Regulation has gone too far by the duplications and irrelevancies imposed on us by the EU and, more often than not, side stepped by most EU states apart from Sweden, Denmark and Britain. In 2007/2008, more than eighty new sets of rules and regulations concerning safety and safety equipment were imposed.
Previously, the EU Noise regulations imposed impracticable, unnecessary strictures on the work place.
The Noise Regulations reduce previously acceptable noise levels (LEQ, or, ‘time weighted average’) from 85 dBA to 80 dBA. Noise is measured in ‘Bells’, and for convenient size, tenths of a Bell, or decibel. Because the human ear is ‘weighted’ in the key of A, measurement usually takes place, biased to the key of A – written: ‘dBA. It is an expression of sound intensity, or pressure and not of Energy, neither Power. The proportional relationship between Sound pressure and energy needed to develop it is Logarithmic.’
The new goal-post represents only about half the energy than before. It affects practice, not only in machine shops but makes it illegal to drive most vehicles at more than fifty MPH, whilst gainfully employed. It makes it illegal to sell motorised lawn-mowers unless they are clearly marked dangerous to the ears. Without conducting LEQ tests throughout the workplace, recording individual dosimeter readings, it is impossible to ensure what activity will remain legal and for what ear-plugs and muffs must be worn.
By 1970, Britain had the most extensive pathological evidence and practice in the field. Occupational noise effects were well known and studied. The studies gave rise to a Code of Practice, which set a time weighted average limit of 90 dBA – more than three times the energy level than now permitted. There is none or little evidence that the old, 90 dBA LEQ was inadequate and certainly not for the previous EC Diktat, of 85 dBA. The new limits, at 80 dBA, will do nothing further to protect hearing. They will complicate the workplace and expose the hazards manifest from not properly hearing workplace noise, due to ear-plugs and defenders. Anyone who tells you that noise perception is as good with and without ear-muffs on is either already deaf or thinking wishfully!
The Regulations 'made in Britain' until the new Century, made general sense, focusing attention on risk, its measurement and its mitigation. We suffer, however, from a new-age working population that has no industrial or practical skill experience or knowledge. This in itself, increases risk. Fatal Occupational accidents, pro-rata of the blue collar, exposed population, are now higher than in 1970; bearing in mind that then, there were more than 13 million blue collars and today, fewer than 2 Million!
Which is worse, is the Blame culture that has frightened 'corporates' in to being box-ticking-automatons, wholly focused on shifting the balance of responsibility on to sub-contractors.
Let's have better safety and less paper work.
We can not blame the media for negative attitudes to Health-and-safety; as the incognoscenti like to call it. The HSE can not be blamed for the current plague of grave-stone-topple-testing. It is wholly down to the pusillanimity of corporate managers who want authority without being prepared to accept responsibility and who go out of their way to avoid any in depth, practical knowledge of physical work, its associated risks and the skills required to reduce the risk!
