
long pants, and safety shoes. Dependant upon specialized cleaning jobs, you may also
need other protective items such as: self-contained breathing apparatus, respirator,
grounding straps, skin protectors, jumpsuit, special clothing, or other equipment as
deemed necessary by your company’s safety regulations.
