The U.S. Coast Guard’s Safety Alert 13-26 highlights deficiencies in gas detection and atmospheric testing practices aboard bulk carriers transporting cargoes that may emit flammable or toxic gases, such as coal.

Two explosions aboard bulk carriers carrying methane-emitting coal in 2023 and 2025 underscore the hazards associated with these cargoes. The investigations remain ongoing, and no cause has been determined. The Coast Guard emphasizes the importance of properly maintained and calibrated gas detection equipment, appropriate calibration gases and regulators, and crew familiarity with the specific instruments and manufacturer procedures.

The alert recommends verifying gas detection equipment is operational, properly calibrated, and ready for use before loading hazardous gas-emitting cargoes, along with ensuring personnel are properly trained in its operation and testing procedures.
