Which statement accurately defines the monitoring rhythm for atmospheric conditions during hazmat response?

Monitoring atmospheric conditions during a hazmat response must be ongoing and responsive to the situation. Hazards can change quickly as products vent, weather shifts, or operations like ventilation and containment are performed. The safest and most effective approach is continuous monitoring or monitoring at intervals required by procedures, with actions and measurements updated as the scene evolves. This real-time or evolving data informs entry decisions, PPE choices, ventilation needs, evacuation or exclusion zones, and overall scene safety. Checking only at arrival misses later changes, and waiting until the scene is cleared is too late to protect responders.
