Since 1987 taking the danger out of dangerous goods

overpack

  • Everyday thousands of overpackscontaining dangerous goods are offered for all modes of transport. However, are they shipped in compliance with dangerous goods regulations?

    This article intends to provide some helpful guidelines to ship overpacks containing dangerous goods in accordance with dangerous goods regulation requirements.

    Overpack concept and definition

    A common question asked by those involved in dangerous goods shipments is the following:  is an overpack a package? What are the main differences between them?

    An overpack, as defined in the IATA Dangerous Goods Regulations is an enclosure used by a single shipper to contain one or more packages and to form one handling unit for convenience of handling and stowage.

    On the other hand, a packageis defined as: the complete product of the packing operation consisting of the packaging and contents prepared for transport.

    Marking and labelling requirements for overpacks

    Overpacks shall be marked and labelled in accordance with dangerous goods regulations provisions. Generally, an overpack shall reproduce the markings and labels appearing on the package(s) inside the overpack, unless all markings and labels representative of all dangerous goods contained in the overpack are clearly visible.

    If the dimensions of the overpack require it, labels and markings shall be reproduced in two opposing sides of the overpack.

    Depending on the applicable transport regulation (such as: IMO-IMDG Code, ICAO- IATA-DGR ADR or 49-CFR), the required markings and labels can include UN number(s), Proper Shipping Name(s), Orientation Arrows, limited quantities marking, hazard labels (primary and subsidiary if they are required) for each dangerous goods package contained in the overpack and any additional handling information/markings appearing on the package (s).

    In addition to the information mentioned above and an indication of compliance, an overpack shall be marked with the word “overpack” unless markings and labels representative of all dangerous goods contained in the overpack are visible.

     

    Overpacks & Safety

    Dangerous goods overpacked shall ensure safety requirements. The attached list shows some positive reasons to ship dangerous goods overpacked:

    • Facilitate identification of the dangerous goods overpacked
    • Protect the package from damage
    • Avoid any leakage from the package

    However, it is important to ensure that safety practices are implemented with the aim to minimize potential risks and injuries such as:

    • Incompatibilities in the storage of dangerous goods  
    • Product damage related to handling operations (for instance: stabbing which can result from having the forks extended too far out from a load or from the practice of pushing a pallet using the forks )

    Bear in mind that a safe warehouse environment and proper handling practices can be the key to success.

  • The 57th edition of the IATA Dangerous Goods Regulations (DGR) will incorporate the new amendments made by the Dangerous Goods Board. These changes will come into effect as of January 1st 2016. Some of the changes have already been discussed and approved at the IATA Dangerous Goods Board's meetings and are therefore expected to appear on the 57th edition of the DGR; this article will guide you through them.

  •  

    Every day thousands of packages of dangerous goods are transported all over the world by air, road, sea, or rail. Before offering them for transport, shippers must ensure that they have been properly identified, packed, labelled, marked and documented in compliance with international transport regulations such as ICAO TI (IATA DGR), IMO-IMDG, ADR or 49- CFR.

     

    Ensuring labelling and marking provisions is essential in the safe transport of dangerous goods. This article is intended to provide some advises for those engaged in the stages of labelling and marking packages and overpacks containing dangerous goods.

     

    Format: all hazard labels and handling labels must conform in shape format, symbol and text  shown in the regulations. Any other is forbidden.

    1. Dimensions: hazard labels must conform minimum dimensions in accordance with regulations and set an angle of 45 º (diamond shaped)
    • Location: labels should be affixed adjacent to the shipper’s or consignee`s address appearing on the package
    • Visibility: labels and markings must be so placed on the packages or overpacks that they are not covered or obscured by any part of or attachment to the packaging or any other label or marking.
    • Duplication:  remember that for IBC or large packages labels and markings should be placed in two opposite sides
    • Durability:  the material of every label, the printing and any adhesive thereon must be sufficiently durable to withstand normal transport conditions including open weather exposure without a substantial reduction in effectiveness
    • Irrelevant or damaged labelling or marking already on the package or overpack shall be removed or obliterated.
    • Markings for Overpack: unless all markings representative of all dangerous goods in the overpack are clearly visible, the overpack must be marked with the word “overpack” and the required markings and labels appearing on packages inside the overpack.

     

    The application of labelling and marking provisions is responsibility of the shipper. However, DGM can support you providing a fully compliant operations service for all modes of transport and all hazard classes.

     

     

     

     

  • The upcoming new edition of the IATA Dangerous Goods Regulations (DGR) has introduced segregation provisions for certain packages containing lithium batteries. This has been a result of our better understanding of the risks posed by one of the most common dangerous goods that are shipped worldwide. While some of these provisions will come into effect immediately together with the rest of the new provisions on January 1st, 2018, for others a transitional period has been devised.
