Sample IDA - International Detailing Association Practice Questions
Try these questions from our free IDA - International Detailing Association practice tests. The correct answer and an explanation follow each question.
Which gas was released in the Bhopal gas tragedy?
- A. Ethylene
- B. Methyl isocynide
- C. Mustard gas
- D. Potassium isocynide
Answer: B. Methyl isocynide
The correct answer is Methyl isocynide. The Bhopal gas tragedy refers to the catastrophic gas leak incident that occurred in Bhopal, India in 1984. The gas leak was caused by the release of methyl isocyanate (MIC) from a pesticide plant owned by Union Carbide India Limited. MIC is a highly toxic gas that can cause severe respiratory problems, eye irritation, and other health issues. The incident resulted in the death of thousands of people and left many others with long-term health complications.
Why should a detailer avoid using silicone-based dressings on steering wheels?
- A. Silicone causes steering wheels to crack immediately
- B. Silicone dressings make the steering wheel slippery, creating a safety hazard
- C. Silicone is absorbed too quickly by leather to be useful
- D. Silicone changes the color of leather permanently
Answer: B. Silicone dressings make the steering wheel slippery, creating a safety hazard
Silicone-based dressings leave a slick surface on steering wheels, reducing grip and creating a dangerous driving condition.
In maintaining a proper look out the master should take into account all relevant factors except
- A. Visibility
- B. Steering control
- C. Dense traffic
- D. Sound signaling apparatus
Answer: B. Steering control
When maintaining a proper lookout, the master should consider various factors to ensure the safety of the vessel. Visibility is crucial as it allows the master to see any potential hazards or obstacles in the surroundings. Dense traffic is another important factor to consider as it affects the vessel's maneuverability and requires extra caution. Sound signaling apparatus is also relevant as it helps in communication and alerting other vessels. However, steering control is not directly related to maintaining a lookout but rather to maneuvering the vessel. Therefore, it is not a relevant factor to consider in this context.
What does the term 'curb rash' refer to in wheel detailing?
- A. A chemical rash caused by harsh wheel cleaners
- B. Scuffs and scratches on the wheel rim from contact with curbs
- C. Rust spots from road salt on wheel spokes
- D. Brake dust etching into the wheel surface
Answer: B. Scuffs and scratches on the wheel rim from contact with curbs
Curb rash refers to the physical abrasion damage — scuffs, scratches, and gouges — that occurs when the wheel rim contacts a curb.
