What are the risks of PVC outdoor armchairs releasing toxins in extreme heat?

PVC outdoor armchairs are popular for their affordability and durability, but they can pose health risks in extreme heat. When exposed to high temperatures, PVC (polyvinyl chloride) may release toxic chemicals such as phthalates and volatile organic compounds (VOCs). These substances can off-gas into the air, potentially causing respiratory irritation, headaches, or long-term health effects with prolonged exposure.

The risk increases in direct sunlight or during heatwaves, as the material softens and breaks down more easily. Children and pets are particularly vulnerable due to their smaller size and closer proximity to the furniture. To minimize risks, consider using PVC-free alternatives or placing chairs in shaded areas during peak heat. Regular cleaning and avoiding prolonged sun exposure can also help reduce toxin release. Always check for certifications like GREENGUARD when purchasing outdoor furniture to ensure lower chemical emissions.
