BS5839 or HTM 05 Fire Safety

Afternoon All


Hopefully there is someone out there to provide some advice as I am somewhat stumped on this topic....


Can anyone advise whether BS5839 takes precedence over HTM 05, or, visa versa?


Currently working on a project and the incumbent fire alarm specialist is adamant that the HTM's take precedence, but, the Fire Officer believes that the BS does.


Cheers as always for any opinions and advice.


Regards


Adrian.

  • I think the fire officer is referring to 5839-1 2013 which required protection in voids over 800mm full stop.The 2017 version no longer requires protection providing the void has an appropriately low fire risk. By the same token the most recent version now requires consideration of protection in voids less than 800mm where a fire risk assessment determines it appropriate. Voids over 1500mm should be treated as rooms.
