Never let a semester pass without solar UV training

Employers with workers exposed to solar UV radiation must keep a written training programme of at least one clock hour every six months on the risk and preventive measures (DS 594, Article 109 b, letter e). Exposed means working in direct sun from September to March, 10:00 to 17:00, or at a UV index of 6 or more.

Law 20.096 requires employers, without prejudice to Article 184 of the Labour Code and Article 67 of Law 16.744, to take the measures needed to protect workers effectively when they may be exposed to ultraviolet radiation; employment contracts or internal rules must specify the use of protective equipment, in line with the Regulation on Basic Sanitary and Environmental Conditions in Workplaces (Law 20.096, Article 19). That regulation is Supreme Decree 594 of 1999 of the Ministry of Health, whose Articles 109 a to 109 c on solar ultraviolet radiation were added by Decree 97 of the Ministry of Health, published in the Official Gazette on 7 January 2011.

Workers count as exposed if they work under direct sunlight between 1 September and 31 March, between 10:00 and 17:00, or if they regularly work under direct solar UV radiation with a UV index of 6 or more at any time of year (DS 594, Article 109 a). Their employers must manage the risk: inform workers using the wording set in the regulation, post the UV index forecast by the Chilean Meteorological Directorate and the control measures in a visible place every day, identify exposed workers and apply engineering, administrative and personal protective measures (DS 594, Article 109 b).

They must also maintain a theoretical and practical training programme for workers lasting at least one clock hour per semester, covering the risk and health consequences of solar UV exposure and preventive measures, among other topics. The programme must be in writing (DS 594, Article 109 b, letter e).

Article 109 b requires at least one hour in each semester; the regulation does not say whether this means calendar half-years or six-month periods from the last session. Recording the next session six months after the previous one meets the rule either way.

Who is responsible?

The duty lies with the employer of the exposed workers, who must manage the UV radiation risk and maintain the training programme (DS 594, Article 109 b; Law 20.096, Article 19). The specific control measures must follow the Ministry of Health's Technical Guide on Solar UV Radiation (DS 594, Article 109 b, letter d).

If the deadline passes

Compliance with DS 594 is enforced by the health authority, in line with the Ministry of Health's rules and instructions (Article 2), and breaches are penalised after formal proceedings under Book Ten of the Health Code (Article 131). Without a training session recorded in the semester, the employer cannot show the written programme required by Article 109 b.

Not the same as the general DS 44 training

Supreme Decree 44 of 2024 also requires general risk prevention training of at least 8 hours, at the frequency set in the preventive work programme, which may not exceed two years (DS 44, Article 16). That is a separate obligation: the DS 594 solar UV training has its own six-monthly minimum, so it is best recorded as a separate date.

Tracking it with ExpirySuite

Add the training programme for each worksite or group of exposed workers and record as the expiry date six months after the last session.
Email reminders arrive 60, 30, 14, 7 and 1 day before expiry and on the expiry day, leaving time to schedule the session before the period of highest radiation.
The prevention officer or trainer can upload the attendance record and written programme through a secure link that is valid for 14 days and needs no account.
Assign a responsible person, such as the risk prevention officer; if the training is overdue, managers get further reminders 3, 7 and 14 days later.
