Silica Standard - Table 1 Compliance
OSHA's silica standard for construction (29 CFR 1926.1153) went into full effect in 2018. The centerpiece is Table 1, which specifies engineering controls for 18 common construction tasks.
Table 1 approach (simplified compliance): If you perform a task listed in Table 1 and use the specified controls, you are presumed to be in compliance with the PEL without air monitoring.
Example: Cutting concrete with a handheld saw - Table 1 requires:
- Saw equipped with an integrated water delivery system
- Operate and maintain per manufacturer instructions
- Worker wears APF 10 respirator
Alternative approach: If you cannot use Table 1, you must conduct air monitoring, implement controls to achieve the PEL, and provide medical surveillance.
Table 1 - Selected Common Tasks
| Task | Engineering Control | Respirator |
|---|---|---|
| Handheld power saw - dry cut | Integrated water delivery system | APF 10 |
| Handheld power saw - wet cut | Integrated water delivery AND vacuum | APF 10 |
| Walk-behind saw - dry cut | Integrated water delivery system | APF 10 |
| Angle grinder | Vacuum shroud | APF 10 |
| Jackhammering concrete | Vacuum shroud or water | APF 10 |
| Rotary hammer drilling | Vacuum shroud | APF 10 |
Alternative compliance path: When Table 1 cannot be followed (unusual task, different equipment), the employer must conduct air monitoring within 30 days of commencing work, implement engineering controls to achieve the PEL, and provide medical surveillance for workers exposed above the action level for 30 or more days per year.
Table 1 provides a simplified compliance path for 18 common tasks. Follow the specified controls and you are presumed compliant without air monitoring. The silica PEL is 50 micrograms per cubic meter (8-hour TWA) with an action level of 25 micrograms. Medical surveillance is required at 30 or more days of exposure above the action level per year.
