Reading the safety data sheet
Updated
On this page8
Why the order is fixed
Because the standard says so. The hazard communication requirement sets the sections and their sequence, which means every SDS from every supplier answers the same question in the same place. Once you know where to look, reading one takes a couple of minutes rather than an afternoon.
The four that matter most here
- Section 2, hazards identification. The signal word, the hazard statements and whether it is classified as a sensitizer.
- Section 7, handling and storage. What the container has to do and what the product must not be stored near.
- Section 8, exposure controls and personal protection. Which glove material, which respirator cartridge, what ventilation.
- Section 10, stability and reactivity. What it reacts with, and for resins the conditions that make the cure run away.
Section 8 is the one that decides your gloves
Glove material matters and the SDS names it. Choosing by what is in the drawer rather than by what section 8 says is the most common protective failure in this craft, and it is the one that feels like protection while providing none.
It is product specific, not resin specific
Two epoxies from two suppliers are not the same chemical and may not carry the same classification. A summary you read once about epoxy in general is not a substitute for the sheet for the bottle in your hand.
Keep them
If you have workers, keeping the sheets accessible is a requirement rather than good practice. If you do not, keep them anyway: it is the document you will want in front of you the day something goes on skin or in an eye.
They change
Suppliers reformulate and reclassify, and the sheet that came with last year’s drum describes last year’s product. Pull the current one when you reorder rather than filing the old one forever.
Section 4 is the one to have read in advance
First aid measures, because the moment you need it is the moment you cannot stop to read sixteen sections. Resin in an eye has a specific answer and knowing it beforehand is the difference between acting and searching.
