seek medical attention.
2.3 If battery acid comes in contact with your eyes, flush your eyes immediately and get medical attention.
2.4 Neutralize any acid spills thoroughly with baking soda before attempting to clean up.
2.5 Remove all personal metal items from your body, such as rings, bracelets, necklaces, and watches. A battery can produce a short circuit current high enough to weld a ring
to metal, causing a severe burn.
2.6 Never smoke or allow a spark or flame in the vicinity of the battery or engine.
2.7 This product contains a lithium-ion battery. In case of fire, you may use water, a foam extinguisher, Halon, CO2, ABC dry chemical, powdered graphite, copper powder, or soda (sodium carbonate) to extinguish the fire. Once the fire is extinguished, douse the product with water, an aqueous-based extinguishing agent, or other nonalcoholic
liquids to cool the product and prevent the battery from re-igniting. NEVER attempt to pick up or move a hot, smoking, or burning product, as you may be injured.
