Quantitative Analysis of the Factors that Influence Welding Fume Exposure via ART Modelling

Area of Science:

• Occupational Health and Safety
• Industrial Hygiene
• Environmental Science

Background:

• Industrial welding operations generate fumes that present significant health hazards.
• Building materials enterprises face risks associated with welding fume exposure.

Purpose of the Study:

• To investigate factors influencing welding fume exposure in building materials enterprises.
• To analyze key parameters using the Advanced REACH Tool (ART) for dust exposure assessment.

Main Methods:

• Compared ART model assessments with measured dust exposure data from 18 enterprises.
• Utilized multiple covariance analysis to identify influencing factors.
• Employed correlation and regression analyses to evaluate factor-exposure relationships.

Main Results:

• The ART model demonstrated high agreement with field data at the 95th percentile.
• Identified moisture content, surface contamination/emissions, and dust particle size as primary influencing factors.
• Established relationships between these parameters and overall dust exposure levels.

Conclusions:

• Prioritized control of moisture content is crucial for mitigating occupational health risks.
• Dust particle size and surface contamination/emissions are also key targets for risk reduction.
• Implementing targeted control strategies for these parameters can effectively reduce welding fume exposure risks.
