The primary HAZMAT code for propane, widely recognized for its identification during transport, is UN/NA 1978. This four-digit number is crucial for emergency responders and transportation personnel to quickly identify the substance and its associated hazards.
Propane is a highly flammable gas commonly used as a fuel. Due to its hazardous properties, it is strictly regulated during storage, handling, and transportation. The UN/NA number serves as a universal identifier that helps ensure the safe movement of hazardous materials across international borders.
Key Identifiers for Propane
To provide a comprehensive understanding of propane's hazardous material classifications, here's a summary of its key identifiers:
| Identifier Type | Code/Label | Description |
|---|---|---|
| UN/NA Number | 1978 | The unique four-digit identification number for propane under the United Nations (UN) and North American (NA) hazardous materials transport regulations. |
| CAS Number | 74-98-6 | The Chemical Abstracts Service registry number, a unique numerical identifier for chemical substances. |
| DOT Hazard Label | Flammable Gas | The hazard class assigned by the U.S. Department of Transportation, indicating its primary danger. |
Understanding the UN/NA 1978 Code
The UN/NA (United Nations/North America) number, such as 1978 for propane, is a critical component of hazardous material shipping documentation and placarding. When emergency services encounter a spill or incident involving a container marked with "UN 1978," they immediately know they are dealing with propane, allowing them to access specific safety data and emergency response guidelines, often found in resources like the Emergency Response Guidebook (ERG).
This standardized code ensures consistency in communication about hazardous materials globally, reducing confusion and improving response times during incidents.
DOT Hazard Label: Flammable Gas
In addition to its UN/NA code, propane is classified with a DOT Hazard Label of Flammable Gas. This classification, governed by the U.S. Department of Transportation, signifies that propane is capable of igniting easily under normal atmospheric conditions. This hazard label dictates specific packaging, labeling, and transportation requirements to mitigate risks.
Understanding both the unique UN/NA code and the broader hazard class is essential for anyone involved in the handling, storage, or transport of propane, ensuring safety protocols are meticulously followed to prevent accidents. For more detailed information, reliable resources like the CAMEO Chemicals database provide extensive data on chemical hazards and emergency response.
