Food industry
The FN-20 and FN-30 are specifically designed for food packaging and storage. They are used in modified atmosphere packaging (MAP), where a gas mixture replaces the air around the product. Carbon dioxide inhibits microbial growth and nitrogen displaces oxygen, reducing oxidation and extending shelf life. The mixture ratio is selected according to the type of product: FN-20 is suitable for more delicate products, while FN-30 offers a stronger preserving effect for meat products, for example.

Laboratories and calibration
FN-20 and FN-30 can also be used as test gases and calibration gases to verify the accuracy of measuring instruments. Their well-defined compositions and stable properties make them suitable calibration gases for analytical and quality control applications.

Available grades:
Food industry grade gas FN-20/FN-30

Packaging:
FN-20 and FN-30 gases are available in cylinders and cylinder batteries.

Gases behave differently depending on their quality and state. Always consult the product’s safety data sheet before using the product. A safety data sheet is a document that conveys information about the properties, risks and safe use of a substance or mixture for industrial or professional use.

Risk of suffocation
An increase in the concentration of FN-20, FN-30 gases in the breathing air may cause a risk of asphyxiation. Asphyxiation occurs unnoticed and can be fatal.

First aid
The person suffering from oxygen deficiency must be immediately evacuated to fresh air. If the victim is having difficulty breathing or is not breathing, administer artificial respiration as quickly as possible and call for help. When rescuing a victim, it is important to remember not to enter an oxygen-deprived area without breathing equipment.

Access
– When handling the substance, follow the instructions and safe working practices given
– The gas handler must be properly trained
– Use only carefully checked pressure regulators and other operating equipment suitable for this gas. If in doubt, contact Woikoske.
– Open the valve slowly to avoid pressure shock
– The valve is opened and closed by hand. The use of assistive devices is prohibited!
– It takes about one turn to open the bottle.
– The cylinder in use must be properly secured.
– Keep the valve outlets clean!
– Close the cylinder valve after each use and when the cylinder is empty.
– Always report damaged valves and cylinders to Woikoske.

Transport
– The driver must be aware of the potential dangers of the load and know his duties in the event of accidents and incidents.
– Liquid nitrogen must be carried in open vehicles with the load compartment isolated from the cab
– The transport of gas cylinders shall be carried in an upright position
– The load must be secured
– Cylinders must not be knocked, thrown or dropped from the vehicle platform
– Attention to ADR regulations during transport

Storage
– Observe all legal and local requirements for the storage of cylinders.
– Store cylinders in a well ventilated area
– Cylinders should not be stored in conditions that promote corrosion
– Cylinders are stored upright and secured so that they cannot fall over
– Valve guards must be in place AT ALL TIMES
– Empty and full cylinders to be kept separate
