Safety cabinets for the storage of pressurised gas cylinders in accordance with DIN EN 14470-2 must be designed and constructed in such a way that in case of fire, no additional risks of the fire spreading result from the content. The fire resistance should enable employees to leave the working area and allow the fire brigade to reach the area and contain the fire before the pressurised gas cylinders become unstable. Minor amounts of escaping gas within the cabinet must be extracted to protect health and prevent explosions.
