CNI Control Measures

As with all hazardous operations key control measures should be in place to minimise potential incidents: 

Contamination

Contamination with acids, alkalis, reducing agents, oxidising agents, amines and phosphates

  • Can initiate decomposition
  • Can produce large volumes of gas
  • Can lead to vessel failure

Example:

Ammonium sulphate solution – No reaction easily separable

Ammonium per-sulphate – Oxidiser = Reaction = Violent vessel failure

Composition of Blends

  • The amount of CNI in fuel packages varies depending upon the functional requirements of the specific additive package

  • Much of the hazardous properties of these additive compositions come from CNI but the other components cannot be ignored

  • With regard to decomposition, the general rule is to treat anything with > 15% CNI as if it was 100%
