TLDR
Studies of the effects of fatal electric shock have recently challenged certain almost traditional beliefs and it is important that electrical engineeres should be aware of this new knowledge, and how it has led to a revision of the methods of giving first-aid treatment to accident victims.Abstract:

A Complete Electrical Shock Hazard Classification System and Its Application
TL;DR: In this article, a comprehensive electrical hazard classification system based on various research conducted over the past 100 years on analysis of such systems in R&D and on decades of experience has been developed, including work controls for these hazards, better selection of PPE for dc work, improved training, and a new electrical severity ranking tool that is used to rank electrical accidents and incidents with various forms of electrical energy.

Electrical shock hazards and safety standards
TL;DR: A general overview of the potential sources of electric shock in laboratory environments is presented in this paper, where the authors discuss the basics of grounding, protection equipment and devices, codes and standards, the effects of electricity on the human body, electrical parameters for 60 Hz shocks, highvoltage safety principles, and typical laboratory accidents.

An Investigation of Low-Impedance Low-Voltage Shocks
TL;DR: In this paper, the authors reviewed low voltages (0 to 240 volts) shock hazards and biological fibrillation thresholds from the standpoint of improving the existing data base and the principal uncertainties with existing data are the impedances of the human body under low-voltage low-impedance source shock conditions, and the relationships between lethal thresholds observed in animal tests and the scaling of this observed data to humans.

Probability Surface Distributions for Application in Grounding Safety Assessment
TL;DR: In this article, the authors developed a probabilistic approach based on a statistical analysis of the IEC published curves of ventricular fibrillation, which can be extended to take into account other statistical parameters and may lead to a more objective measure for making investment decisions in hazard mitigation.

Electric Shock Hazards Beyond 50/60 HZ and DC
TL;DR: In this paper , the effects of shock from alternating current (ac) power frequencies (50 and 60 Hz) and from direct current (dc) have been studied for a century and thresholds for safety are now clearly defined in worker safety standards (i.e., NFPA 70E).
