With the development of modern industry, some high-end chemicals are becoming more and more important in my life, but we usually pay little attention to the impact of these chemicals on our body and environment. Phosgene is such a chemical substance, it is a colorless gas with a pungent smell, density, soluble in water. Phosgene has these properties, also makes it has the following hazards and risks.

First, phosgene is a carcinogen. The decomposition of phosgene produces nitrogen dioxide and nitric oxide, which will damage human cells and directly lead to lung cancer, nasopharyngeal cancer and other cancers. Therefore, people with long-term exposure to phosgene should pay special attention to personal protection.

Secondly, phosgene is strongly irritating. Phosgene is very irritating, can damage the conjunctiva and throat mucosa, and cause serious respiratory diseases. Phosgene exposure may cause transient incapacity of the respiratory system and is one of the dangerous irritant substances. If exposed to phosgene for a long time, it will have a serious impact on the health of professional workers.

third, phosgene is a flammable substance. Phosgene is mixed in the air to form a flammable mixture of gases, which can explode with fireworks, fire and other fire sources, resulting in fire. If you use a phosgene lamp in your garage, you must pay attention to the safe use of the lamp.

In order to prevent the harm caused by phosgene, we should take the following preventive measures:

1. Avoid using phosgene lamps in confined spaces, and ensure the circulation of indoor air.

2. Protective glasses and masks should be worn to prevent phosgene from irritating the eyes and respiratory tract.

3, keep the safe distance between phosgene lamp and other flammable materials to prevent explosion or fire.

4, if necessary, should be equipped with independent ventilation equipment or equipment with protective function to ensure the safety of professional workers.

In conclusion, phosgene is a very dangerous chemical that causes great damage to humans and the environment. We should strengthen the research and management of phosgene, realize the harmfulness of phosgene, and strengthen safety measures to prevent any accidents.
