Chemical & Hazardous Substance Storage
HERMEQ supplies COSHH stores for the secure storage of hazardous substances on construction sites and at events, as well as in factories and warehouses. The range covers lockable steel boxes and chests, steel and polyethylene COSHH cabinets, ventilated mesh cages and walk-in modular stores, each designed for storage in line with the Control of Substances Hazardous to Health (COSHH) Regulations. Together they contain chemicals, fuels, flammables and corrosive materials, keep them away from untrained hands and stop leaks reaching the ground. The steel boxes, chests, cabinets and cages are made in the UK, and much of the range is held in permanent UK stock with next day delivery.

COSHH cabinets, chests, cages and walk-in stores
The range is best chosen by the containers it has to hold. Tins, aerosols and small bottles go in boxes, chests and shelved cabinets. Jerry cans, drums and IBCs go in steel cabinets, cages and bunded stores. A compound's full stock of hazardous substances goes in a walk-in store.
Chemical storage boxes and security chests
Low, lockable steel boxes, which buyers also call a COSHH bin, COSHH box or COSHH container, hold the paints, adhesives, solvents, aerosols and cleaning chemicals that a gang uses from day to day. The hazardous substances storage box is the compact choice for a single trade or a small site. The chemical storage chest is taller and comes in longer sizes, so larger tins and containers stand upright without being stacked. The Chemstor chemical storage container is built from structural grade steel with a heavy sump, and its largest size has shelves that keep small containers in order and in view.
Steel COSHH cabinets for drums and IBCs
Lockable steel COSHH cabinets take the larger containers: jerry cans of fuel, oil drums and IBCs. The steel COSHH storage cabinet comes in two sump capacities. It suits a site that keeps a handful of drums and cans of fuel and oil. The heavy duty COSHH cabinet is the choice for large sites that store several 205-litre drums or IBCs, and it has wide doors for loading full containers.
Polyethylene COSHH cabinets
The polyethylene COSHH cabinet is rotationally moulded and made in several formats. Shelved, lockable versions keep bottles and containers of cleaning chemicals, acids and treatments organised in workshops, welfare units and facilities stores. A drum version holds a single 205-litre drum upright, for a site or plant room that dispenses from one drum.
COSHH cages
A COSHH cage has galvanised steel mesh sides over a fully welded sump. It is the format for oil, fuel and other liquids kept outdoors in a compound. The open mesh lets vapours disperse and leaves the contents visible for a stock check.
Walk-in modular COSHH stores
When the stock of fuels, oils and chemicals outgrows a row of cabinets, a modular COSHH store gives the compound one walk-in store for all of it. It comes in several footprints at a common height, so it can be sized to the stock held on a long project or at a permanent depot.
Bunded chemical stores
The bunded chemical store is sized by the number of containers it holds. It is the chemical store for depots, yards and facilities that keep substances in quantity, where containers of the same class are stored together in number and need one bunded floor beneath them.

Bunded COSHH stores and sump capacity
A bund is the liquid-tight base that catches a leak before it reaches the ground or a drain, and it runs through the range. The steel cabinets and the COSHH cage stand on integral sumps, the polyethylene cabinets carry their own bund, the Chemstor container has a heavy wall sump, and the bunded chemical store is built around one. The sump is sized to the largest container stored, so a store holding 205-litre drums needs a sump that can take the whole contents of one drum, with more capacity where several are kept together.
Removable steel grid floors in the heavy duty cabinet and the COSHH cage hold containers above the sump. A leaking drum therefore does not stand in its own spill, and the grid lifts out so the sump can be emptied and cleaned. Drums and IBCs kept on an open floor or in a workshop go on a COSHH sump pallet. This is a PVC bund with hazard signage on its sides, which marks the load as dangerous goods. The containers themselves, from steel drums to IBC tanks, are in the range of drums and IBCs.
COSHH storage on construction sites
On a construction site, the choice turns on three things: the substance stored, the risk of theft and how often the store has to move.
Steel or polyethylene
Steel is the material for fuel, oil and flammable liquids. The steel COSHH cabinets are fire resistant, with the standard cabinet rated for up to 30 minutes, and their powder coated finish stands up to weather on an open site. Polyethylene is chosen for acids, alkalis and other corrosives, because rotationally moulded polyethylene is compatible with a broad range of chemicals and does not rust. Lithium-ion tool batteries are stored apart from both, in a lithium-ion battery storage cabinet built from sheet steel with an acid-resistant epoxy coating.
Security for fuel and oil on open sites
Fuel and oil are a target for theft from an open compound. The steel cabinets have heavy duty doors and 5 lever deadlocks, and the heavy duty cabinet has two deadlocks. The boxes, chests and Chemstor containers lock shut on steel bodies. Hand tools and plant go in a separate site storage vault, so the COSHH store is opened only for the substances in it.
Moving stores between sites
Several formats are built to move with the job. The heavy duty cabinet sits on forklift skids, and the COSHH cage and sump pallet have forklift pockets, so each can be lifted onto a lorry and set down at the next compound. The cage also collapses and stacks, which saves space on the return load and in the yard between contracts. The modular store is supplied flat packed and is quick to assemble, so it travels on an ordinary delivery and goes up where it is needed.
