ELW Designer's Hazard Checklist Elimination Schedule Rev 1

1 Edge Lane West Highway and Environmental Improvement Scheme Pre-Construction Information Pack Designer's Hazard Checklist and Hazard Elimination Management Schedule General Note: During the design stages of a project, designers are required to maintain a Hazard Elimination and Management Schedule (part B of this procedure). The Schedule ' records the various significant (high risk). hazards identified by the designer(s) and, where they have been able, details of how they have been eliminated. It is recognised that not every Hazard can be designed out' and therefore the Schedule will also be used to record the residual risks of which the designer(s) are aware. The Schedule provides an audit trail of the design process and may also be used as evidence in the event that a designer is required to defend his or her actions in any HSE investigation.

2 Copies of parts A and B should be passed to all members of the project team, especially the CDM Co-ordinator. To facilitate the design process, further guidance can be found in the Industry Guidance for Designers document Part A: Designer's Hazard Checklist Project Title: Edge Lane West Job No: 1001145. Design Discipline: General Prepared By: A Fraser rd Date prepared: 23 June 2009. Notes: 1. This section of the procedure includes a list of potential hazards pertaining to a wide range of situations which may occur across Mouchel activities. Where particular categories do not ordinarily affect an individual business unit, Part A may be edited to more accurately reflect the work carried out. 2. An individual item or a whole section (by ticking the heading) can be noted as not applicable showing you have considered the Hazard area and judged it to be not applicable.

3 3. The list of potential hazards is not exhaustive, and all sections can be added to, or additional sections added, as required. Reference to the Approved Code of Practice may be helpful. 4. All items considered by the designer as having a potential high risk must be addressed on the Hazard Elimination Management Schedule '. Low risk activities can also be included if considered appropriate.
