In the silent hours of December 27, 2023, a quiet community in Ennore, Chennai, was abruptly disturbed by an unexpected risk. An ammonia gas leak, originating from a sub-sea pipeline linking the industrial sector to the open sea, sent ripples of alarm through the local population.
The quietude of the night in Ennore was broken when a potentially dangerous ammonia gas leak occurred at a fertilizer manufacturing unit on December 27, 2023. This hazardous leak was traced back to a sub-sea pipeline connecting the industrial facility to the sea. The incident, which happened around 11:45 PM, filled the air with an unpleasant stench, prompting immediate action.
The repercussions of this gas leak were felt immediately, with 52 locals, including children, rushed to medical facilities due to breathing difficulties. The surrounding residents reported feeling unwell, experiencing nausea and light-headedness, highlighting the seriousness of the situation. The health authority promptly intervened, mandating a temporary halt to the operation of the affected unit until further investigations are carried out.
Upon noticing an anomaly in the ammonia offloading sub-sea pipeline, the company in question responded promptly by initiating the depressurisation of the pipeline to reduce potential dangers linked to ammonia exposure. The immediate suspension of operations ordered by the health authority further emphasises the severity of the situation and the necessity for a comprehensive probe into the origin of the leak.
Ammonia leaks, even minor ones, carry significant risks. The more susceptible components of cooling systems, such as joints and connection points, can lead to leaks. Moreover, incidents involving vehicles used for materials handling can trigger unexpected ammonia gas emissions. This incident in Ennore serves as a severe warning of the potential hazards tied to industrial activities that involve ammonia.
When faced with an ammonia leak, safety should be the highest priority. For indoor leaks, evacuating the area should be the first step. If the leak is due to household cleaning or chemical products, it’s advised to open windows and doors to allow fresh air to circulate. Leaving the impacted area until the gas has dispersed is vital for personal safety.
In situations where ammonia is leaking into the atmosphere, using a water spray may help to “knock down” the vapour and minimise gas emissions. Covering the nose with a damp towel can also offer some protection against inhaling the gas. These safety precautions are crucial for residents and workers, especially those living or working in areas susceptible to industrial incidents involving ammonia.
