[tips] how to do good personal protection at low temperature?

To protect the damage caused by low-temperature operations, the following points should be made:

1, relevant industries and enterprises, should pay attention to the unit's safe production, labor maintenance rules and regulations, there should be related to antifreeze warmth, so that there are rules to follow.

2, should strengthen the inspection and maintenance of refrigeration equipment, prohibit "run, run, drip, leak." If it is found that ammonia leakage should be promptly adopted methods to repair, to prevent leakage of events to expand. To ensure the ventilation of the refrigeration plant is good, if a lot of leakage of ammonia should be discharged outside the house in time to prevent the occurrence of poisoning. It is necessary to install suitable gas masks or oxygen respirator in the refrigeration workshop. With regard to the use of the Freon-12 freezer, it is necessary to equip the necessary inspection equipment such as halogen lamps. When ozone deodorization and deodorization are selected, the ozone concentration in the reservoir should be detected at all times. The hygienic standard for ozone safety concentration is 1.5×10-5.

3, low-temperature operation, cold water operations should be as far as possible automated, mechanized, to prevent or reduce personnel cold operation and cold water operations; to control the operation of low temperature, cold water; in cold winter operations, there must be cold-proof heating equipment, open-air operations to be set Windproof sheds and heating sheds should be made of materials with low thermal conductivity, low hygroscopicity, and good air permeability. When operating, it is necessary for workers to wear warm clothes, shoes, caps, gloves, and other warming products; cold clothing should be prevented. Wet, the limbs can not be tied too tightly, so as not to affect part of the blood circulation; close to the cold storage room to set up a locker room, to ensure that the workers have satisfied the number of rest and rest time, the best conditions for the workers after the job to wash hot Water bath.

4. Regularly check the workers' physical status and do well in health monitoring. Any person who is over 50 years of age and suffers from diseases such as high blood pressure, heart disease, and gastrointestinal dysfunction should be promptly removed from the low-temperature, refrigerated operation.

5. Pay attention to the special maintenance of female workers. It is forbidden to arrange female employees in “four phases” to engage in refrigeration operations.
