Summary
Roofing workers face a heightened risk of peripheral neuropathy due to solvent exposure, particularly n-hexane found in one-ply roofing systems. Abnormal nerve function was detected in a significant percentage of roofers, indicating potential occupational hazards.
Area of Science:
- Occupational Health
- Neurology
- Environmental Medicine
Background:
- Roofing work involves exposure to various chemical solvents.
- One-ply roofing systems are commonly used and may contain specific solvents like n-hexane.
- Peripheral neuropathy is a neurological condition affecting nerves outside the brain and spinal cord.
Observation:
- A 52-year-old roofer developed peripheral neuropathy after exposure to multiple solvents.
- Forty roofers were assessed for symptoms, occupational history, physical examination, and vibrotactile thresholds.
- Exclusion criteria were applied to remove individuals predisposed to peripheral neuropathy.
Findings:
- Abnormal vibrotactile thresholds, indicative of nerve damage, were found in 42% of dominant toes and 36% of nondominant toes (p < .001).
- Fewer roofers exhibited abnormal sensory physical examinations or reported neuritic symptoms.
- A significant association was observed between roofing work and peripheral neuropathy.
Implications:
- Roofing workers may be at increased risk for developing peripheral neuropathy.
- Solvent exposure, especially to n-hexane in one-ply roofing systems, is a potential cause.
- Further research and protective measures are warranted to mitigate occupational risks for roofers.
