It is safe to use near personnel in a confined space.
B
It displaces the oxygen in the air.
C
It cannot be seen.
D
It cannot be smelled.
AI Explanation
The correct answer is A) It is safe to use near personnel in a confined space. This statement is false because carbon dioxide is an asphyxiant gas, meaning it displaces oxygen in the air and can lead to unconsciousness and even death if used in a confined space. Carbon dioxide is not safe to use near personnel in a confined space, as it can quickly reduce the oxygen content in the air and cause suffocation. The other statements are true - carbon dioxide displaces oxygen, it is colorless and odorless, and these properties make it particularly dangerous in confined spaces where ventilation may be limited.
