Fume Hoods

Introduction to Chemical Fume Hoods

Chemical Fume Hoods, when used properly and kept in optimal working order, provide an important engineering control that protects users from inhalation of hazardous vapors and gases. Environmental Safety provides training and labeling to help people use fume hoods correctly. You can find the on line course at our

Train and Inform Lab Personnel

Supervisors are responsible for making sure that all personnel receive the appropriate safety training before entering the lab or whenever new procedures or hazards are introduced. Refresher training is best provided at regular intervals. Document any lab-specific training that is provided so it can be audited at any time.

Compressed Gases

Compressed gases have the potential for creating hazardous working environments.  When compressed gases are not handled and used properly, there is the potential for injuries or accidents to occur.  

Injuries may include:

  • the displacement of oxygen from a leaking gas cylinder,
  • fires or injuries caused by flammable gas ignition,
  • inhalation of a toxic or asphyxiating gas, or
  • flying objects accelerated by an explosion or pressure release.


Laboratory Supervisor Responsibilities

Laboratory Supervisors and Lab Safety Officers play critical roles in maintaining a culture of safety at UVM. 

The ultimate goal is to ensure the safety of workers while remaining in compliance with all federal, state and local regulations. UVM strives to promote on-going research productivity and excellence in education.

Personal Protective Equipment (PPE)

Personal Protective Equipment (PPE) is the last line of defense against laboratory hazards. PPE should be considered only after Engineering and Administrative Controls have been examined.  In order for PPE to protect the user, it must be stored, maintained, and worn properly.  Since PPE can fail, those who wear it should be trained to understand its limitations.  

Incident Reporting

UVM encourages the reporting of all injuries and near misses in the workplace. This helps the Risk Management department to follow up with injured persons swiftly so they can help them get the proper care that they might need. Reporting also helps to prevent similar accidents from taking place in the future. 

Nano Materials

Nanotechnology is the science and technology of precisely manipulating the structure of matter at the molecular level.

A nanometer is a thousandth of a micron and a micron is a thousandth of a millimeter, so a nanometer is a millionth of a millimeter or 10-9 meters. To be classified as a nanomaterial (NM), the material must be less than 100 nm in size in at least one direction. 


Cryogenic Liquids: An Overview

A cryogenic liquid is defined as a liquid with a normal boiling point below -240°F (-150°C, 123°K). The most commonly used industrial gases that are transported, handled, and stored in the liquid state at cryogenic temperatures are argon, helium, hydrogen, nitrogen, and oxygen.

Sustainability and Pollution Prevention

Environmental Health and Safety works closely with the UVM Office of Sustainability to help meet UVM's sustainability goals. Research laboratory activities can play a key role in reducing greenhouse gas emissions and lowering electricity usage overall.
