3. Skin and eye contact; protective covering; treatment in case of contact: May produce eye irritation in some persons and produce eye damage 24 hours or more after instillation. May cause skin irritation after prolonged or repeated exposure. Avoid skin and clothing contact. If skin contact occurs, immediately wash with large amounts of soap and water (if possible). Remove any contaminated clothing and shoes. Launder before reusing. If irritation persists, seek medical assistance. For areas where contact is likely, wear long sleeve shirt, chemical resistant gloves, and chemical resistant goggles.

4.b. Minimum storage temperature: -40°F
4.c. Optimum storage temperature range: 59°F to 77°F
4.d. Temperatures of phase separations and chemical changes: None
V. SHELF LIFE

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.
