![]() ![]() These are management decisions on work activities, work rotation and work load to reduce workers’ exposure to high noise levels. Examples of engineering controls are: substituting existing equipment with quieter equipment retro-fitting existing equipment with damping materials, mufflers, or enclosures erecting barriers and maintenance. Only, when these controls are proven unfeasible, earplugs as a permanent solution should be considered.Įngineering controls modify the equipment or the work area to make it quieter. ![]() However, as a rule, engineering and administrative controls should always be the preferred method of reducing noise levels on worksites. Laborers Health and Safety Fund of North America says normally, earplugs and other types of personal protective equipment (PPE) are used to control a worker’s exposure to noisy equipment and work areas. High noise levels on construction worksites can be lowered by using commonly accepted engineering and administrative controls. ![]()
