OBS Passenger Safety & Service 3 — Questions and Answers
Question 1: A passenger is trailing their hand in the water while the boat is underway. What hazard does this create?
- It creates unnecessary drag slowing the vessel
- It can attract fish, causing a navigational distraction
- It risks injury from the propeller or collision with debris (Correct answer)
- It is only dangerous in saltwater due to marine life
Correct answer: It risks injury from the propeller or collision with debris
Trailing limbs over the side can result in serious propeller injuries or impact with floating debris, and operators must warn passengers against this.
Question 2: Which statement about carbon monoxide (CO) and boat passengers is TRUE?
- CO is only dangerous below decks on sailboats
- Passengers at the stern near the engine exhaust are at highest CO risk (Correct answer)
- CO has a strong odor that passengers will detect immediately
- CO poisoning occurs only when the engine is off
Correct answer: Passengers at the stern near the engine exhaust are at highest CO risk
Passengers sitting at the stern close to exhaust outlets can be exposed to dangerous CO levels, especially at slow speeds or when the vessel is idling.
Question 3: What is 'swimmer's danger zone' or the 'no-zone' on a motorboat?
- The area directly off the bow where anchor lines are deployed
- The area within 100 feet of a marked swim buoy
- The area around and under the stern near the propeller (Correct answer)
- The area within 50 feet of another vessel's wake
Correct answer: The area around and under the stern near the propeller
The area around and under the stern is extremely hazardous because of propeller rotation, and swimmers or passengers must never enter this zone.
Question 4: If a passenger is injured aboard your vessel, which step should the operator take immediately after ensuring the scene is safe?
- Continue to the destination to save time before seeking help
- Assess the injury and apply first aid while calling for help if needed (Correct answer)
- Ask other passengers to vote on the best course of action
- Document the injury in the ship's log before doing anything else
Correct answer: Assess the injury and apply first aid while calling for help if needed
The operator should promptly assess the passenger's condition, administer first aid if trained, and contact emergency services if the injury is serious.
Question 5: Which passenger behavior should an operator actively prevent to avoid capsizing?
- Wearing life jackets with loose straps
- Moving together to one side of the boat to look at something (Correct answer)
- Eating or drinking non-alcoholic beverages on deck
- Using marine radios without authorization
Correct answer: Moving together to one side of the boat to look at something
Passengers clustering on one side shifts the center of gravity, causing the vessel to list severely and potentially capsize.
Question 6: Under what condition is it safest to refuel a boat with passengers aboard?
- It is always safest to refuel with passengers aboard to save time
- Passengers may remain aboard only if hatches and ports are closed
- Passengers should disembark and move away from the vessel during fueling (Correct answer)
- Passengers may stay if they hold their breath during fueling
Correct answer: Passengers should disembark and move away from the vessel during fueling
All passengers should disembark and move away from the boat while fueling to eliminate ignition sources and reduce exposure to fuel vapors.
Question 7: A passenger reports feeling dizzy and nauseous with a headache shortly after boarding a vessel with a running generator. What should the operator suspect?
- Seasickness caused by wave motion
- An allergic reaction to saltwater
- Carbon monoxide poisoning (Correct answer)
- Dehydration from sun exposure
Correct answer: Carbon monoxide poisoning
Dizziness, nausea, and headache are classic early symptoms of carbon monoxide poisoning, which can come from generator exhaust.
