Tankerman · Cargo Properties — Reid Vapor Pressure
A gasoline with a high Reid Vapor Pressure (RVP) requires extra care because it:
- AVaporizes readily, generating more vapor and a greater explosion/venting hazard during handling✓ Correct
- BWill not burn
- CIs denser than water
- DCannot generate static
Explanation
RVP measures a product's volatility at 100°F. High-RVP cargoes (like gasoline) flash off vapor readily, increasing the flammable vapor produced during loading, the load on the venting/vapor-control system, and the static and breathing-loss concerns. Handling and venting must be planned accordingly.
