.. Extinguishing the fire

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'. (It looks like the number 5, but it's the letter S. Promise.)

If we ignore the numbers, the 'CA' and 'S' may refer to elements. Hope you paid attention in science class! (Check out the board near the machine.)

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. (Open everything you can!)

You can find a spray bottle in a cabinet near the vent we've been using to access 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.

That's the majority of the fire dealt with - now we just need an ID card!
