1.4S

Division 1.4 Substances and articles which present only a slight risk of explosion in the event

of ignition or initiation during carriage. The effects are largely confined to the

package and no projection of fragments of appreciable size or range is to be

expected. An external fire shall not cause virtually instantaneous explosion of

almost the entire contents of the package.

 

S Substance or article so packed or designed that any hazardous effects arising from accidental

functioning are confined within the package unless the package has been degraded by fire, in

which case all blast or projection effects are limited to the extent that they do not significantly

hinder or prevent fire-fighting or other emergency response efforts in the immediate vicinity of

the package.
