Gas

Wakey wakey, eggs and carbon monoxide poisoning!

Of the eight gases in this mod, only four (50%) are visible.

• Black is CO (carbon monoxide), and can generate naturally in place of air blocks over lava or fire (upon world generation only) between Y=0 and Y=16 or at any height in the Nether, and will also generate when gas fires burn out and when flammable coal catches on fire. It is poisonous, suffocating, and lighter than air. It decays into carbon dioxide (CO₂) over time.
• Orange is a gas fire and is generated when a volatile gas explodes. It sets you on fire (obviously), is lighter than air, and decays into carbon monoxide (CO) over time.
• Yellow is H₂S (hydrogen sulfide). It is poisonous, is heavier than air, and has a volatility of 100. It can generate naturally in place of air blocks over water (upon world generation only) between Y=0 and Y=16 or at any height in the Nether.
• Red is NUKE, and is heavier than air and has a volatility of 1000, making it ten times as explosive as hydrogen sulfide (H₂S). It only spawns when placed by a player in Creative Mode.

All invisible gases in game are heavier than air.

• CO₂ (carbon dioxide) suffocates. It can generate naturally in place of air blocks anywhere in the world (upon world generation only), although above ground it is unlikely to cause any harm with the plentiful amount of oxygen.
• SO₂ (sulfur dioxide) poisons and suffocates. It can generate naturally in place of air blocks over lava or fire (or in somewhat smaller amounts over any other block) (upon world generation only) between Y=0 and Y=16 or at any height in the Nether.
• CH₄ (methane) has a volatility of 15, and can generate when coal ore is mined.
• NO₂ (nitrogen dioxide) is unimplemented, and doesn't have any effects.

Tips

Wearing a respirator will make you immune to poisonous and suffocating gases, and keeps your oxygen level at 99-100% while it is worn. You will need to change the air filters occasionally, though. To do this, simply put the respirator in a crafting window (the 2x2 one in your inventory is fine) with an air filter.

Carrying a Davy lamp in your hotbar (or placing it) will determine what kind of gas is around it.

• If the flame goes out, it is suffocating (so put on a respirator). If the flame goes out, you will need to relight the Davy lamp by placing it in a crafting grid (the 2x2 one in your inventory is fine) with a torch or a flint and steel (but don't relight it in the same place, or it'll go out again).
• If the flame increases in size and turns blue, it is explosive (so don't place torches or lava or start any fires).

In general, if below Y=16 or in the Nether, don't place torches near coal, recently-mined coal, or naturally-generated water, and don't walk in naturally-generated pockets of air, especially over naturally-generated lava or fire.
