After years of neglect, this fascinating topic has finally founds its way into the fellowship exam in the form of Question 22 from the first paper of 2016.
Microshock: small current delivered via electrodes directly into the body, bypassing the resistance of the poorly conductive skin.
Equipotential earthing
Residual current devices (RCDs)
Line isolation monitors (LIMs)
Uninterruptible power supply
Protected areas:
Equipment electical safety is classified by the permitted current leak:

Χριστοδούλου, Χριστόφορος. Recommendations and standards for building and testing an Intensive Care Unit (ICU) electrical installation. Diss. 2011. - This is a fascinating masters thesis dissertation on the standards of electrical equipment in ICU. It is not exactly a canonical source- as I expect the CICM engineers use other, locally validated guidelines -but it is an interesting read nonetheless, particularly because the author makes his recommendations on the basis of published evidence. Thus, this is the nearest thing I can find to "evidence-based ICU design".
