SDS: what the Safety Data Sheet is and what it is for
— Equipo JP Selecta
To understand it in the chemical, biological and industrial environment, we must define the SDS as the regulatory technical document that sets out in detail the properties, hazards and action protocols of a chemical substance or mixture.
Known interchangeably as a safety data sheet (SDS) or FDS (from the Spanish ficha de datos de seguridad), this informative element is the essential tool for preventing occupational risks, managing emergencies and guaranteeing the responsible handling of hazardous products.
What is the SDS (Safety Data Sheet)?
The Safety Data Sheet (SDS) is a structured document of a legal nature, regulated in Europe by the REACH Regulation (Regulation EC No 1907/2006) and the CLP Regulation (EC No 1272/2008), which contains complete information on the hazardousness of a reagent or chemical product, its physicochemical characteristics, the effects on health and the environment, and the mandatory prevention measures for its industrial and analytical use.
Unlike the container label, which provides a quick, summarised visual alert through pictograms and hazard statements, the SDS offers a broad and exhaustive breakdown aimed at technical staff, occupational risk prevention services and emergency teams.
What is the SDS for?
The central purpose of the safety data sheet is to serve as an operational guide to protect human health, safety on the premises and the preservation of the environment against the possible risks arising from contact with or leakage of chemical substances. Its key uses fall into three areas:
- Protection of workers: it makes it possible to identify the necessary Personal Protective Equipment (PPE) (such as specific gloves, filter masks or safety goggles) and the acceptable occupational exposure limits in the working atmosphere.
- Storage and transport management: it establishes the chemical incompatibilities between products (to avoid violent reactions or explosions) and details the mandatory environmental conditions for storage.
- Effective emergency response: it provides precise instructions for medical and fire services on how to act in the event of ingestion, inhalation, skin contact, accidental spillage or fire.
What information must an SDS include?
To facilitate quick, internationally standardised consultation under the Globally Harmonised System (GHS), the regulations require every SDS to be strictly organised into 16 fixed sections. The following table summarises the mandatory content of each section:
| Section | Official Name | What it includes |
|---|---|---|
| 1 | Identification of the substance or mixture and of the company | Product name, code, recommended uses and contact details of the manufacturer or distributor, including a 24h emergency telephone number. |
| 2 | Hazards identification | Classification of the product under the CLP Regulation, hazard pictograms, signal words, hazard statements (H statements) and precautionary statements (P statements). |
| 3 | Composition / information on ingredients | Identification of the hazardous ingredients that make up the substance or mixture, including CAS and EC numbers, and their concentration percentages. |
| 4 | First-aid measures | Immediate measures following exposure by inhalation, ingestion or eye/skin contact, detailing acute or delayed symptoms. |
| 5 | Firefighting measures | Suitable and unsuitable extinguishing media, specific hazards arising from combustion and protective equipment for firefighters. |
| 6 | Accidental release measures | Personal precautions, environmental protection (containment barriers, isolation) and methods for cleaning up and neutralising the spill. |
| 7 | Handling and storage | Conditions for safe handling, fire prevention and storage requirements (humidity, set-point temperature, ventilation). |
| 8 | Exposure controls / personal protection | Occupational exposure limit values (OELs), required engineering controls (extraction cabinets) and PPE specification. |
| 9 | Physical and chemical properties | Physical state, colour, odour, boiling point, flash point, pH, density, solubility and vapour pressure. |
| 10 | Stability and reactivity | Reactivity of the product, chemical stability under normal conditions, possibility of hazardous reactions and incompatible materials. |
| 11 | Toxicological information | Data on acute toxicity, skin corrosion, mutagenicity, carcinogenicity, reproductive toxicity or effects from repeated doses. |
| 12 | Ecological information | Ecotoxicity (effects on aquatic/terrestrial fauna), persistence, degradability, bioaccumulation potential and mobility in soil. |
| 13 | Disposal considerations | Safe methods for treating chemical waste and contaminated containers in accordance with current waste legislation. |
| 14 | Transport information | Classification and UN number for land (ADR), sea (IMDG) or air (IATA) transport, including packing groups. |
| 15 | Regulatory information | Specific legislative provisions on safety, health and the environment at national or European level (REACH, restrictions). |
| 16 | Other information | Full text of the H and P statements, SDS revision date, explanation of abbreviations and data sources used. |
Regulatory compliance and facilities: Section 7 and section 8 of the SDS usually require strict environmental storage conditions (such as temperature limits or environments free from ignition sources) and continuous ventilation systems.
Having suitable laboratory equipment, such as that which we manufacture at J.P. Selecta, is essential in order to comply with the safety specifications described in the technical sheet of each product.
Who must draw up the SDS?
The legal responsibility for drawing up and supplying the Safety Data Sheet lies with the manufacturer, importer or distributor that markets the chemical substance or mixture.
The supplier must provide the SDS free of charge, in physical or electronic format, in the official language of the member state where the product is marketed. This delivery must take place, at the latest, at the time of the first supply of the substance to a professional or industrial user.
When must an SDS be updated?
There is no fixed or mandatory expiry period (such as a three or five year interval) for the validity of an SDS. However, Article 31 of the REACH Regulation requires the supplier to update the document without delay when the following circumstances arise:
- New hazard information: When new data becomes available on risks to health or the environment, or new risk management measures.
- Changes in legislation: Following the granting or refusal of an authorisation under the REACH regulation or the imposition of specific restrictions.
- Reclassification of the product: When an update to the CLP Regulation modifies the official classification or the concentration limits of any of its components.
Keeping Safety Data Sheets up to date and accessible in the laboratory is an indispensable requirement for operational safety, operational efficiency and success in any quality audit and labour inspection. Integrating this information with a standardised working protocol and the use of high-precision equipment guarantees a safe and highly efficient environment.
