Jednodu\u0161e \u0159e\u010deno, p\u0159it\u00e1hne je k sob\u011b, tak\u017ee uhod\u00ed do n\u011bj, m\u00edsto do n\u011bjak\u00e9ho jin\u00e9ho m\u00edsta na dom\u011b.

T\u00edm je probl\u00e9m v podstat\u011b neutralizov\u00e1n.Ot\u00e1zkou v\u0161ak je, co by se stalo, kdyby tomu tak nebylo. Jist\u011b, m\u016f\u017eeme si myslet, \u017ee to byl probl\u00e9m hlavn\u011b v minulosti, kdy byla v\u011bt\u0161ina dom\u016f a p\u0159edev\u0161\u00edm pak st\u0159ech postaven\u00e1 ze d\u0159eva, a tedy snadno chytila. Dnes m\u00e1me solidn\u00ed cihlov\u00e9 \u010di panelov\u00e9 domy, u kter\u00fdch n\u011bco takov\u00e9ho p\u0159\u00edli\u0161 nehroz\u00ed.

Nesm\u00edme zapom\u00ednat, \u017ee blesk m\u00e1 teplotu okolo 1 000 stup\u0148\u016f Celsia. Je tedy schopen u\u0161kva\u0159it prakticky cokoliv, \u010deho se dotkne.

Pokud uhod\u00ed do domu, tak dok\u00e1\u017ee ve vte\u0159ince nejen doslova u\u0161kva\u0159it na\u0161i elektroinstalaci, ale tak\u00e9 zp\u016fsobit po\u017e\u00e1r spot\u0159ebi\u010d\u016f, kter\u00e9 jsou pr\u00e1v\u011b zapojeny, a\u0165 u\u017e je to po\u010d\u00edta\u010d, televize nebo i ledni\u010dka.
