The reported association of ALS with EMF is generally weaker than that with electrical occupations.
128 ALS has been associated with "electrical" occupations, 129, 130 especially welding.
These accidents and deaths occurred mainly at homes and also at work especially in the electrical construction occupation.

Our study corroborates previous findings that agricultural occupations, occupations in medicine and health, electrical assembling installing and repairing occupations, and occupation as waiters and bartenders are associated with increased risk of UBC, particularly when duration of employment is 10 years or more.
Occupations in electrical work have been implicated in the development of ALS in a few studies (Deapen and Henderson 1986; Gunnarsson et al. 1992).
Borderline significant associations were observed for occupations in electrical assembly, installation and repair (OR 1.69; 95% CI 0.99 to 2.89), law and jurisprudence (OR 1.89; 95% CI 0.90 to 3.95), and food and beverage preparation, and service (OR 1.82; 95% CI 0.91 to 3.66).
Significantly elevated risk of UBC was also evident among those employed for 10 years or more in occupations related to electrical assembly, installation and repair (OR 4.37; 95% CI 1.62 to 11.77), bench work (OR 4.76; 95% CI 1.74 to 13.01), medicine and healthcare (OR 3.07; 95% CI 1.47 to 6.40), and structural work (OR 1.85; 95% CI 1.16 to 2.95).
*Adjusted for age gender and smoking status We observed a significantly elevated risk of UBC among waiters and bartenders, occupations related to electrical assembly, installation, and repair, workers in agriculture production livestock and animal specialties, agricultural production of crops, plant farmers, and employees in medicine and health services.
