Signal Word: WARNING (or DANGER depending on concentration of phosphonates) Nalco TRAC 115 — MSDS (Safety Data Sheet)
Previously unlisted hazards: The new MSDS includes specific information on respiratory sensitization and hazardous decomposition products (e.g., phosphine gas when overheated), which were missing in older versions.
The SDS gives a PEL (Permissible Exposure Limit) for Sodium Nitrite: Usually 1 mg/m3 (respirable) or "none established" for the blend. But pay attention to the Skin notation. GHS05 (Corrosion – for eye damage) GHS07 (Exclamation
Nitrite is absorbed through intact skin. In high temperature systems (>120°F), dermal absorption rates skyrocket. If you are wearing a Tyvek suit but cloth gloves, you are getting a systemic dose.
Best Practice: The SDS calls for butyl rubber or nitrile gloves (>0.11mm thickness). Do not use latex.
New reaction warning: Contact with nitrates or nitrites (common in some fertilizer plants) may form nitrosamines – a potential carcinogen.
