The emergency response team responded to a terrorist attack where hundreds of people died following symptoms of chest tightness, palpations, seizures, and finally paralysis. A colorless odorless liquid known as Sarin (GB) was the agent, which is primarily inhaled with limited exposure through the skin. The concentration of Sarin has not been measured. What level is the minimum level of personal protection and safety equipment (PPE) that would be needed?
Correct Answer: B
Rationale: The correct answer is B: Level B. In a scenario involving Sarin, a highly toxic nerve agent primarily inhaled, Level B protective equipment is required. Level B PPE includes a chemical-resistant suit, chemical-resistant gloves, chemical-resistant boots, and a full-face respirator with appropriate filter cartridges. The choice of Level B is based on the fact that Sarin is primarily inhaled, indicating the need for respiratory protection. Level A is typically used for the highest level of protection, including protection against highly toxic chemicals in both the air and on the skin, which is not necessary in this scenario. Level C and D do not provide adequate protection against a highly toxic chemical like Sarin.
