Water and acid mixed together in certain concentrations can result in the development of dangerously high heat levels and aggressive reactions with steel surfaces. Which of the following is a general description of the approach to be adopted when cleaning a cargo tank after the discharge of Sulphuric Acid?
It is important that, once cleaning commences, large quantities of washing water can be delivered as quickly as possible, so that the acid is repaidly diluted.
It is critical that, as cleaning commences, washing water is introduced in a controlled manner, allowing time for the acid and water in the sump to mix slowly and thoroughly before the rest of the tank surfaces are flushed.
A mixture of hot fresh water and Sodium Hydroxide solution (50/50) should be prepared beforehand and then circulated around the tank, rapidly neutralising any remaining acid.
Any acid remaining in the sump should first be ejected and the tank ventilated for a minimum of 30 minutes before the introduction of any water, ensuring that there are insufficient acid residues to create any dangerous reaction.
