Storage & Safety

· Store in a cool, dry, well-ventilated area away from heat and direct sunlight.

· Keep cylinders upright and secured to prevent falling or damage.

· Do not store near oxidizers or flammable gases.

· Krypton is nonflammable and non-toxic, but high concentrations may displace oxygen and cause asphyxiation.

· Use only in well-ventilated areas.

· Do not attempt to modify, repair, or refill cylinders without authorization.

· Always use a suitable pressure regulator designed for inert gas service.

· Keep cylinder caps in place when cylinders are not in use.

For detailed handling and emergency information, please download the SDS.
