Road Flares are part of the starting gear and provide short-duration illumination with a distinct red glow. Each flare burns for approximately 3 minutes before burning out. While lit, the flare continuously releases heat energy into the surrounding atmosphere, and can ignite combustible gas mixtures in the area. They can be painted with Spray Paint to change their glow color.

Usage

Hold secondary use to light a flare while holding it. Lit flares can be thrown by pressing the throw key. A single flare separates from the stack when lit, leaving the remainder in hand.

Flares add heat to the local atmosphere each tick while burning. This makes them useful as a cheap heat source, but caution is required around combustible gas mixtures. If ignition is a concern, consider using a Chem Light instead.

A lit flare placed inside a container with an internal atmosphere (such as a Portable Gas Tank) will heat and potentially ignite the gas stored inside.

Road flares can also be loaded into a Flare Gun as ammunition, in which case the fired flare deploys a parachute and descends slowly to provide overhead illumination.

-[[Road Flare | Road Flares]] are part of the [[Starting Gear| Starting Gear]] and are found scattered around the spawn area. They burn for a short period of time and give out a distinct red glow in a small area. In a zero atmosphere environment, a road flare burns for approximately 5 minutes and 5 seconds. Further testing required for different environments/configuration.

-Press O to toggle the flare light on or off. (O might not be true) Hold right click to light it. They are throwable holding Q.
+Road Flares are part of the starting gear and provide short-duration illumination with a distinct red glow. Each flare burns for approximately 3 minutes before burning out. While lit, the flare continuously releases heat [[energy]] into the surrounding [[atmosphere]], and can ignite combustible gas mixtures in the area. They can be painted with [[Spray Paint]] to change their glow color.
-It can generate heat and could be use as a cheap heat source to heat up a room.
-Beware it could ignite H2 if both H2 and O2 exists in the room!
-The heat energy of one road flare is 600kJ. Volume is constant in sealed rooms (8m^3 per one cube), as well as amount of matter, therefore only temperature and pressure are changed with heat energy, which is isochoric process. The equation for isochoric process is Q = Cv·n·ΔT, where Q stands for heat energy, Cv is molar heat capacity, n is amount of matter (in moles) and T is temperature. As a reference, one cubic volume of air (oxygen & nitrogen) at 100kPa and 20C has around 357 moles.
+= Usage =
-For example, with oxygen that means that means that one flare per one cubic volume can raise from -66C and 70kPa to 20C and 100kPa. From 20C and 100kPa one flare per cubic volume would raise temperature to 106C and pressure to 129kPa.
