What is a character arc? A character arc is the measure of how a character changes over time. These arcs are linear — so as to say they always have a beginning and end. But they don’t have to coincide with story arcs. For example: a story arc may start at its linear end, but...
Given the nature of the injuries that can be sustained in an Arc Flash, the general lack of awareness of Arc Flash risks is still disappointingly low. Our Arc Flash Survey in 2017 revealed a staggering 78% of respondents were still unaware of what the Health & Safety Executive’s (HSE) ...
