🔍 Key Concepts

• Static accumulator cargoes vs non-accumulators (often discussed in tanker safety guidance) • Relationship between viscosity (how thick a liquid is) and static build‑up during pumping • Which petroleum products are usually handled with stricter loading precautions because of static

💭 Think About

• Think about which of these liquids flows the most freely through pipes and hoses at normal temperatures, creating more friction and static charge • Consider which products on the list are normally very thick or even semi‑solid at ambient temperature, and whether those are likely to build up static as much • Ask yourself: on tankers, which type of petroleum cargo usually has special warnings about splash filling and the need for longer settling times because of static?

✅ Before You Answer

• Identify which listed cargo is a light, free‑flowing petroleum liquid rather than very heavy or semi‑solid • Eliminate products that are typically high‑viscosity (very thick) or almost solid at room temperature • Recall that strong static precautions are usually associated with refined or lighter petroleum products rather than the heaviest residues.
