Did anyone know how to change HAZMAT suit for firefighters or THW crews? I got a hazardous transport accident event, so I alarmed the HAZMAT unit and deployed the decontamination tent, but I didn't find any button for changing the HAZMAT suit. and when I tried to move the victims into the tent, it said "It needs at least two firefighters with HAZMAT suit in the tent first."
Here's the screenshots (The translation was made by myself, just ignore it):
You need to change to scuba gear first. After that, you can select the hazmat-suits.
