One ever-popular health and safety issue on social media concerns the dangerous practices that people continue to engage in when working at height.
Incredulous bystanders, armed with their mobile phones, are able to photograph the latest misuse of ladders or steps as workers foolishly attempt to defy the laws of gravity.
Inadequately prepared, these 'cowboy builders' often improvise means of reaching areas well outside their reach. They have supreme confidence in their abilities, which - they seem to believe - include everything from the balance and the dexterity of a trained gymnast to the strength of a strongman and the analytical capabilties of a mathematician. The ladder structures often balance precariously, sometimes aided by assistants who have to support the structure with brute strength while the ladder user is fully extended from the topmost rung.
However, health and safety statistics reveal that falls from height continue to be the most common type of fatal accident, accounting for 29% of all UK workplace deaths in 2014-15. Also, it is a major contributor to loss of working days due to recovery from injuries sustained through falling. Regrettably, these figures remain stubbornly high, showing no indication of decreasing.
So, as the bystanders capture the action, they have every reason to fear the worst, as things are likely to have a sad ending - if not today, then in the future, as luck and extremely good fortune cannot go on forever.
