Megazyme – Firevault – Fire Rated Store Case Study

The clients requirements

Mr. Niall McCormack of Megazyme contacted Chemstore in relation to our Firevault Fire Rated Store range and outlined a project for two 4 Pallet Firevaults. The project required a 1Hr Fire Rated construction and required sliding doors due to the tight space on site. There was a tight offloading area which was taken into account during our full site inspection. The 2 stores also needed to have the same floor space as 2 previous stores.

Client Testimonial

“We purchased two Firevaults from Chemstore. From the beginning, the Chemstore team were easy to deal with and very professional. Every detail was explained from the design phase to the installation phase. Both Fire Rated Stores are built to a high standard and are suitable for our requirements. I highly recommend Chemstore and look forward to dealing with them into the future”.

Our solution


Storage: 4 pallets, 16 x 200L drums or 4 X 1,000L IBC’s, stored on 1 level.

Overall dimensions: (L) 6,000mm x (W) 2,030mm x (H) 2,650mm

Construction: Robust all welded 100 x 50mm steel box section frame.

Sumps: Non-combustible, corrosion resistant coated steel sumps fitted under floor level.

Shelving: Shelving constructed from fully galvanised grid decking.

Access: Twin heavy-duty sliding doors, fully padlockable.

Lifting: Unit is fitted with forklift channels and roof-fixed crane lift points to allow for easy unloading and relocation.

Ventilation: 4 no. intumescent ventilation Pyrogrilles fitted as standard at high and low level to ensure good ventilation throughout the store.  When tested to BS 476 part 22 the panels exhibit a 1 hour fire-rating.

Sealing: Full door, intumescent, elastomeric, neoprene-based seals are installed where possible, to protect the Firevault and its contents from the spread of flame and heat. All seals have self-extinguishing properties in fire and are not affected by toxic fumes, dust, or weather conditions. A polypropylene brush with a central blade is also incorporated to act as weather, draught and smoke excluder. Tested to BS476/31.1


Wall Cladding: The 100mm thick Fire-rated panels are fabricated from high quality resin bonded Conrock slab and are securely fixed using the tongue and groove method, for added stability, to the robust welded steel box framework. The internal face is finished with polyester coated internal zinc steel panels. When tested in accordance with BS 476 part 22 1987 the panels exhibit the following results:

Resistance to the passage of flames 110 mins.

Insulation on temperature 80 mins.

Stability >110 mins

There is, therefore fire resistance to the wall construction of 80 mins.

External colour: Choice, standard Goosewing Grey.

Internal colour: Choice, standard White.


Roof Cladding: In accordance with Health & Safety Guidance Notes HS(G)51, which states that: –

“External storage buildings, whether or not they are fire-     resisting structures, should have a light-weight roof to act as explosion relief.”

The profiled, single skin roof cladding is therefore designed to be of a notably lighter construction than that of the wall and door panels.

Finish:  Framework: All steel coated with high build Acrylic paint finish system to ISO 3233:1998.

Choice of colours. Standard: Red RAL 3020.

External:Long life, maintenance-free Plastisol (PVC)

finish on wall panels.

Choice of colours.

Standard colour: Goosewing Grey.

Internal: White chemical resistant Stelvetite (PVC) finish on internal walls.


Signage: Clear and bold “Firevault”, “Flammable, No Smoking, No Naked Light” and “Keep Door Closed When Not In Use” signs fitted as standard, to BS499. Specific signage available on request.
