To ensure safety with electrostatic discharge sensitive devices, what should be done with all hand tools?

The most effective method to ensure safety with electrostatic discharge (ESD) sensitive devices is to properly ground all hand tools prior to use. Grounding tools reduces the risk of static electricity build-up, which can damage sensitive components during handling and maintenance. When tools are grounded, any static charge that might accumulate on them is safely dissipated, minimizing the possibility of an ESD event.

Other options, while they may reduce risk in certain contexts, do not address the fundamental concern of grounding. For instance, placing tools on an insulating surface may prevent static charge from transferring, but it does nothing to eliminate charges on the tools themselves. Similarly, using tools without precautions significantly increases the risk of ESD damage. Storing tools in a non-conductive container can protect them from external static sources but does not equate to ensuring they are grounded and safe for immediate use. Proper grounding is the most crucial step in creating a safe working environment when dealing with sensitive electronic devices.
