Shoring is the practice of using supports to prevent cave-ins or collapses in excavation sites, while shielding involves using physical barriers to protect workers from falling debris or collapsing materials. Shoring provides structural support to the excavation walls, while shielding creates a safe zone by blocking potential hazards.
A static-shielding bag is designed to protect electronic components from static electricity by dissipating charge buildup, while a static-resistant bag is meant to reduce the generation of static electricity but does not provide full protection like a static-shielding bag. Static-shielding bags are commonly used to transport and store sensitive electronic devices, while static-resistant bags are used for general electronics packaging.
The main difference between Flux-Cored Arc Welding (FCAW) and Gas Metal Arc Welding (GMAW) is the type of consumable electrode used. FCAW uses a tubular electrode filled with flux to protect the weld pool, while GMAW uses a solid wire electrode with an external shielding gas. FCAW is often preferred for outdoor welding due to its self-shielding capabilities, while GMAW generally produces cleaner welds.
It is called shielding or screening effect. Inner electrons shield the valence electrons from the positive charge of the nucleus, reducing the attractive force between them.
The shielding effect is more noticeable on metals because they have more loosely held electrons in their outer shells that can effectively shield the inner electrons from the nuclear charge. In contrast, non-metals tend to have stronger attractions between their electrons and nucleus, making the shielding effect less pronounced.
Materials with high atomic number, such as lead or concrete, are effective at shielding against gamma rays. The thickness of the shielding required will depend on the energy and intensity of the gamma rays. Multiple layers of shielding may be necessary to provide adequate protection.

When referring to concrete work (using a structural suspeneded slab as an example) Shoring - support structure for formwork before concrete is poured and while it is curing. The formwork is the plywood and the shoring is the posts. Reshoirng - support structure for the cured or partially cured concrete - installed after the formwork and shoring have been removed. Usually used as additional support for the partial cured concrete (which has reduced strength) to allow construction work to continue on the slab until it has fully cured.

Shoring of a trench or excavation can cause a caught-between hazard.

A website with a good explanation of "off-shoring" is the Chel Ramsey Productions website. It is explained there that "off-shoring" is another term for "outsourcing". It also explains how the process works.

Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
Typically, at 3 feet, the excavation should be inspected by a competent person to see if hazards exist. At 5 feet, CAL OSH requires a permit if workers will enter the excavation. This will require that excavations 5 feet or more be protected from collapse. This may be done by sloping, shoring, or shielding- or by a system designed by a Registered Professional Engineer (PE). Excavations greater than 20 ft in depth will be protected by a system designed by a PE.

The main purpose of shoring is to prevent the deflection of beams,girders,and slab;to support the structure;and for safety purposes. By: Engr.Ray, Structural Inspector
