cement - What could have caused an electrical shock from a ...
Cement is not a good conductor so a live electrical charge from the cement is a near impossibility. But that doesn't rule out a static charge. If the humidity was right and enough friction from the wood to break some electrons free just might generate a static charge. But I have never heard of cement getting a static charge before but then ...

2.1 Mechanisms during grinding in the cement mill The mechanisms in charge when improving the grindability of a clinker must be explained from a physico-chemical point of view. In general, the surfaces of the clinker particles are not in thermodynamic equilibrium due to the incomplete surface bonds, which lead to a free surface charge.

Best Safety Practices for Forklift Battery Charging
During the charging process, batteries emit hydrogen gas that can cause flames or explosions if it is allowed to build to excessive levels. Exposure to Electricity: Active battery cells hold an electrical charge which can short circuit if a worker touches them. This can cause serious electrical burns, and arcing increases the risk of explosion ...
