X47.9: Accidental poisoning by and exposure to unspecified gases and vapours

Accidental poisoning by and exposure to unspecified gases and vapours refers to an unintentional inhalation of a toxic substance that is gaseous or vaporous in nature. This exposure can occur in various settings such as domestic, occupational or industrial spaces, and often results from improper use or handling of harmful substances. Due to the unspecified nature, the toxic gases and vapours can range extensively. Symptoms usually depend on the type and quantity of the gas inhaled, and can include headaches, dizziness, difficulty in breathing, blurred vision, and sometimes even unconsciousness. The respiratory system is primarily affected but other body systems may also suffer damage depending on the specific gas involved. The onset of symptoms can be immediate or delayed depending on the exposure levels. Severe or prolonged exposure can progress into more serious conditions, even resulting in long-term health issues or death.
