Objective. Students will describe the steps of Hands-Only CPR, the operation of an AED, and first-aid response to the most common IT-workplace injuries — electric shock, repetitive-strain injury, and slip/fall — following American Red Cross or American Heart Association guidelines.
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.
IT professionals spend long hours around powered equipment — servers, UPS units, power distribution panels, and workstations. While cybersecurity work is largely desk-based, the physical environment creates real hazards: electric shock from faulty equipment, repetitive-strain injuries (RSIs) from extended keyboard and mouse use, and slip/fall incidents in cable-cluttered data centers. Knowing how to respond quickly and correctly can save a life or prevent a minor injury from becoming a serious one.
First-aid response is part of a broader workplace safety culture that supports every credential you will earn. Employers governed by OSHA regulations are required to ensure that employees have access to prompt first-aid treatment. Knowing the basics does not replace professional medical care, but the few minutes before emergency services arrive are often the most critical.
Always call 911 (or your facility's emergency number) first, or direct a bystander to call, before beginning any first-aid procedure.
Hands-Only CPR, endorsed by both the American Heart Association (AHA) and the American Red Cross, is the recommended approach for bystanders who witness a sudden cardiac arrest in an adult. It removes the barrier of mouth-to-mouth breathing while still delivering life-saving chest compressions.
Steps in sequence:
1. Confirm the scene is safe. Do not approach if electrical hazards, fire, or structural danger are present.
2. Check for responsiveness. Tap the person's shoulders firmly and shout, "Are you okay?"
3. Call 911 (or have a bystander call). If alone, call before starting compressions.
4. Send someone for the AED. Time to defibrillation is critical.
5. Position your hands. Place the heel of one hand on the center of the chest (lower half of the sternum), then place the other hand on top and interlace fingers.
6. Compress hard and fast. Push down at least 2 inches; aim for a rate of 100–120 compressions per minute. The AHA suggests the beat of the song "Stayin' Alive" as a memory aid.
7. Allow full chest recoil between compressions — do not lean on the chest.
8. Continue without interruption until an AED is ready to use, the person shows obvious signs of life, or trained emergency responders take over.
Wear disposable gloves whenever available to maintain hygiene during manikin practice or actual response.
An AED is a portable device that analyzes heart rhythm and, if needed, delivers an electrical shock to restore a normal rhythm. Modern AEDs provide step-by-step voice and visual prompts — follow them exactly.
General sequence (all AED models follow this pattern):
1. Power on — open the lid or press the power button.
2. Attach pads — place one pad on the upper right chest below the collarbone; place the other on the lower left side below the armpit. Use the illustrated diagrams on the pads as your guide.
3. Plug in the connector if the pads are not pre-connected.
4. Clear the patient — ensure no one is touching the person while the AED analyzes rhythm.
5. Follow the prompt — if a shock is advised, announce "Clear!" loudly, visually confirm everyone is clear, then press the shock button.
6. Resume CPR immediately after the shock and follow subsequent AED prompts.
Do not use an AED if the patient is in standing water or lying in a puddle, or if the pads cannot be placed properly (e.g., severe chest burns — defer to arriving EMS).
Server rooms and data centers carry live electrical circuits. If a colleague receives an electric shock:
1. Do not touch the person until you confirm the power source is de-energized. Use the equipment's power switch, circuit breaker, or UPS shutdown — never use your bare hands to pull someone away from a live source.
2. Call 911. Even a mild shock can cause internal injury or delayed cardiac effects.
3. Keep the patient still and calm. Do not allow them to walk around; lay them down and monitor breathing.
4. Look for entry and exit wounds (burns) and cover them loosely with a clean, dry dressing if available.
5. Document the incident on an OSHA Form 300 (Log of Work-Related Injuries and Illnesses) as required by OSHA recordkeeping rules when the incident meets reporting criteria.
RSIs — such as carpal tunnel syndrome and tendinitis — develop over time from repeated motion. Immediate first aid for an acute flare-up includes rest, applying ice wrapped in a cloth (20 minutes on, 20 minutes off), and elevating the affected limb. Refer the employee to occupational health or a physician. Ergonomic workstation adjustments are the primary preventive measure.
Data centers have cable trays, raised floors, and slick surfaces. If a coworker falls:
1. Do not move them if head, neck, or spinal injury is suspected — call 911 and keep them still.
2. Control any bleeding with direct pressure using a gloved hand and a clean cloth.
3. If the person is conscious and no spinal injury is suspected, help them to a safe position.
4. Complete an incident report per your facility's procedure.
Answer each question, then check it. Nothing is recorded; this is your own practice.
