Fire Safety and Emergencies

The Michigan Technological University emergency guide applies for all facilities on campus. In case of a fire or another emergency, refer to the University EMERGENCY GUIDE.

The emergency phone number is 911.

Instrument Settings

As a result of the sophistication of the mass spectrometers and microscopes, the user interfaces of these machines are often complex. Many of the available controls are used for calibration or maintenance and do not usually require adjustment during regular use. For this reason, this facility expects that users do not attempt to make setting adjustments using controls with which they are unfamiliar.

Precautions

  • If an irregular setting is required, request assistance.
  • After each use, return the instrument to its default settings.
  • If the user is unable to return an instrument to its regular settings, report the problem.

The emergency phone number is 911.

Compressed Gasses

During normal usage, users should not disturb the compressed gas tanks in ChARM. Please ask for assistance if intervention with gas supplies is necessary.

Properties of liquid Argon

Liquid argon is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid argon has a boiling point of –303°F (–186°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial. This relatively low temperature can result in damage to human skin or eyes upon contact.

Argon gas is colorless and odorless. On vaporization, liquid argon expands by a large factor.  This expansion can cause an inappropriately sealed or damaged container of liquid argon to explode and/or displace the oxygen in the room. This may lead to suffocation without warning.

Precautions

  • Do not disturb the compressed gas tanks
  • When handling liquid argon, always wear eye protection, cryo-gloves, and appropriate leg and foot protection.
