Table 8 Small Business Exposure Index Area Summary Scores: Explanation and Observed Frequencies (N = 149)

From: A hazardous substance exposure prevention rating method for intervention needs assessment and effectiveness evaluation: the Small Business Exposure Index

Score Definition: Explanation Intervention Recommendations in Order of Preference N %
1 Material Potential low: Because the materials used have low inherent toxicity, Process Potential and Human Interface are of minimal concern. • Minimal 64 42.9
2 Material Potential medium or high, but Process Potential low: Because there's limited potential for exposure from the process in question, then there's minimal potential for worker exposure at the Human Interface. • Reduce Material Potential
• Improve Engineering Controls
23 15.4
3 Material Potential medium or high, Process Potential medium or high, but Engineering Controls high: Material and Process Potential are significant or of concern, but well-addressed by permanent exposure controls. • Reduce Material Potential
• Reduce Process Potential
40 26.8
4 Material Potential medium or high, Process Potential medium or high, Engineering Controls low or medium, but Human Interface low: Material and Process Potential significant or of concern, but offset by low potential for exposure at the Human Interface. • Reduce Material Potential
• Reduce Process Potential
• Improve Engineering Controls
7 4.7
5 Material Potential medium or high, Process Potential medium or high, Engineering Controls low or medium, Human Interface medium or high, but PPE high: Material and Process Potential significant, and matched with inadequate permanent exposure controls and an over-reliance on control at the worker through PPE. • Reduce Material Potential
• Reduce Process Potential
• Improve Engineering Controls
• Reduce Human Interface Potential
• Rely less on PPE
14 9.4
6 All Potentials medium or high, and Engineering Controls and PPE low or medium: Exposure potential likely to be inadequately matched by protective measures. • Reduce Material Potential
• Reduce Process Potential
• Improve Engineering Controls
• Reduce Human Interface Potential
• Rely on PPE only as a temporary stopgap measure
