Protective liquid ammonia protection

Liquid ammonia is used in a wide range and is used in frozen refrigeration, poultry breeding, chemical fertilizer processing, semiconductor industry, metallurgical industry, and scientific research. However, liquid ammonia is corrosive and easily volatilized due to its unique physical and chemical properties, so the incidence of chemical accidents is high.

Since security accidents caused by liquid ammonia frequently occur, as enterprise managers, we must pay special attention to the safety of employees in our own company. In the case of liquid ammonia protective equipment, it must not be sloppy, but only because of the cost of protective equipment. The following DEHSM brief introduction for liquid ammonia protection equipment for everyone:

1. Instrumentation - Ammonia gas detector

The ammonia gas detector mainly uses the gas sensor in the instrument to detect the concentration of ammonia gas in the environment. The gas sensor then determines whether or not the alarm is given according to the set upper and lower concentration limits. Gas detectors are generally divided into portable and fixed type. They need to be equipped with the actual conditions of their own companies:

a. portable gas detector , is also convenient to detect ammonia concentration on the spot, easy to carry. The brands currently used in the market include Honeywell's Imoulse series, Methian MSA's Eagle series, and BW's GasAlertExtreme series.

b. Stationary gas detectors, of course, are mainly used in the field of liquid ammonia operations and are generally fixed in a corner. It is more suitable for the continuous and long-term stability required by the fixed test in terms of technology and technology. They have to be selected based on the concentration of ammonia on site, and they should also be careful to install them where ammonia gas is most likely to leak. This type of fixed ammonia detector market brand is less, generally imported using MSA DF series of gas detectors.

2. Personal protective equipment

Mainly from the three aspects of respiratory protection, body protection, foot protection

a. Respiratory protection , specific anti-ammonia respiratory protection products are self-priming gas masks, isolated gas masks (air respirator) two categories. Different occasions are used. If the concentration of ammonia gas is relatively small, self-priming gas masks, such as half-masks and full-scale masks, can be used. According to their relatively high concentrations, such as ammonia leakage, they must be equipped with air respirator. Go to the site to plug or other work.

b. physical protection, the previous section DEHSM has initially introduced the common types of liquid ammonia protective clothing on the market , which has been briefly introduced. Liquid ammonia protective clothing If the general enterprises are all workers wearing, then it is not necessary to buy heavy protective clothing, you can use lightweight chemical protective clothing, and then equipped with self-priming gas mask protection, safety factor can also meet the requirements.

c. Foot protection, this one is relatively simple. Because ammonia is corrosive, it must be an anti-chemical boot to protect the foot. It is not recommended to use a low or high-top safety shoe. Anti-chemical boots have a larger area of ​​protection and a high safety factor. General anti-chemical boots prices are not high, the market price is about 100 yuan, the best-selling models are 10120166 anti-chemical boots.

3. Other protective equipment

In addition to the above two major categories, the company itself also needs to configure first aid kits, liquid ammonia plugging tools, and so on. First aid kits are indispensable for each company, and are equipped with some commonly used drugs. They can be used for the treatment of wounds for the first time. It is recommended that DH-Y12 be used for specialized medical kits. The liquid ammonia plugging tool generally uses a strong magnetic plugging. It mainly uses the magnet's strong magnetic force to temporarily block the valve of the storage tank and the pressure vessel to cause leakage.
