IV. Special handling and worker precautions for storage and field application             
1. Flammability: Non-flammable
2. Ventilation: Move subject to fresh air. If breathing is difficult, obtain medical help.
3. Skin and eye contact; protective clothing; treatment in case of contact: Wash affected skin area with water. Consult physician of irritation persists. Skin irritation will not occur with most users. Flush eyes with a large amount of water for at least 15 minutes. Consult physician if irritation persists. Wear safety glasses and neoprene or rubber gloves during application.
4.a. Maximum storage temperature: 120°F
4.b. Minimum storage temperature: 35°F
4.c. Optimum storage temperature range: 40°F to 120°F
4.d. Temperatures of phase separations and chemical changes: NA. Phase separation will not occur within the storage range. Product should be stored out of direct sunlight unless it is in an Ultraviolet (UV) light resistant container.
V. Shelf life 
2 years in a sealed (unopened) container (tote, drum, pail) as delivered. 1 year in an opened container).
VI. Recommended application procedure

1. Application Method: Apply OSR-10 to oil or contaminant with sprayer, pressure washer, mop, sponge, or brush. Application times will depend on the level of contaminant with a minimum of 10 minutes recommended soak time. The required soak time to remove oil will vary with oil density and degree of weathering. OSR-10 separates the oil from the physical surface to allow the oil to be sprayed off with a water rinse. OSR-10 should be mixed into soil applications and agitated to increase the effectiveness and reduce the application time.

2. Concentration/Application Rate: Dilution ratios for most applications range from 2 to 1 (parts water to parts OSR-10) to 15 to 1 (parts water to parts OSR-10). Dilution ratios are dependent on the contamination level and application with heavier crude oil spills requiring a lower dilution ratio. Rinse with water after usage for residue free surface. Surface cleaning typically requires 5 to 1 or 10 to 1 dilution ratio. These dilution ratios will require 1 gallon of OSR-10 per 300 square feet of surface area. These dilution ratios can be used in many applications including shorelines, rocks, and beaches.

3. Conditions for Use: Salt or fresh water (temperature ranges from 35°F to 120°F). Oil or contaminant can be skimmed from the water or rinsed and captured into collection containers and disposed of per local, state, and federal regulations.
