Good if your doing repetitive work and operations tasks like maintenance cleaning shutdown etc..
But breakdown work involving production loss where skilled tradesman know plant should be competent to asses ever changing risks on jobs .Tasked are undefined Levels of Isolation and energy dissipation are usually identified with exposure and experience lifting rigging scaffing and basic trade skills should not be underestimated A risk assessment simply doesn't work.
A lot of this comes thru companies using labour hire contractors who aren't aware of the plant they are working isolation is an issue hazards become an issue on the jsh becomes and advantage to workers .
If your trained competent and are specialized personal in your industry specific there is no need. The personal should be competent in there job and that includes common sense and the ability to asses risks.
They key with breakdowns when shutting down plant is communication with operations managers and supervisors. Using correct isolation procedures (which have come thru risk assessments ) confirmation of the testing of isolation and the tagging out policy which include personal danger tags.
If you are doing repetitive work there should be a procedure for it and if it's any good it'll cover you for most situations, if you are using a JSA for repetitive work I'll bet money it's no good and/or not being followed.
While I'd very much like to subscribe to the theory that trademen/specialists can be relied upon to apply good judgement unfortunately the evidence to the contrary is pretty damning, similarly the old "common sense" that isn't so common. From my experience what I see is that level of education has little to do with either common sense or practical application of it, I've seen engineers (supposedly some of the worst) with great common sense and an ability to apply it (call it situational awareness) and I've seen tradies that have none, I've also seen people who did not complete high school (or anything after it) that are better than all of them.
Here's some of what I've seen (again first hand) with the consequences excluded (where I can, some of which I'm aware have been done by others with far more serious consequences that what I saw), these cover the entire spectum of education, experience and competency: 2.2kg Cast primer (with detonator in place) bashed against a rock to get it to "fit" inside a piece of poly pipe, chemical line openned upstream of the isolation point (while not wearing PPE), face charged while still being bored, working with explosive while smoking, load lifted with uninspected and out of date sling (dropped), welding while raining and/or under leaking water, 9" cutting disc used on 7" grinder without guard (similarly with 4/5" grinders), worked on wrong piece of equipment (unisolated and even though it was labelled) I could go on and on and on.
Over my 20 years what I've seen is a progressive lowering of skills, experience, critical thinking and to some degree standards and what has been lost mostly is an understanding of
WHY we do some of the things we do, mostly this is not because the HSE guy says we have to but because somewhere along the line someone has done something (sometimes dumb and sometimes not) and got themselves seriously injured or killed the result being that as an industry we tried to learn so it doesn't happen again (again I have plenty of examples).
I guess my point is that it's individual but what is required (by law) is consistency and there is only one way to achieve that (sadly). I do know tradesmen who I would trust to do the right thing without the paperwork as I do professionals and equipment operators, the irony is the guys (girls) I know who I'd trust to do this also happily do the paperwork and do it properly. In my experience being safe is an attitude and yes it does not require paperwork to have it and nor is the paperwork going to protect you if you don't. My experience is people who "know better" generally are not those with the attitude required, they stopped learning (and/or applying their skills of observation) long ago and as a result when situations change are also likely to still "know better" with sadly predictable results.
