Failing to keep supply and distribution containers closed, except when in use, can
result in contamination of the IPA cleaning solution.
2.4.4
Nitrogen
CALIENT recommends using small, disposable cylinders of 99.9% pure compressed nitrogen gas
when cleaning S320 OCS optical fiber connectors. Attention should be given to the information
provided in the cylinder supplier’s Material Safety Data Sheet (MSDS).
Nitrogen cylinders contain gas under high pressure that can cause rapid suffocation
when released. Nitrogen gas acts as a simple asphyxiant by displacing air necessary
for life. If symptoms of asphyxiation occur—such as rapid respiration, loss of muscular
coordination, fatigue, dizziness or nausea—move immediately to fresh air. Also,
never
puncture or incinerate nitrogen cylinders.
2.4.5
Nitrogen Cylinder Precautions
Be sure to observe the following precautions when using an industrial-size compressed nitrogen
gas cylinder:
Keep it from falling over or rolling around to avoid damaging the cylinder valve.
Open the valve a little at a time. If it cannot be opened by hand, return the cylinder to
the supplier. Never use force (e.g., a wrench) when opening or closing a cylinder valve.
Never heat a cylinder containing liquefied gas to increase the gas flow or the required
rate.
Only use connectors designed specifically for compressed-gas cylinders. Never use
intermediate connectors.
Always check the condition of couplings before use.
