What are the three things to remember of processed safety?

• A. Keep It In The Pipe, Eliminate Ignition Source, Minimize Fuel Air Mixture
• B. Keep It In The Pipe, Eliminate Ignition Source Only
• C. Minimize Fuel Air Mixture Only
• D. Eliminate Ignition Source, Keep It In The Pipe

Answer: (A)

The key idea is covering the three safeguards that prevent a process release from turning into a fire or explosion: containment, ignition control, and fuel-air control. The best answer includes all three: Keep It In The Pipe, Eliminate Ignition Source, and Minimize Fuel Air Mixture. Keeping the material inside the pipe reduces the chance of a release entirely. Eliminating ignition sources lowers the risk that any release could ignite if it escapes. Minimizing the fuel-air mixture reduces the possibility that a leak reaches flammable concentrations in the first place. The other choices miss one or more of these essential protections, so they don’t provide the full safety approach.
