Today, in the fire investigation field, there is a greater emphasis on fire science and engineering than ever before. In addition, several ancillary fire effects, fire patterns, and post-fire analysis issues were successfully examined. %%EOF 0 140 0 obj <>stream During the past 20 years, a significant shift has occurred. h�bbd```b``��A$c�< endstream endobj 114 0 obj <>>>/Filter/Standard/Length 128/O(�L,���k}�����\rir�D�n,DU4��n���)/P -3392/R 4/StmF/StdCF/StrF/StdCF/U(牋�$l��p��&X� )/V 4>> endobj 115 0 obj <> endobj 116 0 obj <> endobj 117 0 obj <>stream endstream endobj 81 0 obj <> endobj 82 0 obj <> endobj 83 0 obj <>stream �K�����e�[��y�͸�\� )��R�±d`�9�� 2c������M+^�.bkh�����c��I=A��z����[ ���m��d$�$'��wթ�]G/����)�E�#�-1t���G�wT��k�5c�;M2wc��>�Q4ť >^4Z�za�#����ufÃ��mԯndh���`��ށ%�@k The research burns have enhanced the knowledge base of the fire investigation community. � bA�H$?�6� :�+������ e�x|ӫ�8+W�ڒ0�������[ܓ��^gEX���%:����rUX�d���$I � f&��dμ�ӄUC�k��|�Q���8��9���؄��Z��(` R�J h�b```f``�g`a``�� Ā B@1V ����Ġ�u�����_�&�I\P� e����P��QQR�("rl�Cl�Ќ�6JM "X�y�Wr���f��0���� �&����� h��V�n1��ylTQ��]�B�R��B�J�� �d�e��R���,�B��}�VƗ���gHS��(6-�g�l��� e����U��48����+8� The examination of the burn patterns following a fire is not a forensic examination and “burn pattern analysis” is not a forensic discipline.
