Railroad Applications Graffiti, Oil and Heavy Grease Removal CGII Site Operating Procedures
- Tend to Corporate Health, Safety, and Environmental requirements.
- Define and isolate the work area(s) from adjacent activity.
- Ensure the rail car is stationary with no potential for movement.
- As heat is a requirement for effective stain removal, ideally schedule any outdoor operations when warmer ambient temperature is planned (~11:00 am to ~1:00 pm). This will allow the work area to be heated so the contaminants are easier to remove.
- Confirm the presence of a hotsie (or equivalent pressurized heating device). Fluids must be in the 125 to 185 Fahrenheit range to effectively remove stains. The hotter the fluid, the easier it is to clean the rail cars.
- Spot treat the staining with sprayed CG-100 and let sit for ~15 – 20 minutes.
- Establish a collection area for the water, chemical, and liberated stains. Consult local environmental requirements. The chemical itself is non-toxic and certified green by Green Seal and Leaping Bunny. However, the contaminants may require collection.
- Slipstream the treating chemical into the hotsie feed stock.
- Recommend volumes of CG-100 are as follows (these volumes can be adjusted based on site-specific observations):
- 3 – 5 pails of CG-100 per hour of individual sprayer.
- Cycle hot treating fluid through the hotsie at maximum rate, heat application, and pressure over the impacted area. Continue working the area until the graffiti or staining is removed. The hotsie pressure tip can be varied in distance from the surface of the rail car to increase the cleaning potential.
- Should the hotsie require abrasive cleaning to assist with the staining or graffiti removal, a pole-connected scrub brush, or equivalent agitator deemed acceptable to the cleaning surface, can be employed.
- Rinse the railcar surface with fresh water and allow the surface to dry.
- Clean up the work area and remove cleaning equipment. Return the rail car to use.
