What are the hazards of SF₆ gas to the human body?

Under normal circumstances, SF₆ refers to sulfur hexafluoride, which can pose various health hazards to humans, including eye irritation, allergic reactions, risk of suffocation, effects on the central nervous system, and impacts on the cardiovascular system. A detailed analysis is as follows:

1. Eye Irritation

Contact with sulfur hexafluoride gas or liquid may cause skin burns and eye irritation, leading to discomfort symptoms such as redness and pain.

2. Allergic Reactions

If a patient is allergic to sulfur hexafluoride, inhalation may trigger an allergic reaction, manifesting as skin erythema, bradycardia, hypotension, or even anaphylactic shock.

3. Risk of Suffocation

Sulfur hexafluoride is a high-density gas; if leaked in a confined space, it may displace oxygen and create a risk of suffocation.

4. Central Nervous System Effects

Prolonged exposure to high concentrations of sulfur hexafluoride may impair the central nervous system, causing symptoms such as headache, dizziness, and difficulty concentrating.

5. Cardiovascular System Impacts

High concentrations of sulfur hexafluoride may adversely affect the cardiovascular system, resulting in increased heart rate and elevated blood pressure.

If a patient develops any discomfort symptoms, it is recommended to seek timely medical attention at a hospital to avoid delaying treatment.
