National foreword National foreword National foreword
The national foreword has been revised and references are made to the special requirements for life safety. The UK normal practice of reserving sprinkler system water supplies solely for the sprinkler system is referred to and it should be assumed that this reference in the national foreword relates to the Note at 9.6.4, although this is not stated
We recommended that LPC rules users read the National foreword.

TB203. 3.2.2 Review of hazard (Quarterly)(Quarterly)(Quarterly)(Quarterly)
The Technical Bulletin specifies that the quarterly review of hazard should be undertaken by one of the following procedures:
• An inspection by a competent person for example an engineer from a sprinkler servicing contractor; or
• By the sprinkler system user submitting a return to the sprinkler contractor detailing any changes
A list of items to check during the review of hazard is given in the TB, see below:

FPA, November 2009 Page 26
If any changes are identified that might change the effectiveness of the sprinkler protection remedial action should be taken immediately.
The yearly review of hazard is detailed as follows:
The frequencies of maintenance tasks and in some instances changes to frequencies are illustrated below8:
