🔍 Key Concepts

• Look at the reference tube and measuring tube and how air is drawn past a lamp and mirrors. • Notice the fan constantly circulating air through the system and the rotary valve/rotary arm sampling from several points. • Think about which listed device would need to continuously compare air samples from different locations for early safety monitoring.

💭 Think About

• Which of the four answer choices would reasonably use optical detection (lamp and mirrors) to sense a change in the density or clarity of air? • Why would a device need both a reference tube and a measuring tube instead of just a single passage? What is being compared? • Which machinery space hazard requires continuously sampling air from multiple points with a rotary valve and fan rather than just measuring exhaust flow or starting air flow at one point?

✅ Before You Answer

• Match the illustration features (fan, rotary valve, optical path with lamp and mirrors) to the most logical function among the choices. • Eliminate any option that normally does not use light and mirrors to operate. • Ask yourself which system must operate continuously while the main engine runs to detect a dangerous condition early.
