Ballast Dust: Is This A Risk? Caroline Meek Head of HSEA National Delivery Service Network Rail
Ballast Process: Quarry Ballast is produced from granite quarries Blasted Crushed Sieved Washed Loaded into box wagons Process Improvements Dust reduction
Ballast Process: LDC’s Off loaded Stored in stock piles Reloaded into wagons
Ballast Process: Worksites Ballast is offloaded 30-40% over ordering
Ballast Delivery Mechanisms
Operational Safety Risk Lack of visibility
Occupational Health Risk Total inhalable Respirable Silica Eyes, Nose, Mouth & Skin
Occupational Health Risk Silicosis Symptoms Chest tightness A cough, with or without sputum Shortness of breath Premature death There is no current cure for Silicosis
Ballast Dust Working Group Members
Exposure Monitoring A number of occupational health data sets have been analysed Data range is from 2007 to 2011 RAG Status applied to results
Total Inhalable Dust WEL10mg/m3: No exposures over the WEL A very small number of individuals had up to 5mg/m3 WEL exposure Remaining exposure levels were approximately 1mg/m3 or less
Respirable Dust WEL 4mg/m3 Activity: Ballast Drop from Falcon Wagons using RRV’s COSHH intervention required: Technician Site Supervisor Crane Controllers RRV Driver (as cab window was open) Engineering Supervisor
Respirable Silica Dust WEL 0.1mg/m3 Amber Activity: Ballast Cleaner and Falcon Wagon COSHH intervention required: Ground staff within 10m of activity Red Activity: Falcon Wagon Ballast Regulator Actual Exposures identified
Next Steps for Working Group Removing staff not required RPE/PPE Dust suppression units QC/Exposure Monitoring COSHH risk assessment
