Which type of smoke detection system is typically found in cargo holds?

Air sampling smoke detection systems are particularly effective in cargo holds because they continuously monitor air quality and can detect smoke particles in concentrations that may be too low for other types of detectors to identify. These systems work by drawing air through sample points in the cargo hold, where it is analyzed for the presence of smoke.

This is essential in cargo holds, as these areas can contain dense materials that may obstruct traditional smoke detectors. Additionally, the ability to detect smoke in its early stages enables quicker response times, which is critical for fire safety in enclosed spaces like cargo holds.

In contrast, other smoke detection types, such as optical or photoelectric detectors, might not be suitable in these environments due to potential blockages or the presence of various substances that may hinder their effectiveness. Ionization detectors, while useful in certain scenarios, are generally better suited for detecting fast-flaming fires and may not respond as effectively to smoldering fires that are more common in cargo storage scenarios.
