  • Hi Stephen, Thanks for the feedback.
    this work was prepared for a workshop at for OH&S at NMIT. You are right it will be boring in one sitting. I conducted this in three days session. it invoved lot of practical works, filling of templates and forms. The aim of updating this consolidate work was to offer you. Where you get maximum detail at one place.
    I am once agin thankfull to you.

  73. 101. Sun Protection <ul><li>Employers should conduct a risk assessment on outdoor work scheduled for the period from September to April, when UV radiation levels peak, to assist in developing appropriate sun protection measures. Employers need to ensure protection measures are implemented. The most effective way of reducing UV exposure is to use a combination of protection methods such as : </li></ul><ul><li>Re-organising work to avoid the UV peak of the day. </li></ul><ul><li>Providing natural or artificial shade. </li></ul><ul><li>Providing appropriate protective clothing, hats and sunglasses. </li></ul><ul><li>Applying sunscreen </li></ul>
