Accurate SDS Authoring: The Foundation of Chemical Safety
A Safety Data Sheet (SDS) is more than a regulatory requirement — it’s a critical communication tool that protects workers, consumers, and the environment. Yet, many companies struggle to maintain fully compliant, up-to-date SDS documentation.
At Experien Health Sciences, we’ve reviewed thousands of SDSs across industries and found that even experienced teams often make the same avoidable mistakes. Here are the top 10 most common SDS authoring errors — and how to prevent them.
1. Using Outdated MSDS Formats
Many organizations still rely on legacy MSDS templates that don’t meet the current GHS (Globally Harmonized System) requirements.
-
The Problem: Incomplete or inconsistent section layouts, missing hazard statements, and lack of pictograms.
-
The Fix: Always use the standardized 16-section SDS format under GHS, aligned with regional regulations such as OSHA HazCom 2012, EU CLP, or WHMIS 2015.
2. Incorrect Hazard Classification
Accurate hazard classification is the backbone of SDS compliance.
-
The Problem: Misclassifying hazards (e.g., labeling a substance as irritant instead of corrosive) can lead to legal and safety issues.
-
The Fix: Use validated data and regulatory tools to classify chemicals under GHS criteria. Engage qualified toxicologists and chemists to verify classifications.
3. Incomplete Toxicological or Ecological Data
Sections 11 (Toxicology) and 12 (Ecology) are often neglected or oversimplified.
-
The Problem: Missing LD₅₀ data, incomplete chronic toxicity details, or outdated environmental impact information.
-
The Fix: Reference authoritative sources such as ECHA, EPA, and OECD databases, and ensure all endpoints are supported by current scientific data.
4. Mixing Up Regional Regulatory Requirements
Each region interprets GHS slightly differently.
-
The Problem: Using an EU-classified SDS in the U.S. or failing to localize phrases and limits.
-
The Fix: Tailor SDSs for each region (U.S., EU, UK, Canada, Australia, etc.) using region-specific phrases, exposure limits, and labeling conventions.
5. Inconsistent Labeling Information
The SDS and product label must always match.
-
The Problem: Conflicting hazard statements, signal words, or pictograms between SDSs and packaging.
-
The Fix: Implement internal document control to ensure all labels and SDS versions are synchronized after classification updates.
6. Copy-Pasting Without Validation
Reusing SDS content without verifying accuracy is a common shortcut.
-
The Problem: Incorrect data carried over from unrelated materials, non-compliant phrases, or outdated regulations.
-
The Fix: Review every section for accuracy and compliance. Never reuse data unless verified against current chemical composition and regulations.
7. Neglecting Section 16 – Other Information
Section 16 may seem minor, but it’s essential for transparency.
-
The Problem: Leaving this section blank or omitting references, revision history, or disclaimers.
-
The Fix: Include the SDS revision date, data sources, and version notes to demonstrate traceability and due diligence.
8. Failing to Update SDSs After Product Changes
An SDS must reflect the current formulation and hazard profile of a product.
-
The Problem: Outdated SDSs remain in circulation after ingredient changes, creating compliance risks.
-
The Fix: Update SDSs immediately following any formulation change, new regulatory data, or GHS revision. Maintain a review cycle (at least every 3 years).
9. Missing Exposure Controls or PPE Recommendations
Incomplete Section 8 data can lead to unsafe workplace practices.
-
The Problem: Generic or missing information on exposure limits, ventilation, or personal protective equipment (PPE).
-
The Fix: Include accurate exposure limits (e.g., OSHA PELs, ACGIH TLVs) and specify PPE for real-world scenarios.
10. Ignoring Multilingual Requirements
Global distribution demands multilingual compliance.
-
The Problem: Providing SDSs only in English when local laws require translation.
-
The Fix: Translate SDSs into required local languages (e.g., French for Canada, Spanish for Latin America, German for EU) using certified translators familiar with GHS terminology.
