Why is ammonia (NH₃) considered a toxic refrigerant?
| It is highly irritating to the respiratory tract and toxic if inhaled |
| It does not react with water, which makes it difficult to neutralise |
| It is flammable and can form explosive mixtures with air |
| It is colourless and odourless, so it is difficult to detect |
