working at confined space is one of the most dangerous of all workplace hazards especially  when it accompanies with anoth dangerous work like welding. Electrical shock, oxygen deficiency,under pressure cylinders, explosion and fire are most potential dangers of welding job at confined space. Gas testing at confined space before starting job and also using suitable personal protective equipment and welding safety requirement can help reduce dangers of welding at confined space

 INTRODUCTION

Working at confined space is potentially one of the most dangerous of all workplace hazards. It’s been calculated that working in a confined space is 150 times more dangerous than doing the same job outside. Over the years, many workers, in a range of occupations, have lost their lives or suffered serious harm while working in tanks, vats, sumps, sewers, pits, traps and other types of confined space. To effectively control the risks associated with working in a confined space, a confined Space hazard assessment and control program shall be implemented for your workplace. Before putting together this program, make sure to review the specific regulations that apply to your workplace. All jurisdictions within Canada have
regulations dealing with confined space entry. The regulations can vary slightly from jurisdiction to jurisdiction [1]. Also, there are many different types of potential hazards in welding jobs. Everyone involved shall be aware of what these hazards are

Welding and cutting processes are safe, and the risks fromthe hazards can be reduced, if they are carried out correctly and with care. In this paper the concept of confined space and its hazards will be discussed at first. Next, the hazards of welding job in confined spaces and safety requirements to decrease these hazards will be expressed
