Storage & Handling
- Storage & Handling
- Normal safety precautions (e.g., gloves and safety goggles) should be employed when handling STEPGROW NPRO 101. Contact with eyes and prolonged contact with skin should be avoided. Wash hands thoroughly after handling materials. See SDS for more information.
- Bulk Storage Information: Stainless steel and glass fiber-reinforced polyester tanks are recommended. Many oven-cured phenolic and epoxy/phenolic linings may also be used. Ambient temperature of 77°F (25°C) is sufficient to maintain ease of pumping. The recommended storage temperature for STEPGROW NPRO 101 is 50-100°F (10-43°C).
- 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 safety practices should be used to control these exposures. See the SDS for further information.
