IV. SPECIAL HANDLING AND WORKER PRECAUTIONS FOR STORAGE AND FIELD APPLICATION
1. Flammability:
Non-flammable (DOT: Non-Hazardous).
2. Ventilation:
No special requirements.
3. Skin and eye contact; protective clothing; treatment in case of contact:
No special equipment or clothing required; however, goggles are recommended. If eye or skin irritation occurs flush with plenty of water.
4.a. Maximum storage temperature: 120ºF continuous, 140°F up to 5 days
4.b. Minimum storage temperature: 35ºF
4.c. Optimum storage temperature range: 40 - 120ºF
4.d. Temperatures of phase separations and chemical changes: Stable
V. SHELF LIFE
Unlimited in sealed polydrums of totes (as delivered).
VI. RECOMMENDED APPLICATION PROCEDURE
1. Application Method:
ZI-400 may be applied by the usual method of aerial or boat spraying. For smaller spills a drum pump with sprayer may be used, mixing with water as required depending on the type and viscosity of oil being treated.
2. Concentration/Application Rate:
On heavy oils use ZI-400 directly on the spill, or up to approximately a 1:10 dilution ratio (product:water). Lighter oils will require a 1:10 to 1:30 product to water dilution ratio. Warmer waters (greater than 78°F) and/or good agitation during application will require less product.
3. Conditions for Use:
No limitations as to usage within in optimum temperature parameters (application may be made at or above 35°F, with optimum above 48°F).
