What precaution must be taken when cutting near a battery?

When cutting near a battery, it is essential to disconnect the battery to prevent explosions. The cutting process generates intense heat and sparks, which can ignite flammable gases emitted by a battery, particularly if it is a lead-acid type. These gases, including hydrogen, can form explosive mixtures in the presence of sparks or open flames. By disconnecting the battery before starting any cutting operations, you significantly reduce the risk of ignition and ensure a safer working environment. This precaution is critical for maintaining safety while working in proximity to batteries, as the potential for accidents increases dramatically if the battery remains connected.
