Why are Safety Data Sheets Important?

Safety data sheets are very important to your organisation and chemical safety approach. First and foremost, they allow you to understand more about the hazardous chemical products you have on site and how to properly use them, mitigate risks related to them, and more. This information can help you develop chemical procedures, training, risk assessments, etc. Safety data sheets are also critical for you to maintain compliance within your region and industry.  

If you are located within Europe, you need safety data sheets to be compliant with Restriction, Evaluation, Authorization and Restriction of Chemicals (REACH), and Classification, Labelling and Packaging (CLP) regulations. If you are located in the United States or Canada you should follow the requirements outlined by the Occupational Safety and Health Association (OSHA) and Workplace Hazardous Materials Information System (WHMIS) respectively.

6 Sections to Focus on Within Your SDS

As previously mentioned, all of this information can be overwhelming and time consuming to read. We want to make sure you’re optimising your time and creating a safe working environment for your employees. That’s why we’ve narrowed it down to 6 sections you should focus on when going through your safety data sheets.  

1. Section 2- Hazard(s) Identification

Section 2 covers the hazards of the chemical product and how it could potentially harm your employees. Pictograms outlined by Classification, Labelling and Packaging regulations (CLP) if you are located in Europe, OSHA if you are in the United States, and WHMIS in you are in Canada, are usually found in this section.

Use this section to become familiar with the hazards this chemical product could pose, so you can come up with safety procedures, policies, and training to help mitigate any risks.  

2. Section 4- First Aid Measures


3. Section 6- Accidental Release Measures

Section 6 outlines what must be done if there is a chemical leak or spill on site. Read this section to learn more about how to properly clean it up, the personal protective equipment (PPE) employees need to wear when cleaning up, and what to do to prevent this from reoccurring.  

Make sure you resource the proper tools and PPE needed for employees to deal with such a situation based on the recommendations outlined in the SDS, and develop employee training procedures and policies, so they are prepared if such an event occurs. Don’t forget to communicate these accidental release measures and any documents you develop with your teams.  

4. Section 7 and Section 10- Handling and Storage / Stability and Reactivity



5. Section 8 - Exposure Controls and Personal Protection
