SECTION 7: HANDLING AND STORAGE

7.1.         Precautions for Safe Handling

Additional Hazards When Processed:  May release poisonous hydrogen sulfide. Hydrogen sulfide is a highly flammable, explosive gas under certain conditions, is toxic, and may be fatal. Gas can accumulate in the headspace of closed containers. Use caution when opening sealed containers. Heating the product or containers can cause thermal decomposition of the product and release hydrogen sulfide. Heating: Correct application temperature is Equiviscous Temperature (EVT) which is the temperature that the asphalt in the mop bucket or mechanical spreader must be at to achieve asphalt consistency or viscosity necessary to ensure that the correct amount of asphalt is applied. Minimize temperature to which product is heated in the kettle to obtain EVT during application in order to maintain quality of installed material and reduce hazard from fumes, hydrogen sulfide, kettle coking and kettle flashes. Maximum kettle temperature should be 50 °F (10 °C) less than flash point to control generation of fumes and avoid possible explosion hazard but the product should never be heated over 500 °F (260 °C) regardless of flashpoint.
Precautions for Safe Handling:  Wash hands and other exposed areas with mild soap and water before eating, drinking or smoking and when leaving work. Avoid prolonged contact with eyes, skin and clothing. Do not handle until all safety precautions have been read and understood. Do not breathe dust or fumes.
Hygiene Measures:  Handle in accordance with good industrial hygiene and safety procedures.

7.2.         Conditions for Safe Storage, Including Any Incompatibilities

Technical Measures:  Deposits (carbonaceous materials and iron sulfides) can develop on the internal walls and roofs of tanks in case of long term storage. These deposits may be pyrophoric and self-ignite in contact with the air. Comply with applicable regulations.
Storage Conditions:  Keep container closed when not in use. Store in a dry, cool place. Keep/Store away from direct sunlight, extremely high or low temperatures and incompatible materials.
Incompatible Products:  Strong oxidizers.

7.3.         Specific End Use(s)
Low slope roofing and waterproofing asphalt.
