This is a chemical that is yellow and has a musty odor. It's toxic when inhaled and violently reacts with water. It can cause coughing, short breath, headache, weakness, fever, chest pain, pulmonary edema, pneumonitis, and asthma. If it comes in contact with the skin it could cause frostbite, and eye irritation.
This is one of Ghostie's favorite chemicals to use and a new design.
