OHSA and CSA Z462 emphasize de-energization, lockout/tagout, and PPE precisely because live contact is the greatest risk. On the exam, candidates must be able to identify and prioritize hazards based on severity and likelihood.

A purchase order (PO) is a legally binding document issued by the buyer to request goods or services from a supplier. It specifies quantities, prices, and delivery terms.
