25. First Aid to the Burned. 



If the clothing is on fire the flames may be slapped 

 out, unless a large amount of the clothing is burning. Tn 

 this case the person should roll, or be rolled, upon the 

 floor. This crushes out the flames. Where possible the 

 person should be wrapped in any heavy material, such as 

 a mat or a rug, or even a coat. The wrapping should be 

 very tight. The person should not be allowed to stand, 

 as the flames will rush upward, setting more of the cloth- 

 ing on fire, and perhaps causing the person to breathe 

 the flame, which is very dangerous. Under no circum- 

 stance should the person be allowed to run about. If 

 persons would act quickly, harmful and even many a 

 dangerous burning accident could be avoided. Be quick !
