What is the self-aid response for choking agents?

When dealing with choking agents, the appropriate self-aid response focuses on protecting oneself from inhalation and exposure to the harmful substance. Putting on a mask immediately serves as the most effective first line of defense. The mask helps filter out harmful particles and gases, creating a barrier that protects the respiratory system from further damage.

In situations involving choking agents, the priority is to maintain an unobstructed airway and minimize contact with toxic agents. Other options, such as drinking water or attempting to calm oneself, do not directly address the immediate threat posed by choking agents. Running away might be beneficial in some contexts, but it does not provide immediate protection and may expose a person to greater risk if they lack proper protective equipment. Therefore, the emphasis on quickly donning a mask underlines the critical nature of immediate protective actions in hazardous environments.
