2. Sigurnosne informacije

WARNING: Liquid Nitrogen (LN2) is extremely cold (-196°C / -320°F) and can cause severe frostbite or cryogenic burns upon contact with skin or eyes. Always handle LN2 with extreme caution and wear appropriate personal protective equipment (PPE).

• Always wear cryogenic protective gloves, a face shield or safety glasses, and long-sleeved clothing when handling liquid nitrogen or operating the sprayer.
• Use in a well-ventilated area to prevent oxygen displacement, which can lead to asphyxiation. LN2 rapidly vaporizes into gaseous nitrogen, which is an inert gas.
• Do not store liquid nitrogen in sealed containers, as pressure buildup can cause an explosion. This sprayer is not designed for prolonged storage of LN2.
• Avoid direct contact of LN2 with skin, eyes, or clothing. If contact occurs, immediately flush the affected area with lukewarm water and seek medical attention.
• Keep the sprayer upright during transport and operation to prevent spills.
• Ensure the sprayer is empty and depressurized before attempting any maintenance or cleaning.
• This product does not come with liquid nitrogen. LN2 must be purchased separately from a qualified supplier.
