3.0 Types of Packagings

?

? @

3.1 Controlling Packagings

?

Any packaging, such as a receptacle, cartridge or case of an article or device, is designed to retain and be directly in contact with a substance or mixture of substances therein and form an integral part of the article or device and is required in order that the device or article may function correctly when used.

?

Disposable LPG Cylinders

Refillable LPG Cylinders

Aerosol Products

Tear Gases

Pepper Spray

Fireworks

Batteries

?
?
3.2 Protective Packagings

?

Any packaging is prepared to perform both protection and containment functions together with any other necessary components and manners for safe and convenient movement of substances, materials and articles. Taking into account the functions in transport, It should be considered extending the concept to include any transport unit that is really the most protective.
