What are nitrites, how are they used in VCI and are they hazardous in VCI Packaging?
Nitrites are used in VCI in the form of sodium nitrite. Sodium nitrite has been used as a food preservative for over 100 years. It is found in the bacon you eat for breakfast and the salami you eat for lunch. It has been approved as a food additive for over two-thirds of a century. In fact, over 85% of the sodium nitrite present in our body is produced by our own body. In order to consume the MSDS reported hazardous dosage of sodium nitrite, for a normal VCI at 1.0 g/sq. ft. a person would have to EAT all of the sodium nitrite present in 31 sq. ft. of VCI treated paper. Not only does a person not ingest VCI paper, but rarely comes into contact with it, given the fact that workers should wear gloves to avoid the acidity that our fingerprints give off on the metal surfaces. Similar to most ordinary household chemicals, sodium nitrite is not without risk. It simply must be handled in the same judicious fashion as such ordinary chemicals as household bleach, windshield washer fluid, floor
