Objective. Students will demonstrate hands-only CPR and two-rescuer CPR with AED operation on a training manikin, and complete a simulated OSHA-compliant incident report for an electrical shock scenario.
This lesson, its worked examples and its practice questions has not yet been verified by an industry-certified professional or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Data centers run on high-voltage power distribution units (PDUs), uninterruptible power supplies (UPS), and dense electrical infrastructure. Electrical shock, arc flash, and other life-threatening emergencies can occur even in well-maintained facilities. A technician who knows exactly what to do in the first minutes of an emergency can mean the difference between life and death. This lesson covers hands-only CPR, two-rescuer CPR with a bag-valve mask (BVM), AED operation, and OSHA-required incident reporting — all skills you will practice today on manikins and in a tabletop scenario.
Before you approach any victim in a data center, confirm the scene is safe. If a coworker has received an electrical shock, do not touch them while they are still in contact with the energy source — you will become a victim too. The correct sequence is:
1. Call out to alert others and identify the hazard.
2. De-energize the circuit if you can do so safely and quickly (use an emergency power-off button or notify the electrical team).
3. Confirm the scene is safe before approaching.
4. Call 911 (or direct someone specific to call).
5. Begin CPR if the victim is unresponsive and not breathing normally.
6. Deploy the AED as soon as one is available.
Lockout/tagout (LOTO) procedures protect workers during planned maintenance, but in an unplanned emergency your first tool is the emergency power-off (EPO) or circuit breaker — never put yourself at risk to be a hero.
For adult victims of sudden cardiac arrest witnessed by a bystander, hands-only CPR (chest compressions without rescue breaths) is effective and recommended by the American Heart Association (AHA) when you are not trained in or not comfortable with rescue breaths.
Technique:
In a data center environment, two trained responders are often available. Two-rescuer CPR improves quality because one person focuses on compressions while the other manages the airway.
Automatic External Defibrillators (AEDs) analyze heart rhythm and deliver a shock if needed. AED trainers replicate the full process safely. The universal steps:
1. Power on the AED (open the lid or press the power button — most units talk you through the process).
2. Attach pads — one pad to the upper right chest (below the collarbone), one pad to the lower left side of the chest (below the armpit). Follow the diagrams on the pads.
3. Clear the victim — announce "Clear!" and ensure nobody is touching the victim while the AED analyzes rhythm.
4. Deliver shock if advised — press the shock button while everyone remains clear.
5. Resume CPR immediately after the shock, beginning with compressions.
6. Follow AED prompts continuously until EMS arrives and takes over.
Do not place pads over a pacemaker implant site or medication patch. Dry the chest if wet.
OSHA requires employers to record and, in some cases, report work-related injuries and illnesses. As a data center technician, you may be the first person to document what happened.
Key forms:
Recordable criteria: An incident is OSHA-recordable if it results in days away from work, restricted duty, transfer to another job, medical treatment beyond first aid, loss of consciousness, or diagnosis of a significant injury or illness by a healthcare professional.
Reporting timeline: For fatalities or incidents resulting in in-patient hospitalization of three or more employees, employers must notify OSHA within 8 hours. Amputations and losses of an eye must be reported within 24 hours. Routine recordable incidents are logged but do not require immediate OSHA notification.
When completing the 300 Log, enter the employee's name (unless privacy case applies), job title, date, location, description of injury, and outcome. Complete this within 7 calendar days of learning of the recordable incident.
Answer each question, then check it. Nothing is recorded; this is your own practice.
