IV. Special handling and worker precautions for storage and field application
1. Flammability: Non-flammable (DOT: Non-hazardous) 2. Ventilation: Use combination of general dilution ventilation and local exhaust ventilation to keep exposure as low as possible. 3. Skin and eye contact; protective clothing; treatment in case of contact: Prevent skin and eye contact by wearing appropriate personal protective equipment. If eye or skin irritation occurs, flush with plenty of fresh water. Coveralls or other suitable protective garments should be worn with suitable footwear for application and working conditions. Chemical safety goggles or glasses and impervious gloves are recommended. 4.a. Maximum storage temperature: below 120ºF 4.b. Minimum storage temperature: above freezing 4.c. Optimum storage temperature range: 55ºF to 100ºF. Avoid storage in areas of extreme heat or extreme cold. Store in tightly closed containers, and away from children. 4.d. Temperatures of phase separation and chemical changes: Stable

VI. Recommended application procedure
PETROCLEAN™ is effective in bioremediating petroleum contaminated soils and is not designed for use in open waters. There are no limitations to usage within optimum temperature parameters. Application Method: Surficial spraying of PETROCLEAN™ may be applied by any type of liquid delivery system. Soils and gravels can be treated with PETROCLEAN™ using a conventional yard sprayer. Repetition may be needed. PETROCLEAN™ can be applied to secondary containment areas, the key factor in cleaning the contaminated substrate, whether gravel or soil, is residence time for the microbes, moisture, and oxygen. Subsurface application can vary by location. Soil type becomes a contingent factor in dilution rates and method of application. When bioremediating soils, cleaning the contaminated substrate, whether gravel or soil, is affected by residence time for the microbes, moisture, and oxygen. For in-situ soils, mix PETROCLEAN™ with water to the desired concentration and dispense inoculated fluids in the subsurface, adjacent infrastructure, and the surface. For ex-situ soils and longer term bioremediation projects, additional applications of nutrients and oxygen releasing compounds may be required to maintain or boost microbial activity. Concentration/Application Rate: Rates will vary based upon the type of soil and amount of petroleum spilled, the extent of weathering, and other site-specific conditions, including soil profiles, proximity to surface waters and wells. Heavy petroleum compounds such as crude oil and bunker fuel, with a higher proportion of complex aliphatics, will require a higher concentration of PETROCLEAN™ than lighter petroleum compounds such as gasoline. Hydrocarbon types: PETROCLEAN™ can be applied on any hydrocarbon compound (including crude, diesel, gasoline, aviation fuel, bunker fuels, etc.) found in soils. Most frequent applications include any petroleum contamination around AST’s and USTs and containment pits requiring rehabilitation. Concentration Rate: on heavy oils, apply PETROCLEAN™ directly on the spill area following absorption of free product, utilize a 1:10 dilution ratio (product to water). Lighter oils will require a 1:30 (product to water) dilution ratio. Conditions for Use: Bioremediation slows at temperatures below 40ºF. No limitations as to usage within optimum temperature parameters have been observed. Monitoring of dissolved oxygen levels is recommended. If needed, a mechanical aeration device should be deployed or the use of Oxygen Releasing Compounds (ORC) should be encouraged to maintain dissolved oxygen levels above 3 mg/L. Additional nutrients may be required to increase microbial activity over time if intrinsic nutrients are depleted. The application of 10% nitrogen, 10% phosphorus, and 10% potassium fertilizer can be used in-situ or ex-situ as situations warrant to boost microbial activity and enhance co-metabolic digestion of petroleum. Prevent spill run-off from entering surface water bodies. Eliminate all source of ignition. Dispose of used absorbent materials according to all local, regional, and federal regulations.
