Which device is used to remove smoke and gases during ventilation?

• A. Desmoking kit
• B. PEARS
• C. NFTI
• D. SCBA

Answer: (A)

During ventilation, the aim is to purge a space of smoke and toxic gases by forcing a directed flow of air through the compartment, pushing contaminants out and bringing in fresh air. The desmoking kit is designed for this exact job. It provides the necessary hoses, connections, and typically a desmoking fan to establish a purge path, so smoke and gases are moved toward exhaust and replaced with clean air. This rapid clearance improves visibility and safety for crew entering the space for inspection or repair. Other devices like SCBA supply breathable air to individuals working in the smoke, but they do not remove smoke from the space itself; they protect the wearer rather than purge the environment. The remaining items have different roles and are not used to carry out the purge during ventilation.
