Silica Exposure Control: The OSHA Rule That Changed How Every Dust-Producing Trade Operates

OSHA's respirable crystalline silica rule (29 CFR 1926.1153) substantially tightened silica exposure limits and required engineering controls on construction. Table 1 lists specific tasks with required controls — wet saws, HEPA vacuums, local exhaust. Non-Table 1 work requires exposure assessment and respirator program. Understanding silica compliance is essential for contractors self-performing concrete, masonry, drilling, or demolition work.
