🔍 Key Concepts

• Epoxy coating manufacturer limitations on temperature and pressure • Effect of high temperature and high-pressure water on softening or eroding tank coatings • Typical maximum safe wash water ranges used to protect epoxy linings on cargo tanks

💭 Think About

• Which combination of temperature and pressure seems most likely to protect an epoxy coating rather than risk damaging it? • Compare the options: which ones look more like extreme cleaning conditions versus gentle but effective cleaning conditions? • If epoxy can be softened by heat, would you expect wash water closer to boiling point or well below it for routine tank washing?

✅ Before You Answer

• Eliminate any option where temperature is near 212°F (boiling), as this often risks coating damage. • Consider whether very high pressure (hundreds of psi) is normally recommended directly on protective coatings. • Ask: for long-term tank integrity, which choice is most consistent with conservative limits on both temperature and pressure?
