The notified rule establishes the requirements that must be met for valve bag-type sacks used for the manual transport of cement. This applies to sacks of cement of any origin or provenance. This rule does not contain reference to either storage conditions or the lifespan of the cement packed in valve bags as this information must be included on the bags' labelling (see clause 5). This rule does not concern safety issues, if there are any, associated with its use. It is the responsibility of the user of this rule to establish appropriate health and safety practices, and to determine the degree of application of the regulatory limitations prior to use.
