being assembled in a battery, such cases are so very, very rare that they almost may be said to not exist.
Care of batteries is a simple matter, but it must be
done thoroughly and well, and must be done before
trouble has a chance to start. Once it has started — well, that is another story !
Moral : Do youi duty by the batteries and they will do their duty by you.
BATTERY LOCATION.— In the process of charging, storage batteries give off hydrogen gas in considerable quantities. This gas is inflammable, and when mixed wTith air is explosive; also it is not healthful to breathe in quantity. It therefore follows that batteries must be located In a well ventilated room — never in a confined place. They must be so located that they will be readily accessible for examination and care.
As has been said, the battery gives off quantities of an explosive gas when charging. There may be more or less of this gas in the cells when they are not on charge. It therefore is unsafe to have any open flame or spark, such as a candle, match, lantern, lighted cigar, cigaret or pipe near the batteries. This is particularly true while the battery is on charge, or for half an hour thereafter.
The man who attempts to examine the water level of a cell, using a lighted match or other open light source, has no one but himself to blame if there is an explosion and he is badly burned or blinded for life.
If possible, have your batteries located on a table or shelf about the height of an ordinary table. If possible, have this shelf or table located where it is normally well lighted. Plenty of light and convenience in location
