February, 2001 - Nitrous Oxide Security

Nitrous Oxide abuse results in several fatalities every year. Those who use the gas illegitimately for recreational use often take the mistaken view that since it is frequently administered by dentists, it cannot be harmful. They fail to realize that when administered for anesthesia purposes, it is blended with oxygen. However, pure nitrous oxide will cause asphyxiation. Within seconds, an individual can stop breathing because of the depression of the central nervous system caused by the N2O, and by the lower oxygen content that occurs as pure N2O displaces oxygen in the user's lungs. A person who is rendered unconscious by nitrous oxide is likely to stop breathing within a few seconds as a result of a depressed central nervous system--brain, brain stem, and spinal cord.

It is recommended that legitimate users:

1. Minimize theft and indiscriminate use of nitrous oxide by storing containers and utilization equipment in a secured area subject to removal by authorized personnel only
   
   
2. Keep an inventory of bulk product and or containers (both full and empty) and investigate any discrepancies
   
   
3. Report any thefts promptly to the police and the shipper
   
   
4. Use denatured (e.g., rendered unfit for human consumption) nitrous oxide, if required, for enhancing performance of internal combustion engines, so as to deter abuse
   
   
5. Alert employees to the dangers of nitrous oxide abuse and train them on the special security measures they should take to prevent its theft
   
   
6. Provide employees with a current MSDS and any additional instructions for proper use and safe handling practices.
