Water & Environment Unit Design Safety Initiative Update and Designing for Safe Maintenance
Safety Stand Down, November 2010
SLIDE 2 Aims of Presentation
WNE Design Safety Initiative: An update on progress: Guidance and information that has been generated as a result of the initiative to date. Designing for safe operation and maintenance using examples from:
- Yorkshire Water
- Anglian Water

Unit Design Safety Initiative Update
SLIDE 4
Unit Design Safety Initiative 2010
Progress to Date
Reviewing effectiveness of design hazard elimination actions;
Producing guidance on achieving best practice;
Best practice examples and RAG list posted in BPTL on PIMs;
Link to this on Unit Safety home page
Health and Safety Design Leadership workshop.
SLIDE 5
Planned Action to end of year
Project Safety Advisors (PSA) to review effectiveness of current designs in mitigating risks;
Implement suggestions from Design Leadership workshop;
WUD design processes to be reviewed to integrate safety interventions;
More best practice examples to be included in BPTL safety folder;
Review standard forms to include more prompts.

SLIDE 6
Objective Be better at identifying, managing and communicating risks
Unit Design Safety Initiative 2011
SLIDE 7
Actions
PSAs to be more involved and carry out spot checks of design decision forms;
Include all designers of all disciplines and stakeholders in design health and safety process;
Revise our design processes to include health and safety best practice;
Obtain and implement feedback from contractors/operators;
Continuous improvement of safety best practice library.

Designing for Safe Operation and Maintenance
SLIDE 9
How to achieve this?
Involve operators during the design and hazard elimination processes;
Use 3D model to undertake virtual walk through the works with operators;
Think from an operator’s perspective while designing;
Walk around with operators at end of job to identify good and bad practice and capture lessons learned in BPTL;
Incorporate lessons learnt into future designs.

SLIDE 12 Keldgate WTW Communication: Delivery Process
Design & commissioning delivery process specifically developed;
Design and commissioning review meetings undertaken with Client every two weeks;
Dedicated safety meetings integral part of delivery process:
–
2 nr. HAZOPs
–
HAZCON (construction)
–
HAZ-maintenance (lifting & access)
–
HAZCOM (commissioning)
Safety meetings undertaken using a HAZOP facilitator;
Safety meetings conducted with Client’s operational staff.

Kings Lynn H&S Review with Operations
SLIDE 20
Poly electrolyte is extremely slippery when wet so design to avoid ponding on slabs;
Kings Lynn H&S Review with Operations Some Lessons Learnt
SLIDE 21
Position valves for ease of operation
Kings Lynn H&S Review with Operations Some Lessons Learnt
SLIDE 22
WESSO valve at the top of Monsal units produces toxic gasses, so do not provide permanent access to the valves
Kings Lynn H&S Review with Operations Some Lessons Learnt
SLIDE 23
Avoid steep sloping access roofs – KL Digesters 25o slope

AutoTrack/Truck Delivery
AutoTrack models the swept paths of steered vehicles, including articulated trucks in loading areas and junctions;
Can control a second steered axle at drive time using the mouse wheel;
Any number of camera viewpoints (including drivers eye views) and switch between them during animation playback;
Display full width tyre tracks.
