Learning content is not a substitute for controlled engineering procedures.
Use academy material to build understanding, then verify actual work against current approved technical and safety requirements.

Educational content
Sajjad's Engineering Academy provides learning material for education and professional development. The website does not provide site-specific authorization to perform engineering work.
Controlled documents take priority
For real work, the latest approved OEM manual, drawings, specifications, site SOPs, method statements, permit-to-work requirements, LOTO procedures, risk assessments and competent-person instructions take priority over academy learning material.
Hazardous work
Do not use website content as the sole basis for work involving live electrical systems, pressure systems, refrigerants, steam, chemicals, confined spaces, work at height, rotating machinery or other hazardous activities. Required training, authorization, isolation and supervision must be in place.
Equipment differences
Machines and systems may differ by model, revision, software version, configuration and site modification. Verify model-specific requirements before troubleshooting, adjusting, dismantling or replacing components.
Results and outcomes
No learning page can guarantee a particular troubleshooting, safety, energy-saving or maintenance outcome. Good engineering decisions require accurate measurements, current documentation and competent assessment of the actual system.
Third-party references
References to manufacturers, equipment families or technical documents are for learning and identification. Trademarks and third-party materials remain the property of their respective owners.
