In Oxygen Not Included there are a lot of substances and materials that are used to keep your Duplicants alive that can also kill them if not properly co🔜ntained or used appropriately. One such substance that has plagued many players is chlorine.
Chlorine, both in the game and in real life, is a toxic gas that, if not properly contained, has many harmful effects, number ღone being death. Fortunately, there are a number of ways it can improve the lives of your duplicants, and it can be an effective tool to keep their little hearts beating just a little longer—you just have to know how to use it.
Updated February 17th, 2021 by Ben Baker: Thanks to recent updates to the game there are new ways to obtain and use Chlorine. It’s not a game changing substance, but with more uses it offers pla🐠yers other alternatives than simply dumping it into space and wasting it. If you haven’t been using Chlorine these new potential uses ജmay change your mind.
15 Hꦰow It’s Obtained 🐈
There are three main ways to obtain chlorine other than finding random pockets of it; chlorine gas vents, bleach stone, and Rust Deoxidizers. The gas vents will pump out chlorine continuously, and bleach stone will emit chlorine after it’s been mined. For a renewable source of chlorine, you obviously want to seek꧂ out the Gas Vents, which will always appear in caustic biomes.
ꦬIt’s important to note that bleach stone is h♐ighly unstable, and, if not properly contained, will convert to chlorine which may or may not be useful for you. To prevent this conversion, stick it in an area filled with carbon dioxide or any liquid.
When the Rust Deoxidizer is📖 used it produces Oxygen, Iron Ore, and Chlorine. The Chlorine is largely a byproduct as it only produces 30 grams of it a second. Still for players using Rust Deoxidizers to clean out Rust Biomes it’s another source of this handy gas.
14 It Floats In The Middle 🍃
As mentioned before, chlorine is a toxic gas. It’s heavier than oxygen, but it’s lighter than carbon dioxide, whi💜ch means this substance will float between the two in any given space. This is really important to remember when you're trying to store it.
It’s also important to remember if you just need to get rid of it. Many players, especially in the beginning, will have a large cavernous space below their base to trap carbon dioxide and wꦓater un💟til they can use it more effectively later. If the space is large enough, you can trap chlorine too, but additional carbon dioxide will float it upward so keep that in mind.
13 In A L𒀰iquid State
Chlorine, if cooled below -34.6 °C, will turn into a liquid state, which can be useful for transporting chlorine safely to other areas of your base or can be used as a very effective coolant. It’s also the only way to irrigate Gas Grass, which is used with Gassy Moos in natural ga🧸s farms.
To obtain liquid chlorine, you can either find it naturally in the Frozen Biome or produce it yourself by using a Thermo Regulator. Keep in mind t𒉰hat, once it reaches a temperature above -34.6 °C, it will turn back into a gas.
12 ꧑ Disinfect Rooms ౠ
The main use of chlorine is to act as a disinfectant. It’s the single best way to clear a room full of germs quickly after it has been contaminated. You can transport chlorine via a gas pump pa⛎ired with a gas filter and send it through gas piping to the de༺sired location.
Alternatively, you could transport it in its liquid state and then heat it until it turns into a gas, or you could place ꦺbleach stone in the area you wish to disinfect and wait for it to convert to chlorine. It takes a full cycle to disinfect any given room.
11 🐠 Disinfect Duplicants
Chlorine can also be an effective way to prevent duplicants from spreading diseases. Similar to an airlock or sterilization corridor, for quarantine purposes you can create a room filled with chlorine gas to function the same way. It has to be in a room with an airlock or a water airlock to prevent chlorine from lea🍌king to other parts of your base.
Once set up, you’ll simply have Duplicants walk through the room to disinfect all surface germs o🦄n their body. Be sure to keep them moving through the area, as chlorine is unbreathable,꧃ and they will die if they stay too long.
10 ♊ Disinfect Water 🍰
Chlorine can also be used to disinfect water by pumping it to your water sto💖rage and letting it hover above the surface of the water. After a full cycle, the entire supply of water will be sterilized, and you can pump out the chlorine with no ill effects or pollution of the water.
9 Preꦑvent Spoilage
Chlorine can also be used to keep your food fresh and clean indefinitely. If food is stored in a room full of chlorine, it will never obtain the germs that cause food spoilage. Contrary to popular belief, there will be no negative side e🍸ffects from storing food in a chlorine-filled room.
8 Combat Slimelung ꦡ 🐭
Slimelung is perhaps the most stubborn germ that has killed many duplicants through various playthroughs. Fortunately for players, chlorine can be used to combat Slimelung. To do tꦡhis, either fill a slime room with 💧chlorine and prevent the germ from ever occurring or bathe your infected items in a room filled with chlorine.
Like food, the items can be st♏ored there indefinitely and never become infected. It wonܫ't cure a Duplicant that’s already diseased, but it can be a great way to prevent them from becoming contaminated.
7 🃏 Fuel For Ore Scrubbers
Chlorine acts as a fuel for Ore Scrubber machines that will use the gas to kill germs found on raw ores and can also be used to disinfect water bottles. It’s yet another great way chlorine can be u๊sed to ensure your base is germ-free and keep your duplicants safe.
6 🍨 Balm Lily Farm
Balm Lily are useful plants that can be ꦚu🍸sed to produce balm lily flowers which are used in creating Medicine Packs. Alternatively, the plant itself serves as food for Dreckos, which are useful for producing a number of different resources.
While most plants will die in a chlorine-filled en𝓰vironment, balm lily actually requires a chlorine atmosphere ♉to grow. Given how useful balm lilies are, it’s highly recommended to secure chlorine to create a garden.
