Ketone comes under which category of prohibited items?

Ketones, such as acetone or methyl ethyl ketone (MEK), are classified as Dangerous substances in the context of aviation security and transport regulations (e.g., Bureau of Civil Aviation Security - BCAS). They are prohibited in cabin baggage because they are highly flammable liquids.

Security protocols typically categorize prohibited items into specific groups:

• Weapons: Firearms, knives, etc.
• Explosives: Dynamite, grenades, etc.
• Dangerous Articles: Tools or sharp objects that can cause injury.
• Dangerous Substances: Chemicals, acids, and flammable liquids/gases.

Since ketones are chemical compounds with significant flammable properties, they fall strictly under the Dangerous substance category. They pose a risk to the safety of the aircraft and passengers due to their potential to ignite or react chemically.
