Safety Officer here...HELIUM WARNING
I have had a bottle of Helium to compliment my pre WW2 era Miller HeliArc since 1972...
Everyone has seen the effects on the voice of people taking in Helium and speaking.. Only THIS week did I learn that Welding Helium is DIFFERENT from the Helium one buys to blow up balloons .... Welding Helium is just Helium. Balloon Helium has 18-20 Percent OXYGEN.... This is because our bodies need some oxygen to stimulate the production of CO2 to exhale.... playing around and sucking in WELDING HELIUM can " STALL " the lungs and kill you ..... it cuts off the signal to the body to do what it is supposed to do to keep us alive...
