Surface prep generates silica whenever the substrate is concrete or stone. The crew owns the exposure control plan; this post covers the equipment layer.
Engineering controls first: wet methods where compatible, dust-shrouded tools wherever possible, and HEPA vacuuming continuously alongside the work.
Equipment sizing: medium HEPA vacuum for typical scopes; large continuous-bag unit for warehouse-scale floors and extended shifts.
PPE: respirators rated for crystalline silica, regardless of engineering controls in use.
Verification: silica monitoring per your written exposure control plan. Equipment alone does not provide compliance.
HEPA and H-Class vacuums can support dust-control and cleanup practices when used as part of a compliant worksite safety plan. HireAVac does not guarantee OSHA, EPA, or ICRA compliance — your worksite plan, PPE, containment, and procedures determine compliance.
