Maersk Line has stopped loading dangerous goods in areas close to the accommodation and engine casing units on its boxships as it carries out tests to determine the cause of the Maersk Honam blaze.
The fire claimed the lives of three crew members, with another still missing.
Maersk insists there is no evidence the fire some 340 miles off India's Lakshadweep archipelago was caused by dangerous goods and said all cargoes were loaded in line with the safety measures outlined in the International Maritime Dangerous Goods Code.
