CFA has a program to retrofit crew protection systems to pre-2005 tankers.
CFA has produced a booklet describing the systems and how to use them.
There are no dates currently provided to update our tankers and it's not likely they will be done for this fire season.
However, you may find yourself on a composite crew on a tanker that does have this new system.
We urge you to read the linked documentation to familiarise yourself with the system and how it works.
