If an operator inhales chlorine gas, which action would be performed first?

• A. Immediately remove victim from the contaminated area
• B. Immediately call a physician or paramedic
• C. Immediately begin appropriate treatment
• D. Do nothing because chlorine gas is nontoxic

Answer: (B)

When exposure to a toxic gas like chlorine is suspected, getting professional medical evaluation immediately is crucial because chlorine can cause rapid breathing problems and may lead to delayed complications. A physician or paramedic can assess airway irritation, monitor breathing, and decide on treatments or need for transport, which is essential even if symptoms seem mild at first. The safety step of moving away from the contaminated area is important, but delaying medical assessment for immediate treatment or assuming it isn’t necessary can miss evolving injuries. Chlorine gas is toxic, so taking no action isn’t appropriate.
