VI. RECOMMENDED APPLICATION PROCEDURE
1. Application Method: Spray on water around the perimeter of an oil slick using a pressurized backpack sprayer or aerial applicator. 2. Concentration/Application Rate: 6.4 U.S. gallons/mile (or 15L/km). 3. Conditions for Use: SILTECH OP-40 is designed to aid in situ burning of free oil in calm water with drift ice where fire boom would be ineffective. When sprayed on the water around the perimeter of an oil slick, SILTECH OP-40 will concentrate the oil to a thickness suitable for igniting a burn. It works in all water temperatures and salinities and works best with fluid petroleum that has not weathered significantly.
