Understanding Safety Data Sheets: A Guide for Safe Chemical Use

When it comes to using chemical products like detergents and disinfectants, safety is paramount. That’s where Safety Data Sheets (SDS) come into play. An SDS is a document that provides detailed information about a chemical product’s properties, potential hazards, safety precautions, and emergency procedures. Understanding how to read and interpret an SDS is crucial for anyone using chemical products in the workplace. Let’s break down the key components of an SDS and address some common misconceptions to ensure you’re using chemical products safely and effectively.

What is a Safety Data Sheet?

A Safety Data Sheet is a comprehensive document that outlines essential information about chemical products. Manufacturers are required to provide an SDS for each chemical product, ensuring that users are informed about its properties, hazards, and safe usage guidelines. The sheet is divided into sections, each detailing specific aspects of the chemical, such as its composition, first-aid measures, handling and storage recommendations, and disposal guidelines.

Key Sections of an SDS

  1. Identification: This section provides the product’s name, manufacturer details, and emergency contact numbers. It’s your go-to for knowing exactly what you’re using and whom to call in an emergency.
  2. Hazard Identification: Here, you’ll find the product’s classification, warning labels, and potential health and environmental hazards. This section helps you understand the risks associated with the product.
  3. Composition/Information on Ingredients: This part lists the chemicals in the product, especially those that contribute to its hazards. Knowing what’s in your product can help you understand the risks and necessary precautions. Ingredients are listed in order of concentration from highest to lowest.
  4. First-Aid Measures: It outlines the steps to take in case of accidental exposure or ingestion. This information is crucial in emergency situations.
  5. Fire-Fighting Measures: This section provides guidance on extinguishing fires caused by the chemical, including suitable extinguishing methods and protective gear for firefighters.
  6. Accidental Release Measures: It details the procedures to follow if the product is spilled or released, including clean-up practices and environmental precautions.
  7. Handling and Storage: Here, you’ll learn how to safely handle and store the product to prevent accidents and maintain its efficacy.
  8. Exposure Controls/Personal Protection: This section advises on how to limit exposure to the chemical and the types of protective equipment needed. Check the finer details, for example nitrile gloves will often be subject to a European standard which ensures they are resistant to chemicals, not all nitrile gloves are appropriate.
  9. Physical and Chemical Properties: This provides information on the product’s appearance, odour, boiling point, and other physical characteristics.
  10. Stability and Reactivity: It informs about the product’s chemical stability and potential hazardous reactions.
  11. Toxicological Information: This section details the health effects of exposure to the chemical, including toxicological data and likely routes of exposure.
  12. Ecological Information: Here, the potential environmental impacts of the chemical are described.
  13. Disposal Considerations: It provides guidance on the proper disposal of the product and its container.
  14. Transport Information: This section includes information on how the product should be transported safely.
  15. Regulatory Information: It outlines the specific regulations that apply to the product.
  16. Other Information: This may include the date of the last SDS revision and additional notes.

Common Mistakes and Misconceptions

Overlooking the SDS: Always consult the SDS before using a chemical product, even if you’ve used it before. Safety guidelines and product formulations can change.

Ignoring Personal Protective Equipment (PPE) Recommendations: The SDS specifies the necessary PPE. Using the right protective gear can prevent accidents and exposure.

Misunderstanding Hazard Symbols: Familiarise yourself with hazard symbols and what they mean. They provide quick, visual cues about the risks associated with a product.

Neglecting First-Aid Measures: Know the first-aid measures beforehand. In an emergency, quick and correct actions can make a significant difference.

Improper Storage: Follow the storage guidelines on the SDS. Incorrect storage can lead to chemical degradation or dangerous reactions.

Assuming All Products Are Similar: Different products, even within the same category or within the same brand, can have varying ingredients and hazards. Always read the SDS for each specific product.

Using Obsolete Documents: Safety Data Sheets should be periodically updated, to ensure that all information is up to date. If you are using safety data sheets which are several years old, it would be advisable to request an updated version from your manufacturer.

Mistaking Ingredient Classifications for Product Classifications: Active ingredients are extremely potent and will likely have much a higher classification than that of the final product, as they are often used at a very low percentage. The product classification in section 2 is the relevant section for users.

The role of SDS in COSHH Risk Assessments

When conducting a Control of Substances Hazardous to Health (COSHH) risk assessment in the UK, an SDS is an invaluable resource. COSHH requires employers to assess the risk of hazardous substances and implement measures to protect employees’ health. An SDS provides the detailed information needed to evaluate the potential hazards associated with a chemical product, helping to form the foundation of a thorough risk assessment.

By examining the SDS, employers can identify the chemical’s properties, its potential health risks, necessary control measures, and appropriate emergency responses. This information is crucial for determining how a substance could harm health and what preventive steps are essential to mitigate those risks. For example, the SDS will indicate if a particular detergent or disinfectant requires specific ventilation requirements or if personal protective equipment (PPE) is necessary during its use.

Incorporating the detailed insights from an SDS, employers can develop a comprehensive COSHH risk assessment and an appropriate training plan for the end-users who will be handling the product.


Safety Data Sheets are your best resource for understanding and safely handling chemical products. Safety data sheets for all Byotrol products are instantly available via the resources section of our website, you can register to access these here. By familiarising yourself with the SDS, especially for commonly used chemicals like detergents and disinfectants, you can protect yourself, others, and the environment from potential hazards Remember, the key to safe chemical use is not just having access to the information but also understanding and applying it correctly. Stay informed and keep yourself and your team safe.
