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 the product of the mass and velocity of an object. In other words, the momentum of an object depends on either the objectâs mass or velocity. If a bicycle and car are moving with the same velocity, the car has more momentum because of its larger mass making it harder to stop.
