Wear splash-proof goggles and protective clothing (gloves and aprons). A face shield may also be necessary when handling sulphuric acid in an open system.

Do not store acid in hot locations or in direct sunlight. Pour concentrated acid slowly into water: do not add water into acid. Use non-metallic containers and funnels. Use extreme care to avoid spilling or splashing the sulphuric acid solution. It can destroy clothing and burn the eyes and skin.

Use an eyewash station if the sulphuric acid solution is splashed into the eye. Neutralize spilled or splashed sulphuric acid solution with a baking soda solution, and rinse the spill area with clean water.

If you are interested in battery regeneration and charging batteries, there are some issues to keep in mind. 

Always check the electrolyte level before recharging batteries. If the battery has been outside in cold weather, make sure that the battery is not frozen before recharging it. If the electrolyte is covering the top of the plates, do not add more water. Recheck the fluid level after the battery has been recharged. If water is added, use distilled water, not tap water. 

When vent plugs may need adjustment, follow manufacturers' instructions carefully. 
If the battery has sealed vents, do not recharge the battery with a current greater than 25 amps. 

Tcell is the leading operator in Tajikistan with 2.5 million subscriptions in a highly competitive local mobile market. Tajikistan is a highly mountainous country, where 93% of the territory is covered in mountains and more than half of the population lives at altitudes of over 3,000 meters above sea level. Tcell's high-elevation sites have provided several thousand rural residents in mountainous areas with the unique opportunity to stay connected to the outside world, for the first time in their lives. In these places, Tcell is the only active operator out of the 7 heavily competing mobile networks (for the customers).

Lead-acid batteries contain sulphuric acid and only trained and authorized personnel should handle them. When talking about lead-acid batteries, people usually call sulphuric acid "battery acid" or the "electrolyte".  An electrolyte is general term used to describe a non-metallic substance like acids like sulphuric acid or salts that can conduct electricity when dissolved in water. Lead-acid batteries can produce explosive mixtures of hydrogen and oxygen gases when they are being charged. 

Charge batteries only in approved, ventilated battery-charging areas. Install a safety shower and an eyewash station in a battery-charging area.
