Exposure to high levels of ammonia can cause serious health effects involving the eyes, lungs, and skin. Miners working with or around ammonia should take caution. Use engineering controls, such as ventilation, and if respirators are in use, ensure that an ammonia-specific filter cartridge is used.
Ammonia at Mine Sites
Ammonia is used on mine sites for chemical processing, refrigeration systems, emissions, and as a neutralizing agent. Exposure can occur due to equipment malfunctions, leaks, chemical mixing or improper handling. Ensure proper ventilation in mines where ammonia is naturally occurring.
