Storage & Handling

Storage & Handling

Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling STEP-FLOW 4000. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after using the material.

Bulk Storage Information

STEP-FLOW 4000 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. STEP-FLOW 4000 should be stored between 90-110 °F (32-38 °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. Storage under nitrogen will prevent degradation of the product over time.

Workplace Exposure

Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures.
