Throughout the presentation, the experts emphasized that using water to control dust is the primary engineering control for mitigating silica exposure and a top priority for inspectors. They detailed the importance of proper housekeeping, such as washing down surfaces and avoiding the use of compressed air for cleaning, a practice restricted in California.

The presenters highlighted the resources available to business owners through the NSI, including a free customizable silica exposure control plan on the organization's website that provides a high-level overview of a complete safety program.

The discussion also covered the critical requirements for respiratory protection. The speakers noted a shift toward Powered Air-Purifying Respirators (PAPRs) and reviewed the mandatory medical evaluations, chest X-rays and fit testing required for employees.

The session also detailed the Hazard Communication standard, stressing the need for proper labeling of all containers, maintaining Safety Data Sheets (SDS) and training employees on the chemicals they handle. To underscore the human element of workplace safety, the presenters shared personal stories of how occupational hazards have impacted their health and families, explaining their passion for the subject.
