Recent research indicates that lifts in the UK are now insufficiently spacious due to the rising rates of obesity, posing potential safety risks.
Experts have highlighted concerns about the possibility of individuals becoming trapped in lifts, especially emphasizing the challenges faced by obese individuals when lifts become overcrowded. Studies have revealed that elevator capacity indicators, specifying the maximum number of passengers, have not been revised in the past 50 years despite the significant increase in average body weight among Britons. University College London (UCL) conducted an examination of lift weight guidelines across Europe, uncovering that these guidelines have not been adjusted to accommodate the higher average weight of citizens since the early 2000s.
The results, presented at the European Congress on Obesity in Istanbul, demonstrate that historical standards were based on an average weight of approximately 12 stone (75kg), reflecting the average weight of a British man in the mid-1970s. However, the current average weight of a British man is 86kg, and for a woman, it is 73kg.
Nick Finer, a clinical professor of medicine at UCL and the author of the study, expressed concerns, stating, “The failure of lift manufacturers to adjust to the increasing levels of obesity and body size results in overestimations of lift capacities, potentially leading to longer journey times and compromised safety.
“Anyone who has visited a hospital in England or the UK is familiar with the lengthy waits experienced when traveling up multiple floors. While some lifts have mechanisms to prevent operation if weight limits are exceeded, not all lifts are equipped with such features.
“I have already been approached by individuals recounting incidents where people have been trapped in lifts due to weight limits being surpassed, even when there were fewer occupants than the stipulated maximum capacity.”
Manufacturers of lifts are mandated to display the maximum weight allowance and the maximum number of passengers a lift can hold. Industry standards dictate the passenger capacity by dividing the lift’s maximum load by the average weight of a passenger.
The research scrutinized lift safety in the UK, as well as in France, Germany, Italy, Spain, Austria, and Finland. It revealed that weight capacity limits had increased in alignment with the average body weight between 1972 and 2002, rising from around 62kg to 75kg per person. However, companies have continued to use the same limits for decades despite the escalating obesity crisis.
Prof Finer mentioned that American scientists had suggested raising the standard to 80kg in the 2020s, but this proposal was not widely adopted. He elaborated, “Manufacturers seemed to have shifted towards calculating the floor space occupied by an individual, assuming a person’s shape to be oval rather than circular.
“They have overlooked the fact that as obesity rates rise, so does the space occupied by individuals.
“In a standard-size lift with three or four passengers, the entry of an obese individual can draw unwelcome attention. Similarly, if an obese person is already inside the lift and additional passengers attempt to board, it can lead to uncomfortable situations.”
