Battery Evaluation Accident proneness (HAL 2) is an individual assessment instrument in CEDETI Tablet format developed by UC, which aims to identify individuals who are prone to having accidents. 2 Battery HAL is aimed at evaluating people from years 18 0 months onwards. It is designed to be applied independently and self-guided workers, advancing automatically and successively different types of test. Despite being self-guided, the presence of an evaluator who can help evaluated in case of difficulties is recommended.

As a result of evaluating a single score that discriminates the presence or not of the propensity to accidentarse in each of the workers tested is obtained. This score is called indicator Propensity to Accident (IPA), which allows discrimination in the study population. The IPA is composed of 4 indices: respect for rules, attention to detail, intelligence and attention test errors.
