when should you look up a chemical's sds/msds
You should look up a chemical’s SDS/MSDS before you ever use, store, mix, transport, or dispose of that chemical, and again any time something changes (new product, new supplier, new procedure, or an incident like a spill or exposure).
What SDS/MSDS Is For
- It explains key hazards: health, fire, reactivity, and environmental risks for that specific chemical or product.
- It gives critical instructions for PPE, safe handling, storage, first aid, and spill response.
Situations When You Must Look It Up
Look up and read the SDS/MSDS:
- Before first use of any hazardous chemical
- When a new chemical or product is brought into the lab, shop, plant, or workplace.
- When you start a job or assignment that uses chemicals you haven’t worked with before.
- Before changing how you use it
- New process (heating, spraying, mixing, pressurizing, scaling up).
- Using higher quantities or in a more confined/poorly ventilated space.
- Combining it with other chemicals, even “common” ones, where reactions are possible.
- Before storage or transport decisions
- To know proper storage temperature, ventilation, segregation (e.g., away from oxidizers or acids), and container type.
* To check incompatibilities that could cause fires, explosions, or toxic gas formation.
- Whenever there’s an emergency risk
- You have or could have a spill , leak, or accidental release.
- Someone is exposed (skin contact, inhalation, splash in eyes, ingestion).
- You need to know what to tell first responders and medical staff during an incident.
- When regulations or workplace rules require it
- OSHA and similar standards require SDSs to be readily accessible for all hazardous chemicals used at work, on every shift.
* Many workplaces expect you to review the SDS as part of required safety training or before being authorized to use a chemical.
When You Don’t Usually Need One
- Truly household-type products (like a small bottle of regular dish soap or window cleaner) used rarely and exactly as a household would, in an office-type setting, often do not require maintaining an SDS at work under some institutional policies.
- But if you use those same products frequently, in bulk, or as part of your job , they are treated as workplace chemicals and you should have and read the SDS.
How Often to Re-check It
- Check for a new or revised SDS when:
- The manufacturer changes the formulation.
- New hazard information becomes available.
- Your organization updates suppliers or sources.
- Periodic refreshers (e.g., before big projects or after a long gap in using the chemical) help keep handling and emergency steps clear in your mind.
