According to the Chemical Data Guide, which extinguishing agent should be used on a petrolatum fire in an open area?

🔍 Key Concepts

• Chemical Data Guide recommendations for specific cargoes and products • Differences between extinguishing agents on flammable solids vs flammable liquids/semisolids • How open area ventilation affects the choice of firefighting agent

💭 Think About

• Is petrolatum more like a free‑flowing liquid fuel, a gas, or a semi‑solid/waxy material, and how does that affect spread of burning liquid? • Which agents are best at smothering and preventing reignition on the surface of thick, oily products? • In an open area, which agents are likely to blow away or disperse quickly, reducing their effectiveness?

✅ Before You Answer

• Confirm how the Chemical Data Guide classifies petrolatum (e.g., oily/semi‑solid petroleum product). • Compare which listed agents are recommended for surface fires of petroleum products rather than electrical or confined-space fires. • Think about which agent can form a stable, lasting blanket over the burning material in wind or open-deck conditions.
