What is a key factor in the safe operation of electrical tools?

Ensuring tools are suitable for the environmental conditions is a key factor in the safe operation of electrical tools because different environments can present unique hazards that affect tool performance and user safety. For example, tools used in wet conditions need to be designed to prevent electrical shock, while tools used in hazardous locations might require additional protective features to prevent ignition of flammable substances. Selecting tools appropriate for the specific environment helps mitigate risks and enhances the safety of the operator and bystanders.

In contrast, using tools without certifications may expose the user to safety violations and increased risks, relying on older tools could compromise functionality and safety due to wear and tear, and selecting tools based solely on wattage does not guarantee safety, as the design and suitability for the specific application are more critical factors.
