IV. SPECIAL HANDLING AND WORKER PRECAUTIONS FOR STORAGE AND FIELD APPLICATION
1. Flammability: Non-flammable (DOT: Non-hazardous)
2. Ventilation: No special requirements. In closed spaces, uses dust protective measures.
3. Skin and eye contact; protective clothing; treatment in case of contact: No special equipment or clothing is required; however, goggles and dust mask are recommended. Applying dry powder may cause irritation to membranes. If eye or skin irritation occurs, flush with plenty of water.
4.a. Maximum storage temperature: 120°F continuous
4.b. Minimum storage temperature: 35°F
4.c. Optimum storage temperature range: 40°F to 120°F


V. SHELF LIFE
Minimum 5 years, with proper storage, in original packaging. Freezing does not harm shelf life; however, extreme heat (over 180°F) for long periods of time can shorten shelf life.


VI. RECOMMENDED APPLICATION PROCEDURE
1. Application Method: Apply DRYLET™ MB BIOREMEDIATION directly to oil contamination. DRYLET™ MB BIOREMEDIATION may be applied by the usual methods of aerial or manual broadcast spreading. For smaller spills, manual broadcast will deliver the best results. Larger spills in open water, marsh, wetlands, or estuary areas should be treated by aerial powder dusting or dusting with mechanical powder pumps.
2. Concentration/Application Rate: Apply DRYLET™ MB BIOREMEDIATION directly on the spill. Apply 0.4 pounds of product per cubic yard of soil, or 50 pounds per acre of open water slick. In marsh, wetlands, and estuaries application rates may be up to 75 pounds per acre depending on the oil type and contamination level.
3. Conditions for Use: Water salinity: can be used in fresh or salt water. pH: 4 to 11.5. Temperature: 32°F – 120°F. Water Temperature: 35°F - 170°F. Nutrient Requirements: Nutrients are included with the product. However, for longer term project, additional nutrients may be added to increase microbial activity. Types and Ages of Contamination: For use on organic and hydrocarbon-based contamination. Tar like contamination may require mechanically breaking the structure to obtain timely results.
