In recent years, due to the gradual conversion of the mine to the hanging jar method, the guns continued to decrease. In 1979, however, there was a rise in the number of smokes in the patio artillery. At the same time, casualties were often extended after the accident because of improper rescue measures. Therefore, this issue should arouse our attention. Prevention of house-to-house tobacco poisoning Harmful gases in cans are mainly carbon monoxide and nitrogen oxides. Carbon monoxide is a product of negative oxygen balance when explosives explode. It is lighter than air and poisonous to humans due to its affinity to human hemoglobin is 250-300 times larger than that of carbon dioxide, hindering the normal combination of oxygen and hemoglobin,
