Which of the following are considered post response procedures?

Post response procedures are actions taken after the immediate response to a hazardous material incident is completed. Wreckage removal is a critical post-response procedure as it involves making the area safe, removing any debris that could pose further hazards, and ensuring that the site is cleared for future use or investigation. This step is vital not only for safety reasons but also for environmental protection and restoration efforts.

While training first responders, cleaning windows, and preparing a report are important activities within the broader context of managing hazardous materials incidents, they do not fit the definition of post-response procedures as directly as wreckage removal does. Training is typically a pre-incident or ongoing process, cleaning windows is usually not a priority in the context of hazardous materials incidents, and although preparing reports is essential for documentation and learning, it occurs after the initial response has stabilized the situation but may not involve immediate safety concerns in the same way that wreckage removal does.
