![]() Third, the general industry standard does not apply to silica exposures that result from the processing of sorptive clays. Second, the general industry standard does not apply to agricultural operations covered under 29 C.F.R. § 1910.12(b) occupational exposures to silica in construction are covered under 29 C.F.R. First, the general industry standard does not apply to construction work as defined in 29 C.F.R. OSHA's silica standard for general industry applies to all occupational exposures to respirable crystalline silica, with the following exceptions. TWA – time-weighted average Scope and Application (29 C.F.R. PLHCP – physician or other licensed health care professional ![]() PEL – permissible exposure limit (50 μg/m 3 as an 8-hour time-weighted average) HEPA filter – high-efficiency particulate air filter The following acronyms are used throughout this document:ĪL – action level (25 μg/m 3 as an 8-hour time-weighted average) A short introductory paragraph is included for each group of questions and answers to provide background information about the underlying regulatory requirements. These FAQs provide guidance to employers and employees regarding the standard's requirements. OSHA developed these Frequently Asked Questions (FAQs) about the standard in consultation with industry and union stakeholders. On March 25, 2016, the Occupational Safety and Health Administration (OSHA) published a final rule regulating occupational exposure to respirable crystalline silica (silica) in general industry (the standard). Frequently Asked Questions for General Industry In addition, the Act's General Duty Clause, Section 5(a)(1), requires employers to provide their employees with a workplace free from recognized hazards likely to cause death or serious physical harm. Pursuant to the OSH Act, employers must comply with safety and health standards and regulations issued and enforced either by OSHA or by an OSHA-approved State Plan. It is not a standard or regulation, and it neither creates new legal obligations nor alters existing obligations created by OSHA standards or the Occupational Safety and Health Act. ![]() Roof safety mesh is a must-have for any mining business owner.This document is advisory in nature and informational in content.

The dust monitor system from Nome Services can help you keep track of the dust levels in your area and take steps to reduce them. Use engineered controls for dust suppression Using local exhaust ventilation (LEV), which removes dust at its point of origin so that it doesn’t enter the air, can be a very effective form of du st suppression, as can dust containment systems which continuously remove and filter the contaminated air. Workwear can be contaminated by silica dust – which, in some cases, is so fine that it can barely be seen – so it should always be washed separately. ![]() Keeping equipment clean in workplaces with high levels of silica Contamination can be a significant cause of concern in these environments. One of the most effective ways of minimizing silica dust exposure is to provide your workers with personal protective equipment (PPE), such as respirators that cover the nose and mouth. ![]() Wear suitable workwear in environments with the risk of silica exposure. Respirable crystalline silica (RCS) – also known as silica dust – can get deep into the lungs when breathed in, which, over time, can lead to lung cancer or other serious respiratory diseases. How to reduce the risk of Silicosis and silica dust exposureĬarrying out everyday construction tasks such as grinding, drilling, and cutting generates dust, which can easily be inhaled if the dust is fine enough. ![]()
