| Background:Individual protection is an important measure to prevent harm, to protect the health and safety. Corresponding responsibilities and tasks are regulated to emergency rescue in special health terms to ascertain that rescue staff clearly understand the performance and limitations of various protective equipment and are capable to apply suitable equipments. Recently, on many occasions cases of poisoning by rescue workers in the implementation of chemical accident rescue process are reported home and abroad. Personal protective is important to both personnel safety and overall performance of the rescue. Individual protective equipment on the physiological and health effects and the use of safety, acceptability and wear comfort are the embodiment of its quality characteristics.Objective:Personal protective equipment is very prominent in field operations, as well as during evaluation process. This study is designed based on field work of poisoning control, through laboratory and field simulations, to explore the impact of the typical individual protective equipment on human physiology and field operating to direct personal protective equipment application, and provide the basis for the development of China’s guideline for individual protective reserves in health emergency response to enhance the emergency emergency competence.Methods:According to GJB3664-1999, breathing, body temperature, heart rate and other physiological indicators of subjects are tested in the laboratory by wearing imported and domestic types of individual protective equipments, under set environment.According to GB/T23465-2009, Delphi method is carried out to rate the2types of individual protective equipments, combined with the results from the subjects.Results:The body heat storage of A-level imported protective equipments is (133.40±21.53W) lower than that of domestic equipments (137.79±25.82W) with no significant difference (t0.05(5)=2.571) under high temperature and humidity.2. The oxygen uptake of A protective equipment is17.2ml/(min·kg), compared to13.7ml/(min±kg) of C protective equipment under high temperature and higy humidity.(3) According to experts score, the first3important factors of safety for level A protective equipment are breathing, alarms and vision, while for level C protective equipment, the indicators are stability, breathing and vision. In addition, easy to use is the most important factor for protective clothing in terms of operation.(4) The maximum mean heart rate is tested by wearing both import and domestic Class A and C protective equipments, which is158times/min,157times/min,143times/min and145times/min, respectively.(5) Domestic A-level protective equipment is scored74.93±10.88while imported Class A equipment is scored79.78±5.81without statistically significant (P=0.063). It shows that some functions, such as freedom of head movement, bow rotation freedom and lower extremities are higher scored in imported equipment than that in with statistically significance (P=0.034, P=0.011, P=0.030). Non-security related indices of mport Class A individual protective equipment are higher ranked than those in the domestic equipment with statistical significance (P=0.048).(6) The overall score of C protective equipment domestic and imported are (80.65±9.38) and (86.40±9.92) with statistic significance (P=0.00099). Stability ranks the highest in security-related index, while conditioning the lowest. Both security and non-security indices of imported equipment are higher than that of domestic equipment with statistic significance (P=0.005, P=0.048).Conclusion:(1) A-level protective equipment is applied at risk when it is alarm under high temperature and humidity due to the threshold of heat stress, which should be less than30min.(2) C-class protective equipment should be performed at room temperature within60min, while under high temperature and humidity, it should be less than40min.(4) The cooling vest does not contribute to the decrease of body heat, which is not applicable to apply A protective equipment under high temperature and humidity.(5) The safety of protective equipment should be most important in emergency rescue. The performance of A-level protection equipments meet the basic needs of health emergency response.(6) Increase telecommunication and effectiveness to adapt to the field needs. Improve individual protection equipments to enhance the comfortability. Strengthen training on personal protection in emergency rescue and improve the usefulness of protective equipment. Intensify study on the health monitoring of the emergency rescure...
