Q: Is Fiberglass Insulation Dangerous? Concerns About Heart Attack Risks

Hello： It can be said that glass wool cannot penetrate the stratum corneum of the skin to enter the bloodstream and cause myocardial infarction leading to a stroke. <br>There is no need for concern, and there are no reported cases in the literature, unless there is a large wound

Will fiberglass cause myocardial infarction?

Hello Doctor, today I was installing wall outlets, and the wall is a lightweight partition filled with soundproofing fiberglass insulation.
After finishing, my hands were covered in fiberglass dust and shards.
I seem to recall my chemistry teacher mentioning that fiberglass should not be handled with bare hands because it is very fine, brittle, and hard.
Additionally, since glass does not dissolve, it can easily penetrate the skin and enter the bloodstream, potentially leading to myocardial infarction or stroke.
The more I think about it, the more anxious I become, as my hands are covered in it and the fibers are so fine that I can't tell if any have penetrated my skin.
Is fiberglass really that dangerous? Thank you.

More Info

Fiberglass insulation, commonly used in construction for its thermal and acoustic properties, has raised concerns regarding health risks, particularly when it comes to skin contact and inhalation. Your apprehension about handling fiberglass insulation is understandable, especially given the potential for irritation and the myths surrounding its dangers.

Firstly, fiberglass is made from fine strands of glass, which can be irritating to the skin, eyes, and respiratory system. When you handle fiberglass insulation, the tiny glass fibers can break off and become airborne, leading to inhalation or skin contact. This can cause skin irritation, resulting in rashes or itching, and respiratory issues if inhaled, such as coughing or throat irritation. However, it is important to clarify that while fiberglass can cause discomfort and irritation, it is not directly linked to severe health risks like heart attacks or strokes.

The concern that fiberglass fibers could enter the bloodstream and cause cardiovascular issues is largely unfounded. Fiberglass fibers are too large to penetrate the skin effectively, and while they can cause irritation, they do not dissolve in the body or circulate in the bloodstream. The primary health risks associated with fiberglass are related to irritation rather than systemic toxicity.

To mitigate any potential risks when working with fiberglass insulation, it is advisable to take certain precautions:
1. Protective Gear: Always wear gloves, long sleeves, and a mask when handling fiberglass insulation. This will help minimize skin contact and reduce inhalation of airborne fibers.

2. Ventilation: Ensure that the area is well-ventilated to disperse any airborne fibers. If possible, work outdoors or in a space with good airflow.

3. Clean Up: After handling fiberglass, wash your hands thoroughly and change your clothes to remove any fibers that may have clung to your skin or clothing.

4. Seek Medical Attention: If you experience persistent irritation, such as a rash or respiratory symptoms, consult a healthcare professional for advice.

In summary, while fiberglass insulation can cause irritation and discomfort, it does not pose a significant risk of serious health issues like heart attacks or strokes. The key is to handle it with care and take appropriate safety measures to protect yourself from irritation. If you have any ongoing concerns about your health after handling fiberglass, it is always best to consult with a medical professional for personalized advice.
