    1. Health Hazard – Aspiration Hazard

      Definition – Aspiration refers to the entry of a liquid or solid chemical directly through the oral or nasal cavity, or indirectly through vomiting, into the trachea and lower respiratory system. Aspiration toxicity includes severe acute effects such as chemical pneumonia, varying degrees of pulmonary injury or death following aspiration.

      Classification – GHS has assigned two categories for aspiration toxicity:

      Category 1 – The most severe category and assigned for chemicals known to cause human aspiration toxicity hazards or to be regarded as if they cause human aspiration.

      Category 2 – Less severe category and assigned for chemicals which cause concern due to the presumption that they cause human aspiration toxicity hazards.

      Hazard Communication – The two categories are assigned a specific symbol and signal word, as seen below:

      Category 1 – Health hazard symbol with the “Danger” signal word

      Category 2 – Health hazard symbol with the “Warning” signal word
