一、前言

伴隨石化工業和高分子產業興起，使用含有自然發火物質機會相對增加。根據國內外消防統計，
不論研究單位、工廠、商店乃至一般家庭，這些物質的儲存、使用及處理過程均有起火可能。

臺北市政府消防局近半年來已接獲多起自然發火相關案例，多發生在 SPA 館或乾洗店，因毛巾、
衣物沾有按摩油類，烘乾後在無其他火源情況下，因氧化熱而自然發火。
本篇針對氧化熱自然發火原理、條件、種類及運用熱裂解氣相層析質譜儀進行實驗分析，以確認

發火物質有效研判起火原因。

With the development of the petrochemical and polymer industries, the chance of using spontaneously
combustible material is increasing. Fire protection statistics from Taiwan and overseas shows there is risk
of fire is the storage, use and disposal of these materials whether by research institutions, factories, shops or
households.
Taipei City Fire Department has received a number of reports of spontaneous combustion in the last since
month mostly in spas or dry-cleaning shops; towels and clothes are stained by massage oil and after they are
dried in a spin dryer natural combustion occurs due to oxidization, without any contact with a fire source.
This article discusses the principle, conditions and types of oxidization spontaneous combustion and the use
of Pyrolysis gas chromatography mass spectrometry (Py-GCMS) to carry out experimentation and analysis,
to allow the combusted material to be identified and the fire cause to be accurately judged.
