Why should metal tools be avoided around the battery pack?

• A. Metal tools are more expensive.
• B. Metal tools can bridge HV connections and cause arcing or short circuits.
• C. Metal tools attract dust.
• D. Metal tools are too heavy.

Answer: (B)

Around a high-voltage battery pack, stored energy can flow if a conductive path is created. Metal tools are conductive, so using them near live HV connections can bridge circuits accidentally. If a tool touches two terminals or a terminal and a grounded surface, it can cause a short circuit, leading to a surge of current, heat, and potentially an arc. Arcing can damage components, ignite materials, or cause electric shock. That’s why metal tools should be avoided around the battery pack; nonconductive tools or insulated tools designed for HV work, along with proper de-energization procedures, are used to reduce this risk. The other options don’t address the electrical hazard: cost, dust attraction, or weight don’t directly create the dangerous short or arc scenario.
