Recommendations to Protect Workers From Dust Exposure

Wednesday, November 11th, 2009

Dust ExposureNIOSH have developed recommendations to help protect workers from exposure to crystalline silica dust during construction activities.

The following guidelines for controlling hazardous dust when used enclosed cabs for construction activities are based on the aforesaid recommendations.

Conditioning of the work site

  • Develop a health and safety plan specific to the site. The plan must include commitments to recognize conditions that may generate silica dust and plan strategies for dust control or elimination. It should include engineering controls, personal protective equipment and work practices.

Hazardous Dust in Enclosed Cabs Used by Operators

Wednesday, November 11th, 2009

Hazardous Dust in Enclosed CabsThe construction workers operating enclosed cabs may be exposed to hazardous dust containing silica. The National Institute for Occupational Safety and Health (NIOSH) determined that exposure of machine operators can be reduced through modernization of the air pressurization systems and filtering present in the booths, the use of compounds to sweep the floors and implement programs to control dust.

Inhalation of crystalline silica dust can cause silicosis, a deadly lung disease. No effective treatment exists for silicosis, however, can be prevented by controlling the exposure of workers to dust containing crystalline silica. Exposure to crystalline silica has also been linked to lung cancer, kidney disease, decreased lung function and other disorders.

Many construction activities may generate dust crystalline silica polishing or cutting concrete, repairing masonry structures, using jackhammers to break concrete or excavation of mobile (eg., Drills, loaders, graders, dozer, straight blade grader and bridge cranes).

The cabins for the operators of the construction industry are made to protect operators from excessive noise and dust. When the equipment is new, the controls in the cockpit can usually reduce exposure to dust to an acceptable level. However, as the team goes getting old, many components of the control system deteriorates (eg sealing), which may cause the operator is exposed to hazardous levels of dust.

Reduce Exposure to Hazardous Dust in Drilling

Dust in DrillingConditioning of the work site:

  • Develop a health and safety plan specific to the site. The plan must include commitments to recognize conditions that may generate silica dust and to describe the strategies for the control or elimination of dust. Include engineering controls, personal protective equipment and work practices.
  • During the drilling of rock, dust control through control systems dry or wet. Wet systems are efficient but can be frozen in winter. Caution is advised if wet systems are used when electric power sources. When buying equipment, make sure you have systems for dust control. Always use the dust control system and keep it in good condition. Do not use the equipment if the dust control system is not functioning properly.

Hazardous Dust in the Drilling of Rocks During Construction

Tuesday, November 10th, 2009

Hazardous DustWorkers may be exposed to hazardous dust containing crystalline silica when using drilling systems for site preparation. The National Institute for Occupational Safety and Health (NIOSH) determined that dust from drilling can be reduced by using wet or dry engineering controls to reduce dust, enclosed cabs and implementing a program for controlling dust .

Inhalation of crystalline silica dust can cause silicosis, a deadly lung disease. No effective treatment exists for silicosis, however, can be prevented by controlling the exposure of workers to dust containing crystalline silica.

Firing Ranges

Employers and operators of shooting ranges should take the following measures to protect their workers and practitioners draft exposure to concentrations of lead and hazardous noise levels at the firing range covered:

1. Provide workers and practitioners draft hazard information and adequate training to prevent hazardous exposures.

  • Provide general information and specific warnings about the risks through job bulletins and training programs especially aimed at them.
