Operation manual for PEHD polythene barrels and cans.

Sotralentz-Packaging advises and helps the customer to choose the appropriate packaging , taking into account the substance, its storage method, internal and external transport, as well as its final application.    the responsibility for the correct selection of a container for a substance is on the part of the customer – user. He is obliged to make sure that a particular substance is fit for a given type of packaging, as well as its closing and gaskets. It is necessary to consult the Sotralentz valve catalogue.    The height of static storage (warehouse) and dynamic storage (transport) depends on the substance density and the type of internal transport used. Product density influences the total weight of a barrel/can. in the case of density of over 1.3 particular care must be taken with the height of storage. If in doubt, please consult Sotralentz company.

1. Storing empty barrels and cans.

It is necessary to avoid storing next to sources of heat (radiators, warm containers, warm sewage pipes) and places exposed to sparking.    Do not store barrels/cans in dirty places.    Avoid longer storage outside a building and direct exposure to UV rays.

2. Filling barrels and cans.

Check that the nozzle and filling devices do not cause damage of the barrel/can, and especially its closures.    Plugs should be turned on with a proper force indicated by the manufacturer. Greater force should not be used.    After filling the inlet cover should be tightly turned.    If it is necessary, use closures with venting (for degassing or aerating).

3. Filling barrels and cans with a warm substance.

Do not pile polythene barrels/cans on one another if they are still warm.    It is possible to reach the temperature of 80° C as a result of filling, but this should not last more than a few hours. In the case this period is longer, the temperature cannot exceed 60° C.    The state of packaging should be checked in the case the temperature of the packaging is raised at the moment of filling. Some chemicals should not be used together with high density polythene at temperatures higher than 25° C.    After being filled with a warm substance, the barrel/can must: • Be open until the content reaches the ambient temperature, • Be equipped with a closure with a degassing system.

4. Storing, internal and external transport of filled PEHD barrels and cans.

Use fork lifts adjusted to barrels/cans. If in doubt, please contact Sotralentz.    Use only palettes in a good condition and with size relevant to the given amount of packaging. Avoid uneven load of palettes. Do not place barrels/cans so that they protrude outside the palette. Always check that the palette does not have any damage, splinters or nails which could make a hole in the packaging.    Store only on an even and properly hardened surface.    In the case the barrels/cans have venting/aerating system, they must be stored in a vertical position.    Make sure that the user has all information about the recommended height of storing barrels/cans.    Barrels/cans of the same kind and volume should be placed on one palette. Never place barrels/ cans of different forms on the same palette.    Always make sure that the security of the packaging on the palette with, e.g., thermo shrinking foil is appropriate and will not cause damage or deformation of barrels/cans by too tight a grip. In the case of medium weight barrels/cans it is recommended that protective corners of cardboard paper or plastic are used.

5. Marking and official certification of dangerous materials.

The ONU (UN) marking certifies the compliance of barrels/cans with the recommendations issued by UNO regarding transport of dangerous substances and RID/ADR regulations, as well as the IMDG code.    The range of official certification (density, type of packaging, pressure) indicated in the UN marking is appropriate for chemical substances which are similar to water. For other standard liquids the range is generally lower. It is necessary to rely on documentation.    Tests concerning the maximum storage height are effective with the recommended palette load and when they allow certain insignificant deformation of the packaging tested. The amount of load given during the tests cannot be used for static storage in practice, not to mention dynamic storage. If in doubt, please consult this issue with us.    The value of hydraulic pressure indicated in the UN marking gives information about the maximum pressure the packaging can endure for 30 minutes. This value should not be relied on when pumping the substance.    The nominal volume of barrels and cans should be assumed to be approximate value.
