Question

which of these would increase your risk of carbon monoxide poisoning?

running the car in a closed garage
getting regular inspections
opening the garage door before starting the car
opening the windows while driving

Explanation:

Identify the source of carbon monoxide

Internal combustion engines produce carbon monoxide (\(\text{CO}\)), a colorless, odorless, and highly toxic gas.

Evaluate the risk of enclosed spaces

Running an engine in an enclosed space like a closed garage traps exhaust fumes, rapidly increasing \(\text{CO}\) concentration to lethal levels.

Assess the other options

Regular inspections, opening the garage door, and opening windows while driving all help prevent or reduce the accumulation of toxic exhaust gases.

Answer:

• running the car in a closed garage (Correct answer)
• getting regular inspections
• opening the garage door before starting the car
• opening the windows while driving
