The Control of Substances Hazardous to Health (COSHH) Regulations 2002 are a set of rules that govern the way businesses use dangerous materials so they do not cause harm to people, premises and places.

Having the correct equipment for chemical storage and handling is an important part of working within COSHH rules. Additionally, particular care should be given to those that are stored in drums and cylinders, with specialised apparatus being used wherever possible.

A major part of COSHH compliancy is incident planning and knowing what to do in an emergency. Ensuring your business has sufficient spill control supplies for quick and efficient clean up should an accident occur is vital. By assessing hazards and forming a cohesive COSHH policy you can minimise the risk of a serious incident in your workplace.

Buying Guide - What is COSHH?

COSHH Regulations Explained

Hazardous substances can take many forms and are common in just about every workplace. As the name implies The Control of Substances Hazardous to Health (COSHH) Regulations 2002 concern themselves with the measures you need to take to make working with such substances safe.

It would be easy to imagine that only large industrial sites or those with lots of staff would need to be concerned with COSHH regulations, but this is not the case. Businesses of any size and type from florists and funeral homes to repair centres and restaurants are required by law to make COSHH provisions.

When deciding how COSHH regulations apply to you and your workplace you should consider whether any of the following are present while you work:

  • Chemicals or products that contain them

  • Mists

  • Fumes and vapours

  • Dust

  • Gases

  • Biological agents

All of these can be classed as substances that require some form of control in order to work with them safely. Simple everyday items such as cleaning products, glue or paint will therefore need to be considered as part of your COSHH provision. However this list is not exhaustive - to assess whether a product has COSHH implications for your business you should check any information that was provided with it, ask your supplier or look online.

COSHH Essentials

Good COSHH procedures consist of several important steps, including those outlined below. By working through these and continuously monitoring their effectiveness you can efficiently control any risk.

COSHH Assessment

Once you’ve ascertained whether a substance will require control measures you will need to look in further detail at how and why it is present and the possible ways this could affect workers’ safety. Consider also the tasks that are to be performed around the substance to determine the scale of the threat. Handling small amounts of chemicals in a can may well be assessed as having a low risk, however the cleaning or disposal of drums that contained the same substance might be decided to carry a greater risk of exposure and require tougher control measures.

Make a written record of your COSHH assessment and any measures you are taking to reduce risk. This is a legal requirement if you have five or more employees and good practice in any event.

Hazard Control

Use the findings from your risk assessment to decide which control measures each task and substance will require. You might find that ultimately you can prevent the risk by eliminating the use of harmful materials entirely. Where this is not possible you should be seeking to adequately control the risk instead. Think about your operating processes and what equipment you might be able to use to make them safer. Specific items for carrying and storing containers such as drums or cylinders are a must. For smaller amounts of chemicals or flammable materials, spill-containing cupboards are extremely useful for safe storage. Having adequate waste disposal systems can prevent cross-contamination and industrial strength cleaning equipment such as vacuum cleaners will keep potentially harmful dust from gathering. Consider enclosing work areas and minimising the number of workers who come into contact with dangerous substances. Personal protective equipment (PPE) items such as gloves, facemasks and protective overalls are regularly used as part of COSHH provisions; however they should be regarded as a last resort and used only where the risk from a substance can’t be mitigated using alternative materials or working practices.

Monitoring & Surveillance

Once you have implemented any procedural changes and suitable equipment is in place it is extremely important to make regular checks to ensure processes are working as they should. These should be carried out by a competent person. Look for any uncontrolled contaminants and ensure workers have access to COSHH training in order to follow procedures correctly. For certain risk types it may be necessary to carry out health checks on relevant personnel from time to time.

Incident Planning

When working with dangerous materials it’s important to be ready for anything. Use your risk assessment and information on the substances in question in combination with other factors such as your location to come up with an emergency response plan. Make sure equipment for cleaning spills is available as well as relevant first aid supplies, including any specialist items specific to the risk. Have technical information on substances readily accessible so it can be passed to emergency services quickly. Make sure alarms and communication systems are in place so that staff are alerted of any problems immediately and have adequate signage to aid in evacuation. Substances and storage furniture must be labelled using the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Your incident plans should be checked regularly for suitability and adapted if required.

How can I find out more about COSHH symbols and a particular substance?

If a substance you use is marked with one of the universally recognised GHS hazard symbols your supplier should also provide a safety data sheet which includes information regarding the specific risk and safe usage and storage. It will also advise on any emergency measures that are appropriate.

I run a very small business, how can I be sure it’s COSHH compliant?

You may well find that even if you do work with hazardous materials your risk is deemed to be very low; however it is important to carry out an assessment to be sure. Although smaller businesses are not required to record this process it is a good idea to do so anyway.
