What is one of the last steps during an onsite inspection process?

During an onsite inspection process, developing a sampling scheme, sampling, and analyzing the materials is considered one of the last steps because it involves confirming the initial observations made throughout the inspection. After completing the initial walkthrough inspection and assessing various elements like HVAC systems and non-suspect materials, the inspector needs to gather concrete data to determine the presence and extent of asbestos.

This step is critical as it allows for a comprehensive assessment based on evidence rather than solely on visual assessments or historical knowledge. By sampling and analyzing materials that may contain asbestos, the inspector can provide accurate information that informs further actions, such as management, remediation, or further monitoring of the site. Hence, this step concludes the onsite inspection process by providing definitive results that have significant implications for health and safety regulations and procedures.
