A technician once told me: "I've been using the same insulated screwdriver for 3 years. It's fine."
He hadn't inspected it once.
That's the reality on most job sites insulated tools are trusted blindly, until something goes wrong.
Here's the truth: Insulated tools rated up to 1000V AC / 1500V DC are your first line of defence against electrical shock. But only if you're using them correctly.
3 things most technicians get wrong:
Skipping pre-use inspection a micro-crack you can't see can still cost you your life
Using tools beyond their rated voltage or for unintended purposes
Assuming a colleague already checked the tool always inspect it yourself
We've put together a complete Do's and Don'ts guide for working with insulated tools straightforward, practical, and built for the field.
