A systematic approach can involve:
Identify the problem → Gather information → Check simple causes → Follow procedures → Test appropriately → Document findings → Escalate when necessary
For example, if equipment does not power on, initial checks might involve the power supply, switch and visible connections before assuming that a major internal component has failed.
Troubleshooting should always be performed within the person’s level of competence and authorization.
8. Calibration Awareness
Laboratory professionals should understand why calibration matters for measurement equipment.
They should know:
- Which equipment requires calibration
- Applicable calibration intervals where specified
- Calibration status
- What to do when calibration is overdue
- What to do when equipment fails a required check
- Where calibration records are maintained
Professionals should not assume that an instrument is suitable for use simply because it powers on and appears to operate normally.
9. Quality Control
Quality control involves planned activities used to monitor and control laboratory processes.
Professionals may need to:
- Run controls
- Review results
- Identify deviations
- Record findings
- Take appropriate corrective action
- Escalate problems when required
Quality control helps provide information about whether a process is performing within established requirements.
10. Documentation
If an activity is not properly documented, it may be difficult to demonstrate what happened.
Important records can include:
- Equipment logs
- Maintenance records
- Calibration records
- Test results
- Quality-control records
- Incident reports
- Training records
Documentation should be:
- Accurate
- Timely
- Legible or appropriately digital
- Traceable
- Consistent with applicable procedures
Good documentation supports laboratory quality and accountability.
11. Following Standard Operating Procedures
Standard Operating Procedures, or SOPs, provide documented instructions for performing specific activities.
Professionals should:
- Read applicable SOPs
- Follow approved procedures
- Avoid unauthorized changes
- Report unclear instructions
- Participate in procedure reviews where appropriate
- Use only current approved versions
An SOP is not simply a document to be filed away. It is a practical tool for promoting consistency in laboratory work.
12. Basic Electrical and Instrumentation Awareness

Basic knowledge of:
- Voltage
- Current
- Resistance
- Sensors
- Switches
- Power supplies
- Signals
- Control systems
can help professionals understand equipment behaviour.
However, electrical repair should only be performed by personnel with appropriate competence and authorization.
Understanding equipment does not automatically authorize a person to open, modify or repair it.
13. Digital Skills
Modern laboratories increasingly use computers and digital systems.
Useful skills include:
- Word processing
- Spreadsheets
- Data entry
- File management
- Digital communication
- Data visualization
