Calcium lime is white, if it contains impurities, it will appear gray or yellowish, because it has hygroscopicity, so it is often used as a moisture remover, which can not only effectively absorb moisture in the air when it is used as a moisture remover, but also has a certain absorption effect on carbon dioxide, so in the test often use lime calcium as a detector for carbon dioxide, calcium lime will generate a lot of heat when reacting, let's take a look at what factors need to be paid attention to when using.
1. Leakage: Isolate the leaking pollution area and restrict access. It is recommended that emergency personnel wear self-priming filter dust masks and anti-acid and alkali overalls. Do not come into direct contact with the spill. 1. Small leakage: Avoid dust and use a clean shovel to collect in a dry, clean, covered container. 2. A large amount of leakage: spray water controls dust and protects personnel.
2. Health hazards: Calcium lime is an alkaline oxide, which can produce calcium hydroxide and release a lot of heat after reacting with water in the human body, which has irritating and corrosive effects, so avoid contact with the skin when using it.
3. Hazardous characteristics: Calcium lime can react more violently with acids and has strong corrosiveness.
When using calcium lime, it is recommended that operators wear filtered dust masks and gloves in addition to wearing work clothes, and pay attention to protecting their body and eyes and other exposed skin from contaminating the item.
