What is preventive competence?
A person is competent for a role when they can apply the necessary knowledge and skills under the conditions for which they have been trained. In occupational health and safety (OSH), this means recognizing relevant hazards, using the established controls, understanding the limits of their actions, and knowing when to stop or ask for help. Competence always requires a scope: general experience alone does not make one competent for any task.
A distinction must be made between an individual’s competence and the adequacy of working conditions. Even a well-prepared person can be vulnerable if safeguards, time, or adequate resources are lacking. Analyzing a failure solely as “lack of attention” or “lack of training” can mask underlying organizational causes. Competence is an integral part of the preventive system, along with task design and risk management.
Training, competence and authorization
Occupational safety and health (OSH) training is one way to develop competence. It can provide knowledge, practice, and decision-making criteria, but attendance or passing a theoretical exam does not guarantee that the person will apply what they have learned. Experience also contributes, although it can reinforce unsafe habits if no one challenges them.
Authorization is an organizational decision that enables individuals to perform specific tasks within its rules and applicable requirements. It should not be confused with competence or professional certification required by law. An internal record does not replace degrees, licenses, or other legally required qualifications. It is advisable to separately identify the specific training, evaluation, and authorization required for each activity.
How to define the requirements
The requirements stem from the actual work, risk assessment, and assigned responsibilities. They must consider normal operations, format changes, cleaning, maintenance, and foreseeable deviations. A generic description like “know the risks of the position” is of little use if it doesn’t specify which behaviors or decisions need to be checked.
For a warehouse task, for example, these requirements might include recognizing routes, maintaining pedestrian separation, detecting relevant damage, and reporting unsafe conditions. For a manager, they might include preparing for an activity and resolving priority conflicts. The training and development matrix helps link these requirements to people and evidence, without reducing them to a mere list of courses.
Learning and adapting to people
Learning should combine clear explanations, demonstrations, and sufficient practice for the activity. It is adapted to the language, prior experience, and comprehension needs of the learner, without assuming that handing over a manual is equivalent to teaching. The learner’s questions allow for the discovery of ambiguities or discrepancies between the instructions and the actual operation.
For tasks with significant risks, practice should be organized under controlled conditions and with adequate supervision. Exposing someone to a hazard to test their reaction is not appropriate. When a situation cannot be safely replicated, simulations or decision-making scenarios can be used, clearly indicating which aspects of competence can be assessed and which require further evidence.
How to verify competence in practice
The assessment is designed before the training is considered complete. It can combine questions, demonstrations, supervised observation, and problem-solving exercises. The criteria must be clearly defined and focus on safety-related aspects. An assessment based solely on speed of execution could reward shortcuts that are incompatible with the intended controls.
The evaluator needs the competence to judge the task and record any observed limitations. The conclusion should clearly state the scope of work performed, the conditions, and any outstanding needs. If someone correctly performs a routine task, it should not be automatically assumed that they can handle breakdowns or modifications. The supervisor’s personal confidence in the task must be based on evidence and consistent criteria.
Practical example
A worker receives training on how to use equipment and answers a questionnaire correctly. During supervised practice, she identifies a normal shutdown, but does not distinguish between a production stoppage and a safe condition for accessing a hazardous area. The questionnaire tested vocabulary, while the practice reveals a specific learning need.
The company reinforces the explanation and demonstration, verifies that the instructions are clear, and rechecks the worker’s performance within the permitted scope. Interventions requiring isolation are reserved for trained and authorized personnel. The final record describes the tasks verified and their boundaries; a generic authorization covering operations that have never been evaluated is not used.
When to reassess competence
Competence should be reviewed when equipment, procedures, risks, or responsibilities change, and when experience reveals difficulties in implementation. It may also require attention after extended periods of inactivity. OSH change management should consider these needs before implementing the modification.
The repetition of an error does not, in itself, prove that the same course needs to be offered again. It may reveal contradictory instructions, an impractical design, or time pressure. These causes should be analyzed in conjunction with individual preparation. The review should produce an appropriate response to the problem, which may include technical or organizational changes in addition to learning.
Evidence, responsibility and legal framework
The evidence may include content, practice, evaluation, scope, and date, along with the identity of the person who prepares and verifies it. It must be provided to and accessible to those who organize the tasks. The records need not include personal assessments unrelated to the role, nor should they become a permanent system for labeling individuals.
In Spain, Law 31/1995 regulates training and preventive information, placing protection within the scope of employer responsibility. Training requirements vary according to job function and specific regulations. Information provided to workers complements training but does not replace it. OSHA guidelines offer criteria for learning and participation, without superseding the obligations of each jurisdiction.
