According to Notice B from the DMA, immersion suits on board Danish flagged cargo ships must be of a type that is in accordance with the LSA Code, regulation 18.104.22.168, that ensures thermal protection for six hours. However, the DMA accepts any wheel-marked immersion suit that is in accordance with the Marine Equipment Directive 96/98/EC.
On cargo ships, additional immersion suits must be provided at remotely located watch or work stations, including remotely located survival craft. Reference is made to MSC.1/Circ.1243, “Unified interpretation of SOLAS chapter III”. In the opinion of the DMA, the number of additional suits should be a minimum of two. On small vessels where there is only one watchkeeping officer in the machinery space, the number of additional immersion suits may be reduced to one.
