Sometimes, chemical leaks occur aboard ships. Many different types of systems could potentially be a leak source. One such system are refrigeration systems.
Refrigerants sometimes end up leaking out of vessel refrigeration systems. Such chemicals can be quite hazardous. Ammonia and halocarbons are two types of hazardous chemicals that are sometimes used as refrigerants aboard ships. When a vessel experiences leaks of these sorts of chemicals, it can pose major safety risks to workers, such as chemical exposure risks (being exposed to substantial levels of these types of refrigerants can cause a wide range of health problems) and fire/explosion risks.
