Hazard Protection is a basic exosuit technology.


Hazard protection provides basic environmental shielding. Protection from specific planetary conditions can be increased through installation of Hazard Protection Modules.

These units operate automatically once a hazard condition is met. Protection depletes at a certain rate, visually indicated by one, two or three left-pointing arrows and the potential addition of extreme at the end of the protection bar (shown as < to <<< for drain and "extreme"). Once the protection is depleted the shield will take damage once every 16 seconds on normal mode.

Game Description

The Exosuit's Hazard Protection system continually monitors and stabilises the user's environment.

General reactive protection may be augmented with Environmental Shields, offering increased protection against specific conditions.

The device is charged with sodium-based substances. User is advised that a failure to charge the Hazard Protection system may allow their environment to become incompatible with life.


The lifetime of the unit is based on the environment and severity of the hazard. Especially planets with a multitude of transmutations (Frozen Day/Water/Night) can change their hazard during your stay. Storms are always the worst hazard for their planet type and liquids more dangerous than the air, aside of gaia and scorched worlds. Another important thing is the current Game mode:

Hazard Protection Duration (Minutes:Seconds)
Severity/Source Normal Survival/Permadeath
Hazard Level 1 8:06 2:42
Hazard Level 2 7:58 2:39
Hazard Level 3 7:40 2:33
Hazard Level 4 6:29 2:10
Hazard Level 5 3:33 1:11
Hazard Level 6 2:22 0:47
Hazard Level 7 1:47 0:36
Hazard Level 8 1:38 0:32
Hazard Level 9 0:36 0:12

Actual Hazards do not matter, only planet biome, time, weather.

    • White Frozen (Night)
  • Danger Level 4: White planet liquids. Red planets.
    • White Frozen Water (Day/Night)
    • Non-extreme Toxic Water (Day/Night)

    • Non-Extreme Gaia Storms (Day/Night)
    • White Irradiated Storm (Day/Night)
    • White Scorched Storm (Day/Night)
    • Extreme Scorched (Day)
    • Extreme Toxic (Day/Night)
  • Danger Level 8: Extreme water.
    • Extreme Toxic Waters (Day/Night)
  • Danger Level 9: Extreme storms.
    • Extreme Toxic Storm (Day/Night)
    • Extreme Scorched Storm (Day/Night)

Underwater durations refer specifically to toxic/radiation protection drains while underwater on Toxic and Irradiated planets. Not to be confused with Aeration Membrane oxygen drain while underwater. <-- Normally Hazard 2-3. It is not constant!

The remaining protection time can be estimated using the information provided in the lower-left region of the Analysis Visor's overlay. If time runs out while the environmental hazard is still present, the player will begin to take damage periodically until they reach shelter or recharge their protection.

If there are several hazards happening at the same time (e.g. getting irradiated by a Crashed Freighter's cargo container while on a Scorched planet), protection for each hazard depletes at its own rate.

Hazardous Flora

Don't Breathe!
Despite the depiction of toxicity, Underground Toxic Hazard is absolutely lethal. Do NOT engage it and destroy it as soon as possible. Its toxicity is so high, that it penetrates a fully charged S-class protection unit and repeatedly damages the life bar. It can reach over 200 Tox and nothing stops it!

Hazardous Material

Background Radiation Cargo Pod.jpg
Cargo Pod Radiation
Even though extreme Alpha-storms and Supercells can reach up to 32 Rad and be diffused by a radiation module for the entirety of its lifetime, the smaller 22 Rad background radiation of the cargo pods on crashed freighters can not. A hazard module will absorb all drain of the hazard module, but just like the toxic flora it will still penetrate all your protection and hurt you in intervals directly. You are never fully protected against cargo pod radiation!


Charge equipment with Sodium (2.5%/unit), Sodium Nitrate (~6.5%/unit), Salty Custard (50%/unit), Monstrous Custard (50%/unit), Stellar Custard (50%/unit), or Ion Battery (100%/unit).

Environmental Hazard condition

The Hazard Protection starts working when:

  • The temperature exceeds 50°C
  • The temperature drops below -20°C
  • The Toxicity level exceeds 40 Tox
  • The Radiation level exceeds 4 Rad

The Aeration Membrane, which uses similar interface elements to Hazard Protection, starts working when the player has been swimming for more than 5 seconds (see the main Exosuit page for more information).


Hazard Protection is pre-installed on the player's exosuit.

Hazard Protection can be repaired using the following ingredients:

Hazard Protection cannot be dismantled.

Despite being impossible to craft, a placeholder blueprint exists in the Space Anomaly with a suggested build cost of 100 Ferrite Dust.
