Prudent practices suggests that all chemicals (whether commercial or lab samples) be labeled with:
Compound name (written out, not a formula)
Name of generator
Large Container Labeling
In an effort to improve our compliance with hazard labeling, the JST has developed this sticker, which can be placed on any large container (fridge, cabinet, secondary containment). The goal is to quickly and easily alert visitors, facilities management, and emergency responders to hazards.
To learn more about hazard classes, take a look at our Know Your Hazards presentation.
The Lab entry sign provides a consistent look and consolidates several signs. The sign is intended to alert emergency responders, facilities staff and visitors to potential hazards and precautions for entry. Follow the DEHS link for more information about the template.
If the laboratory should not be entered temporarily, please post a "Do Not Enter" sign at each laboratory entrance.
Labeling individual vials and samples with each of these items can be challenging. For small samples, we recommend that labs develop their own labeling system for the identity of the sample and the generator. To indicate hazards, the underlined letters in hazards on the sticker may be used. For example, a sample that was acidic would be labeled with a lab-specific code as well as an "A" with a circle around it. A simple buffer solution with non-toxic salts would be labeled "LH" inside a circle for Low Hazard.
