Keep informed about workplace hazards with proper labeling techniques and safety posters available from Safety Emporium.

This term usually appears on Section 10 (stability and reactivity) of a Safety Data Sheet as a symptom of over-exposure. Many chemical vapors can induce dizziness, light-headedness or stupor following inhalation. At higher concentrations, exposure can cause coma or death. It is important to recognize when you (or your coworkers) are becoming impaired from exposure to chemical vapors so you do not pass out before removing yourself to fresh air.

Stupor may also arise from skin exposure or ingestion. As always, read the Safety Data Sheets of the chemicals you work with so you know the symptoms of exposure and take proper precautions to avoid exposure in the first place.
