Abstract (EN): Working accidents are due to several factors which include collapse of structures, lack ofproper safety training and unrealistic risk assessment. The opening of a trench in ¿urban¿ spaces usuallydon¿t have a great complexity which in many cases leads to a lightening prevention measures causing mortalaccidents. This paper presents the results of the assessment by tree different methods (William Fine,NTP-330, MIAR), one of them in an development stage (MIAR). The same activity was evaluated byfifteen Safety Experts using the tree methodologies. This study concluded that: (a) MIAR methodologyallows identify hazards and determine risk assessment minimizing the subjectivity factor of the applier;(b) provides truthful results and it is adjusted to the real activities of trench opening works; (c) it is influencedby specific criteria for each activity such as exposure time and impact extension. © 2015 Taylor & Francis Group, London.
