iskukosketus

Iskukosketus is a term used in Finnish to describe exposure to an electric shock resulting from contact with live electrical parts or equipment. It encompasses direct contact with energized conductors as well as indirect contact through faulty insulation or conductive surfaces. The concept is central in occupational safety and electrical engineering, where it is treated as a hazard that can cause injury or death if not properly managed.

The mechanisms of iskukosketus include direct contact with live parts, indirect contact through conductive paths, and arc-related events such as arc flash or arc blast. Severity depends on factors such as voltage, current, contact duration, current path through the body, moisture, and the presence of insulating barriers or protective equipment. Low- and high-voltage situations both pose risks, and wet conditions or damaged equipment markedly increase the danger.

Effects range from minor burns to severe internal injuries, cardiac arrest, respiratory failure, and unconsciousness. Even when immediate symptoms are not apparent, delayed complications such as cardiac arrhythmias, muscle damage, or neurological effects can occur. In occupational settings, iskukosketus is treated with immediate safety measures to prevent ongoing exposure, followed by medical evaluation and possible long-term monitoring.

Prevention focuses on electrical safety practices: isolation and de-energization of circuits, lockout-tagout procedures, proper guarding, insulation, grounding, and the use of appropriate personal protective equipment. Regular equipment maintenance, risk assessments, and worker training are essential. Safe work distances, non-conductive tools, and adherence to established procedures reduce the likelihood of iskukosketus.

First aid for suspected iskukosketus includes ensuring the area is de-energized before approaching the casualty, calling emergency services, checking responsiveness and breathing, providing CPR if needed, and treating burns with clean, non-adherent dressings. Do not attempt to touch the casualty with wet hands or while standing on a conductive surface. Medical evaluation is advised even after apparent recovery.
