3 conditions of the stress study! Wearers of breathing apparatus are exposed to considerable physical and psychological stress when deploying fire services.! In a fire house, the physical exposure of respiratory protective equipment wearers was examined under the influence of a realistic deployment scenario and wearing the protective clothing available today. This new generation of protective clothing offers greater protection, but at the same time brings a significantly higher level of physical strain. Conditions of use: Standardized operational exercise with internal attack using a C-pipe with search for people and fire fighting. Duration of the operational exercise approx. 21 minutes Starting temperature approx. 160 C Maximum temperature 450 C BFV Oberbayern Physical stress in respiratory protection deployment 3 of 33

4 Examination criteria 50 male members of volunteer fire brigades between the ages of 18 and 32 years and valid G26 / 3, with little experience in fire operations with self-contained breathing apparatus, were subjected to a standardized exercise. The following were examined: pulse rate (n = 50) electrocardiogram (EKG departments II, V, V5, (n = 36)) during the operational exercise. Venous blood gases, blood count, electrolytes, blood clotting, body weight and body temperature before, immediately after and 60 minutes after the exercise BFV Oberbayern Physical stress in the respiratory protection deployment 4 of 33

5 results! Weight loss on average 0.53 kg, compensated with mineral water within 60 minutes of exercise.! Average resting heart rate before the exercise: 79 beats per minute! Average maximum value in the exercise: 186 beats per minute! The heart rate was above the continuous performance limit of 75% of the personal maximum heart rate throughout the exercise. (220 minus age).! 26% of the participants exceeded their personal maximum heart rate by up to eleven beats min-1 BFV Oberbayern Physical stress in the use of respiratory protection 5 out of 33

6 results! The average body temperature before the exercise was 37.3 C! Immediately after the exercise, the subjects showed an increase in temperature to an average of 38.1 C! Four test persons reached peak temperatures of up to 39.2 C 10 minutes after the end of the mission! After a regeneration time of 60 minutes, the temperature dropped to an average of 37.1 ° C.

7 results! Laboratory chemical parameters such as blood gases, blood count, electrolytes and coagulation showed reactions to the heavy physical exertion.! The blood gas analysis after the exercise showed a completely compensated acidosis (excess acid in the blood). After a break of 60 minutes, all measured values ​​were in the normal range of the initial values. BFV Oberbayern Physical stress in respiratory protection use 7 of 33

8 Conclusion: On the basis of the results available (heart rate, temperature), the stress load during the exercise using self-contained breathing apparatus for test persons is to be classified as too high.! Against the background of the high cardiovascular load, the provision of an automatic external defibrillator (AED) makes sense.! Based on the results, no risk of thrombosis or embolism can be assumed. BFV Oberbayern Physical stress in respiratory protection use 8 of 33

9 Conclusion: The use of respiratory protection leads to extreme stresses on the cardiovascular system; the effects on the blood values ​​were in the normal range and do not give cause for concern !! The cardiovascular stress of the respirator wearers is above the generally permissible values ​​and in a range that can only be achieved by trained fire brigade members. There is a health risk with untrained people.! The extreme cardiovascular load is not perceived as such subjectively by the respiratory protective equipment wearers, although objectively present!

13 Consequences of the stress study The results of the study must not only be taken note of, but must also be reflected in everyday practice and operations. Even though the risk for fire brigade members cannot be reduced to zero by following the recommendations, they do lead to a noticeable reduction in risk. The measures are divided into: Hard consequences are concrete measures to be implemented by order! Soft consequences are measures that can be achieved by raising awareness in the minds of the fire brigade members. BFV Oberbayern Physical stress in respiratory protection use 13 of 33

14 The hard consequences! The duration of use under a self-contained breathing apparatus should generally be not be longer than 20 minutes.! Wearers of respiratory protective equipment are allowed to breathe a maximum of one air cylinder (300 bar) empty without a rest break.! The practice, which has been partially used up to now, that wearers of breathing apparatus with empty equipment come out of action, change the bottles and immediately go back to the interior attack, is dangerous and must be avoided. BFV Oberbayern Physical stress in respiratory protection use 14 of 33

15 The hard consequences! If the person wearing the respirator has breathed empty of an air cylinder, he must take a break of at least 30 minutes before using it again. During this time he is not allowed to perform any physically strenuous work. He should not be physically active if possible.! The same applies if a respiratory protective device wearer who has meanwhile recovered is used for the second time. BFV Oberbayern Physical stress in respiratory protection use 15 of 33

16 The hard consequences Compensate for fluid loss! The wearer of breathing apparatus must compensate for his loss of fluids immediately after using the breathing apparatus. He lost half a liter to two liters of fluid over a period of around twenty minutes. He has to compensate for this by drinking mineral water; even if there is no feeling of thirst.! The wearer of respiratory equipment must use the recovery break to cool down and to supply sufficient amounts of fluids.! The consumption of isotonic drinks is generally not necessary. The supply of minerals must only be considered after a sweat time of over an hour. It is then recommended, for example, apple juice spritzer.

17 The hard consequences! Be HEALTHY at the time of use! Wearers of respiratory equipment may only be used with respiratory protection if they are healthy at the time of the exercise or use (see FwDV 7).! The term healthy is often interpreted very lightly; practically according to the motto: If I am not on sick leave, then I am healthy.! I am only healthy for the use of respiratory protection if I feel absolutely well. The decision about this lies with the individual respirator himself. He must learn to be honest with himself. BFV Oberbayern Physical stress in respiratory protection use 17 of 33

18 The hard consequences! Be HEALTHY at the time of use! Problems with firefighting and pregnancy in women.! Pregnancy is not a disease. In terms of insurance, the statutory maternity leave (6 weeks before the birth and 8 to 12 weeks afterwards) is equated with an inability to work due to illness, which excludes a fire brigade during this time. BFV Oberbayern Physical stress in respiratory protection use 18 of 33

19 The hard consequences! Be HEALTHY at the time of use! Problems with firefighting and pregnancy in women.! There are no generally applicable regulations and time requirements for general suitability for use and use under respiratory protection during pregnancy outside of the statutory maternity protection.! Nevertheless, a firefighter should be aware of the health risk for the unborn life and pay attention to the physical and mental stresses involved in deployment in general and in particular with respiratory protection. BFV Oberbayern Physical stress in respiratory protection use 19 of 33

20 The hard consequences! Be HEALTHY at the time of use! Problem: Fire service during pregnancy.! A pregnancy must be reported to the commandant immediately after it has been ascertained.! See also 5 obligation to notify, medical certificate of the Maternity Protection Act (MuSchG) in the notes.! From this point on, the duty of care towards the expectant mother and towards the unborn life requires that the commander release this firefighter from any duty in the danger area. This of course also includes use and exercise under respiratory protection. The same goes for a nursing mother. BFV Oberbayern Physical stress in respiratory protection use 20 of 33

21 The hard consequences! Be HEALTHY at the time of use! Problem: Fire service during pregnancy.! Employment bans for expectant mothers according to MuSchG 3 and 4! In particular, expectant mothers must not be engaged in work that regularly involves lifting, moving or transporting loads of more than 5 kg or occasional loads of more than 10 kg by hand! The BRK has been following the requirements of the MuSchG for years and releases expectant and nursing mothers from the service BFV Oberbayern Physical stress in respiratory protection use 21 of 33

22 The hard consequences Respiratory protection equipment wearers are not healthy for using respiratory protection, for example if the following signs are present:! Influence of alcohol, drugs and medication! General malaise! Cold, febrile illness! Stomach pain! Shortness of breath! Nausea / loss of appetite! Sensation of pressure in the chest! Inner unrest! Tingling in the mouth or in the arms BFV Oberbayern Physical strain when using respiratory protection 22 of 33

23 The harsh consequences of body temperature! After use and after exercises with respiratory protection, you must cool down quickly by opening or removing the protective clothing.! In winter this often causes problems because there are no suitable rooms available and the protective clothing cannot be taken off or at least opened. It is therefore necessary to ensure that there is adequate space. BFV Oberbayern Physical stress in respiratory protection use 23 of 33

24 The hard consequences of CO pollution! If CO exposure cannot be ruled out during the exercise, the participants must then be prohibited from smoking in order not to further increase possible carbon monoxide in the blood. In real use with safe CO exposure, this is all the more true. BFV Oberbayern Physical stress in respiratory protection use 24 of 33

25 The hard consequences of CO pollution For training and use, this means that any unnecessary CO pollution must be avoided. BFV Oberbayern Physical stress in respiratory protection use 25 of 33

26 The hard consequences Examples of this are :! Smoking is prohibited during and after the use of breathing apparatus and the exercise! Safely discharge exhaust gases from fire engines with an exhaust hose! Avoid any exposure to fire smoke. Anyone who is really fed up should not put on a breathing apparatus afterwards.! Use exhaust extraction devices in fire stations.! Do not stand behind starting vehicles or vehicles with the engine running, in the area of ​​the exhaust gas cloud (equipment for breathing apparatus wearers). BFV Oberbayern Physical stress in respiratory protection use 26 of 33

27 The hard consequences Walking instead of running! When deploying a fire service, every fire service member wants to complete his mission as quickly as possible. The sprint begins as soon as the order is given (often even before). It would often make sense, especially for those who wear respiratory equipment, to divide up their energy better and to achieve a balanced continuous output instead of short-term peak performance. BFV Oberbayern Physical stress in respiratory protection use 27 of 33

28 The hard consequences Rescue service care for the emergency services! Breathing apparatus wearers are always exposed to a high level of cardiovascular stress during training and in action. A sudden illness of the cardiovascular system can never be completely ruled out.! It should therefore be ensured that medical personnel with the appropriate equipment (AED) are always available at the scene. BFV Oberbayern Physical stress in respiratory protection use 28 of 33

29 The soft consequences of health consciousness.! The basis for fitness in action are the generally recognized rules of conduct for a healthy lifestyle.! The focus is on diet and body weight.! The most important starting point is undoubtedly to develop fitness through endurance training as a recreational athlete. The motto could be: The fire brigade is on the move. BFV Oberbayern Physical stress in respiratory protection use 29 of 33

30 Final Notes! Fire fighters, especially those who wear breathing apparatus, must be physically well trained and active in sports.! In connection with an optimal training and a valid G 26/3 examination, this is the guarantee for a safe and risk-free fulfillment of tasks.! It has been proven that well-trained and fit fire brigade members are much further removed from their limits than those who do not exercise and exercise continuously. BFV Oberbayern Physical stress in respiratory protection use 30 of 33

31 Final Notes! The hot training is mandatory.! The subjectively perceived exposure when using a breathing apparatus does not match the actual exposure. The physical strain is underestimated by the wearer of breathing apparatus and their own performance is overestimated. BFV Oberbayern Physical stress in respiratory protection use 31 of 33
