Suitable securing means shall be used as described in the CTU Code Page 456, Paragraph 18.104.22.168 states that suitable means capable of restraining the goods shall be used to secure dangerous goods.
22.214.171.124 Packages containing dangerous goods and unpackaged dangerous articles shall be secured by suitable means capable of restraining the goods (such as fastening straps, sliding slat boards, adjustable brackets) in the cargo transport unit in a manner that will prevent any movement during transport which would change the orientation of the packages or cause them to be damaged.
When dangerous goods are transported with other goods (eg. heavy machinery or crates), all goods shall be securely fixed or packed in the cargo transport units so as to prevent the release of dangerous goods. Movement of packages may also be prevented by filling any voids by the use of dunnage bags or by blocking and bracing.
Where restraints such as banding or straps are used, these shall not be over-tightened to cause damage or deformation of the package or the securing points (such as D-rings) within the cargo transport unit. The packages shall be packed in such a way that there will be a minimum likelihood of damage to fittings during transport. Such fittings on packages shall be adequately protected.
Where restraints such as banding or straps with integral container fittings are used care should be taken to ensure that the Maximum Securing Loads (MSL) of the fittings is not exceeded.
