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.
Angular momentum is a vector quantity (more precisely, a pseudovector) that represents the product of a body's rotational inertia and rotational velocity about a particular axis.elocity of the particle m with respect to the origin O can be resolved into components parallel to (v //) and perpendicular to (v â¥) the radius vector r. The angular momentum of m is proportional to the perpendicular component v â¥ of the velocity, or equivalently, to the perpendicular distance r â¥ from the origin.
