I can’t help but think that the prevalence of utility lads on certain contracts falling out of trees (National Grid contract has a spate of incidents at one point from memory) and the subsequent early insistence of 2 line working within sectors of that industry, which sadly now appears to be being forced upon the wider industry by those with our apparent best interests at heart, stems from a few factors -
Possible unskilled workers (I think it is more likely to be complacency/rushing/trying to hit targets/cutting corners from skilled workers but that will usually register as lack of skill) not adhering to current best practice/not clipping in properly etc (maybe free-climbing and covering up the reality after the event...).
The aforementioned targets driven by price in the rush-to-the-bottom industry structure forcing unattainable productivity demands leading to corners being cut by some subbies (actual tree cutting firms/lads as opposed to the management-firm contract holders in the middle who constantly drive rates down).
Repeated ‘tickling’ of trees instead of removal/replanting, which leads to regular epicormic anchor-points and their associated issues. Trees aren’t removed as there is no incentive (for the incumbent contractor) to provide a long-term clearance as the nature of the DNO contracts is very short term, price driven and liable to change (firms win the work as cheaply as possible, appear to do as little as possible, and the unaddressed issues get passed on to the cheapest firm next time around who carry on doing as little as they can get away with etc). This unfortunately leads to the actual tree-climbing lads having to climb dodgy trees as fast as possible...
Within utilities there are often stipulations with regards ppe which can make simple tasks harder, and can subsequently lead to increased task-loading issues for climbers (re-sheathing a climbing saw between cuts, wearing cut-proof gloves whilst using a silky etc). I don’t personally believe these HSEQ statistic-driven ‘solutions’ always benefit overall site safety (from both a practical view and importantly also from an alienation-of-the-workforce, those-desk-pushers-don’t-know-what-they-are-talking-about-so-we-might-as-well-ignore-them angle).
These issues are unlikely to be addressed as accountants hold the purse strings at the end of the day - it is much easier for those in charge to say ‘You need more anchor points’ and then (unfortunately rightly from a legal point of view) be able to point the blame at the individual climber who doesn’t adhere to this as being at fault when corners are cut and accidents happen.
I’m not sure what the answer is - one is obviously less likely to fall to the ground if tied in with double/triple/quadruple the number of ropes and anchor points but the limited statistics available don’t give the full picture.
The HSE are essentially God in this scenario (certainly from a legal point of view) - I guess it will basically become an on-site paperwork exercise risk assessing two ropes out where their use makes the job more hazardous than it needs to be.
