Remember these safety measures of lead acid battery
Lead acid battery uses a reversible chemical reaction to store energy and it uses a combination of lead plates or grids and an electrolyte consisting of a diluted sulphuric acid to convert electrical energy into potential chemical energy and back again. The electrolyte of lead-acid batteries is hazardous to your health and may produce burns and other permanent damage if you come into contact with it.
Lead acid batteries can be dangerous because they vent hydrogen and oxygen gas during operation. The following points should be remembered:
1. Keep the electrolyte in flooded cells at the correct level with distilled water, to make good losses due to evaporation and gassing.
2. Use no materials or finishes which will be attacked by acid in the battery room. Spilled acid and acid vapour given off during gassing, will quickly corrode most exposed metals other than lead. Use an asphalt floor where possible and coat wooden surfaces with anti-acid paint.
3. Ventilate the battery room well, if necessary using carrion-proofed fans.
4. Do not allow a naked flame in the room; and prevent sparking by switching off a circuit before connecting and disconnecting. The gases present are explosive when in the correct proportions.
5. Mop up spilt acid immediately and wash with soda solution. Acid on clothing will quickly cause holes to appear.
6. When mixing acid for the initial charge of new cells, always add acid to water, and not the reverse.
7. Watch cell temperature, as excessive heat will damage lead-acid cells. Acid temperature should not exceed 30℃.
8. Keep battery terminals clean and coated with petroleum jelly.
9. Remember that a short circuit across the battery or cell terminals can result in very high currents which may result in fire or burns. Use only insulated tools and take great care not to allow terminals to connect together inadvertently.
For your safety, keep these points in mind. Maybe you pick up a battery at will. It is likely to be a lead acid battery. As for the wide use of lead acid batteries, these safety measures are required to know for everyone who has these batteries. Take care of batteries, and they will take care of you.
