Answer: Table 1 is a tool provided in the OSHA silica construction standard that lays out specific tasks common to the construction industry and describes ways to control employee exposure to silica. Examples include wet methods and dust collection vacuum attachments.
OSHA’s silica standard for construction applies to all occupational exposures to respirable crystalline silica in construction work, except where employee exposures will remain below the AL of 25 μg/m3, calculated as an 8-hour TWA, under any foreseeable conditions. 29 C.F.R. § 1926.1153(a).
7 Μαρ 2023 · This study provides an evaluation of the effectiveness of silica controls and work practices that are mandated in the OSHA Table 1 and presents the potential impact of background silica dust to personal task-based exposures on construction sites.
KEY POINTS FROM THE NEW SILICA DUST STANDARD. The new standard requires a more stringent “permissible exposure limit”, moving from approximately 250 micrograms per cubic meter of air (250 μg/m3) over an 8 hour day (time weighted average) to 50 μg/m3 over an 8 hour day.
7 Δεκ 2012 · Many construction activities can put workers at risk of breathing silica containing dusts, and there is an important body of literature documenting exposure levels using a task-based strategy.
A compensation fund for workers exposed to silica dust, backed by employers, operators and manufactures, to help provide financial relief to workers (and their families) diagnosed with silica related disease
