IV. SPECIAL HANDLING AND WORKER PRECAUTIONS FOR STORAGE AND FIELD APPLICATION

1. Flammability:
IMO-Flammable (water based); DOT – Flammable
2. Ventilation:
If used outdoors, mechanical ventilation is not expected to be necessary. If used indoors, mechanical ventilation should be employed. If a risk assessment concludes respiratory protection is warranted use supplied air or air-purifying respirators in compliance with applicable regulatory requirements.
3. Skin and eye contact; protective clothing; treatment in case of contact:
Avoid eye contact. In case of eye contact, immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical attention immediately. Avoid contact with skin and clothing. In case of skin contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing and clean shoes thoroughly before reuse. Get medical attention. Wear chemical and safety goggles, chemical resistant gloves and long sleeves to prevent eye and skin contact.
4.a. Maximum storage temperature: 150°F
4.b. Minimum storage temperature: 10°F
4.c. Optimum storage temperature range: 32 to 96°F
4.d. Temperatures of phase separations and chemical changes: None.

V. SHELF LIFE

The shelf life of unopened drums of SUPERSPERSE™ WAO2500 DISPERSANT (WA02500) is 12 months. Material older than 12 months may still be viable and should be mixed well and then inspected to confirm it is within specifications and suitable for use.

VI. RECOMMENDED APPLICATION PROCEDURE

1. Application Method: The application of WAO2500 is done most effectively by spray type applications. Agitation is necessary and the amount of agitation depends upon the nature of the oil and the thickness of the oil layer to be dispersed. In light oil sheens, only the normal agitation of the water may be necessary, violent agitation is not necessary for controlling crude oil spills. The following method can be used for application:

Hand held spraying equipment – 2 to 5 percent dilution. Do not atomize the dispersant.
Workboat fitted with spray booms – 2 to 5 percent dilution. The spray should be as far forward as possible from boats wake.
Aerial spraying using airplane or helicopter – normally this is done at a height of 40 -70 feet. Effective altitudes depend on weather, wind and other factors. Spray nozzles used in most agriculture application produce sprays that are too small. A simple quarter inch pipe would suffice in most applications. Regardless of the application method, the chemical should be applied in the form of small droplets never as a fog or mist. This minimizes windage losses and also ensures rapid penetration by the surface active agents to the oil/water interface. If applied by air drop methods, usage rates will vary but tend to fall between 1 to 5 US gallons per acre. Dilution ranges from 1:30 to 1:50 could be used.

2. Concentration/Application Rate: WAO2500 can be used as supplied or diluted with water prior to application. The degree of dilution will depend upon the characteristic of the oil and the amount of oil to be controlled. Laboratory tests indicate that as little as 1-4 gallons of WAO2500 will control and disperse a barrel (42 gallons) of light oil.

3. Conditions for Use: The dispersant should be used as early as possible to combat the spill. Wind and weather also dictate the proper effectiveness of the application. Care should be taken to limit overspray conditions. The dispersant would be more efficient if applied before the oil/water mixture forms and emulsion. Use equipment (pipe, hoses, receptacles, etc.) that is resistant to hydrocarbons. Do not spray at high pressure. A course spray is recommended over fine spray. This product can be used across a wide variety of water temperatures. The water temperature should be between 33°F and 96°F. With warmer temperatures less dispersant should be used. This product can be used on a number of hydrocarbon spills. The higher the API gravity of the hydrocarbon the less dispersant is necessary. The salinity of the water will have a slight impact on the performance of the product with a higher salinity needing more dispersant. Older hydrocarbon spills will require more product. The lighter ends of the hydrocarbon spill will evaporate lowering the API gravity of the hydrocarbon. This product should not be used on hydrocarbons that are soluble in water (e.g., alcohols, glycols, water soluble organics).
