Virginia Abrasives Reference to OSHA Respirable Crystalline Silica Standards
October, 2017


In March of 2016, the Occupational Safety and Health Administration (OSHA) issued a final ruling on respirable crystalline silica dust. This ruling provided for more stringent standards for an employee’s exposure to silica dust. OSHA created two standards: one for construction and one for general industry and maritime.

OSHA began enforcing the new standards in September of 2017.


Virginia Abrasives Corporation (VAC) sells a variety of construction equipment and related accessory products to the construction industry. These products can be used when cutting, grinding, sawing, drilling sanding or polishing concrete, which can generate dust and particulates which may be harmful if inhaled. The new OSHA standard requires employers to limit worker exposure to respirable crystalline silica and to take other steps to protect workers. Employers have two options:


1. Use a control method detailed in “Table 1” of the construction standard, or
2. Measure workers’ exposure to silica and independently decide which dust controls work best to limit exposures


The new OSHA standard states that applicable construction employers are required to do the following:
1. Establish and implement a written exposure control plan. A sample plan can be found on page 46 of OSHA’s Small Entity Compliance Guide for the Respirable Crystalline Silica Standard for Construction by clicking here: OSHA Standard

2. Designate a competent person to implement the exposure control plan
3. Restrict housekeeping practices that expose workers to silica
4. Offer medical exams every three years for workers required by the standard to wear a respirator for 30 or more days per year
5. Train workers on operations that result in silica exposure and ways to limit exposure
6. Keep records of workers silica exposure and medical exams


What is “Table 1”?


Table 1 of the new standard outlines various dust control methods associated with common construction tasks. Table 1 is perhaps the easiest method for contractors to comply with the new standard, particularly if they properly maintain and use equipment as directed by the manufacturer.
