Do the contractor need to us hard hat during their fixing of lights in the ceiling? The contractor is just using the A-frame ladder with 5 mtrs height inside the office? I feel its no need..any opinion is really appreciated.

Hmm..Interesting question. First, as the previous poster has mentioned, a risk assessment should be conducted to assess the potential risks and controls. As a rule I think it is not necessary to wear a hard hat when working on a ceiling, indeed they can often be more of a hindrance unless they are the peakless type used by scaffolders. A 5 metre step ladder seems very high, would a mobile tower not be more suitable for the task?

Forgetting the site rules for a minute, whilst working on a ceiling there may be no risk of anything falling, however there is still the risk of someone falling from 5m and hitting their head. Therefore a hard hat without a chin strap would be of no use whatsoever, unless they were clipped on to the rung with a karibiner via a harness/ lanyard and the step ladder properly secured. So, plenty of things to consider before making a decision.

Thank you very much to all for your valuable feedback! I am clear now what to implement! With regard to the use of A-Frame Ladder, what are the practical measures while using this Ladder ( contractor standing on it to max 3 mtr heights)? The situation was, there was no strong support to hook the fall arrest while using the ladder and I have given already training to the users.
