While 28.56 million vaccines were then being administered daily, only 1.8 per cent of people in low-income countries had received at least a first vaccine by September 2021, according to official reports from national
[email protected]Sulfur hexafluoride SF6 gas hazards. Sulfur hexafluoride (SF6) is colorless, odorless, heavier than air and is not considered as toxic.However it is suffocating at high concentrations (it replaces oxygen) just like inert gases (also called noble gases). Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture.
Get PriceProducts SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).
