As compared to carbon dioxide, dry chemical has which advantage?
AI Explanation
The correct answer is C) Greater range.
Dry chemical fire extinguishers have a greater effective range compared to carbon dioxide (CO2) extinguishers. Dry chemical agents are propelled using compressed gas, allowing them to be projected further from the extinguisher. In contrast, CO2 extinguishers rely on the expansion of the liquid CO2 to expel the agent, resulting in a shorter effective range.
The greater range of dry chemical extinguishers is an advantage as it allows the user to direct the extinguishing agent from a safer distance, particularly in situations where the fire is located in a hard-to-reach area.
The other options are incorrect because:
A) Dry chemical is not specifically more effective on metal fires compared to CO2.
B) Dry chemical is not necessarily cleaner than CO2, as both can leave residue.
D) Dry chemical does not have a greater cooling effect than CO2.
