  • COSMO Co., Ltd. vide Notice Letter dated 02 August 2017 had stated that insulation material is partly missing from the upper parts, sides and bottom of the fire doors manufactured by COSMO and matching the following criteria may be affected

    2. Certified to MED Modules B and D, Type-approved and certified by DNV-GL; and
    3. Produced between November 2013 and July 2017.

  • COSMO has advised below onboard check to determine whether the fire doors are affected by the quality issue:
    1. Remove a rivet or hinge bolt on the side of the door.
