The Essential Guide to Storing Hazardous Materials Safely

In today’s industrial landscape, the proper storage of hazardous substances is a critical aspect of workplace safety and environmental protection. For businesses in the UK, understanding how to store hazardous materials safely is not just a matter of best practice – it’s a legal requirement.

This article will explore the essential aspects of hazardous substance storage, providing you with the knowledge to ensure your workplace remains compliant and safe.

Why is proper storage of hazardous substances crucial?

The storage of hazardous substances is a key component of workplace safety. Improper storage can lead to accidents, injuries, and environmental damage. Moreover, it can result in severe legal consequences and financial penalties. The Control of Substances Hazardous to Health Regulations 2002 (COSHH) [1] mandates that employers must prevent or reduce workers’ exposure to hazardous substances. This includes ensuring that these materials are stored safely and securely.

What are hazardous substances?

Hazardous substances are materials that have the potential to cause harm to human health or the environment. These can include chemicals, biological agents, and even certain types of dust. In the workplace, common hazardous substances might include cleaning products, solvents, paints, and industrial chemicals. It’s crucial to remember that even seemingly innocuous materials can be hazardous if not handled and stored correctly.

How do you identify hazardous substances?

Identifying hazardous substances is the first step in ensuring their safe storage. Most hazardous materials will come with a safety data sheet (SDS) that provides detailed information about the substance’s properties, potential hazards, and safe handling procedures. 

Additionally, hazardous substances are typically labelled with standardised hazard symbols that indicate specific risks such as flammability, toxicity, or corrosiveness.

What are the key principles of hazardous substance storage?

When it comes to storing hazardous substances, several key principles should be followed:

Segregation

Incompatible substances must be stored separately to prevent dangerous reactions if accidental mixing occurs. For example, flammable liquids should never be stored near oxidising agents.

Containment

Use appropriate storage containers that are resistant to the substances they contain. Ensure that containers are properly sealed to prevent leaks or spills.

Ventilation

Adequate ventilation is crucial, especially for substances that emit harmful vapours. This helps to minimise the risk of exposure and reduces the potential for the build-up of hazardous atmospheres.

Temperature control

Some substances may require specific temperature conditions for safe storage. Always refer to the manufacturer’s guidelines and the safety data sheet for information on optimal storage temperatures.

Security

Hazardous substances should be stored in secure areas with restricted access to prevent unauthorised handling or theft.

Labelling

All storage areas and containers should be clearly labelled with the appropriate hazard symbols and substance information.

How should you store flammable substances?

Flammable substances require special attention due to their potential to ignite and cause fires. Here are some key considerations for storing flammable materials:

  • Use dedicated flammable storage cabinets that meet safety standards.
  • Ensure electrical equipment in the storage area is explosion-proof.
  • Implement a no-smoking policy in and around storage areas.
  • Keep flammable substances away from sources of heat or ignition.
  • Use only non-sparking tools when handling flammable materials.

What about corrosive substances?

Corrosive substances can cause severe damage to skin, eyes, and other materials. When storing corrosive substances:

  • Use corrosion-resistant containers and storage cabinets.
  • Provide spill containment measures such as bunded areas or drip trays.
  • Store acids and bases separately to prevent dangerous reactions if mixed.
  • Ensure eye wash stations and safety showers are readily available nearby.

How do you manage the risks associated with hazardous substance storage?

Risk management is a crucial aspect of hazardous substance storage. This involves:

Conducting regular risk assessments

Risk assessments should be carried out systematically and regularly. This process involves identifying all hazardous substances present in the workplace, evaluating the potential risks they pose, and assessing the effectiveness of existing control measures. 

Providing comprehensive training to employees

Training should cover topics such as the types of hazardous substances present and their risks, how to read and interpret safety data sheets and labels, proper handling and storage procedures, and the use and maintenance of control measures, including PPE. 

Regularly inspecting storage areas and containers

Implement a routine inspection program that includes checking containers for leaks, corrosion, or damage, ensuring labels are legible and up-to-date, verifying that incompatible substances are properly segregated, and confirming that storage areas are clean, well-ventilated, and at appropriate temperatures.

Developing and maintaining emergency response procedures

 Emergency procedures should include clear instructions for immediate actions in case of a spill or release, evacuation plans and assembly points, contact information for emergency services and internal response teams, and locations of emergency equipment (e.g., spill kits, fire extinguishers, safety showers). 

What role does COSHH play in hazardous substance storage?

The Control of Substances Hazardous to Health Regulations 2002 (COSHH) is the primary legislation governing the use and storage of hazardous substances in UK workplaces. COSHH requires employers to:

  • Assess the risks associated with hazardous substances in the workplace.
  • Implement appropriate control measures to minimise these risks.
  • Provide information, instruction, and training to employees.
  • Monitor exposure and carry out health surveillance where necessary.
  • Plan for emergencies.

Compliance with COSHH is not just a legal requirement—it’s essential for protecting the health and safety of your workforce and the environment.
