Summary
This bulletin examines two explosions involving contaminated process materials: heated organic residue in pipework and crude methacrylic acid in a rail tank car. It explains reduced decomposition temperature, corrosion-related contamination and insufficient inhibitor, and recommends material identification, suitable construction materials, cleanliness and adherence to contamination-prevention procedures.
