When charging an electric forklift, what must be strictly avoided?

The correct answer is that fire or sparks must be strictly avoided when charging an electric forklift. This is essential for safety reasons, as electric forklift batteries contain flammable materials and potentially explosive gases can be emitted during the charging process. The presence of fire or any source of sparks can lead to hazardous situations, including fires or explosions, posing a significant danger not only to the equipment but also to the personnel involved.

Maintaining a safe charging environment free from any ignition sources is crucial for ensuring the safety and longevity of the equipment. Vulnerabilities in the charging process can have severe consequences, making strict adherence to this guideline imperative in warehouse and industrial settings.

While other aspects such as low temperatures, overcharging, and water exposure are important considerations, they do not pose the immediate and critical risk associated with fire or sparks during the charging process.
