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.
Momentum is a scalar quantity dependent on mass and velocity. P (momentum) = mass x velocity. Since an object that is not moving has zero velocity, p = mass x zero, and thus p â¦ = 0 for all stationary objects. 1 person found this useful.
