Flamestor Buildings

Specification

Walls

Interlocking precast concrete panels with an applied 'Whitespar' applied aggregate finish externally. Manufactured to CP116 with a steel reinforcement to BS4449, the panel edges are profiled to accept a P.V.C feature strip. Connecting bolts and other fittings are rust resistant.

Roof

A choice of either:

Concrete Roof

Precast concrete units manufactured to CP116, pitched to fall and bolted together with rust resistant fixings. Finished with two layers of hot bonded felt, the top layer being mineral surfaced. A brown plastisol coated steel fascia trims all four sides at eaves level.

Fibre Cement Roof Profiled

Natural coloured, fibre cement sheeting manufactured to BS690, laid to fall and supplied complete with all necessary fixings. A brown plastisol coated steel fascia trims all four sides at eaves level.

Rainwater Guttering

Black vinyl half round guttering with down pipes and all necessary fittings.

Warning Signs

A stove enameled aluminium warning sign is supplied to suit the classification of substance(s) being stored.Doors
A choice of single or double doors in timber. All doors are flush exterior quality, with 1 hour fire resistance to BS476, hung in a softwood frame complete with intumescent strips. All doors are outward opening, supplied painted red gloss and seated on 150mm high precast concrete cill. Doors are fitted with 5 lever mortice deadlock. The clear opening size of single doors is approximately 784mm wide x 1.725m high. Double doors are approximately 1.384m wide x 1.725m high.

Site Preparation

A smooth and level concrete base must be provided by the customer, to the requirements of the local Authority, with dimensions 600mm wider and 600mm longer than the internal dimensions of the Flamestor.

Services

PLANS: Elevation drawings, suitable for submission to the Local Authority, your Fire Officer and Factory Inspector, are available on confirmation of specification.

Construction

Flamestors are constructed nationwide using trained teams.

If assistance is required in deciding the specification for a Flamestor we will be pleased to arrange for a Technical Representative to call by appointment.

Designed and Tested to Meet the Lastest Safety Regulations

Flamestor is designed to satisfy the requirements and recommendations of 1) The Petroleum (Consolidation) Act 1928 and 2) The Highly Flammable Liquids and Liquified Petroleum Gases Regulation 1972 (S.I.917).

The differing requirements of the above regulations are more than adequately catered for by a Flamestor and can broadly divide into two catagories:

1. 1) Storage for Petroleum Mixtures where the specification is normally a precast concrete roof, and
2. 2) Highly Flammable Liquids (H.F.L.) and Liquified Petroleum Gas (L.P.G.) stores which generally require a fibre cement roof.

By offering a modular design with a choice of wall construction, roof design and unit size, a Flamestor is rapidly constructed, at a known cost, with very little on-site disruption.

NOTE: The storage of Petroleum Spirits and Mixtures is controlled by licence and the type of store provided for any material is subject to the consent and approval of the relevant Licensing Authority.

Where a Flamestor is to be used as a high security store and the materials to be stored are non-toxic you may, subject perhaps to the recommendations of your Insurance Company, specify whichever type of store you feel would best suit your purpose.

Roof Construction

• Precast Concrete - generally for external storage of pertoleum spirits and mixtures and internal storage of H.F.L.
• Fibre Cement - generally for external storage of H.F.L., L.P.G. and other substances.

CODE:

1. - 2 hour fire resistance insulated
   precast concrete
2. - 1 hour fire resistance insulated
   precast concrete.
3. - ½ hour fire resistance precast
   concrete.
4. - Non-combustible fibre cement sheets
   to B.S.690

Wall Construction

A choice of three wall specifications is available to satisfy the period of fire resistance required, depending on the type of material stored, the location of the store and other factors.

CODE:

1. - 2 hour fire resistance insulated double precast concrete.
2. - 1 hour fire resistance double precast concrete.
3. - ½ hour fire resistance single precast concrete.

Vents

The walls are provided with 230mm x 230mm cast-in galvanised vents to provide permanent ventilation at high and low level. Copper wire gauze flame arrestors fitted to the internal wall vents can be provided as an optional extra.

Particular requirements for the storage of Liquefied Petroleum Gases (LGP)

Having regard to the advice give in the 'Code of Practice for the keeping of Liquefied Petroleum Gas in cylinders and similar containers' published by the Health and Safety Executive, we supply Flamestors for L.P.G. storage with the following modifications to the standard specificication.

WALLS: The H.S.E. Code of Practice recommends that walls of a purpose-built LPG store have a standard fire resistance of not less than 120 minutes.

DOORS: Standard timber 1 hour fire resisting doors (single or double) over a 150mm high standard cill. Single doors have a clear opening size of 0.784m wide x 1.7258m high (0.9m x 2.0m overall the frame) with Double doors 1.384m wide x 1.725m high (1.5m x 2.0m overall the frame).

VENTILATION: The standard cast in vents are replaced by concrete louvres at both high and low level with a permanently ventilated area amounting to 2½% of the combined area of the walls and roof.
