Regulatory & Compliance

Safety & Health

Safety Precautions

Normal safety precautions (e.g., gloves and safety goggles) should be employed when handling MAKON 25R2. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling MAKON® 25R2.

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.

Storage & Handling

Storage and Handling Conditions
  • Non-Bulk Storage Recommendations: MAKON® 25R2 should be stored in closed containers and kept in a cool, dry place away from incompatible materials (see Section 10 of the SDS). If material is frozen, it may be fluidized by warming with a drum heater or in a steam room. Drums should be vented prior to heating to avoid excessive pressure build up.
  • Bulk Storage Recommendations: MAKON® 25R2 should be stored in vessels of 316 stainless steel, but carbon steel is adequate assuming effective moisture exclusion. Elevated storage temperature may be desirable to maintain ease of pumping. Product temperatures over 122°F (50°C) are not recommended be used.
