SECTION 1

SAFETY GUIDELINES

The SDI Select™ 60 is safe and easy to operate; however, certain precautions must be followed
during its use. To understand all the necessary precautions, you must read the entire SDI Select 60
manual before operating the unit.

The SDI Select 60 should only be operated by authorized and trained personnel.

GENERAL SAFETY REQUIREMENTS

• Always wear personal protective equipment including safety glasses, gloves, and 32+NRR ear

plugs and ear muffs.

• Always operate the SDI Select 60 with protective clothing to cover all exposed skin.

• Always direct the blast stream in a safe direction. Never direct the blast stream at yourself or others.

• Never use a wire tie to hold the applicator trigger in the ON position. Doing so violates safety

regulations, can damage the applicator and voids warranty coverage of the applicator.

• Always turn source air OFF and bleed down the system before disconnecting the air supply hose.

• Always turn source air OFF and remove the applicator control line before removing the blast hose.

• Always follow all of the governing codes of your local/national body.

• Always ensure the finger guard over the feeder exhaust port is installed. The finger guard on the

feeder protects from a potential personal injury site located inside the SDI Select 60.

• Always ensure all panels are installed before operating.

• Only operate the SDI Select 60 at or below the recommended hose or blasting unit pressure levels.

• Always ensure the blast hose is free of kinks.

• Always ensure that both ends of all hoses are properly attached and tightened before

pressurizing any hoses.

• Always electrostatic ground the material being cleaned.

• Always ensure hoses and tubes are free of nicks and gouges.

• Always repair any damage to the SDI Select 60 before attempting to start or operate the unit.

• Always ensure the ventilation holes are free of obstruction.

• Always wear gloves to protect hands from exposure to cryogenic temperatures and sharp blade

surfaces.

ELECTROSTATIC DISCHARGE

Static discharge may ignite flammables.

Electrostatic discharge can be hazardous to the operator and the equipment. The static charge of

varies with the amount of dry ice and humidity present.

CO

2

GROUND THE MATERIAL BEING CLEANED

Always ground the material being cleaned to assure safe operation while blasting.

1. Know your environment.

• Electrostatic buildup changes as humidity levels change and will vary by location.
Electrostatic discharge is higher at low humidity levels and occurs most often during
winter.

2. Attach static bond cable.

• To minimize electrostatic buildup between the part being cleaned and the
applicator, attach the static bond cable between the target surface and the blast hose
connection or to an electrically conductive supporting structure. Use a conductivity
tester for confirmation.

3. Plug into a grounded power outlet.

• This step is critical for electrostatic dissipation. If the ground is not connected, a
charge may build up on the unit or the applicator.

CO2 SAFETY

• The SDI Select 60 uses solid state carbon dioxide (CO2). CO2 is nontoxic, non-corrosive and
nonconductive. It is approved by the FDA and USDA.

• Solid CO
CO

• Vapor CO
the SDI Select 60 with a proper ventilation system that maintains the concentration levels of
the governing codes of your local/national body.

• Always review and observe all safety guidelines when using materials that displace oxygen.

• All operators and supervisors should familiarize themselves with the literature on the
physiological characteristics of CO
obtained from the governing codes of your local/national body.

• Always use a CO
