Summary

On October 21, 2016, a chemical release occurred at the MGPI Processing plant in Atchison, Kansas. MGPI Processing produces distilled spirits and specialty wheat proteins and starches. The release occurred when a chemical delivery truck, owned and operated by Harcros Chemicals, was inadvertently connected to a tank containing incompatible material. The plume generated by the chemical reaction led to a shelter-in-place order for thousands of residents. At least 120 employees and members of the public sought medical attention.

KEY ISSUES:
• DESIGN OF CHEMICAL TRANSFER EQUIPMENT
• AUTOMATED & REMOTE EMERGENCY SHUT-OFFS
• PIPE MARKINGS
• CHEMICAL UNLOADING PROCEDURES
• HUMAN FACTORS
• EMERGENCY PLANNING
