Exercise: Identifying EHS in a Scenario
Scenario: A chemical manufacturing plant accidentally releases a substance into a nearby river. The substance is known to be highly toxic and corrosive, causing burns and respiratory problems. It can also accumulate in the food chain, posing long-term risks to wildlife and humans.
Task: Based on the information provided, identify the potential extremely hazardous substance involved and explain your reasoning. Use information from the text and your knowledge of EHS to support your answer.
Exercice Correction
Based on the provided information, the potential extremely hazardous substance involved could be a strong acid like sulfuric acid (H2SO4) or nitric acid (HNO3), or a strong alkali like sodium hydroxide (NaOH) or potassium hydroxide (KOH).
Here's why:
- Highly Toxic and Corrosive: Both strong acids and bases are known to be highly corrosive, causing burns on contact with skin and other tissues. This aligns with the description of the substance causing burns and respiratory problems.
- Accumulates in the Food Chain: Heavy metals like lead, mercury, and cadmium are persistent pollutants that accumulate in the food chain. While not mentioned in the text, these metals can cause various health problems and are often considered EHS.
It's important to note that without further information about the specific properties of the substance released, it's difficult to pinpoint the exact chemical. However, the characteristics provided strongly suggest an EHS with corrosive properties, potentially posing long-term risks due to bioaccumulation.
