Yes, and we did that too to some extent. The particular equipment that gave me issues was designed to use the room’s air to cool UV lamps… very hot UV lamps. So, we had no option but re-do a portion of the duct work.

The last lab remodel I oversaw, needed to include ventilation upgrades to meet the room temperature requirements of heat generating test equipment. The equipment manuals were my best tool in getting that done. Scientific principles would
have been my worst tool to use.
OSHA standard is silent on indoor temp/humidity requirements. There’s an OSHA letter that states temp/humidity is a matter of “comfort” and although they do have recommendation, they won’t enforce it. However, OSHA standard does have inhalation
limits. Since evaporation rates go up when RT goes up. You could argue that constant temperature and ventilation have a synergistic effect on reducing the inhalation exposure. You could go as far as presenting some hypothetical calculations using select chemicals
in your stockroom.
OSHA does mention uncomfortable indoor temps when talking about ergonomics. See Appendix III:2-1 of OSHA Technical Manual (OTM) Section III: Chapter 2
https://www.osha.gov/otm/section-3-health-hazards/chapter-2
You might find the seemingly brush-off answer has a deeper root on something that isn’t easily fixable. If you can get them to talk candidly, they’ll probably tell you what information they need from you to justify changes and secure funds.

Hello all,
I am looking for resources, personal experience, anything that will help me with talking to facilities about maintaining an appropriate temperature in a science building. Obviously temperature (and humidity) are a concern. We can all agree
that climate change is a thing and that we are going to get fluctuations in temperature. I’m having a difficult time convincing some people in facilities that having high temperatures in a science building is more than just an inconvenience. I’m looking for
documentation, anything that will help my cause in convincing them that when we reach high temps (we were at 89.6 F last week in my flammable storage room) something needs to be done.
I’ve been searching the DCHAS website but not finding what I am looking for. I’ve looked at SDS’s until I am blue in the face, but they tend to say “keep in a cool, well-ventilated location”. What does “cool” mean? Facilities tells me I
should move all my chemicals to a refrigerator when it gets hot. Obviously that is not feasible.
Any insight you can provide is a appreciated.
Thank you.
