Biomutant allows you to explore a post-apocalyptic open world where different harmful elements can kill you. Your objective will be to spend as little time as possible in these areas contaminated by various pollutions, or to equip yourself properly to face them.
When you enter a Biohazard zone for the first time, you will unlock a side quest to get the Biohazard Suit. This is the case for every harmful effect in the game (heat, hypoxia, and so on).
How to get the Biohazard Suit
The main Biohazard zone is in sector 6D, just south of Urfidurf Outpost.
As with every suit in the game, you'll need to find the Pingdish. Once you have found the dish, you will have to align the transmitters in order to get a signal. This signal will allow you to locate the suit.
Turn the dish until the colors match and you'll be able to align the signal that pinpoints the location of the suit. Go to Bangshelter 6D.
When you enter the building, you will find a cabinet with an orange suit. You'll have to kill a few enemies in the staircase beforehand.
This equipment is extremely rare and will greatly improve your percentage of resistance to Biohazard.
