Processes and techniques which may result in a gas accumulation. The following circumstances may result in the unintentional build-up of asphyxiant gases in confined spaces. During MIG, MAG or TIG welding on the outside of fabrications, torch shielding gas can enter the fabrication through the weld root.
So here's how to make paper mache glue from water and flour so they can get their hands messy. What you need. Activity.

2 Answers 2. No, the paper will not burn without oxygen being present. Paper is made primarily of cellulose which is a polymer of glucose. If you heat paper in a vacuum the cellulose simply decomposes to $\ce{H2O}$, $\ce{CO2}$, $\ce{CO}$ and carbon. As the paper decomposes it will char or turn brown to black as the cellulose polymer degrades.
