Question 41Safety & Environmental - QMED

The correct answer is A) The tanks which are safe to enter when the certificate was issued. A marine chemist's certificate provides information on the atmospheric conditions within a tank barge's compartments at the time the certificate was issued. It confirms which tanks are safe for entry, typically by verifying that the oxygen content and flammable vapor levels are within acceptable limits. This allows crew to safely perform inspections, maintenance, or other work within the certified tanks. The other options are incorrect as the certificate does not provide information on the cargo quality, the barge's stability, or the required number of fire extinguishers.
