A. NON-POTABLE GRAY WATER - UNSAFE WATER
B. DO NOT TOUCH - UNSAFE WATER
C. CAUTION - BIOHAZARD
D. CAUTION - NON-POTABLE GRAY WATER - DO NOT DRINK

Answer 1

Gray water pipes must be labeled "CAUTION - NON-POTABLE GRAY WATER - DO NOT DRINK" to denote that it is unsafe for consumption and to prevent health hazards.

Step-by-step explanation:

Gray water supply piping is required to be clearly labeled "CAUTION - NON-POTABLE GRAY WATER - DO NOT DRINK". Potable water is water that is safe to consume, being free from harmful chemicals and pathogens. On the other hand, gray water is reused water from domestic activities such as laundry and bathing. It is important to label non-potable water sources to prevent the accidental consumption of unsafe water. Proper labeling is crucial in maintaining public health and preventing waterborne diseases, which are a significant risk in areas without access to clean water and proper sanitation. Labeling also serves as a reminder of the challenges faced globally, including water pollution and the effort to provide safe water for drinking and irrigation.

Answer 2

Gray water supply piping is required to be clearly labeled D. CAUTION - NON-POTABLE GRAY WATER - DO NOT DRINK.

Step-by-step explanation:

The correct labeling for gray water supply piping is essential to convey its non-potable nature and prevent confusion. Option D, "CAUTION - NON-POTABLE GRAY WATER - DO NOT DRINK," accurately communicates that the water in these pipes is not suitable for drinking.

Gray water refers to wastewater from non-toilet fixtures such as sinks and showers, which can be recycled for certain purposes but is not meant for consumption. Options A (NON-POTABLE GRAY WATER - UNSAFE WATER), B (DO NOT TOUCH - UNSAFE WATER), and C (CAUTION - BIOHAZARD) do not precisely convey the appropriate information about the nature of the water or its potential risks.

Option D is the answer.
