The fireman switch is a specialized switch disconnector/isolator. These switches can often be seen on the outside wall of shops, industries or commercial buildings. They are used by firemen to turn off neon lighting or other electrical equipment in case of fire to prevent the overheated equipment from exploding. To be effective and safe, they should:

Be robust & reliable design in non-flammable material like aluminum.
Be a highly visible color, like red
Have clearly indicated on & off positions on the front side
Have an operating handle is designed in such a way that a fireman-hook or axe can be used to switch off
To reset, a so-called "two hands grip" must be used for safety reasons. The interlocking mechanism prevents accidental maneuvers
Be easy to install and to operate. Possible to add on an auxiliary contact.
(In the UK) They must comply with IEC 60947-3 and BS 7671.^[1]
