The operator must be aware of the flash point (temperature at which ignition could occur) of whatever type of asphalt binder is being used. It is his responsibility to ensure that all necessary safety precautions are taken, but this can never be assumed. The flash point is especially critical with cutback asphalts. As an example, RC-250 has a flash point of 80°F. Standard Specifications Item 300.3 recommend that RC-250 be applied at temperatures between 125°F and 180°F. The maximum allowable temperature for application and storage is 200°F. With this type of asphalt, you are well into the dangerous range any time that you work with it.

There is also danger around the heater and storage unit, especially if using asphalt cement. Storage tanks, pipes, and valves are extremely hot. Adequate safety precautions should be taken to ensure that any part that might be touched is insulated.

Extreme care must be taken when obtaining a sample of asphalt cement. Very hot asphalt cement (350°F) can easily splatter. Proper safety equipment and clothing should be worn.
