Question Description

Write a minimum of one page for each hazard you choose (a minimum of three pages total), which summarizes the following information:

  • Explain whether the substance is a chemical or biological hazard, and explain how you determined that.
  • Explain the key chemical properties (vapor pressure, vapor density, molecular weight, relative size) as applicable, and describe how these properties affect the different routes of exposure. Based on the chemical properties, how would you identify which exposure route is the most important?
  • Analyze how the substance could enter the body through the dermal route, and discuss why the dermal route would or would not be important.
  • Describe the region of the respiratory system where deposition would be expected (only for the aerosol hazard).

Hydrogen Sulfide

Hydrogen sulfide is among the most risky chemical hazards. Hydrogen Sulfide is a toxic
colorless and combustible gas which has a characteristics of foul egg smell that is noticeable in
concentrations as low as 0.5bbp. It is sometimes referred to as sour gas due to its rotten egg odor
although, when it is highly concentrated it becomes odorless. Hydrogen sulfide is a toxic gas that
can lead to both minor and lasting effects to individuals who have been exposed to it. The gas is a
bit denser than air and may be accumulated areas that have bad ventilation and enclosed. Hydrogen
sulfide is a chemical compound with the formula H2S since it reacts as an acid and a reducing
agent.

Hydrogen sulfide molecular H2S, S or S8 and a molecular weight 34.076 g/mol. Children
are more vulnerable to these chemical than adults due to the small diameter of their airways.
Prolonged exposure to hydrogen sulfide and also relatively small exposures can cause pain on the
skin and a burning sensation on the eyes. Direct contact with the liquefied gas can cause frostbite.
At room temperature hydrogen...
