A health and safety association collaborated with two research centres to examine the dissemination of knowledge of an ergonomic intervention by opinion leaders in the construction sector. The intervention was a hydraulic ladder lift that aided with loading and unloading of ladders off van roofs. Thirteen companies, with five to 900 employees, were involved. The van operators informed workmates not employed by their companies but who worked on the same site as them about the intervention. The opinion leaders informed decision makers within their companies which led to commitments to purchase similar units. They also gave presentations at prearranged health and safety meetings, where attendees indicated that they thought the intervention sounded like a good idea. In this way, knowledge of the innovation reached at least 32 more companies and potentially several thousand other employees. The study showed the potential for workplace change to be exponential.
一个健康和安全协会与两个研究中心合作，研究建筑行业意见领袖传播人体工程学干预措施的知识。该干预措施是一种液压梯升降机，用于辅助从货车顶部装卸梯子。有十三家公司，员工人数从 5 人到 900 人不等，参与了该研究。货车司机将该干预措施告知了与其公司没有雇佣关系但在同一地点工作的同事。意见领袖告知了其所在公司的决策者，从而促使他们承诺购买类似的设备。他们还在预先安排的健康和安全会议上进行了演讲，与会者表示他们认为该干预措施听起来是个好主意。通过这种方式，创新的知识至少传播到了另外 32 家公司，可能还有数千名其他员工。该研究表明，工作场所的变革具有指数级的潜力。
