Fume Hoods: Function and Purpose

With many accidents involving harmful and toxic chemicals, a fume hood Australia providers offer is more important than ever.

In 2015, five students at a Fairfax County high school were burned while performing a chemistry lab demonstration. In 2016, a teacher at Mandwandwe High School in the Nkulumane suburb in Bulawayo died after inhaling poisonous fumes he was working with at the science laboratory.

Both cases, despite geographical differences, have one thing in common – fume hoods. In the first case, the spread of ethyl alcohol vapours may have been prevented if a ventilation hood was installed. In the second case, the problem was the improper storage of chemicals that should have been kept in a bottle or fume hood.

To prevent the same accidents from happening in laboratories or work areas dealing with chemicals in Australia, a fume hood must be installed. As what the Assistant Professor of Radiology and Chemistry at the University of Missouri, Mark Lee, said a fume hood differentiates a mere room from a chemistry lab.

How does a fume hood work?

A fume hood in Australia and anywhere else around the world removes potentially hazardous particles and vapours from the air to keep people working in a facility safe. This is also a way to prevent particles and vapours from interfering with what lab workers are doing.

Fume hood can also refer to a ventilated enclosure that houses gases, fumes, and vapours, as in the case of a laboratory fume hood Australia offers. It is connected to an exhaust fan that pulls air and airborne contaminants out of a laboratory.

Types of Fume Hoods

Fume hoods come in different varieties, with each one having its share of pros and cons.

  • Hoods that use ducts make great work of pulling out contaminants but are less portable and are often expensive.
  • Smaller fume hoods are mobile, practical, and affordable. The only downside is that they are not suitable for areas where chemical use is significant and you might need to use more in such situations.
  • Laboratory fume hood looks like a cabinet but is made up of filters that clean and recirculate air.
  • Recirculating fume hood, as the name suggests, filters air as and sends it back to the atmosphere without the harmful particles. It is typically less expensive because ducts are not required.

Many school laboratories prefer the smaller and more portable Australia fume hood as this can be placed in each station, allowing groups of students to work with chemicals at one time and remain safe. Click here Aircare Extraction Systems for more information.

Even with fume hoods installed, however, following best practices in working and handling with chemicals remain vital to ensure safety and protection.

Safety Standards in a Laboratory

Use safety goggles

The man who studied potassium, Joseph-Louis Gay-Lussac, suffered permanent vision damage and temporary blindness when the highly reactive element exploded. This happened at a time when eye protection is still unavailable.

Don’t breathe fumes

When dealing with chemicals that produce dangerous fumes, avoid sucking or inhaling too hard. Even with fume hood Australia offers is installed, close contact with fumes can still prove fatal.

Handle chemicals with care

This is a no-brainer, what with people being more aware of which chemicals are toxic and which are not. Whichever is the case, however, remember to wash your hands and decontaminate when needed every single time.
