COSHH Stores – Hazardous Substance Storage

Control Of Substances Hazardous To Health

Perfect For Chemical Storage, COSHH Storage And Bunded Storage

Secure Storage +

Bunded COSHH Stores are “Sub-Floor” Bunded Chemical Store which can provide safe and secure storage of hazardous substances or flammable materials which must be stored in compliance with COSHH regulations being that all these plus any pesticides or fertilisers are stored safely to protect human, animal and environmental welfare, Perfect for Agricultural Chemical Stores.

Our Bunded COSHH Stores are converted from ISO Shipping Containers similar to our Bunded Chemical Stores but have a sub-floor bund with a raised mesh floor. This avoids the potential trip hazard of an additional step and allows any hazardous or flammable materials drain into the sump below the pedestrianised area protecting users of the container from any harm from any hazardous substances stored within the chemical store. Our Bunded COSHH Stores are lockable for adherence to security policies.

What Is COSHH ?

COSHH is the law that requires employers to control substances that are hazardous to health. You can prevent or reduce workers exposure to hazardous substances and minimise risk by:

  • Finding Out What The Health Hazards Are
  • Providing Control Measures To Reduce Harm To Health
  • Adhering To Strict Labelling Protocols for All Hazardous Substances
  • Deciding How To Prevent Harm To Health
  • Using Them By All Employees And Others
  • Keeping All Contact Measures In Good Working Order
  • Providing Information, Instruction And Training For Employees And Others
  • Providing Monitoring & Health Surveillance In Appropriate Cases
  • Planning For Emergencies

Most businesses use substances, or products that are mixtures of substances. Some processes create substances. These could cause harm to employees, contractors and other people.

Substances are sometimes easily recognised as harmful, common substances such as paint, bleach or dust from natural materials may also be harmful.

What Are COSHH Substances ?

COSHH covers substances that are hazardous to health include

  • Hazardous Chemicals
  • Hazardous Materials
  • Products Containing Chemicals
  • Fumes
  • Dust
  • Vapours
  • Flammable Substances & Flammable Liquids
  • Mists
  • Nanotechnology
  • Gases & Asphyxiating Gases
  • Biological Agents-Germs
  • Germs That Cause Diseases Such As Leptospirosis & Germs Used In Labs

Hazardous substances refer to individual chemical substances as well as preparations that include a mixture of one or more such as paint, solvents, cleaning materials, pesticides and gas cylinders.

However, these regulations do not cover lead, asbestos and radioactive substances, with these being subject to their own specific regulations. As well as using chemicals, some manufacturing processes may also create substances which could be harmful to employees, contractors and other people.

What Is Classed As Hazardous ?

A hazardous substance or dangerous substance is one which features at least one inherent hazardous property such as flammability, explosiveness, corrosiveness or toxicity.

This may mean that it has the potential to result in long-term damage to the health of employees, including injury to lungs, skin, nose, mouth, genes, eyes, the central nervous system and internal organs. There are three main routes on how a person can be affected by a harmful substance such as, inhaling, absorption of an irritant through the skin and ingestion.

Alternatively, the substance may pose a risk of combustion or explosion or due to its ability to oxidise. It’s important to note that although there is a wide range of substances that have the potential to cause harm, when used properly and in line with the appropriate protocol, they rarely do.

How Are Businesses Responsible For COSHH ?

In order to ensure compliance, employers must assess risks related to COSHH substances used within the workplace and provide safe storage in line with regulations.

They will then need to determine measures to prevent or adequately control exposure. Plus, they should be aware of the hierarchy of control measures that must be followed in relation to the risk associated with a specific substance.

In summary, chemical storage should be in accordance with the manufacturers instructions and safety data sheets. The storage area should include sufficient space, be organised and tidy, contain good lighting and be well ventilated. It should also have a floor that is resistant to chemical damage and is easy to clean and maintain.

Ultimately, the organisation or employer is responsible for the implementation of COSHH, with obligations including:


To identify potential hazards, businesses must complete regular COSHH and risk assessments. The assessment concentrates on the hazards and risks posed by the use or production of specific substances which include the steps:

  1. Identify Potential Hazards
  2. Identify Who Could Be Harmed And How
  3. An Evaluation Of The Risks
  4. Establish Precautionary Measures including Signage 
  5. Record Findings
  6. Implement Changes
  7. Review And Evaluate

Depending on the type of COSHH substance and it’s particular properties, the assessment should include consideration of work circumstances including safe handling, storage, transportation of hazardous substances and appropriate waste removal.


COSHH requirements mean that employers have a responsibility to control any substances that may be hazardous to health. If it is not possible to completely prevent exposure by using a different substance, measures could include checking for damage or leaks regularly , ensuring that damaged containers, storage lockers or storage cupboards are replaced immediately and making sure that any spills are cleaned up immediately.

Waste should also be segregated from other substances and labelled appropriately. Furthermore, it is also essential for businesses to be aware of the applicable Workplace Exposure Limits (WEL’s) for the substances used. This refers to the limits of legal maximum exposure and is dependant upon the type of hazardous substances used for the work activity.


Businesses are legally obligated to monitor and maintain the control measures that they have put in place as part of the COSHH assessment. This may include health surveillance, which refers to a regular system of ongoing health checks.

This approach is effective at ensuring any ill health is discovered early, at evaluating risk, and it’s effective at reinforcing training and education. Moreover, health surveillance also provides a platform for employees to raise concerns about the use of hazardous substance in the workplace. Depending on the type of business, this may or may not be a legal requirement.


Businesses have a duty to protect workers from harm and to reduce the risks associated with the substances required for the work activity.

An example of a protective measure is the use of PPE (Personal Protective Equipment). Although this can add an extra layer of safety, it should be considered the last line of defence. The use of some hazardous substances may also require employees to wear Respiratory Protective Equipment.


It is imperative for companies to ensure that all employees understand the necessary precautions related to the use, storage and transportation of COSHH substances.

As well as being aware of which substances are hazardous, it is also important for workers to know why they are hazardous and what damage they could cause. COSHH training can go some way to ensure that control measures are maintained, but it needs to be regularly updated to ensure that it’s in line with current guidelines.


Businesses are also required to report and record accidents, spillage and breakages in line with the Reporting of Injuries Diseases and Dangerous Occurrence Regulations (2015) Most incidents should be reported online, but there is a telephone service for reporting fatal and specified injuries only.
