When it comes to designing or evaluating a product or process, the safety factor is an essential aspect to consider. It refers to the extra margin of safety that is built into a design or process to ensure it can withstand unforeseen or unexpected situations. There are several synonyms for safety factors, including safety margin, safety reserve, safety net, safety cushion, and fail-safe margin. These terms indicate the extra capacity and protective measures put in place to avoid failure or damage in the event of any uncertain occurrences. By incorporating adequate safety factors, engineers and designers can create robust and reliable products that can perform well in even the most challenging circumstances.
