What is the color associated with the health hazard rating for pure ammonia?

The color associated with the health hazard rating for pure ammonia is blue. In the context of hazard identification systems, such as the National Fire Protection Association (NFPA) system or similar color-coded systems, blue signifies health hazards. Ammonia is recognized as a toxic substance that can cause various health effects upon exposure, including irritation to respiratory pathways and potential long-term impacts at high concentrations.

Understanding this color-coding is crucial for ensuring safety in environments where ammonia is used or stored. Proper awareness of these hazards enables workers to take appropriate precautions and use the necessary personal protective equipment (PPE) to minimize health risks.
