Syncope (Fainting) in the Workplace and Its Importance in Occupational Health

What is Syncope?

Syncope, commonly known as “fainting,” is a brief loss of consciousness caused by a temporary decrease in blood flow to the brain. It usually resolves on its own within a few minutes, but when it occurs in the workplace, it can pose serious risks to the employee and workplace safety.

The Importance of Syncope in the Workplace

Experiencing syncope at work can endanger both the individual's health and workplace safety. In particular:

Sudden loss of consciousness in workers at heights can lead to fatal accidents.
Fainting in workers operating machinery and vehicles can result in serious workplace accidents.
Brief loss of consciousness in workers performing tasks requiring intense concentration puts their teammates at risk.

Possible Causes of Syncope in the Workplace

Working conditions may include factors that increase the risk of syncope:

• Standing for long periods of time
• Working in hot and stuffy environments
• Inadequate fluid and nutrient intake
• Stress, intense anxiety, excessive fatigue
• Cardiac (heart-related) disorders
• Blood pressure or rhythm disorders

Precautions That Can Be Taken in Terms of Occupational Health

Employee Health Screenings: Early detection of heart and blood pressure problems through regular checkups
Training and Awareness: Employees recognizing the signs before fainting (such as dizziness, darkening of vision, cold sweating)
Workplace Environment Adjustments:
Rest breaks for those who stand for long periods
Cooling facilities in hot environments
Encouraging adequate fluid intake
Emergency Procedures: First aid and rapid medical assistance when an employee experiences syncope
Workplace Controls for High-Risk Positions: Closer monitoring of the health status of employees working at heights or operating vehicles or machinery

Syncope is often short-lived and harmless; however, when it occurs in the workplace, it can lead to serious accidents and injuries. Therefore, early diagnosis, regular health checks, training, and appropriate workplace adjustments by occupational physicians and safety experts are crucial for reducing the risk of syncope.

Syncope in the Workplace: Pathophysiology, Risk Factors, and Assessment from an Occupational Health Perspective

Summary

Syncope is a sudden onset, transient loss of consciousness due to a temporary decrease in cerebral perfusion that resolves spontaneously within a short period. Its occurrence in the workplace is important for individual health and can also have critical implications for occupational safety. This article examines the pathophysiology, causes, workplace risks, and preventive approaches to syncope.

Introduction

Syncope accounts for approximately 3–5% of all emergency department visits (Moya et al., 2009). Although its etiology is mostly benign, syncope due to cardiac causes in particular may carry a high risk of mortality. Fainting in the workplace can result in serious occupational accidents such as falls from heights, machinery accidents, or traffic accidents. Therefore, occupational physicians and occupational safety specialists need to be knowledgeable about the assessment and prevention of syncope.

Pathophysiology

Syncope primarily develops as a result of decreased cerebral blood flow. This decrease occurs through three main mechanisms:

• Neurocardiogenic (vasovagal) mechanisms
• Orthostatic hypotension
• Cardiac causes (arrhythmias, structural heart disease)

Syncope Risk Factors in the Workplace

Physical Factors: Prolonged standing, hot environments, inadequate fluid intake.
Psychosocial Factors: Stress, heavy workload, anxiety.
Medical Factors: Hypertension, heart disease, diabetes, medications used.
Work Environment Factors: Working at heights, heavy machinery use, shift work, and sleep irregularities.

Diagnosis and Differential Diagnosis

When evaluating syncope, a detailed medical history, physical examination, and basic laboratory tests should be performed. ECG, echocardiography, and rhythm monitoring (Holter) are important for ruling out cardiac causes. The tilt table test is used in the diagnosis of neurocardiogenic syncope (Shen et al., 2017).

Precautions from an Occupational Health Perspective

• Identification of at-risk individuals through regular employee health screenings.
• Improvement of workplace ergonomics and environmental conditions (temperature, humidity, ventilation).
• Employee training to recognize the signs preceding fainting.
• Establishment of first aid and emergency response procedures.
• More frequent monitoring of employees working in high-risk positions (at heights, behind the wheel).

Syncope is often benign; however, it can lead to serious accidents in the workplace, making a preventive approach crucial. Protecting employee health, developing a culture of workplace safety, and conducting regular health screenings with a multidisciplinary approach are essential.
