Gas
What are the changes between states of matter
Melting – Change from a solid to a liquid
Evaporation - Change from a liquid to a gas
Condensation - Change from a gas to a liquid
Freezing - Change from a liquid to a solid
Sublimation - Change from a solid to a gas
Deposition - Change from a gas to a solid

Poisonous & Infectious Materials(Class 1)
Material causing immediate and serious toxic effects
Materials which are potentially fatal or may cause permanent damage if inhaled, swallowed, or absorbed through the skin, or may burn the skin or eyes upon contact
Poisonous & Infectious Materials(Class 2) – Toxic Materials
Material causing other chronic or long term effects
Material which may cause death or permanent damage as a result of repeated exposure over an extended period of time; may be an irritant to the skin, eyes, or respiratory system; may cause cancer, birth defects, or sterility
Poisonous & Infectious Materials(Class 3)- Biohazards
Materials which may cause disease in humans and animals, such as viruses, bacteria, and fungi; may also include cultures and diagnostic specimens such as blood, urine, and body tissue
Corrosive Material
Material which may corrode aluminum and steel or human flesh
Can be liquid or gases
Dangerously Reactive Material
Materials which become self-reactive under conditions of shock, or increased temperature or pressure
Materials which react vigorously with water to produce a very toxic gas
