      Why do we need fire and
         life safety codes?
According to the NFPA, in 2007 there
  were…

   530,500 structure fires – one every minute
   3,000 civilian deaths – one every 2.5 hours
   15,350 civilian injuries – one every 30 minutes
   $10,600,000,000 in property damage
   A fire department responded to a fire every 20
    seconds

                                                      Slide 2
      Objectives

   Introduce the codes that drive fire and life
    safety compliance

   Overview of fire detection and suppression

   Provide tools to conduct a basic fire and
    life safety assessment
                                                Slide 3
Fire Regulations and Codes
   Safety and Health Regulations
    – OSHA (29 CFR 1910 & 1926)

   Fire and Life Safety Codes
    – International Building Code (IBC)
    – National Fire Protection Association (NFPA)
    – Municipal Requirements


                                                Slide 4
    Additional Requirements

                                       Slide 5
How are These Codes Enforced
         Codes are adopted by reference by
          ordinance.
         Plans for remodeling or a new
          construction must be approved by
          the authority having jurisdiction
          (AHJ) prior to starting work.
          – State Fire Marshal’s Office
          – Local Fire Department or City Code
            Officials
          – Designated Local AHJ

         Take Home Message – Know what
          code(s) apply to your operation        Slide 6
        Which do I follow?
   Remodeling or new construction plans
    must be approved by authority having
    jurisdiction (AHJ) prior to starting work

    – State Fire Marshal’s Office

          Fire Alarm Systems
   Fire Alarm System Will Provide
    Three Types of Signals
    – Alarm
                                                    Alarm
    – Trouble – indicates a fault in a
      monitoring circuit or component of the
      fire alarm system
        Bad smoke detector
        Ground fault                              Trouble
    – Supervisory – indicates a problem with
      other fire protection systems being
      monitored by the fire alarm system
        Water valve to sprinkler system closed
                                                  Supervisory
        Clean agent system problem                     Slide 11

        Supervision




                          Slide 12
    Common Fire Detection

       Rate-of-Rise




                            Slide 13
       Manual Pull Stations
   Manual pull devices will be
    located on the wall

   Activated by pulling on a
    handle

   Sends signal to building’s
    fire alarm system which
    places the building into
    alarm                         Slide 14
     Notification Appliances
   Audible alarms (How loud is loud
    enough?)

    – Public – SPL must be 5 dB above any
      ambient noise that lasts 60 sec. or
      more, or 15 dB above the 24-hr
      average, whichever is greater

    – Sleeping quarters – Minimum of 75
      dBA
                                            Slide 15
     Notification Appliances
   Voice Communication

    – Better to have a larger number of
      lower SPL units vs. a few very
      loud units

    – Intelligibility can be a problem

                          As temperature rises
                          the bulb will shatter


 Only  the sprinkler heads heated by the fire activate
 Fire sprinklers spray 18 gallons of water per minute

                             Slide 25
           Dry-Pipe System
 System   contains air under pressure
   – Compressor on system keeps pressure up
 Sprinkler heads hold the pressure
 A dry-pipe valve holds back the water supply
 Valve opens when pressure falls below a
  predetermined level
 Sprinkler head activation – pressure drop – valve
  opens – water sent to all heads – water discharged
  from activated sprinkler head(s)

* Recommended for areas that could experience freezing

  valve to open and water fills the system
 Water not discharged until fire has generated
  sufficient heat to activate a sprinkler head

 – Is a sprinkler system required?
 – Is a fire alarm system required?
 – Exiting and egress?
 – Emergency power required?
 – Is a smoke control system required?
 – Is a standpipe system required?

Codes  drive facility fire and life safety
 requirements
Know what codes apply to your
 operation
All codes are MINIMUM requirements
Who is your AHJ?
