Lighting and noise level in the central facilities of the Costa Rican Distance Education University: health implications for staff and students
Artículo académico
Physical agents of the workplace such as noise and light affect work performance, productivity and quality. Noise can cause insomnia, mood changes, hearing loss and, in pregnant women, fetal damage, and it can promote the development of cardiovascular disease. Poor lighting generates tear production, eye strain and headaches, and increases accident rate. From June 08 through October 23, 2009 we used digital devices to measure noise and lighting in several rooms of the Costa Rican Distance Education University. The rooms were selected because they have noisy machinery or require a particular degree of illumination (printing facilites, warehouse and library). We found that both light levels and noise are inadequate in these departments where a quiet and well-lighted environment is basic to the daily activity and health of staff and students. We recommend the installation of noise dampers, the mandatory use of ear protectors and a redesign of artificial lighting in those specific rooms of the institution.
