Before entering a cargo tank pump room, what must occur?

Before anyone can safely enter a cargo tank pump room, it is crucial that the area be inspected by a marine chemist. This step is essential because it ensures that the atmosphere within the pump room is safe for entry, particularly regarding the presence of potentially harmful gases or contaminants. A marine chemist performs tests to confirm that the air quality meets safety standards for human occupation, which involves measuring flammable or toxic gas concentrations and assessing oxygen levels.

While evacuation, testing for leaks, or flushing the area may be necessary steps in certain scenarios or as part of standard operational safety procedures, none of these alone address the critical need for a qualified professional to inspect and certify the safety of the space. Certification from a marine chemist guarantees that safety protocols are adhered to and that personnel can enter the pump room without risk.
