Just a quick and dirty reference for various toxins from the Refinery.
tl;dr - have a pen of Condensed Stabilozine if you do chemical warfare, CBRN suits protect from some things but not others, throwable gas is always safe for CBRN suits

- Chemical Skin Irritation/Preso Latex Petrification
If you don't store your Preso Latex in containment toolboxes, or have an accident with your latex tree, you get this.
How to cure: Stabilozine or Condensed Stabilozine

- Wasting Disease
Extremely slow to work, will take several minutes to develop. Early symptoms are slightly blurred vision, whispers, ear ringing. Develops to psychosis, blood vomiting, and eventually paralysis.
How to cure: only with Wasting Disease Antidote. One syringe is not enough - it can go up to 300, and one syringe heals ~40, so you need at least 5-7 syringes applied gradually to completely cure a bad case. Fortunately, the only damage (other than itself) it causes is blood vomiting, so if you have no antidote, you can technically keep someone alive almost forever if you have enough saline, and get to an outpost doctor.

- Lineavirus
Slow to work, causes coughing, audial hallucinations, and infects everyone within a couple meters of the carrier. CBRN SUITS DO NOT STOP IT DESPITE THE DESCRIPTION (bug?). DO NOT APPROACH INFECTED PEOPLE. Eventually develops to rapid vomiting, green screen, and makes skin green.
How to cure: Lineavirus Antidote (in medical fabricator, not refinery). One syringe is enough, but you will almost definitely get infected when applying it to someone, and it spreads, so multiple might be needed, as well as a smart quarantine to stop the spread.

- Refined Ignis Latex
Great ammo for syringe guns, turns them into functional firearms. 3-4 syringes will kill a man with organ damage. CBRN SUITS DO NOT STOP IT.
How to cure: it gives you various injuries, but mostly organ damage, so morphine.

- Volatile Preso Latex Canister
You can smash this over someone's head to give them a lethal dose of Preso Latex Petrification over time. Causes organ damage and irritation in an area if not contained.
How to cure: Stabilozine/Condensed Stabilozine

- Devil's Blood Grenade (throwable)
Makes a Devil's Blood gas cloud and a small explosion. Affects targets with increasing bleeding and blood vomiting, eventually killing them. CBRN suits will block the gas, making it safe to use even if you drop it on the floor.
How to cure: Condensed Stabilozine will cure the Devil's Blood toxicosis, after that you just need to heal the organ damage, bleeding, and blood loss until the patient is stable.

- 40mm/RPG Devil's Blood Grenade
PENETRATES CBRN SUITS. Same as above, but a lot more dangerous to use at close range or if you mess up your aim.

- 12 Gauge Devil's Blood Slugs
Individual slugs don't have enough potency to inflict Devil's Blood on targets. You will need AT LEAST 2 good hits on a target to give them Devil's Blood toxicosis, but even then they will take some time to die from it. CBRN suits are immune to the gas that shells leave, but NOT TO BEING SHOT by these.

- Devil's Blood Railgun Shell
PENETRATES CBRN SUITS (and your entire body probably). Because most fauna nowadays is immune to bleeding (and some are immune to poison), this is a poor tool to use against creatures - one shell isn't enough to kill even a hammerhead. It's best used against human targets such as pirates or outposts. It will afflict things through walls, but the range is relatively small, so you need to aim directly for areas with people.

- Preso Latex Grenade (all types)
Causes a small explosion and splatters Preso Latex everywhere, causing petrification, rapid vomiting, and blood vomiting. CBRN suits are immune to all types, making this one of the safest chemical weapons to use.
How to cure: Condensed Stabilozine, and something for the bleeding/organ damage.

- Hexa-nova Grenade
Almost instantly lethal, causes heavy bleeding, organ damage, and blood vomiting. CBRN suits are immune to the gas, making this the most lethal gas grenade you can get.
How to cure: Patients that managed to get a low dose of the gas (far from the cloud) can survive for some time, in which case Condensed Stabilozine to cure the toxicosis, and something for the bleeding.

- 40mm Hexa-nova Grenade
PENETRATES CBRN SUITS. If you shoot it next to yourself you are basically dead unless you can Condensed Stabilozine yourself in time while vomiting.
