Figure 1 — Main parts of a loader crane 4 List of significant hazards Table 1 shows a list !deleted text" of significant hazardous situations and hazardous events that could result in risks to persons during intended use and foreseeable misuse. It also contains corresponding cross-references to the relevant clauses in this European Standard that are necessary to reduce or eliminate the risks associated with those hazards. Before using this European Standard it is important to carry out a risk assessment of the crane. As a minimum the hazards covered by Table 1 should be included in the risk assessment.
