[Coronary and vascular pathology in dynamite workers]

Dynamite is at the origin of several pathological processes related to two of its components: nitroglycerin and dinitroglycol. During the various manufacturing phases, these substances enter the body via the lungs or the skin. The most severe disorder remains the wean-off electrical cardiac syndrome with the so-called "Monday morning" sudden death possibility, but asymptomatic myocardial electrical disorders are also reported. Syndromes of permeation and overload essentially result in headaches, peripheral vasodilatation, and Raynaud's phenomenon. Regression of these pathological effects will be obtained through improved collective technical prevention and a broader knowledge of the risks.
