The notes we found in the laboratory are complicated, but imply that we can make our own fire extinguisher.

By, and I quote, 'mixing native substance with diverse local elements'.

Basically, mixing a bunch of chemicals. You can read it yourself by examining the notes in your inventory.

For an active fire extinguisher, the sheet says '1-CA' and '3-S'.

If we ignore the numbers, the 'CA' and 'S' may refer to elements. Hope you paid attention in science class!

The periodic table has the answers - 'CA' is calcium, and 'S' is sulfur.

The machine behind us can apparently dispense both - we'll just need a container to hold it.

We're limited to the places we can access right now, so make sure you've searched every room thoroughly.

You can find a spray bottle in a cabinet near the vent that connects to the laboratory.

Put the spray bottle in the machine's container slot, and get mixing!

We're mixing calcium and sulfur - the notes seemed to imply 1 dose of calcium, and 3 doses of sulfur.

The levers are labelled with the elements they dispense, so it's up to you to mix the correct amount.

When you've added 3 doses of sulfur and 1 dose of calcium, pull the 'mixer lever' to put the substance in the bottle.

If you've accidentally made the wrong mixture, use the 'discard lever' to start again.

By using the sprayer on the fire, that'll get rid of the immediate problem - now we just need an ID card!
