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
