Certain oil cargoes, such as aviation turbine kerosenes or diesel oils, are specifically noted in ISGOTT as having an inherent hazard that requires ship's staff to monitor tanks containing them when on passage. What is that hazard?
They can absorb oxygen during the refining process and later release it into oxygen deficient atmospheres such as the ullage spaces in cargo tanks; the spaces should be monitored and the atmosphere adjusted if necessary.
They can release acidic elements when the ship is passing through tropical sea areas and the sea temperature rises above 30 degrees Celsius. A sharp odour may give an indication od increased corrosion which will require examination and possible attention after discharge.
Through contact with the tank structure, they can release highly toxic and corrosive matter which will remain in the sludge and can burn human tissue badly during a manual cleaning process. This can be detected by a drop in PTL factor and periodic tests should be made by ship's staff.
Unless containing an inhibitor, they can release toxic vapours if remaining in the ship for in excess of 60 days. If the cargo expands, these vapours may be released onto deck via the P/V valves and become a safety concern if thery enter the ship's ventilation systems.
