Tips: Hazards of Sulphur Hexafluoride (SF6)
Health Risks:
- Asphyxiation: SF6 is a dense gas and can displace oxygen in confined spaces, leading to a risk of asphyxiation. In high concentrations, it can cause dizziness, unconsciousness, and even death due to lack of oxygen.
- Inhalation: Although SF6 is generally considered non-toxic, inhaling high concentrations can cause respiratory issues and potential harm due to oxygen displacement.
Environmental Impact:
- Greenhouse Gas: SF6 is a potent greenhouse gas with a global warming potential (GWP) 23,500 times greater than carbon dioxide (CO2) over a 100-year period. It has a long atmospheric lifetime of about 3,200 years, contributing significantly to global warming and climate change.
- Persistence: SF6 is highly stable and can remain in the atmosphere for thousands of years, making it a long-term environmental pollutant.
Builder in Product TAB
NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc.
You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules.
Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
