In-House Training Questionnaire; Enclosed Space Entry

Choose the one that is not a valid definition of an enclosed space:

• A space that has limited openings for entry and exit, poor natural ventilation and is not designed for continuous worker occupancy

• A space that is always open to the atmosphere and provides free airflow from all directions

• A space that may contain hazardous atmospheres due to restricted airflow, such as cargo holds, ballast tanks, or fuel tanks

• A space that requires special precautions before entry, including gas testing, ventilation, and a permit-to-work

What are some common examples of enclosed spaces encountered in marine environments?

• Cargo Holds, Ballast Tanks, Double Bottoms, Cofferdams, Void Spaces, Chain Lockers

• Cargo Ballast, Cabin Store, Forecastle Deck, Car Spaces, Chain Link

• Cargo Hatch, Ballast Water, Double Deck, Car Spaces, Chain Link

• Cargo Slings, Ballast Residue, Double Barrel, Bilge Sounding.

Why have legal requirements been established for entry into enclosed spaces?

• To protect workers from serious illnesses associated with working in open space

• To protect workers from serious injuries associated with working in cargo space

• To protect workers from serious hazards associated with working in open space

• To protect workers from serious hazards associated with working in enclosed space

What SOLAS Regulation require a ship to implement enclosed space entry and Rescue Drill every two months?

• SOLAS Chapter III, Regulation 18

• SOLAS Chapter III, Regulation 17

• SOLAS Chapter III, Regulation 19

• SOLAS Chapter III, Regulation 16

What is a Permit-to-Work (PTW) system, and how does it apply to enclosed space entry?

• A process that help determine what could go wrong, how likely it is and how to cotnrol or eliminate those risk.

• Formal written authorization for entry and specifics identified hazards control measure, authorized entrants and emergency procedure.

• Revised recommendations for entering

• Proper procedures are essential to protect workers entering confined spaces from injury or death due to hazardous conditions

What is the minimum acceptable oxygen concentration required for safe entry into confined or enclosed spaces?

• 19.5% - 20.9%

• 10.5% - 10.9%

• 18.0 - 18.9%

• 00.6 - 00.9

Why is hazard identification and risk assessment critical before entering an enclosed space?

• Physically isolate the space from all connected systems.

• Prevent accidental release of liquids, gases, or solids into the space

• A process that helps determine what could go wrong, how likely it is, and how to control or eliminate those risks

• A ship construction method where a second, watertight inner hull is placed beneath the main hull, creating a space for storage and protection.

_____ process wherein you physically isolate the space from all connected systems and prevent accidental release of liquids, gases, or solids into the space?

• Cleaning

• Permit to Work

• Ventilation

• Isolation

What are the responsibilities of the Standby person (Attendant) during enclosed space entry operations?

• Confirm that rescue plans and equipment are ready

• Remain outside the space at all times

• Performs planned, practiced rescues using correct procedure

• Signals distress clearly if needed

What is the fundamental rule for conducting emergency rescue in an enclosed space?

• Simulations should reflect realistic scenarios

• Connect lifelines to entrants when necessary

• No untrained person should ever attempt a rescue

• Drills must be conducted every 3 months.
