Preventing thefts through secure storage

Thanks to the time and effort expended by a large number of public spirited residents we have a very active Neighbourhood Watch scheme operating in my area. Trouble is that it appears to do little to deter both the opportunistic and more organised thieves who of late have become more brazen often operating in broad daylight under the noses of residents. With no town gas supply, not surprisingly the most frequent thefts involve stealing home heating oil, but recently there has been a notable rise in thefts of grass mowers and power tools from outbuildings. The thieves probably calculate a ready market exists for their ill-gotten gains as spring approaches.
Insurance will ease the pain but standard policy excesses and loss of no claims bonuses can still leave you hundreds of pounds out of pocket. So what can you do?


Obviously don’t leave out buildings and sheds unlocked or leave windows open. The objective is to put as many security barriers in place as possible to foil the sneak thief and deter the more determined and better equipped criminal. Fit quality locks or padlocks and if possible steel lock covers to prevent access with bolt cutters. You can also buy anti-jemmy door hinges for a few pounds. If you have very expensive equipment like generators and ride on mowers consider extending your home security alarm. These days modern technology means this can be done wirelessly.
If despite your best efforts thieves do gain entry all is not lost (literally). My own mower is chained to the wall using two 15mm eyebolts. As for power tools and other expensive equipment the answer is to lock these away in a secure steel cabinet or tool vault. Depending on the size the Probe Industrial cabinet range provides security for lower value items. For added security you can utilise the heavy duty Oxbox or Tuffbank van boxes made from heavy gauge steel plate that have bolt down features and anti-jemmy lids.
Spending a couple of hundred pounds to safeguard against theft is worthwhile when balanced against the cost and hassle of replacement. The police also advise that thieves will return time and again to properties they consider easy prey so now is the time to be proactive so you don’t become a victim.

Heavy snowfall increases risk of flood and theft

The heavy snow forecast to affect the whole of the UK at some point this weekend is further bad news for those businesses and homeowners at risk of flood. Snow, despite its picturesque effect on the landscape is rain by another name so when it thaws it can only add to the flood risk on already waterlogged ground. Now is the time to take added precautions to safeguard valuable stock and valuables by placing them out of reach of potential flood waters.
This precaution is doubly true if your business uses hazardous chemicals. It is advisable to consider raising hazardous storage cabinets well off the ground on steel stands available to suit most standard COSHH cabinets. Leakage of toxic substances into the environment can have devastating effects and if you are sited in a high flood risk area the environment agency will look to you for proof that sensible precautions were in place should a leak occur.


Valuables can also be stored in the same way in high security storage cabinets placed on stands, or in waterproof security chests and safes depending on the value and quantity of goods to be stored.
Another consequence of the freezing temperature is a significant increase in vehicle thefts. Criminals literally tour the streets looking for vehicles that have been left unattended on driveways with the engine running to defrost the car or van. This presents a golden opportunity for thieves to either steal the vehicle itself or rifle the contents in seconds for any valuables, laptops, tools and equipment.
Commercial vans and lorries can be fitted with lockable heavy duty steel van boxes and cabinets that bolt to the chassis for storage of expensive tools and equipment but that does not prevent theft of the vehicle if the thief has the opportunity. One tip is to use one key to start the engine to defrost and then use the spare key to lock the doors until you are ready to start your journey.
With a little care you can avoid falling victim to the unforeseen risks that the onset of winter weather can present.

Sudoku – safety cupboards

Here is a special version of the popular Sudoku brainteaser that uses letters instead of numbers. The rules are the same, each row, column and 3×3 square box must contain each of the letters in the keyword exactly once.

We have filled in some of the grid to give you a start.

Specialist Storage Solutions for Highly Hazardous Substances

Having explained the basic difference between COSHH and DSEAR compliant hazardous storage cabinets I now return to the issue of more specialist applications where additional precautions are required.
Highly Flammable Liquids (HFL’s) present by far the greatest fire risk in the work environment as they have the potential to self ignite when exposed to low ambient temperatures defined as 32 degrees centigrade or less – air temperatures exceeded in the mini heat wave only a couple of weeks ago.  If your organisation regularly uses HFL’s such as Acetone or Toluene it is not always a sufficient safeguard to store these substances in a standard DSEAR rated hazardous storage cabinet.

From a fire hazard standpoint It is recommended that the maximum quantity that may be stored in standard cabinets and bins is no more than 50 litres for HFL’s with a flashpoint below the maximum ambient temperature of the workroom/working area; and no more than 250 litres for other flammable liquids with a higher flashpoint of up to 55°C (DSEAR ACoP L135, par.40).

You can overcome these restrictions by using specialist fire proof storage cabinets. Typically these are constructed with double skinned insulated walls and doors with fireproof door seals and have in built ventilation systems that exhaust to atmosphere or through air recirculation scrubbers. The Asecos range of fire proof storage cabinets incorporate leading edge design and technology to prevent the temperature within the cabinet from rising above ambient for up to 90 minutes giving ample time for a fire to be brought under control.

They are also used extensively for the storage of biological and environmentally hazardous substances particularly in clean rooms and research and development laboratories where the financial cost of material damage or loss due to fire may be considerable.

The storage of large quantities of toxic and corrosive substances also requires special attention. Under COSHH highly toxic substances such as pesticides and corrosives such as acids and strong alkalis such as caustics should be segregated. To facilitate this hazardous storage cabinets designed specifically for these substances are available. Pesticide/Toxic cabinets have all the attributes of COSHH cabinets with the addition of ventilation grills to prevent the build up of fumes. Acid/Alkali cabinets have an additional corrosion resistant finish. It should be noted that you should not store Acids and Alkalis in the same cabinet as in certain cases they can chemically interact causing an exothermic reaction that risks an explosion or fire. These cabinets are colour coded and carry the applicable hazard identification label.

You will find further information and guidance in our advice pages but if you are unsure or require a solution to your specific storage application please contact us here or call your local HSE office.

Choosing the right Hazardous Storage Cabinet

Selecting the most suitable storage cabinet for hazardous substances can be confusing given the wealth of regulations that businesses are obliged to comply with.

To comply with the Control of Substances Hazardous to Health regulations referred to as COSHH, any substance that presents an environmental or health hazard if inhaled, ingested or through skin contact should be segregated from the active work area in a secure lockable cabinet that complies with the COSHH guidelines.

Generally this means a steel cabinet with spill trays for shelves and lockable doors.

The purpose of the COSHH cabinet is threefold

  1. To prevent accidental contact with the substances
  2. To contain leaking containers or spills from reaching the work area
  3. To prevent spills from causing any environmental damage.

The cabinet should be clearly marked with an HSE compliant Hazard Warning label.

Storing flammable substances is a different matter

Even though you could argue they are hazardous to health and the environment as defined by COSHH their storage is covered by more specific fire safety regulations, primarily DSEAR the Dangerous Substances and Explosive Atmospheres Regulations. There are other legal instruments and requirements for specific activities such as fuel depots.

Flammable substances should be stored separately in a purpose made fire resistant cabinet. Typically paints, solvents and fuels. As with COSHH the cabinet should be equipped with spill trays with a liquid retaining volume of at least twice the volume of the largest storage container in the cabinet.

Flammable storage cabinets are designed with double rebated flush doors and fully welded seams to prevent flames entering the cabinet. The purpose of Flammable Storage Cabinets is to segregate the contents from accidental contact with heat or flame, to provide secure storage, to contain environmentally damaging spills and leaks and to clearly identify their location in a fire emergency.

In the event of a fire the fire resistance of the cabinet is intended to prevent the flammable contents from adding to the fire although the resistance time is no more than 30 minutes depending on the fire intensity and proximity. The cabinets are not insulated and in a fire event with not prevent the internal temperature from rising for more than a few minutes. It is therefore important to use original containers and ensure caps are securely in place.

You should also be aware that there is a distinction between Flammable Liquids and Highly Flammable Liquids or HFL’s. HFL’s have a flash point, at which the liquid or its vapours can auto-ignite, at or below  ambient or room temperature of 32 degrees centigrade. Common laboratory HFL’s are acetone, ethanol and toluene.
