A reading of 3% on a detector tube is equivalent to how many PPM?

• A. 3,000 PPM
• B. 30,000 PPM
• C. 300 PPM
• D. 30 PPM

Answer: (B)

A reading of 3% on a detector tube can be converted to parts per million (PPM) using the relationship between percentage and PPM. Since 1% is equal to 10,000 PPM, a reading of 3% can be calculated as follows: 3% = 3 x 10,000 PPM = 30,000 PPM. This means that for every one million parts of air, there are 30,000 parts of the substance being measured, which directly corresponds to the percentage reading obtained on the detector tube. Understanding this conversion is crucial for anyone working in environments involving hazardous substances, as it aids in maintaining safety and compliance with health regulations.
