Never let your company's IPER risk matrix miss its annual review
Every employer reviews its hazard identification and risk assessment matrix (IPER) at least once a year, and also after changes at work, accidents, occupational diseases or a serious and imminent risk (DS 44 of 2024, Article 7). After each update the preventive work programme is adjusted within 30 days.
Supreme Decree 44 of 2024 of Chile's Ministry of Labour and Social Security, in force since 1 February 2025, regulates the preventive management of occupational risks. Every employer must draw up a matrix identifying hazards and assessing the occupational risks associated with its processes, tasks and jobs; the matrix must be available at the workplaces and communicated to workers, including the Joint Committee, the Occupational Safety and Health Delegate and union officers (DS 44, Article 7). To draw it up the employer considers the risk agents and factors present, such as ergonomic and psychosocial risks, violence and harassment at work, past occupational accidents and diseases, and risks linked to occupational health surveillance programmes, with a gender perspective (Article 7).
The matrix contains, as a minimum, the identification of the hazards of each job and the assessment of the risks, taking into account foreseeable conditions and especially sensitive workers; the assessment procedure follows the Technical Guide of the Public Health Institute or the document that replaces it, unless a rule requires a special methodology (Article 7). The matrix must be known to the whole management line and reviewed at least annually or whenever working conditions change in a way that may create additional risk, an occupational accident occurs, an occupational disease is diagnosed or a serious and imminent risk arises; to draw it up and review it the company may ask the Law 16.744 insurance administrator for technical assistance (Article 7).
Based on the matrix, the employer draws up or modifies the preventive work programme within 30 calendar days of the matrix being drawn up or updated; the programme states the preventive and corrective measures, their deadlines and the persons responsible, is in writing, is approved by the legal representative with the date of approval and of any changes, is publicised at the workplaces and is sent to the Joint Committee (Article 8). At least once a year the company evaluates compliance with the programme (Article 14). All risk-management information must be recorded and backed up in documents, preferably electronic, available to the enforcement body and the insurance administrator (Article 72).

| Rule | DS 44/2024 of the Ministry of Labour and Social Security, in force since 1 February 2025 (first transitional article) |
|---|---|
| Who draws it up | Every employer, for its processes, tasks and jobs (Article 7) |
| Review | At least annually (Article 7) |
| Extraordinary review | When working conditions change with additional risk, an occupational accident occurs, an occupational disease is diagnosed or there is a serious and imminent risk (Article 7) |
| Prevention programme | Drawn up or modified within 30 calendar days of the matrix being drawn up or updated (Article 8) |
| Programme evaluation | At least annual (Article 14) |

While the matrix and the programme are still being drawn up, the employer must nevertheless inform each worker of the risks inherent in the activity (Article 15). The assessment may use quantitative or qualitative methods, always with a validated methodology based on criteria set by the competent authority (Article 7).
Who is responsible?
The employer is the party required to draw up, communicate and review the matrix (DS 44, Article 7) and to draw up or modify the preventive work programme within 30 days (Article 8), as part of its general duty to protect workers' lives and health effectively (Article 4). It may ask the Law 16.744 insurance administrator for technical assistance (Article 7). In practice the Risk Prevention Department or the safety officer keeps the date of the next review.
If the deadline passes
Inspection, enforcement and sanctioning of breaches of DS 44 at workplaces fall to the Regional Ministerial Health Secretariats and the Labour Directorate, according to their legal powers, without prejudice to the powers of the Social Security Superintendency (Article 77). An unreviewed matrix also drags the preventive work programme behind, since it must be updated within 30 calendar days of each update of the matrix (Article 8), and leaves the documentary record that inspectors may request without support (Article 72).
The annual review is a minimum, not the only trigger
Besides the annual deadline, the matrix must be reviewed whenever working conditions change in a way that may create additional risk, an occupational accident occurs, an occupational disease is diagnosed or a serious and imminent risk arises (DS 44, Article 7). Each extraordinary review restarts the 30-day period to adjust the prevention programme (Article 8). Record the date of the last effective review and, if an event forced an earlier review, update the expiry date.
