# Nitrogen gas: Regulation

The silent asphyxiation risk

Source page: https://www.materialinsights.org/chemicals/nitrogen_gas/regulation/

What this tab covers How it is regulated and what could disrupt supply: hazard classification, rules in the EU, US and India, anti-dumping duties and other trade measures, and supply-risk notes.

#### Hazards

| Classification | UN number | Key risks |
|---|---|---|
| Gas under pressure (compressed or refrigerated liquefied); simple asphyxiant | UN1066 | Asphyxiation in confined spaces is the main cause of nitrogen deaths; liquid causes cold burns and pressure build-up. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | Pressure Equipment Directive; ADR for transport | equipment and transport standards |
| **US** | OSHA confined space rules; DOT hazmat rules | workplace and transport safety |

#### India

| Rule | Effect |
|---|---|
| **Gas Cylinders Rules 2016 and SMPV(U) Rules 2016, licensed by PESO** | storage and transport approvals |
| **Food Safety and Standards (Food Products and Food Additives) Regulations list nitrogen (E941) as a packaging gas (indicative)** | food grade use |

#### Trade measures

- None material

#### Supply risk

No resource risk. Local risks are power supply and plant outages; electronics users need redundant on-site supply.
