Disposal method for petroleum waste?

• A. Dump it down the drain
• B. Keep it in a sealed container
• C. In accordance with local procedures and in a environmentally safe manner
• D. Burn it

Answer: (C)

The key idea here is that petroleum waste must be disposed of through approved local procedures that protect people and the environment. Dumping it down the drain can pollute water systems and is typically illegal. Merely keeping it in a sealed container is only temporary storage, not disposal, so it doesn’t actually remove the waste. Burning it on-site poses risks of uncontrolled emissions and air pollution and is usually restricted to controlled facilities. Therefore, the proper approach is to dispose of petroleum waste in accordance with local procedures and in an environmentally safe manner, typically through licensed hazardous-waste disposal services or designated facilities that handle petroleum residues.
