You have two grades of bitumen. Grade A has a flash point of 180°C and a fire point of 200°C. Grade B has a flash point of 220°C and a fire point of 230°C. Evaluate the safety implications of using each grade in high-temperature regions.
Consider both the flash and fire points in preventative terms.
During a routine check, a bitumen sample is found with an unexpectedly low flash point. Discuss potential causes of this anomaly and the actions that should be taken.
Think about what could alter chemical properties.
