Lead

Updated March 1, 2024

Lead is a malleable, blue-gray, heavy metal that occurs naturally in the environment. Lead is found in many forms and can be hazardous when inhaled as a dust or fume, or accidentally ingested after contact directly or with contaminated surfaces.

While inorganic lead does not readily enter the body through the skin, it can enter the body through accidental ingestion (eating, drinking, and smoking) via contaminated hands, clothing, and surfaces.

Many laboratories use hazardous chemicals that are purchased in large quantities and then transferred into smaller secondary containers (e.g., vials, flasks or bottles), or prepared as diluted solutions or mixtures for use.

If your laboratory uses secondary containers filled with chemicals, the secondary containers must comply with OSHA’s Hazard Communication Standard for Labels and Pictograms.

Liquid Nitrogen and Alarms in University Research Space

 

This report is intended to provide guidance on identifying and evaluating potential risks related to storage of liquid nitrogen in laboratory space, and how to best mitigate those risks at the University of Washington. This paper provides an analysis of the available literature on the subject, example calculations of risk, and suggestions of best practices to detect an unsafe environment from liquid nitrogen and other cryogenic material spills and releases in rooms and spaces.
