3.1
trencher
self-propelled crawler or wheeled machine, having a rear- and/or front-mounted equipment/attachment,

4 List of additional significant hazards
See Annex A.
NOTE Annex A (normative) contains all the significant hazards, hazardous situations and events, as far as they are
dealt with in this European Standard, identified by risk assessment as significant for this type of machinery and which
require action to eliminate or reduce the risk.
