The 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.
