Often steel cylinders are used to store water. Are there any special requirements in regard of an inner lining of such cylinders?
First of all the cylinders should in this respect be in accordance with the requirements for hand extinguishers and cylinders for gas extinguishing systems. Secondly the life time of the cylinders should be proven to be significantly longer than the date of expire which should be clearly marked on the cylinder, and the customers should clearly be made aware of through instructions and marking etc. that the cylinders should be changed with new ones before the expire date. Also, the people responsible for the servicing of systems should be made aware of this aspect.
