A Doomed Pilgrim in the Ruins of the Future

You are not doing too well, Luckily for you all the falling sand is still warm and has made a surface between you and the icy ground. However, being sand it has made your crawl that much more difficult. Your trip to the factory has been longer and more exhausting than you expected. To make matters worse some of the small spiders survived the fall. In your compromised state you couldn't really keep them off. They sit dormant now, hiding from the cold in the folds of your clothes.

You feel exhausted and practically dead. Which is what you will probably be if you do not receive some sort of medical attention.

The factory, though abandoned, looks like it was only recently abandoned and is still in running order. It appears that an automatic heating system is still running as you arrive.

I take a moment to brush away the spiders before turning my attention back to the factory.
What's the best way for me to get inside?
Anyone should answer.
