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.
By definition, Where mmmm is the mass and v\mathbf{v}v is the velocity. The standard units for momentum are kgâm/s\mathrm{kg \cdot m/s}kgâm/s, and momentum is always a vector quantity. This simple relationship means that doubling either the mass or velocity of an object will simply double the momentum.
