Why is is especially necessary to continue to ventilate the tank and to continuously monitor the atmosphere when working inside a cargo compartment which still contains vegetable oil residues?

For a tank which has contained vegetable oils, if it is continuously ventilated an Enclosed Space Entry Permit is not required. However, for anyone entering the compartment without a permit in place, they must carry an oxygen meter which continuously monitors the atmosphere.

Forced ventilation will create a hard "skin" on the residues, making them safer to stand on. Testing the atmosphere will indicate when this skin has formed, as no further vapours will be released.

Vegetable oils are commonly washed using very hot water. Forced ventilation will make the temperature inside the compartment better to work in. Monitoring the atmosphere will indicate if the humidity is increasing.

Because the decomposing residues continue to release hazardous gases, reducing the levels of oxygen in the tank and making the atmosphere potentially dangerous.

You are going to inspect a fresh water tank together with one of the Engineers. Is it safe enough to open the manhole and enter the tank (it is only fresh water) or do you have to take extra precautions before entering?

Bring a flashlight and put on safety shoes

Use a breathing apparatus if the oxygen level is below 21%

Remember to have a colleague standing by to assist you if any problems
