What is a common use for a smoke bomb in marine applications?

The use of a smoke bomb in marine applications is particularly relevant for verifying that cabin air ducting is properly isolated from engine room ventilation. When conducting this verification, a smoke bomb can effectively visualize airflow patterns and show whether smoke (representing potential contaminants or hazardous gases from the engine compartment) is entering the cabin space. This is critical for ensuring the safety and comfort of individuals on board, as it helps to confirm that any fumes or odors from the engine room do not infiltrate living quarters, thereby preventing potential health hazards.

Using a smoke bomb in this manner allows technicians and examiners to clearly see any points of crossover between systems that need to remain isolated. This is paramount when designing and maintaining a marine vessel's ventilation system, as well as meeting safety standards and regulations set by organizations such as ABYC. Ensuring proper isolation helps in achieving adequate air quality in cabins and preventing dangerous situations stemming from engine gases.
