    Hazard

    • 2-mechanical
    • 3-chemical

  70. a result from some dominant physical force
    mechanical stress on a container
  71. a result of a reaction or interaction between a chemical(s) coming in contact with the container or its contents, it may also be a result of a change in the contents alone.
    Chemical stress on a container
