Common gas hazards include: Carbon Monoxide (CO), Combustible Gases, Hydrogen Sulphide (H2S), Refrigerant Gases (Ammonia and F-Gases) and O2 (Enrichment/Deficient).

Gas detection is particularly important in the marine industry due to undisturbed, closed, and watertight environments such as motor rooms, gas tanks, and various freight storage.

Long periods of time will pass without ventilation and these areas are likely to contain potentially toxic or explosive gases.

Oxygen displacement is normally caused by inert gases such as Nitrogen aboard oil tankers. Effective oxygen detection (enrichment and depletion) is critical in confined spaces and can be achieved using fixed gas sensors.

Explosive and toxic gases come from ballast tanks (CO2), combustion of fuel in motor rooms (hydrocarbon vapours), cold rooms (ammonia or refrigerant gases), wastewater (Hydrogen Sulphide).
