Top 10 Questions for Carbon Cleaner Interview

1. Describe the different types of carbon cleaning methods and their advantages and disadvantages.

• Chemical Cleaning: Involves using a chemical solution to dissolve carbon deposits. Advantages include being less abrasive than other methods, but it can be time-consuming and may not remove all deposits.
• Dry Ice Blasting: Utilizes frozen carbon dioxide pellets to blast away carbon deposits. Advantages include being non-abrasive and environmentally friendly, but it can be more expensive than other methods.
• Walnut Shell Blasting: Employs crushed walnut shells to remove carbon deposits. Advantages include being less abrasive and biodegradable, but it may not be as effective as other methods.
• Laser Carbon Cleaning: Uses a high-powered laser to vaporize carbon deposits. Advantages include being precise and efficient, but it can be more expensive than other methods.

2. Explain the safety precautions that must be taken when performing carbon cleaning.

General Safety

• Wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and a respirator.
• Ensure adequate ventilation in the work area.
• Follow all manufacturer’s instructions and safety guidelines.

Chemical Safety
