Intervention Measures

Educational Experience  Sep Jul Jiangxi Medical College Major: Preventive Medicine Degree: B.S. Sep Jul School of Public Health, Fudan University(Pre-Shanghai Medical University) Major: Toxicology Degree: M.S.

Professional Experience 2005~ Occupational Health and Poisoning Control Department of Shanghai CDC Emergency Disposal for occupational poisoning  Surveillance and Epidemiological Investigation for occupational poisoning

Current Research Occupational Risk Management Toolbox, Control banding The approach groups workplace risks into" control bands” based on combinations of hazard and exposure information It can also be applied to chemicals and non- chemical workplace hazards

Identify the hazard Using R-Phrases Quantity: small, medium or large One of 4 broad Control approaches Dustiness or Volatility Detailed guidance for each task How often the task is Done and for how long HOW DOES IT WORK?

35KN GENERAL VENTILATION A good standard of general ventilation 2 - ENGINEERING CONTROL Typically LEV ranging from single point extract close to the source of hazards, to a ventilated partial enclosure 3 - CONTAINMENT Hazard is contained, or enclosed, but small- scale breaches of containment may be acceptable 4 - SPECIAL Expert advice needed - seek further help Special help needed Least reduction in exposure Greatest reduction in exposure THE FOUR CONTROL APPROACHES
