Danger - Battery Charging Area - Wear PPE - No Smoking - No Naked Lights - Safety Signs by Caledonia Signs

Warn and instruct people in areas where batteries—particularly large industrial types such as those used in forklifts, backup power systems, or electric vehicles—are being charged. These environments can present multiple hazards, including the release of explosive hydrogen gas, corrosive electrolyte spills, and electrical risks. The sign delivers three critical messages at once: the area is hazardous, protective equipment must be worn, and ignition sources are strictly prohibited.

This sign should be placed at the entrance to designated battery charging zones and in visible positions within the area itself, such as on walls, charging stations, or equipment racks. Common settings include warehouses, distribution centers, workshops, transport depots, and renewable energy storage facilities. Positioning the sign ensures that anyone entering the space is aware of the risks before approaching the charging equipment, and it reinforces safe behavior for workers who regularly operate there.

The primary reasons for using this sign are safety and compliance. Hydrogen gas from charging batteries can ignite explosively in the presence of sparks, flames, or smoking materials, so the prohibition on “No Smoking – No Naked Lights” is a direct fire and explosion prevention measure. The “Wear PPE” instruction reminds workers to protect themselves from acid splashes, chemical burns, and electrical hazards by using appropriate personal protective equipment such as safety glasses, gloves, and face shields. In many workplaces, these warnings are also a legal requirement under occupational health and safety regulations.

For maximum effectiveness, the sign should be made from durable, chemical-resistant materials and mounted at eye level where it is clearly visible to anyone entering or working in the area. It should be combined with good ventilation, proper training, and safe operating procedures to minimize risks. When displayed correctly, this sign acts as both a warning and a procedural reminder, helping to prevent accidents, injuries, and property damage in battery charging environments.
