What is the function of an emergency escape breathing device (EEBD) on a tanker?
Answer: To provide a short-duration air supply for crew to escape from a smoke-filled space
EEBDs provide a short-duration supply of breathable air (typically 10–15 minutes) to allow crew to escape from smoke-filled or oxygen-depleted spaces.
Which condition makes a cargo tank 'gas-free' and safe for hot work?
Answer: Oxygen above 19.5% and hydrocarbon vapor below 1% LEL
A gas-free tank requires oxygen levels above 19.5% for safe occupancy and hydrocarbon vapor below 1% of the lower explosive limit to prevent ignition.
What is the FIRST step in the event of a cargo spill that poses a fire risk on deck?
Answer: Stop the source of the spill and eliminate all ignition sources
