If you're trying to write a chemical safety summary and don’t know where to start, here’s what matters most: keep it short, clear, and useful. The goal is to explain what the chemical is, what makes it dangerous, and how to handle it safely without using confusing technical terms.
Whether it’s for a Safety Data Sheet (SDS), lab document, or safety report, this guide will show you exactly how to write a chemical safety summary that’s easy to understand and meets safety rules.
How to Write Summaries for Chemical Safety (Step-by-Step)
1. Know Who You’re Writing For
Start by understanding your audience. Is it a lab tech, warehouse staff, or a safety coordinator? The summary should match their knowledge level. For non-experts, keep sentences short and simple. Avoid abbreviations or formulas unless absolutely necessary.
2. Gather the Key Info First
Look at the chemical’s full documentation and pick out the essentials:
- Main hazards (flammable, toxic, corrosive)
- How exposure could happen (inhalation, skin contact)
- What personal protective equipment (PPE) is needed
- What to do in case of a spill or accident
This information is often found in Sections 2, 7, and 8 of the SDS.
3. Write the Hazard Summary in Plain Language
Use simple words that anyone can understand. Avoid overloading your summary with technical terms. For example, say “can burn skin” instead of “causes dermal corrosion.”
A strong hazard summary is often just two to three short sentences describing what the chemical does and why it matters.
4. Add Safe Handling and Emergency Instructions
Mention how to use the chemical safely. Include where to store it and what actions to take if there’s a spill or accident. You don’t need every single detail. Just include the steps that matter most for safety in everyday use.
Also include key PPE such as gloves or goggles and whether special ventilation is needed.
5. Make the Summary Easy to Read
Use bold or italic text to highlight the most important points. Keep sentences short and break the text into short blocks. Avoid giant paragraphs that are hard to scan, especially in documents like SDSs or lab protocols.
If bullet points are allowed in your format, use them sparingly. For example, use them to list PPE or spill steps.
6. Follow Local Safety Regulations
Make sure the summary aligns with current notices for SDS format and content, and with the hazard classification system based on GHS 7 compliance.
The SDS requirements are set out in the Safety Data Sheets Notice, and all substances now follow the updated notices after the transitional period ended on 30 April 2025.
7. Review and Finalize
Before publishing the summary, double-check it. Is it accurate? Is it easy to understand? Will it make sense to someone using the chemical on the job?
You should also review it with a supervisor or another safety expert. If the SDS or any usage guidelines change, the summary should be updated to match.
Which documents contain Chemical Safety Summaries
You can usually find a chemical safety summary inside documents you already use.
- Safety Data Sheet (SDS): Includes a short chemical safety summary, with Sections 2, 7, and 8 covering key hazards, safe handling, and emergency steps under the 16-section format.
- Risk assessment, lab protocol, or local procedure: May also include a one-page summary for quick reference.
In both cases, the summary section gives a quick overview of the chemical’s key dangers and how to manage them. When done well, it helps both workers and safety officers make faster, safer decisions.

Summary of Hazards and Safe Use
Toluene is a highly flammable liquid that can irritate skin and eyes and may cause dizziness if inhaled. Vapours can form explosive mixtures with air. Use only in a well-ventilated space and keep it away from heat, sparks, or flames.
Wear chemical-resistant gloves and goggles. Store tightly closed in a cool, dry place. For spills, absorb with non-flammable material and ventilate the area.
Best Practices for Clarity and Compliance
Use plain, direct language. Stick to what’s important and write like you’re talking to someone on your team, not a lawyer or chemist. Structure matters too. Bold important terms, space out the sections, and keep the layout simple.
Don’t try to cover every possible detail. Your job is to summarize, not to copy the entire SDS. Focus on what people need to stay safe.
Regularly review your summaries to keep them current. Notices and guidance can change, and so can how a chemical is used at work.
Building a habit of writing better summaries makes safety easier and more effective for everyone on your team.
Frequently Asked Questions (FAQs)
1. What is the main goal of a chemical safety summary?
The goal is to give a quick, clear explanation of the chemical’s main hazards and how to handle it safely. It should help someone understand risks and take proper precautions.
2. How long should a chemical safety summary be?
It should be short, ideally under 150 words. Just include the most important points like hazards, protective measures, and emergency actions.
3. Who usually writes the chemical safety summary?
Anyone responsible for workplace safety, including lab managers, EHS staff, or SDS authors. It can also be added by someone updating a lab protocol or safety sheet.
4. Can I copy the SDS text into the summary?
No, the summary should not be a direct copy. It should simplify and highlight key info from the SDS in language that’s easy to understand.
5. Do I need to update the summary if the SDS changes?
Yes. If the chemical’s hazards, uses, or safety guidelines change, your summary should be updated to match the latest SDS version.
