ISO 5364:2008 specifies requirements for oropharyngeal airways of plastics materials and/ or rubber, including those with a reinforcement insert made of plastics materials and/ or metal. Flammability of oropharyngeal airways, for example if flammable anaesthetics, electrosurgical units or lasers are used, is a well-recognized hazard. It is addressed by appropriate clinical management, which is outside the scope of this International Standard.
