How to reduce Hydrogen Sulphide Hazard in Residual Fuel Oils?
Direct Answer
Option A: Ventilation to lower the concentration of vapour in the ullage space and in specific areas where vapours may accumulate should be carried out as soon as practicable.
Hydrogen Sulphide (H2S) is a highly toxic gas that can accumulate in ullage spaces of tanks carrying residual fuel oils. As per ISGOTT, effective ventilation is crucial to dilute and remove H2S vapours, reducing the concentration below hazardous levels and ensuring a safer working environment for personnel.
