1. Up to85% of activities did not apply PTW – no clear definition for application scope
2. No single point accountability – up to 5 permits and 77 signatures required for a single
activity, nobody checked
3. Poor PTW/JHA quality -no mechanism to guide and ensure PTW/JHA quality
4. Poor site implementation -no mechanism to ensure quality implementation
5. Inconsistent and ineffective toolbox talks –no mechanism to ensure quality toolbox talk
6. Overall compliance rate 2.25% only in 2011

WHY CHANGE
3.
IMPROVEMENT STRATEGY: SIMPLE&RELIABLE FOR STRICT COMPLIANCE
1. Aligned with project management process; organically incorporating HEMP principles
2. Single permit for any task, with max. two approval levels. One Stop Service
3. User-friendly PTW & JHA formats to ensure 100% quality PTW & JHA
4. More rational roles and responsibilities
5. Single point accountability for each step
6. New isolation approach - owner to hand over a safe work area or plant
7. Standardized daily Pre-Job Discussion on Spot
8. Daily Independent Verification of work conditions
9. Quantitative Auditing, focusing on quality

OUTCOMES
1. Initially developedin 2007, the system was then assessed by the Shell Group Risk and
Assurance Manager to be “outstanding and worthy of sharing and adoption more
broadly across Shell operations”
2. This system has helped a Shell/Sinopec JV to achieve 9 MMH w/o LTI and 3170 “Goal
Zero” Days to the date of 15th October 2014. The Sinopec Group has enforced this
system to other ventures.
3. Dozens of plants that use Shell coal gasification technology have adopted it.
4. Updated in 2012 based on the 2007 version, this new PTW system has helped PCSW
to record its best HSE performance. The PTW compliance rate has been increased
from 2.25% in 2011 to 85% in 2014. PetroChina intends to roll it out across the Group.
