Risk Assessment Framework for Electric Arc Welders Dr. Liliana Rapas Direction of Public Health Bucharest Dr. Ing. Steluta Nisipeanu National Institute for Research - Development of Labor Protection

Our Experience

*two frameworks: 1. occupational health and safety programmes 2.occupational medicine guidelines Background Regulation

Background Strategy

First study

Second Study 1. The auditors team: occupational physician, welding technology engineer safety engineer 2. The system: workplace where welders are dealing with electric arc welding of stainless steel pieces of food industry technology 3. The method: *occupational medicine surveillance *risk assessment

Documents: 1. Workplace assessment paper based on: * control list of identified and measured hazards * welding tehnology * environment * safety standards requirements 2. The matrix of gravity and frequency of risk health effects based on CEI-812/ Calculated risk level closely linked with safety level

N r = ∑ r i x R i / ∑ r i = 259 : 85 = 3,04 Results:

Distribution of concentration (mg/m 3 ) of gaseous and particulate mixture from“welding fume” oxides of nitrogen manganese iron oxide ozone

Welding Fumes Compounds

Occupational medicine surveillance results: Statistical information: one labor accident and 10 injuries

Our observation: there is no relationship between health condition surveillance’ results and calculated risk Why?

The importance:
