Question 2871 Deck General

The correct answer is B) paralyze your breathing system. High concentrations of H2S gas can have a paralytic effect on the respiratory system, causing breathing to stop. This is due to the toxic nature of H2S, which inhibits the body's ability to utilize oxygen at the cellular level. As H2S exposure increases, it can quickly lead to respiratory failure and loss of consciousness. The other options, while potentially related to H2S exposure, do not accurately describe the primary effect of high concentrations on personnel. Dizziness, eye inflammation, and muscle contractions may occur, but the most immediate and dangerous impact is the paralysis of the breathing system, which can be fatal if not addressed promptly.
