Chip Shop
« on: May 13, 2009, 09:03:28 AM »
I've been asked to advise on additional protection for a chip shop/hot food outlet within one of our buildings; it would be using an existing shop premises which was formerly an insurance sales office.  It's on the ground floor and opens onto what is effectively a small shopping mall with MoE at both ends, the existing shop front glazing etc. is 1/2hr FR.  Is there specific guidance for this type of outlet? My initial inclination is to ask for a 1hr FR shutter linked to the fire alarm system (which is L1) and an 'Ansul' system for the fryers.  Thanks for any help  :)

Be careful here in regards to roller shutters linked to fire alarm system. If the fire alarm sounds and closes the shutter is there an alternative means of escape from the unit within the requisite travel distance.
Ansul system good.
Is the door 1/2 hr fr?

Maybe gas shut off to the fryers linked to the fire alarm system?

Agree with ansul.

The fire shutter linked to the fire alarm should not close initially on activation but power down to within 2000mm of the floor to create a smoke Reservoir and allow means of escape from the unit then after 3 minutes power down to the floor to maintain FR to the mall (if required)

Only I would think if there was an alternative means of escape from the unit.

Another way to look at this, if 1/2 hour was reasonable when it was an office then could it be suitable for a chip shop too?

I would say yes, as the glazing will last 1/2 hour 'of the test' regardless of what is causing the fire behind it.

Izan, forming a smoke reservoir in something as small as a chip shop would be next to useless as the volume of smoke from a reasonable size fire will overwhelm it quite rapidly, also the chances are that the actual shop front above a standard 2m high door will create this small reservoir anyway.

But, if a 1hr shutter is definitely required, then have it descend on a fusible link and not smoke.

An absolute for a fixed Wet Chemical or Water Mist System, plus a wet chemical portable.

(by the way just like not all vacuums are Hoovers, not all Wet Chemical fixed systems are Ansul, don't forget Amerex KP or for less mess & downtime water fog systems such as Ultra-Fog)

Where will the ductwork go? - as if a fire enters the ducts then this can be a major hazard.

A written management regime for the intervals of filter cleaning/replacement & ductwork deep cleaning should be requested alongside the FRA for the unit

Thanks to all for your advice, the other commercial premises in the area have a 4 minute delay on their shutters but they all have an alternative exit.  The installation of ducting will be so involved that I'm hoping it'll deter the new tenant from moving in at all! The building has a gas shut off arrangement already and we require weekly cleaning of filters plus deep cleaning of ducts at the appropriate intervals.  I like your thinking Civvy, but there's an element of meeting people's expectations in this case, office politics  ::)
