Summary In the last decades, it was proved that working in the operating rooms (OR) environment has health hazards on the working personnel. The hazards are due to pollution of OR by various pollutants. The aim of the essay is to through light on pollution of the operating rooms from all its aspects as types, sources of various pollutants, their hazardous effects and the recommended safety measures to avoid or at least decrease the incidence of these hazardous effects. The types of OR pollutants are classified into anesthetic pollutants, physical pollutants (X-ray radiation, laser and noise), chemical pollutants skin-cleaning fluids and aerosol sprays) and biogenic pollutants bacterial, fungal and viral). The sources of anesthetic pollutants are: (1) Errors of anesthetic technique as; spillage during filling of anesthesia vaporizer, turning gas flow on before placing mask on the patient, insuffiations of anesthetic agents across child face during induction of anesthesia, un-cuffed or leaking tracheal tubes or poor-fitting laryngeal mask airways, failure to turn off gas flow control valves at the end of an anesthetic, flushing of the circuit, pediatric circuits (e.g., Jackson-Rees), side stream sampling carbon dioxide and anesthetic gas analyzers and equipment failure or lack of understanding the equipment can cause operating room contamination. 2 Leak from various sites of anesthesia machine delivery system as high-pressure hoses or connectors, N20 cylinder mounting, 0 rings.Cfj, absorbent canisters, from low-pressure circuit as improperly connected or leaking tubing, improperly sealed valve domes, deformed gas delivery lines or machine connection joints, leaking delivery lines, leaking Y- connector joints, side stream gas analyzer sampling vented into room and leak from scavenging system as occlusion of disposal system and maladjustment of hospital disposal system vacuum. (3) Other sources as leak ofN20 from cry probe, leak of volatile inhalational anesthetics from - 78-
