HD-11 and Hydrogen
Lead-Acid batteries generate Hydrogen (H2)
gas during recharging
At ordinary temperature and pressure
Hydrogen it is an odorless, colorless gas
Hydrogen burns readily in air over a wide
range of concentrations: from 4 to 75% by
volume
Hydrogen gas is lighter than air and may
accumulate high in a room or building
Sources of Hydrogen include battery charging stations for golf
carts, forklifts or automobiles, battery back-up in IT rooms or
telecommunication towers and fuel cell or hydrogen powered
vehicles and maintenance facilities
