            Mr. Haugen is very correct and I may have missed something in all of these emails that have been flying through, but a show of hands probably will not suffice. I have dealt with this sort of thing before at an environmental testing lab I worked for.

            Paul, you need to find the instruction which outlines the rules / guidelines for this sort of thing for your territory / country and if the rules say you do not have to, then go to the OHS person and point it out. If he will not go by the information you have researched, then take it to the next person above.

            If that fails, put in a purchase order for everything he wants and attach the documentation you may have found that says it is not needed. If management approves the purchase, then it will not hurt to put it in place and hold a 15 minute training session prior to the start of work on each shift.

            Now if management denies the purchase, then it is out of your hands. You tried to do what OHS wanted, but it was denied and it is over with.

Here is my vote:


Standby medical grade oxygen is NOT required for ANY experiments involving cyanides salts.  Gaseous HCN is formed only at low pH.  A properly used hood, PPE, hazard communication, and chemical hygiene practices are sufficient.  A neutralization solution of sodium bicarbonate may be "good practice" in the event of an incident.

Dear all,


Can I ask for a quick show of hands. We have a new OHS consultant who a bit hung up on the immediate availablity of medical oxygen and training in administration of medical oxygen for ANY experiments involving cyanide. To the extent that no work should commence until this is in place.

Is this what happens elsewhere? Does it seem a bit oveboard? Is it a 'control' as such, or just a nice thing to have. We are 5 mins away from a major hospital.


Thanks in advance, Paul
