What should be done after collecting each sample?

After collecting each sample, it is essential to clean tools and fill the hole if necessary. This practice ensures that any contamination or potential cross-contamination is minimized by properly sanitizing the equipment used during the sampling process. Cleaning tools prevents the transfer of asbestos fibers or other hazardous materials that may be lingering on the equipment, which is crucial for maintaining the integrity of subsequent samples.

Additionally, addressing any holes created during the sampling is important from a safety and regulatory standpoint, preventing the release of asbestos fibers into the environment. By filling in any holes, you help mitigate further exposure risks and comply with best practices and regulations in handling asbestos materials.

This action is a key part of following proper protocols after sampling, ensuring that both the environment and health standards are upheld following the investigation process.
