The confined space exists potential hazards.They are :
Oxygen deficiency due to rust formation ,chemical reaction,combustion or absorption.Any reduction in oxygen in the atmosphere below 19.5 % can impair performance by causing fatigue and loss of reasoning ability.
Oxygen enrichment through accidental ventilation with oxygen or leaks in Oxy Acetylene equipment will increase flammability of materials.Oxygen level in the confined space should not be more than 23.5% .
Fire & explosion may be occur .Toxic substances present.
Falling of objects as a result of materiel or equipment brought into a limited volume of space that requires more than one working level.
Mechanical equipment that forms of these normal process will be isolated so that it does not energize automatically or accidentally.
Electrical shock could result from preferment installations or from defective temporary equipment,tools cords & lighting's.
