USCG Deck Side Safety 4 — Questions and Answers
Question 1: What is the USCG requirement for 'hot work' (welding, cutting, grinding) on a vessel?
- Any crew member may perform hot work if wearing goggles
- A hot work permit must be issued and a fire watch maintained during and after the work (Correct answer)
- Hot work is only permitted in port
- Only the chief engineer may authorize hot work in writing
Correct answer: A hot work permit must be issued and a fire watch maintained during and after the work
USCG regulations require a formal hot work permit and a dedicated fire watch stationed during and for a set period after all welding, cutting, or grinding operations.
Question 2: A life ring is thrown to a person in the water. What additional action should immediately follow?
- Sound the general alarm and mark the position (MOB marker/GPS waypoint) (Correct answer)
- Stop the vessel immediately at full astern
- Deploy the sea anchor
- Lower the anchor to slow the vessel
Correct answer: Sound the general alarm and mark the position (MOB marker/GPS waypoint)
After throwing a life ring, the next priority is sounding the general alarm to alert the crew and marking the MOB position with a GPS waypoint or MOB marker to aid recovery.
Question 3: Which OSHA/USCG standard governs the use of personal fall arrest systems on commercial vessels?
- 46 CFR Part 12 — Merchant Mariner Credentials
- OSHA 29 CFR 1910.140 and USCG guidance on fall protection for maritime workers (Correct answer)
- 46 CFR Part 90 — General Provisions, Inspected Vessels
- SOLAS Chapter II-1 — Construction
Correct answer: OSHA 29 CFR 1910.140 and USCG guidance on fall protection for maritime workers
OSHA 29 CFR 1910.140 covers personal fall protection systems, and USCG guidance incorporates these standards for commercial vessel operations.
Question 4: What is the purpose of 'snap-back zones' marked on a vessel's deck?
- Areas where crew must stay during bunkering
- Areas crew must avoid standing in due to the recoil path of mooring lines under tension (Correct answer)
- Designated zones for heaving lines to be coiled
- Safe standing areas during cargo operations
Correct answer: Areas crew must avoid standing in due to the recoil path of mooring lines under tension
Snap-back zones mark the predicted recoil path of mooring lines if they part under tension, and crew must never stand in these areas during mooring operations.
Question 5: When must a vessel sound the danger signal during maneuvering?
- Whenever passing another vessel at night
- When doubt exists about the intentions of another vessel (five or more short blasts) (Correct answer)
- Before entering any port
- When operating in restricted visibility only
Correct answer: When doubt exists about the intentions of another vessel (five or more short blasts)
Five or more short blasts on the whistle is the danger signal, sounded when a vessel is in doubt about another vessel's intentions or action.
Question 6: A crew member is using a portable power tool on deck in wet conditions. What is the primary electrical safety requirement?
- Use rubber gloves only
- The tool must be connected through a Ground Fault Circuit Interrupter (GFCI) (Correct answer)
- Work must stop immediately and resume only when the deck is dry
- A second crew member must hold the power cord
Correct answer: The tool must be connected through a Ground Fault Circuit Interrupter (GFCI)
GFCI protection is required when using portable electric tools in wet locations to prevent electrocution by detecting ground faults and cutting power instantly.
Question 7: What is the correct way to dispose of oily rags used during maintenance on the main deck?
- Wash them overboard with seawater
- Place them in a covered, self-closing metal container designated for oily waste (Correct answer)
- Store them in a plastic bag in the bosun's locker
- Burn them in the ship's incinerator immediately
Correct answer: Place them in a covered, self-closing metal container designated for oily waste
Oily rags are self-ignition hazards and must be stored in covered, self-closing metal containers designated for oily waste to prevent spontaneous combustion and environmental violations.
