المثبط الأكثر استخداماً في العالم.. الكشف عن المادة وردية اللون التي تستخدم في إخماد حرائق لوس أنجلوس
6 شهر 17 14006



صحيفة المرصد - وكالات: كشفت وكالة "أسوشيتد برس" معلومات حول المادة وردية اللون التي غطت أسطح المنازل، السيارات، والشوارع في لوس أنجلوس الأمريكية خلال الأيام الماضية في محاولة لإخماد الحرائق ومنع انتشارها.


وأوضحت أن المادة تعرف باسم "فوس-تشيك"، وهي مادة مثبطة للنيران تستخدم على نطاق واسع في الولايات المتحدة منذ ستينيات القرن الماضي، وتعد "فوس-تشيك" المثبط الأكثر استخداما في العالم.


وأضاف متحدث باسم شركة "بيريميتر سوليوشنز"، المصنعة للمادة، أن اللون الوردي الزاهي يضاف كمؤشر مرئي لمساعدة الطيارين ورجال الإطفاء في تحديد المناطق التي تم رشها بالفعل.


وبدلا من إطفاء النيران مباشرة، يتم رش "فوس-تشيك" مسبقا لتغطي النباتات والأسطح القابلة للاشتعال.


ووفقا لتقرير في صحيفة "نيويورك تايمز" الأميركية، فإن المادة تمنع الأكسجين من تغذية النيران، مما يخلق حاجزاً يبطئ انتشارها، وتتكون المادة أساسا من أملاح مثل "أمونيا بولي فوسفات"، وتتميز بقدرتها على التحمل لفترات أطول من الماء، حيث لا تتبخر بسرعة.


وذكرت صحيفة "نيويورك تايمز" أن الأبحاث الناشئة تشير إلى أن المواد الكيميائية الموجودة في المثبطات قد تكون سامة، بما في ذلك المعادن الثقيلة، مما يؤثر على الحياة البرية، الممرات المائية، وحتى صحة البشر.
