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.
If the forces sum to zero, and Force is the time derivative of Momentum, then the Momentum must be constant. Constant Momentum is the Conservation of Momentum. Conservation of Momentum is a derivative of the Conservation of Energy and not an independent Law of Conservation as proposed by many including Emmy Noether. The Conservation of Momentum is the vector part of the Quaternion Conservation of Energy. The Scalar part is said to be the Conservation of Energy.
