Frequently Asked Questions
What is a Safety Data Sheet (SDS)?
A Safety Data Sheet is a standardised document that provides detailed information about a chemical product’s hazards, safe handling procedures, storage requirements, and emergency measures. Under UK REACH and CLP regulations, suppliers must provide an SDS for hazardous substances to ensure workers can handle them safely.
How often should Safety Data Sheets be updated?
Safety Data Sheets should be reviewed and updated whenever new hazard information becomes available, when regulations change, or when the product formulation changes. Suppliers must update SDSs promptly and provide revised versions to customers. As a best practice, review your SDS library at least annually to ensure all documents are current.
Who is responsible for maintaining Safety Data Sheets?
Employers are legally responsible for obtaining and maintaining current SDSs for all hazardous substances used in their workplace. While suppliers must provide SDSs, employers must ensure they’re accessible to workers, kept up-to-date, and used to inform COSHH risk assessments and safe working procedures.
What are the 16 sections of a Safety Data Sheet?
The 16 mandatory SDS sections are: (1) Identification, (2) Hazard identification, (3) Composition/ingredients, (4) First-aid measures, (5) Fire-fighting measures, (6) Accidental release measures, (7) Handling and storage, (8) Exposure controls/PPE, (9) Physical properties, (10) Stability and reactivity, (11) Toxicological information, (12) Ecological information, (13) Disposal, (14) Transport, (15) Regulatory information, and (16) Other information.
How do I find the right Safety Data Sheet for a product?
Search using the exact product name as shown on the container, the manufacturer name, and optionally the CAS number for precise identification. Sevron’s SDS search tool lets you search millions of SDSs by product name, manufacturer, or CAS number, with multi-language options and instant PDF access.
What’s the difference between an SDS and an MSDS?
MSDS (Material Safety Data Sheet) was the older format with varying structures across countries. SDS (Safety Data Sheet) is the globally harmonised format introduced under GHS with a standardised 16-section structure. Since June 2015, all safety data sheets in the EU/UK must follow the SDS format. The terms are often used interchangeably, but SDS is the current standard.
How should Safety Data Sheets be stored and made accessible?
SDSs must be readily accessible to all workers who handle hazardous substances. Store them in a central location—whether physical folders or digital systems—where workers can quickly access them. Digital SDS management systems like Sevron allow instant search and retrieval, automatic updates, and access from any device.
Can I use a Safety Data Sheet from another country?
SDSs must comply with the regulations of the country where the substance is used. UK/EU SDSs follow CLP regulation formatting, which may differ from US OSHA requirements. Always use region-appropriate SDSs and check that the language, hazard classifications, and regulatory information match UK requirements.
