Hi ya, and welcome. The ones I have used in the construction sector are; 1. Permit to dig (or excavate) 2. Permit to penetrate the ground (using pegs or road pins) 3. Ladder permit (short duration pole or step ladders) 4. Hot works permit (like you said) 5. Confine spaces (like you said) 6. Permit to enter (more to do with finished rooms and controlling the works in that area, and limiting th enumber of persons) 7. Permit to load (for falsework/ formwork) You can have a permit for just about anything though, depending on the works, and if after risk assessments there may still be an element of a hazard that needs further controlling.

We use the PTW mainly as a way of controlling contractors, who can turn up and wander off into hazardous areas with only limited supervision. They are unfamiliar with our systems and our staff might be unaware that they are on site. The PTW makes sure that they are aware of what they are permitted to do and our people know that they are about and working on site.

In an everyday sense, 'permit to access' is a common application. Plant rooms, switch rooms, lift motor housings, window cleaning cradles, roof spaces and the roof itself. Complexity is determined by both the nature of the resident hazard(s) and the nature of the work itself. Not forgetting that in many instances the 'normal' alarm sounders sometimes can't be heard. The Fire Service don't take kindly if they see the general population out assembled in the Car Park on their arrival, whilst contractor's personnel are still scampering about up on the roof, totally oblivious to the emergency.

Thanks for all your advice and comments guys.
