What is the most critical immediate action for a Marine to take upon hearing the alarm for a gas attack or suspecting the presence of a chemical agent?
Answer: Stop breathing, close eyes, don and clear the protective mask.
The immediate action drill for a gas attack is to protect yourself first by stopping breathing, closing your eyes, and donning, clearing, and sealing your protective mask within 9 seconds. All other actions, such as reporting, decontaminating, or aiding others, follow this critical life-saving step.
Which of the following correctly describes the posture required for Mission Oriented Protective Posture (MOPP) Level 2?
Answer: Overgarment worn, boots worn, mask carried, gloves carried.
MOPP Level 2 requires the service member to wear the JSLIST overgarment and the protective overboots. The protective mask and gloves are carried. This level provides significant protection while minimizing the physiological burden of wearing the mask and gloves.
A Marine uses M8 detector paper to test a suspicious liquid on a vehicle. The paper turns yellow/gold. This indicates the probable presence of which type of chemical agent?
Answer: A G-series nerve agent (e.g., Sarin).
M8 detector paper is used to detect liquid chemical agents. A yellow/gold color indicates the presence of a G-series nerve agent (like Sarin or Tabun). Red/pink indicates an H-series blister agent, and dark green indicates a V-series nerve agent.
A Marine has been exposed to a liquid nerve agent on their forearm. After masking and receiving any necessary auto-injections, what is the primary piece of individual equipment used for immediate skin decontamination?
Answer: Reactive Skin Decontamination Lotion (RSDL).
Reactive Skin Decontamination Lotion (RSDL) is the current standard issue item for decontaminating skin exposed to chemical warfare agents. It neutralizes the agent on contact. The M295 kit is for equipment, and chlorine solutions are typically used for large-scale equipment decon, not immediate personal use on skin.
Your unit is conducting operations when a CBRN event occurs. You are the first to observe it. Which standardized report is used to pass the most critical, immediate information of the attack to higher and adjacent units?
Answer: CBRN 1 Report
The CBRN 1 Report is the initial observer's report. Its purpose is to provide immediate warning to other units by passing basic data about the attack (e.g., location, time, type of attack) as quickly as possible. This allows other units to take protective measures.
A Marine unit must operate in a contaminated area. The CBRN team reports that the primary threat is from an agent with low volatility that is an oily liquid, posing a significant and long-lasting contact hazard. This agent is best classified as:
Answer: Persistent.
Persistent agents are chemical agents that evaporate slowly, often having an oily consistency. They can contaminate terrain, equipment, and personnel for extended periods (hours to days), posing a long-term contact and vapor hazard. VX nerve agent and HD mustard agent are classic examples. Non-persistent agents, like Sarin, dissipate rapidly.
