Question 1 of 27070

Blocks and falls used as lifeboat gear must be designed with which minimum safety factor?

🔍 Key Concepts

• SOLAS and LSA (Life-Saving Appliances) Code requirements for launching appliances and lifeboat gear • Difference between safety factor, working load, and breaking strength • How regulations define the basis for calculating the safety factor (what weight or load you start from)

💭 Think About

• Look at each choice and ask: what is the load condition the regulation actually uses for calculating safety factor—normal working load, fully-loaded weight, maximum stress, or breaking strength? • Think about why lifeboat blocks and falls need a conservative design: in an emergency, how are they loaded and what condition must they safely handle? • Which option correctly pairs a realistic safety factor value used for life‑saving gear with the proper reference load (not just generic stress or breaking strength)?

✅ Before You Answer

• Verify in the LSA Code / SOLAS Chapter III how safety factors for launching appliances and lifeboat falls are defined. • Check whether the regulation talks about working load of the survival craft or breaking strength of the wire or maximum allowable stress. • Confirm which numerical safety factor (4, 5, 6, or 8) is actually specified for blocks and falls used as lifeboat gear, not for other equipment.

Blocks and falls used as lifeboat gear must be designed with which minimum safety factor?

6, based on the weight of a fully-loaded survival craft

5, based on the maximum allowable stress

8, based on the normal working load of a survival craft

4, based on the breaking strength of the wire
