Distillation Column Decontamination and Dismantlement Activities Activity Hazard Analysis (AHA)

Decommissioning fractionating columns used in large scale industrial distillations can present risks to workers. Technicians may be working with volatile organic compounds and are at risk of chemical exposure. In addition to working with hazardous materials, technicians may be required to operate heavy equipment. Thus, all operations should be performed with safety in mind. The Distillation Column Decontamination and Dismantlement Activities Activity Hazard Analysis (AHA) app outlines specific procedures for decommissioning fractionating columns including guidelines for ensuring the health and safety of technicians engaged in this type of work. The app outlines all work activities necessary for the decommissioning, the potential health and safety hazards, and control measures to mitigate risks. For example, if a worker or contractor utilizes high-pressure water washing equipment to decontaminate the column, they may be exposed to environmental and chemical hazards and should use appropriate personal protective equipment. This app thoroughly outlines the roles and responsibilities of each individual involved in decommissioning a distillation column and is an excellent addition to the safety plan for a closure project.
