A major war has just ended. You have been ordered to search a natural gas plant to check for any explosives, however you soon become stranded. Searching through the files you found this note:
	
	To supervisor : 
There is an unidentified substance in the natural gas. It is extremely dangerous, and the plant is to be shut down immediately. All employees have been instructed to leave the facility upon arrival. Any employees currently inside the facility (including you) will be examined for bacterial infection. The plant's ventilation system will then be used to filter out the toxins. When the process has been completed, the plant can be restarted assuming all employees wear approptriate protective uniforms.

Standard search parties are formed after 3 days of a missing person. You entire team has been missing for a week, so there has got to be at least someone looking for you. If you can find a way to contact them, they may be able to save you.
