Which type of respirator is required when entering a tanker cargo tank with an oxygen-deficient atmosphere?
Answer: Self-contained breathing apparatus (SCBA)
An SCBA supplies its own air and is mandatory for oxygen-deficient or immediately dangerous to life or health (IDLH) atmospheres.
What is the primary purpose of a safety harness worn during tanker cargo operations?
Answer: To allow rescue from confined spaces and prevent falls
Safety harnesses are used to facilitate retrieval from confined spaces and to prevent falls from elevated work areas.
Which chemical protective suit classification offers the highest level of skin and respiratory protection?
Answer: Level A fully encapsulated suit
Level A suits are fully encapsulated and provide the highest protection against vapors, gases, and chemical splashes.
A crew member smells a strong hydrocarbon odor on the cargo deck. What is the correct immediate action?
Answer: Stop work, alert personnel, and report to the officer in charge
Any unexpected hydrocarbon odor must be treated as a potential gas leak—work stops immediately and the situation is reported to the OOW.
What minimum flash point distinguishes a flammable liquid from a combustible liquid under US regulations?
Answer: 100°F (38°C)
Under US OSHA and DOT rules, a combustible liquid has a flash point at or above 100°F (38°C), while below that it is classified as flammable.
Which piece of PPE is specifically designed to protect against static discharge when taking manual tank gauging samples?
Answer: Anti-static (ESD) wrist strap attached to the ship's structure
An anti-static bonding strap equalizes potential between the gauger and the tank, preventing ignition from static discharge.
How often must fixed gas detection systems in tanker cargo pump rooms be tested according to standard industry practice?
Answer: Before each cargo operation and at regular intervals per SMS
Fixed gas detectors in pump rooms must be functionally tested before cargo operations and at intervals specified in the vessel's Safety Management System.
