A Class 3 material with an initial boiling point of 22 °C would be in PG: a. I b. II c. III d. None of the above

Understand the Problem

The question is asking for the classification of a Class 3 material based on its initial boiling point of 22 °C within a specific classification framework (indicated by options I, II, III, or none). To solve this, knowledge about the classification criteria for hazardous materials or similar classifications is required.

More Information

Under hazardous materials regulations, PG I includes materials with an initial boiling point less than or equal to 35 °C.

Tips

A common mistake is not recognizing that boiling points below 35 °C typically correspond to PG I.
