Apaflurane (HFC 227) is gaseous halocarbon commonly used as a gaseous fire suppression agent, it is a CFC-free propellant. Apaflurane is used to replace chlorofluorocarbons (CFCs) in refrigerant and aerosol applications, including medical use in metered-dose inhalers.

Butane is gaseous alkane with four carbon atoms. Normal butane can be used for gasoline blending, as a fuel gas, fragrance extraction solvent, either alone or in a mixture with propane, and as a feedstock for the manufacture of ethylene and butadiene, a key ingredient of synthetic rubber. Butane is known to be a suffocating gas with a narcotic action. Inhalation of butane can cause euphoria, drowsiness, unconsciousness, asphyxia, cardiac arrhythmia, fluctuations in blood pressure and temporary memory loss, when abused directly from a highly pressurized container, and can result in death from asphyxiation and ventricular fibrillation. Abuse is frequent because butane is easily available and its sale is not restricted. Cases of sudden death in teenagers have been increasing since the 1980s , and over the past few years, there have been an increasing number of publications on the subject.

Isobutane was used as a propellant for aerosol cans and foam products. It was studied as a potential substitute candidate for screen non-chlorofluorocarbon (CFC) metered dose inhaler (MDI) propellant.

Propane, an alkane that at standard temperature and pressure is a gas. It has a role as a food propellant. Propane in combination with butane was used for recreational inhalation in adolescents. That use caused to death. The compounds found in tissues and biological fluids were perfectly compatible with those contained in the containers used for the inhalation. The mechanisms of death were assessed in a combination of the direct toxicity of the compound and oxygen replacement.

Vinyl acetate monomer (VAM) is a key intermediate used in the making of a number of polymers and resins for adhesives, coatings, paints. Human data on the acute toxicity of vinyl acetate is not available. Based on the carcinogenic potential of vinyl acetate in the animals, the substance can have a cancer risk for humans. Carcinogenicity is thought to act via a secondary mechanism and the concern may only be relevant above threshold concentrations.

Benzyl chloride, or α-chlorotoluene, is a reactive organochlorine compound that is a widely used chemical building block. Industrially, benzyl chloride is the precursor to benzyl esters which are used as plasticizers, flavorants, and perfumes. Phenylacetic acid, a precursor to pharmaceuticals, is produced from benzyl cyanide, which is generated by treatment of benzyl chloride with sodium cyanide. Quaternary ammonium salts, used as surfactants, are readily formed by alkylation of tertiary amines with benzyl chloride. Benzyl chloride is an alkylating agent with very irritating properties to the skin. Indicative of its high reactivity (relative to alkyl chlorides), benzyl chloride reacts with water in a hydrolysis reaction to form benzyl alcohol and hydrochloric acid. In contact with mucous membranes, hydrolysis produces hydrochloric acid. Thus, benzyl chloride is a lachrymator and has been used in chemical warfare.
