Task: Translation
Input (English): The controls must also be carried out in such a way that the inspector does not just go on board and check whether there are any fire extinguishers missing, rather there must be materials testing, for this ship obviously broke up on account of material fatigue.
Output (Spanish): Y los controles no deben consistir en que el inspector se limite a subir a bordo y comprobar que no falte ningún extintor, sino que debe realizarse un examen de los materiales, pues este buque al parecer se partió debido a la fatiga de los materiales.
