Hi LD, the snake oil salespeople have been out there for decades!
The difference is that they have evolved to pretend that technology can do everything for you, and make whatever aspect of compliance easier, often these days by getting AI to produce generic documents, training programmes etc etc.
As AK says, all very good in terms of document control management, but whether what is offered is suitable for YOUR staff, students, supply chain and third party stakeholders is another matter entirely.
So, you buy an off the shelf manual handling training package that tells you how to safely lift a cuboid box that weighs say 20kg. Very good if that is what the workforce are handling in a warehouse, UNLESS they have to go up in a platform (typically an "order picker") to retrieve some package from the back of racking.
However, perhaps not what is suitable when a pupil is injured and you might have to handle an "object" that weighs far more than 20kg, isn't cuboid, and which keeps trying to move!
...and the standard training packages generally tend to assume that the person doing the task is generally trying to follow the rules.
You are in a secondary school and sometimes the students will play up, unless your school is unique - or totalitarian in its approach!
I think what you need is a wish list of what you want in terms of:
(a) processes for the broad principles of managing H&S - risk assessment, active monitoring (inspections, examinations and audits), reactive monitoring (incident and near miss recording) and things out of routine such as maintenance and contractor activities ete.
(b) training needs
In each case considering how much of each can be wholly or partly automated and how much needs to be bespoke to YOUR organisation.
....and much of this could probably be put together by one of the school's IT technicians IFF you tell them what you want to achieve.
Getting checks done on fire extinguishers doesn't need some all singing and dancing hi-tech software solution but could be done with a simple spreadsheet.
This asset needs to be maintained at such and such intervals or when A happens. It needs to be examined at a different interval or not at all.....and so on.
....and it is very unlikely that the off the shelf COSHH package is going to cope when the students are going to mix chemicals X, Y and Z in the chemi lab to demonstrate a highly exothermic reaction - for the simple reason that the supplier who gives you a Safety Data Sheet for X may not know that you are going to mix it with Y and Z nor in what quantities.
