Before each use, Cal/OSHA requires hand tools and portable power tools on a construction site to be:

Explanation

The rule is a before-use duty carried by the person about to pick the tool up: hand and power tools must be inspected before use, kept in good repair, used only for the purpose they were designed for, and taken out of service when found unsafe. Its whole value is that it happens on the day and at the point of use, and that is what each wrong answer gives away. A monthly competent-person inspection (b) catches nothing about the cord crushed this morning. An annual test by the rental supplier (c) certifies the tool as it left the yard. And a weekly inspection with a register (d) is better paperwork and still leaves six days in which a guard can be removed or a cord cut.
