Storage & Handling

Storage & Handling
  • Normal safety precautions (i.e. gloves and safety goggles) should be employed when handling STEPOSOL ME. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material. Product temperatures over 130°F (54°C) are not recommended.
  • Being derived from soybean oil, STEPOSOL ME contains polyunsaturated fatty acid methyl ester that can spontaneously combust. Oily rags, presenting a large surface area for air contact, should be washed out or stored where there can be no fire hazard.
  • Storage Information: STEPOSOL ME can be stored in vessels of carbon steel, but 316 or 304 stainless steel is preferred. Tanks should be closed with venting through a gooseneck vent. The methyl ester should be stored between 50-110°F (10-43°C). External steam panel coils can be used if heating is required. Pumps, pipes, and transfer lines can be carbon steel, but 316 or 304 stainless steel is preferred. Rubber hoses are not recommended for extended use as methyl esters attack rubber. Drums should be stored in sealed containers at a temperature of 50-110°F (10-43°C). Storage under nitrogen will prevent an increase in moisture in the product over time.
