There are many different work tasks and workplace hazards related to the ICU setting. The workplace hazards include the physical environment of the ICU, working conditions, psychosocial factors, ergonomic factors, biological factors and chemical factors that cause ICU workers to have health problems. The occurrence of occupational health problems in ICU workers not only leads to decreased job satisfaction and productivity but also increases absenteeism and burnout. Moreover, this situation adversely affects patient care and increases the cost of treatment. Recognising occupational hazards and risks arising from the work environment will assist in planning strategies to protect and promote health programmes for ICU workers. Understanding the importance of occupational health and safety practices by all institutions is a key factor to improve quality of life, work efficiency and work satisfaction of ICU workers.
