How many pounds of cyanide can be treated during an 8-hour shift?

To determine how many pounds of cyanide can be treated during an 8-hour shift, one must consider industry standards, operational capacity, and safety protocols. The correct choice reflects a realistic and safe capacity that aligns with environmental regulations and equipment limitations.

In many water treatment facilities or processes involving cyanide, treatment capacities are often calculated based on the amount of cyanide that can be effectively managed without exceeding safety limits for workers and the environment. The 10 lbs figure is likely derived from these established guidelines, providing a balance between efficiency and safe handling procedures.

The other figures presented—5 lbs, 15 lbs, and 20 lbs—either underestimate the operational capability or exceed safe treatment protocols, which is critical in hazardous material processing. This emphasizes the importance of adhering to safety standards while ensuring effective treatment within regulated parameters. Therefore, the 10 lbs capacity is sound and aligns with responsible operational practices in settings dealing with toxic substances like cyanide.
