🔍 Key Concepts

• A-class divisions under SOLAS and fire protection regulations • The meaning of the number (e.g., 0, 15, 30, 60) in labels like A0, A30, A60 • Difference between minutes and seconds in fire-resistance ratings

💭 Think About

• What does an A-class fire division have to do in terms of preventing passage of flame and limiting temperature rise? • When you see a rating like A60, what does the 60 usually represent in fire-protection standards? • Which options are talking about fire resistance versus unrelated topics like stability or yard construction specs?

✅ Before You Answer

• Verify that A-class refers to a fire-resisting division, not stability or structural strength against flooding. • Check that the number following the letter (e.g., 60) is measured in minutes, not seconds. • Confirm that the description includes both: no passage of flame for the rated time and limitation of temperature rise on the unexposed side.
