Risk of damage to health and property damage.

Leaking acid can cause chemical burns. Oxyhydrogen gas that results from charging can lead to an explosion.

Use personal protective equipment.
Pay attention to the information and operating instructions on the battery.
Touch the vehicle body before touching the battery in order to prevent sparks from static discharge.
Keep countermeasures ready.
Only perform battery procedures in suitable and well-ventilated locations.
Procedures which produce sparks, like sanding, welding, separation procedures and open flames are prohibited.
Batteries showing the "ALI (Acid Level Indicator)" in a bright yellow must be replaced. These cannot be tested or charged and a jump start cannot be given.
Do not place any tools on batteries.
Do not tilt batteries if electrolyte can leak from the vent openings.
It is relevant for safety reasons to which side the battery vents!
For applications in which a gas breather hose is used, pay attention to the correct seating of the gas breather hose and that the vent opening is closed on the opposite side.
