The Safety Data Sheet (SDS), also known as MSDS, is an important document for conveying chemical safety information. The core of its review is to ensure that the content is accurate, complete, and compliant, effectively guiding the safe use, storage, transportation, and emergency handling of chemicals. The following are key review points for reference:
 
I. Core Review Principles
- Compliance: Conforms to relevant national/regional standards (such as China's GB/T 16483, EU CLP regulations, US OSHA standards, etc.).
- Completeness: Includes the 16 core elements required by the standard, with no omissions or ambiguities in key information.
- Accuracy: Chemical information, hazard descriptions, and protective measures are consistent with the actual physical and chemical properties of the substance, and data sources are reliable.
- Practicality: The language is easy to understand, the operating instructions are clear, and users can quickly grasp the key safety points.
 
II. Key Review Content (divided into 16 sections of SDS)
1. Chemical and Company Identification
- Review: Check if the chemical name (including CAS number, common name, trade name), and manufacturer information (name, address, contact information) are complete and accurate; whether a "24-hour emergency contact number" is clearly indicated.
2. Hazard Identification
- Review: Check if physical hazards (such as flammability, corrosiveness), health hazards (such as poisoning, carcinogenicity), and environmental hazards are clearly listed; whether GHS pictograms, warning words (such as "Danger", "Warning"), and precautionary statements are included; whether the hazard description matches the components and actual properties.
3. Composition/Information on Ingredients
- Review: Check if the chemical name, CAS number, and concentration range of hazardous components are listed; for mixtures, whether the component information with a concentration ≥0.1% (health hazard) or ≥1% (physical hazard) is clearly indicated, with no concealment.
4. First-aid Measures
- Review: Check if specific first-aid methods are provided for different exposure routes (skin, eyes, inhalation, ingestion) (e.g., "Immediately remove contaminated clothing and rinse skin with plenty of water for more than 15 minutes"); whether "medical advice" is clearly indicated (e.g., "If dizziness occurs, seek medical attention immediately"), avoiding vague statements (e.g., "timely treatment").
5. Fire-fighting Measures
- Review: Check if key parameters such as flammability, flash point, and explosion limits are clearly indicated; whether the recommended extinguishing media (e.g., "dry powder fire extinguisher", "do not use water to extinguish fire") are reasonable; whether the protective requirements for firefighters (e.g., "wear self-contained breathing apparatus") are clear.
6. Accidental Release Measures
- Review: Check if the leakage handling steps are specific (e.g., "Isolate the leakage area, restrict personnel entry", "Absorb small leaks with sand, build a dam to contain large leaks"); whether the environmental requirements for collecting and handling leaked materials are clearly indicated to prevent pollution spread.
7. Handling and Storage
- Review: Check if safety precautions during operation (e.g., "Avoid skin contact, wear rubber gloves", "Operate in a well-ventilated area"); whether the storage conditions (e.g., temperature, humidity, isolation requirements from other substances, "Keep away from fire, store in a cool, dry place") are reasonable.
8. Exposure Controls/Personal Protection
- Review: Check if occupational exposure limits (e.g., China PC-TWA, US TLV) are clearly indicated; whether the recommended protective equipment (e.g., respiratory protection, eye protection, skin protection) matches the hazard level (e.g., highly toxic substances require "self-contained breathing apparatus", not ordinary masks).
9. Physical and Chemical Properties
- Review: Check if key physical and chemical parameters are complete (e.g., appearance, odor, pH value, melting point, boiling point, density, solubility, etc.), and whether the data is accurate (can be compared with authoritative databases).
10. Stability and Reactivity
- Review: Check if the stability of the substance under normal conditions is clearly indicated; whether prohibited substances (e.g., "react with strong acids to produce toxic gases") and conditions to avoid (e.g., "decomposition upon heating or exposure to light") are clear; whether the decomposition products include harmful substances (such as toxic gases).
11. Toxicological Information
- Review: Check if key data such as acute toxicity (e.g., LD50, LC50), irritation, sensitization, and long-term toxicity (e.g., carcinogenicity) are included; whether the data sources are reliable (e.g., citing authoritative toxicological databases).
12. Ecological Information
- Review: Check if the hazards to aquatic organisms and the environment (e.g., "highly toxic to fish") are described; whether information on biodegradability and bioaccumulation is included (if applicable).
13. Disposal Considerations
- Review: Check if the waste disposal methods are compliant (e.g., "disposed of by qualified units", "must not be dumped arbitrarily"); whether the pretreatment requirements before disposal are clearly indicated (e.g., "neutralization before disposal").
14. Transport Information
- Review: Check if it complies with transportation regulations (e.g., UN number, shipping name, packing group, transportation prohibitions); whether the special requirements for road/rail/sea/air transport are clearly indicated.
15. Regulatory Information
- Review: Check if relevant national/regional chemical management regulations are cited (e.g., China's "Regulations on the Safe Management of Hazardous Chemicals"); whether the hazardous chemical classification of the substance is clearly indicated (e.g., whether it belongs to "highly toxic chemicals", "easily explosive chemicals").
16. Other Information
- Review: Check if the preparation date and revision date of the SDS are included; whether "data source" and "preparation unit" are indicated to ensure traceability.
 
III. Review Notes
- Verify the consistency between the SDS and the actual substance: Avoid "one product, multiple SDS" or "SDS does not match product" (e.g., inconsistencies between the name, CAS number, and the physical label).
- Focus on timeliness: SDS should be revised in accordance with changes in material properties and regulations. Avoid using outdated versions (generally recommended to update every 3-5 years, or immediately if new hazard information becomes available).
- Use clear language: Avoid excessive technical jargon. Key operational steps (such as first aid and spill handling) should be concise and easy to understand for frontline personnel.
 
By reviewing the above key points, we can ensure that the SDS truly serves as a "safety guidance tool" and reduces the risks associated with chemical use.
