During startup of laboratory operations, which of the following should NOT be observed?

• A. Turning On The Hoods, Vents And Exhaust Fans.
• B. Turning The Equipment And Instruments On.
• C. Performing The Analysis Immediately.
• D. Monitoring Operating Parameters.

Answer: (C)

During startup, establishing a safe, controlled environment and confirming all instruments are ready before any data collection is the key idea. Ventilation systems like hoods and exhausts must be on to contain fumes and provide protection, and equipment and instruments need to be powered up and given time to warm up and stabilize. It’s also essential to verify that monitoring parameters, safety interlocks, and calibration checks are functioning before you rely on any readings. Running the analysis right away skips these crucial checks, which can lead to unstable baselines, inaccurate results, and potential safety hazards. So the step to avoid at startup is performing the analysis immediately.
