조선업 및 화학공장 등 산업현장의 화재사고 중 용접$\cdot$용단작업시 불티에 의해 주위의 가연성물질을 착화시켜 화재, 폭발 사고를 일으키는 원인이 되고 있다. 이들 불꽃은 수평방향 및 틈새, 배관구멍 또는 마루나 댁의 작은 개구부 등을 통하여 비산되고 상당시간 훈소화재 형태를 유지하다 발화되어 화재의 원인이 되고 있다. 특히, 용단작업시 비산되는 불티는 $1,600^{\circ}C$ 이상의 고온체로서 산소 압력에 따라 다르나 약 11 m(산소압력, 7 kg/$cm^2$)까지 비산되어 이 반경내에 있는 가연물에 착화될 수 있으므로 이에 대한 예방대책이 필요한 작업공정이다.

Recently, fire and explosion accidents caused by sparks scattered during welding and melting work in the work place where flammables are present. The causes of such fire accidents are mostly non-compliance with basic safety rules such as the removal of hazardous goods and the prevention of sparks scattering. It is strongly recommended to revise Industrial Safety and Health Act. This study analyzes the fire and explosion accidents in the work of firearms, such as welding and melting work, and analyzes the causes from a system perspective, and proposes an improvement plan for the system such as expanding the number of fire monitors, pre-approval of fire risk work, and intensifying fire prevention safety education.

This study was undertaken to evaluate the performance of flame retardant for fire precaution from sparks at welding-cutting process in industry sites such as shipbuilding yard and chemical factory. As the results of the performance experiment, six kinds of welding blanket in samples that are used commercially had enough in the performance of flame retardant. Nevertheless, the performance to fire precaution un welding blanket shows that the coaling product of two kinds with fiber glass is not sufficient. The lower oxygen index to welding blanket is considered that it is more than 30 in domestic standard. We suggested that the performance improvement of flame retardant for welding blanket need continuously, and the guideline of the flame retardant to welding blanket should be considered and established.
