What frequency should orientation for all personnel regarding fire safety be maintained?

The correct answer reflects the necessity for flexibility and responsiveness to the dynamic environment of construction sites. Fire safety orientation should be conducted "as needed" to address the constantly changing workforce on construction sites, including new personnel or changes in operations. Daily or bimonthly orientations can be impractical and may not accommodate the influx of new workers or schedule shifts, while an annual orientation may not be timely enough to ensure all staff are adequately prepared for fire safety at any given moment. By opting for an "as needed" approach, it allows for tailored instruction that corresponds with specific circumstances, new hazards introduced by ongoing work, and compliance with safety regulations, ensuring that fire safety knowledge remains current and effective.
