BUY CO2 SPECIAL EFFECT MACHINES

Yes, the use of CO₂ machines indoors is completely safe when the appropriate measures are followed:

• Ventilation: Ensure that the space has natural or forced ventilation.
• Minimum space: We recommend a minimum of 100m² with ceilings at least 3 metres high.
• Duration: Avoid prolonged continuous use (more than 30 minutes at a time).
• Supervision: Always have technical personnel present during use.
• Detection: In small enclosed spaces, consider CO₂ detectors.

• Never direct the jet directly at people.
• Maintain a minimum distance of 2 metres from the public.
• Use in short bursts (5-10 seconds maximum).
• Check that there are no people in the area who are allergic to extreme cold.
• Store bottles upright in a cool place.

CO₂ is a natural and harmless gas in the concentrations used for special effects. However:

• Avoid direct inhalation of concentrated gas.
• People with respiratory problems should stay away.
• Extremely cold temperatures can cause frostbite if there is direct contact.

The duration depends on several factors:

Portable spray guns (0.5kg bottle):

• Intermittent use: 15-20 sprays of 3-5 seconds.
• Continuous use: approximately 2-3 minutes.

Professional jets (5kg cylinder):

• Intermittent use: 150-200 activations lasting 5 seconds.
• Continuous use: approximately 15-20 minutes.

High-power jets (10kg bottle):

• Intermittent use: 300-400 short activations.
• Continuous use: approximately 25-35 minutes.

Factors affecting consumption:

• Ambient temperature (higher consumption in hot climates).
• Equipment power.
• Duration of each activation.
• Cylinder pressure.

Here is a guide to help you calculate your needs:

• Concert (2 hours): 2-3 10kg bottles.
• Corporate event (3-4 hours): 1-2 5kg bottles.
• Theatre/show (1.5 hours): 1 5kg bottle.
