NITRIC ACID, RED FUMING Chemical compatibility with O-rings, rubbers, & plastics

Red fuming nitric acid (RFNA) is a highly concentrated and reactive form of nitric acid used primarily as an oxidizer in rocket propellants. It contains dissolved nitrogen dioxide, giving it a characteristic red color and increasing its reactivity. RFNA is also employed in some industrial processes requiring strong oxidizing conditions. Proper handling and storage of red fuming nitric acid are essential to prevent exposure and dangerous chemical reactions. Safety measures should include the use of personal protective equipment, proper ventilation, and adherence to strict regulatory guidelines. Specialized training and protocols are necessary for handling RFNA, ensuring the safety of personnel and the environment. Regular monitoring and maintenance of storage and handling systems ensure the containment and security of this hazardous chemical.
