Hi,
Explosion proof fridge and freezer are designed to be used in room that are rated as “explosion proof” (i.e. lights, switches, equipment are all rated as explosion proof). Building code numbers might
be different from Countries.
Explosion proof fridges are “hard wired” to the electrical system (i.e. not plugged type).
Hope this help

Hello Rachel and congratulations on your new role!
inventory Systems
·
We use Vertere for our chemical inventory (which used to be conducted biannually and now that I have been doing it for over ten years, it is now conducted annually. I do all of our procurement, receiving
and delivery, so our inventory happens organically all year round through that process as well). I have been very pleased with the customer service from Vertere, as they are always immediately responsive. I am unsure of their cost comparison in regard to
the other options. I did just have to buy a new scanner and that was rather pricey (around $2000 if I recall correctly), but we had the same one for well over 10 years. There is a mobile option where you can use your mobile device to scan the barcodes, so
that would be handy and eliminate the need for the scanner. We have a Zebra printer to print our barcodes and that is old and I have never replaced it.
Explosion vs Flammable Fridge/freezers
·
We have the flammable fridge/freezers in our labs and I am interested to hear from anyone who has the feedback on the explosion proof.
Student Lab Safety
·
I talk about this in my student and faculty/staff annual training sessions and we actually have a demonstration where I set fire to them or have one of the participants do it. Our Lab Safety Team made
videos doing this last year. I did find some papers, but the one with photos was older and of someone who was smoking and caught her nail on fire and subsequently had to get her finger amputated. If you respond off list, I am happy to share whatever I have.
·
I also have a model of a hand that I put a nail on and have it poking through the finger of the glove, to demonstrate how long nails can compromise the integrity of the glove. It has taken awhile to
see less of the acrylic nails, but we rarely see them now. Instructors share with students the first week of lab that they are not recommended and it is also in our Chemical Hygiene Plan.
Hope this helps, feel free to reach out anytime!
