Question

3 multiple choice 1 point
what are the three different air systems that process technicians are likely to encounter at a large production facility?
compressed, hot, and frigid air
pure oxygen, concentrated and compressed air
purified, hot, and chilled air
utility, instrument, and breathing air
4 multiple choice 1 point
which air system normally has the least - strict quality requirements?
plant air
oxygen tanks for first aid stations
instrument air
breathing air

Explanation:

For question 3: In large production facilities, process technicians typically interact with three distinct air systems: utility (general plant air for non-precision tasks), instrument (clean, dry air for control instruments), and breathing air (filtered for worker safety).
For question 4: Plant (utility) air is used for general, non-critical tasks like cleaning or powering non-precision tools, so it has the least strict quality standards compared to instrument air (needs precision), breathing air (needs safety purity), and first aid oxygen (medical-grade purity).

Answer:

1. Utility, instrument, and breathing air
2. Plant air
