🔍 Key Concepts

• 46 CFR requirements for emergency outfits on tank vessels over 1000 gross tons • What makes a flashlight safe for use in flammable atmospheres on tankers • The meaning of terms like explosion proof, NEMA listing, and Type II/III

💭 Think About

• Think about which of the listed properties are directly related to preventing ignition in a cargo tank or pump room environment. • Ask yourself whether the regulation requires a specific safety type of flashlight, a particular standard or listing, a certain design type (II/III), or a combination of these. • Consider whether regulations for tank vessels tend to focus on one main safety characteristic or multiple overlapping standards for equipment like flashlights.

✅ Before You Answer

• Verify in 46 CFR Subchapter D (Tank Vessels) what is explicitly stated about emergency flashlights (wording and minimum number). • Check which of the answer choices are actually regulatory terms commonly used in USCG equipment requirements for hazardous locations. • Confirm whether Type II or Type III describes the same classification system as “explosion proof type” or “NEMA listed,” or if they refer to a different standard entirely.
