Ozone Layer Protection Ordinance

Guidance Notes on Substances that are under Control of the Ozone Layer Protection Ordinance

1.

Under Section 2 of the Ordinance, "scheduled substance" -

(a) means a substance listed in the Schedule, whether existing alone or in a mixture; but
   
(b)

in sections 4 and 6 (of the Ordinance) does not include a substance listed in the Schedule that is -

(i) in a manufactured product (other than one used solely for the transportation or storage of the substance) and the substance is used in the operation of the product or the mere dispensing of the contents of the product constitutes the intended use of the substance; or
   
(ii) part of a manufactured produce solely because the substance was used in the process of manufacturing the product.
   
2. The above definition excludes from consideration as a scheduled substance any substance listed in the Schedule, whether alone or in a mixture, which is in a manufactured product other than a container used for transportation or storage.
   
3. If a substance or mixture must first be transferred from a bulk container to another container, vessel or piece of equipment in order to realize its intended use, the first container is in fact utilized only for storage and/or transport, and the substance or mixture so packaged is covered by the definition of scheduled substance.
   
4. If, on the other hand, the mere dispensing of the product from a container constitutes the intended use of the substance, then that container is itself part of a use system and the substance contained in it is therefore excluded from the definition.
   
5.

Examples of use systems to be considered as products are :

(i) an aerosol can;
   
(ii) a refrigerator or refrigerating plant, air conditioner or air conditioning plant, heat pump, etc;
   
(iii) a polyurethane prepolymer or any foam containing, or manufactured with, a controlled substance;
   
(iv) a fire extinguisher (wheeled or hand-operated) or an installed container incorporating a release device (automatic or hand-operated).
   
6. Any amount of a scheduled substance or a mixture of scheduled substances which is not part of a use system containing the substance is a scheduled substance for the purpose of the Ordinance (ie a bulk chemical). Hence, the size of the container or whether the container is rechargeable is immaterial to determine whether the substance is excluded from the definition.
   
7.

Bulk containers for shipment of scheduled substances and mixtures containing scheduled substances to users include but not limit to (numbers being illustrative) :

(i) tanks installed on board ships;
   
(ii) rail tank cars (10-40 tonnes);
   
(iii) road transfers (up to 20 tonnes);
   
(iv) cylinders from 0.4kg to one tonne;
   
(v) drums (5-300kg)
