Question 3

Passage: 'Cooling water flow must be maintained at a minimum of 200 gallons per minute to prevent equipment overheating. Flow rates between 200 and 250 GPM are considered normal. Rates above 250 GPM indicate a possible valve malfunction and should be investigated.' A flow rate of 230 GPM is best described as:

Accepted Answer

Within the normal operating range

Answer

The passage defines normal flow as between 200 and 250 GPM, and 230 GPM falls within that range.

Question 4

Passage: 'Personal protective equipment (PPE) requirements vary by work zone. Zone A requires safety glasses and hard hat. Zone B requires all Zone A equipment plus chemical-resistant gloves. Zone C requires all Zone B equipment plus a face shield and flame-resistant clothing.' Which PPE is required in ALL three zones?

Accepted Answer
