Chemical Hazards In Hospital Rooms

2.3 Chemical Hazards Indoor sources of chemical pollutants are users, building materials and furnishing, use of disinfection and sterilization substances, cleaning agents and anesthetic gases. Studies by Bilban et al. Cheong and Chong and Dascalaki et al. asserted that chemical pollutants in hospital rooms are closely related to incorrectly designed or poorly maintained ventilation systems. Causes of concerns are also older facilities and other installations. Additionally, contaminant type is related to construction materials, type of ventilation system, and type of procedure (i.e. anesthesia), used products (i.e. sterilization/disinfection) and presents a general characteristic of each hospital, and the specific characteristic of hospital

Landsbergis (1988) found out that who identified that, job strain and stress, physical exertion, hazard exposure among health care workers. He also reported that jobs in hospitals were combined with high level of job demand and excessive work load which produce job strain and stress among health care workers. The present study has also found that pain in back, neck, joints, leg and joints and also stress are the impacts of occupational hazards of medical laboratory technicians.

There were types of physical hazards such as fires and burns from laser beams, noise levels from technical equipment, electrical burns and fires, and ionizing radiation from x-rays, fluoroscopy, image intensifiers, radioactive implants and other therapeutic radiation procedures.

2.4 Needle-stick Incidents

Latex gloves dusted with cornstarch powder are the most often used. The gloves and the mask form an efficient barrier against most pathogens and recently proven, they also constitute a very good barrier against viruses, provided the gloves and the mask are intact. (Kalwa P et. al, 2011) However, they may also be a source of allergies- primarily in those persons who use rubber products on a regular basis. In this respect, dentists are at particularly high risk. It is estimated that 2.8%-17% of the employees in health service are allergic to latex. (Naheeda S M, 2013) Allergy to latex gloves is the most frequently reported cause of dermatitis in dental personnel in various studies around the world.(Peter A. L, et .at 2007) (Katelaris CH,et .al,
