They are concerned that there may be potentially hazardous ash, debris or residues on vessels or cargo bound for US ports.
"Vessels impacted by the Tianjin explosions are expected to call on US ports over the next several weeks. There have been no reports of vessels with confirmed hazardous debris or residues onboard," said the coast guard safety bulletin.
"For the purpose of this bulletin, an `impacted vessel` is any vessel that was in the Tianjin port complex, or that has loaded cargo or containers that were in the Tianjin port complex, at the time of the first explosion on 12 August through 15 August," it said.
While there was much media coverage of the Tianjin explosion, "there was not yet clarity of the full extent or nature of any possible chemical contamination that may be aboard impacted vessels.
"Vessel owners and operators should be aware of the potential for hazardous ash, debris or residues onboard impacted vessels or containers, particularly in cargo bays and interior spaces not regularly exposed to the elements," said the bulletin.
