Following a recent basement flood & to stay in business we have had to secure & partition off with studding & plasterboard part of our upper floor office to accomodate approx 80 UPS Batteries. Ventilation is provided by the normal office air con system.

The batteries are on trickle charge but however recently overheated getting up to 30+C. Hot air from the enclosed room was vented into the general office atmosphere over the weekend, however we have had complaints over air quality & asthma attacks following these actions.

I am aware batteries can vent both hydrogen & electrolyte if they overheat (INDG 139 refers)
I now need to check for air quality & in particular assess the emmissions of these two substances as it appears our "temporary" power solution may be in place for a while. I would appreciate any advice on the best method & products for assessing the amount of hydrogen & elctrolyte which employees may be exposed to.
