Which of the following is a required permanent marking on dispersed aerosol agent containers?

• A. Type and net weight of aerosol-forming material permanently marked
• B. Date of manufacture
• C. Name of manufacturer
• D. All of the above

Answer: (D)

Dispersed aerosol agent containers must carry markings that stay with the cylinder for identification, traceability, and safety throughout its life. All of these details are required: the type and net weight of the aerosol-forming material so you know exactly what agent is inside and how much is present; the date of manufacture so inspectors can determine remaining service life and scheduling for tests or replacement; and the name of the manufacturer so the source is identifiable for service, maintenance, or replacement parts. Permanent markings ensure the container can be properly identified and handled during inspections, maintenance, and incident response, even after years of use.
