Specifications and Guidelines

For the operation of this system the following regulations and directives are applicable in the Federal Republic of Germany (available from Carl Heymanns Verlag KG, Luxemburger Straße 449, 50939 Cologne):

• BGV D 26 Spray jet tasks
• Executing instructions for BGV D 26 – BGR 117 Working in closed rooms
• BGR 189 Using safety gear – BGR 195 Using of safety gloves
• BGR 500 Working with spraying devices – BGI 534 Working in closed rooms
• BGI 836 Gas warner

Safety Devices

Emergency-stop button

If the emergency stop button is pressed, the dry ice dosing is stopped and the air flow from the nozzle is interrupted.

Switch-off in case of emergency

→ Release the trigger of the jet pistol. → Press emergency-stop button.

The dry ice dosing is stopped and the air flow from the nozzle is interrupted.

→ Interrupt the compressed air supply.

Proper use

The machine is used to remove dirt using dry ice pellets that are speeded up using an air jet.

The machine should not be operated in explosive environments.

Use only dry ice pellets as jet medium. Using any other jet medium can cause damage to the machine.

Function

The air pressure reaches the jet pistol via a pressure regulation valve. The valve opens when the trigger of the jet pistol is pressed and the air flow comes out from the jet pistol. Additionally, dry ice pellets are dosaged into the air stream via the dosing device.

With the version "IB 7/40 Advanced" the additional dosing can be switched off at the jet pistol. The dry ice pellets hit the surface to be cleaned and remove the dirt. Additional heat currents are formed between the dirt and the object to be cleaned by the -79 °C cold dry ice pellets; this results in the dirt being loosened. At the same time, dry ice immediately gets coverted into gaseous carbon dioxide on contact and requires 700 times the volume of dry ice. Thus, the dirt penetrated by the dry ice thus gets thrown off.

During the spraying operation through the jet, a vibrator located on the dry ice container ensures continuous sliding of the dry ice pellets.

Safety notes

The device may only be used by persons who have read and understood the operating instructions. All safety notes must be observed.

→ Keep the operating instructions in such a way that they are available to the user at all times.

Hazard levels

⚠️ Danger

Indicates an imminent threat that leads to serious physical injury or death.

Warning

Indicates a potentially dangerous situation that may lead to serious injury or death.

Caution

Indicates a potentially dangerous situation that may lead to minor injury or cause material damage.

Symbols on the device

⚠️ Danger

Risk of injury from flying dry ice pellets. Do not point the jet gun at people. Keep other people away from the work area and keep them away while the machine is in operation (e.g., by restricting access).

Do not touch the nozzle or the dry ice jet during operation.

⚠️ Danger

Risk of poisoning from carbon dioxide. Dry ice pellets consist of solid carbon dioxide. During operation of the device, the amount of carbon dioxide in the air at the workplace increases. Ventilate the workplace sufficiently; if necessary, use a warning device for personnel. Signs of high carbon dioxide concentration in the air:

- 3...5%: Headache, increased breathing rate.

- 7...10%: Headache, vomiting, and possible loss of consciousness.

If these symptoms occur, immediately turn off the device and go out into fresh air; before continuing work, improve ventilation measures or use a breathing apparatus.

Carbon dioxide is heavier than air and accumulates in narrow, low spaces or in closed containers.

Ensure adequate ventilation at the workplace.
