Approaching One-year Anniversary of OSHA Silica Dust Rule: Are You Complying?

WASHINGTON, D.C. - Last September 23, the OSHA silica dust rule went into effect. This regulation is designed to protect workers from exposure to excessive levels of airborne silica dust that comes from cutting, drilling, sanding or grinding concrete pavers, bricks, stone or other materials containing crystalline silica.

Health Effects of Silica Dust

The health effects of prolonged exposure to silica dust are severe and include silicosis, an incurable lung disease that can lead to disability and death; lung cancer; chronic obstructive pulmonary disease (COPD); and kidney disease.

Be Ready for OSHA

If you haven’t yet been visited by OSHA, review this article and be sure that you comply to avoid fines and protect your workers’ health.

Choice of Two Methods for Complying

OSHA gives employers the choice of one of two methods of complying with the standard in a construction setting by either using an “engineering method” or by monitoring actual worker exposure. For landscape contractors, using the engineering method will provide the most practical approach to controlling silica dust on the worksite and following the silica regulation.  

Most landscape contractors will be familiar with the engineering control methods, since many contractors were using them, even before the OSHA silica rules went into place. They typically will involve using wet methods to cut, drill or grind silica containing materials or using a vacuum system to remove silica dust at the point it is created.

Engineering Method Based on Task and Equipment

OSHA applies the standard according to the specific task and equipment being used. For each task, there is a specific engineering control method recommended for that piece of equipment. Table 1 is the OSHA reference for each task and control method and can be accessed on this page of the regulations (scroll down).

In addition, OSHA has created helpful fact sheets outlining the specific control measures required for each task in an easily printable form. Some of the more common tasks and equipment used by landscape contractors are listed below and are linked to the pamphlet for that task.

§  Handheld Power Saws Fact Sheet

§  Handheld Grinders for Tasks Other Than Mortar Removal Fact Sheet

§  Jackhammers or Handheld Powered Chipping Tools Fact Sheet

§  Handheld and Stand-Mounted Drills Fact Sheet

§  Stationary Masonry Saws Fact Sheet

Other Silica Rule Requirements

In addition to the compliance measures outlined above, the rule requires several other measures of employers.

§  Each employer must develop and maintain a written exposure control plan;

§  Employers must offer medical surveillance to employees who must wear a respirator for more thirty days or more per year under the rule.

§  Employers must train and inform employees covered by the silica standard about respirable crystalline silica hazards and the methods the employer uses to limit their exposures to those hazards.

§  Employers are required to make and keep accurate records of air monitoring data and objective data used to assess employee exposures to respirable crystalline silica under the standard, as well as records of medical surveillance provided under the standard.

Helpful Booklet

OSHA has published a booklet for employers that helps explain the requirements of the silica rule that is easier to read than the regulations themselves. You may download it by clicking here
