Hi, please advise of the correct fire extinguisher to be located in an Oxygen store room where usually 20 cylinders are kept.

Oxygen itself is not flammable, it makes other materials more readily ignitable and makes them burn more fiercely & quickly. Your extinguisher provision should be suitable for the risks in the nearby area, although a correctly designed oxygen store should contain no combustible materials or ignition sources.

Your aim should be to prevent an oxygen fuelled fire occurring - realistically if these cylinders are involved in a fire it's a case of raise the alarm, evacuate and leave it to the fire brigade.

For general cover in healthcare premises you should never use powder and instead have fire points of water spray & CO2 or to make things simpler fire points of just water mist extinguishers - all available from this host site.
