Under Thai regulation for Occupational
Health and Work Environment, illumination in the
office workplace must be at least 400 lux. This
study found that 55.8 % of workstations had lower
light intensities than the minimum standard
requirement. The working conditions of
insufficient lighting and glare are unsafe
conditions for office workers. Moreover,
inappropriate workstations and seat heights as well
as other ergonomic factors are hazardous
conditions which might play a role in the incidence
of musculoskeletal pain. The findings suggest that
office workers and the organization should be
concerned about adverse health effects of
occupational exposures to work environment
hazards and to improve ergonomic workstations
appropriately for each individual worker.
