Extra info: Ultra-Capacitors in the CRS

News from Moditech Rescue Solutions BV

Ultra-capacitors are used in the start-stop systems of various vehicles. The ultra-capacitor is designed to maintain normal vehicle functions, such as lighting, heating/cooling, etc. when the vehicle engine shuts down, and can be found in various locations within in the vehicle. The solvent in the capacitor, Acetonitrile, can pose a health risk for traffic victims and first responders. Further information about this has therefore been included in the Crash Recovery System.  

This month we would like to take the opportunity to introduce you to our skilled team of instructors who are working throughout the Netherlands on behalf of Moditech. Among them are several English-speaking trainers to assist with international training schools in the future.

More on these subjects in our newsletter!


Since the advent of start-stop systems, Moditech has have included information about the presence of ultra-capacitors in the Crash Recovery System. In the latest database update, we have expanded this information with an explanation about the presence of the substance: Acetonitrile. Acetonitrile is a liquid that is found in the capacitor under minor pressure. If the capacitor is damaged, the liquid may spray out.

This is where the danger lies. Traffic accident victims could have inhaled it. There is also an exposure risk to rescue workers if they themselves damage the capacitor while working, should they come in contact with the fluid. 

The toxicological qualities of Acetonitrile are:

  • Acetonitrile liquid or vapour is a highly irritating substance which irritates the skin, eyes and respiratory canal.

  • In high doses, it can result in death due to breathing difficulties.

  • Inhalation of Acetonitrile causes it to be transformed into hydrogen cyanide and thiocyanate in the body (metabolisation), which leads to serious health risks for humans.

A lower dose can lead to symptoms similar to those of cyanide poisoning, such as drooling and nausea. However, this can also occur at a later time.

If the traffic victim has been in contact with acetonitrile, cyanide poisoning may occur in their body. Consequently, it can be difficult to anaesthetize the victim and/or keep him/her anaesthetized. 

If it is suspected that the ultra-capacitor is damaged, the paramedics and/or trauma physician must be informed.  This information can be of vital importance!

To ensure you have the new information about acetonitrile at your disposal, make sure your Crash Recovery System has been updated with the latest database update of 24.08.2017!
