Tools used for servicing nickel-cadmium batteries will be what?

• A. Insulated
• B. Copper-coated
• C. Aluminum-handled
• D. Non-conductive but uninsulated

Answer: (A)

When servicing nickel-cadmium batteries, the safety goal is to prevent any path for current to flow from the battery through the tool into other conducting parts. Insulated tools provide a non-conductive barrier between you and the battery terminals, so if the tool contacts a live terminal you won’t create a short circuit or arc. NiCd packs can deliver high currents, and a simple metal or partially conductive tool could bridge cells or terminals, causing overheating, gassing, or damage. Tools with copper coating or metal handles keep conducting pathways intact, which is why they’re not appropriate in this context. A non-conductive tool that isn’t insulated risks exposure to damaged or compromised insulation, moisture, or wear that can reintroduce conductivity. So insulated tools—with intact insulation—offer the best protection when working around NiCd batteries.
