New guidelines on tank entry tankers using nitrogen as an inerting medium have been released by the Internatonal Maritime Organisation. Nitrogen is used to prevent explosive atmospheres in tanks by reducing the level of oxygen as well as to ‘pad’ chemical cargoes against contamination.

A number of non-tank vessels use nitrogen for other purposes and the guidelines should also be applied in such cases.

Nitrogen not only displaces the oxygen need to live by also the carbon dioxide that triggers the breathing reflex.

Fatalities have occurred when seafarers have entered tanks which were wholly or partially inerted.

The guidelines point out that a deep breath of 100 per cent nitrogen will kill.

What happened?

This alert is to advise you on a fatality incident which occurred on 9th April 2011 in Indonesia.

Three workers lost their lives and one other narrowly escaped death when they entered a dewatering tank after initial preparation activities prior to a coil tubing well unloading operation.

One worker entered the tank initially and lost consciousness. The others entered to rescue him. The individuals were asphyxiated by Nitrogen. Continue reading »

The Case Of The Silent Assassin

In September 2007, after broadcasting several audio podcasts and blog posts on the subject we realised that confined space/enclose space casualties were disturbingly common and seemed to be a major issue that wasn’t going away. We wanted to do something, however modest, to help address the situation. We discussed the issue with IDESS Interactive Technologies, which shared our concerns, and we agreed to collaborate in the production of three animated versions of MAC podcasts of which the first was to The Case Of The Silent Assassin, based on the Sapphire incident investigated by Ron Strathdee of the Isle Of Man registry.

Amendments by the International Maritime Organisation, IMO, to mandate the use of inert gas, IG, on oil and chemical tankers carrying low flashpoint cargoes are being opposed by the International Parcel Tankers Association, IPTA,in part because of what it believes will be heightened dangers during confined and enclosed space entries.

Says IPTA: “IPTA is concerned that the imposition of a mandatory IG requirement is widely viewed as a kind of¬†universal panacea that will automatically protect seafarers. We feel it important that those involved in the debate should have a full understanding of all the underlying issues, including the operating practices of the chemical tanker trade, which are very different from those of the oil tanker trade, and could lead to chemical tanker crews facing even more risk from asphyxiation than from the dangers nitrogen IG would be intended to protect them from.” Continue reading »

Ships are dangerous places for the badly trained, the unwary, the careless. In this case two seafarers were killed by almost nothing.
