This incident was not unique. Fatalities from welding and hot work are often are associated with confined spaces and the areas adjacent to these confined spaces . The CSB has identified over 60 fatalities since 1990 due to explosions and fires from hot work activities on tanks, which are, of course, confined spaces.
moÂ·menÂ·ta (-tÉ) or moÂ·menÂ·tums. 1. Symbol p Physics A quantity used to measure the motion of a body, equal to the product of the body's mass and its velocity. Also called linear momentum. 2.
The law of conservation of momentum states that the total momentum of a closed system does not change. This means that when two objects collide the total momentum of the objects before the collision is the same as the total momentum of the objects after the collision.T otal momentum means the momentum of object 1 plus the momentum of object 2.his means that when two objects collide the total momentum of the objects before the collision is the same as the total momentum of the objects after the collision. T otal momentum means the momentum of object 1 plus the momentum of object 2.
