| Post subject: | Hazard risk Evaluation - 70e Annex F |
I have a few questions about the Hazard / Risk Evaluation Procedure on page 77 and 79 of the 2009 edition - 70e. 1 - What does the probability factor mean ? Probability of an individual doing the task ? Probability of making a mistake ? Probability of things going wrong ? 2 - What does the CI in the Class column mean ? 3 - Is the Severity number 1-4 based on a flash analysis or shock hazard , or both ? I was asked to explain this and was at a loss for these items. Any help will prevent this from happening again Thanks Jim jpbtrainingassociates.com |
