2.3 Hatch covers, cranes, ventilation and other systems 2.3.1 The condition of the hatch covers and other systems should be checked in advance of loading. In
this regard, specific items should be checked to ensure their good working order as follows below.
2.3.1.1 Hatch cover rubber sealing.All sealings (gasket packing) should be in good condition.
Any replacements or renewals should be made in complete lengths only. Sealings should
not be repaired in short lengths, and there should be no gaps. Sealings should not be
permanently or unevenly imprinted by more than 0.4 inches (10 mm), and should not be
hardened, worn, or delaminated as seen in Figure 2.1. 2.3.1.2 Hatch cover compression bars.Compression bars should have an even surface, and
should be free of damage and significant deformation as seen in Figure 2.2. 2.3.1.3 Hatch cover sealing channels.Sealing channels should be clear of corrosion and free of
damage and deformation.
2.3.1.4 Alignment of hatch covers. Cargo hatch covers should be correctly aligned.
2.3.1.5 Hatch cover wheels, rollers, hinges, etc.Wheels, rollers, hinges and other operational
parts and mechanisms should be in a fully operational condition, free of rust, free of
damage and deformation, and properly adjusted and greased.
2.3.1.6 Coaming non-return valves.Coaming non-return valves should be checked to be
operational, ensuring they are not blocked, are free of corrosion and, where appropriate,
have caps available for use (see Figure 2.3).
