When must work be stopped following the issuance of a stop work order?

• A. Immediately
• B. Within 24 hours
• C. Within 3 days
• D. Within 7 days

Answer: (A)

A stop-work order requires an immediate halt of all on-site activities. When such an order is issued, work must stop right away to address safety or regulatory concerns and prevent any escalation of risk. There’s no waiting period or grace time—the directive is binding the moment it’s issued, and continuing work even briefly could worsen hazards or violate the order, with potential penalties or enforcement actions. After receiving the order, crews should stop work, secure the site, and wait for the order to be rescinded or for further instructions before restarting.
