Plastic Secondary Container Shatters Due to Dry Ice Sublimation

May 28, 2019
What happened?

A researcher packaged a microgram crystalline sample with dry ice to ensure sample integrity. The crystalline sample was first placed inside a glass vial, which was subsequently housed inside a plastic secondary container with a screw cap. The researcher placed dry ice around the glass vial inside the secondary container before loosely capping the top to vent.

When it came time to take out the glass vial, the researcher found that the secondary container was stuck, even though the cap was originally loosely screwed.

The researcher recruited the help of a staff...

Respiratory Protection Program

Office of Environment, Health & Safety
2018

EH&S evaluates workplaces for possible airborne hazards and recommends ways to reduce these hazards when found. When appropriate, EH&S will fit campus workers with respirators and provide annual training on their proper use. This program is administered in cooperation with University Health Services. UHS evaluates a person's ability to safely wear a respirator prior to a respirator being issued. For more information contact EH&S at ehs@berkeley.edu.

Respiratory Protection

Office of Environment, Health & Safety
2023

There are several ways to protect against exposure to airborne contaminants. The most effective are engineering and administrative controls. (Engineering controls can include measures such as increasing ventilation or installing a fume hood; administrative controls involve changes in work procedures.) The law requires that these controls be considered before employees are issued respirators. If engineering and administrative controls are infeasible, respirators can be assigned.
