3.4.3. Personal Protective Equipment (PPE)
PPE is a common method used in hazard control. Therefore, an entire chapter has been devoted
to this topic. Please refer to Chapter 5 for further guidance on this subject.
3.5. HAZARD ASSESSMENT DOCUMENTATION FORMAT
The information obtained during the Hazard Assessment should be documented in a manner that
readily identifies: the hazards associated with the task, and the controls required to safely carry
out the task. Table 3-1 provides a sample format for documenting the findings of a hazard
assessment. In the sample, the job has been broken down into the various tasks (e.g., set up
equipment, install ladder in tank) required to complete the job. Each hazard associated with a
given task has been identified, and the required control measures are specified.
