🔍 Key Concepts

• Electrostatic hazards during tank washing, especially with water mists inside cargo tanks • Differences between fixed tank washing machines and portable machines (how they are introduced into the tank) • How charged mist and metal equipment together can create an ignition source

💭 Think About

• Which option addresses the condition inside the tank atmosphere after fixed washing has created a water mist? • Before you lower any new metal equipment into a tank, what is the main fire/explosion risk you need to control—on the machine itself, or in the tank atmosphere? • Look at which choices deal with sequence of operations versus those that deal with removing the ignition hazard from the tank.

✅ Before You Answer

• Identify which option directly reduces or removes electrostatically charged mist from the tank atmosphere before portable machines are introduced. • Eliminate any options that mostly talk about the fixed machines, when the next step involves portable machines in areas the fixed machines did not reach. • Check which option reflects standard tanker practice for controlling static electricity before introducing additional equipment into a recently washed tank.
