Inspected, or worried about an inspection?
Since February 2025 inspectors apply the DS 44 inspection form. Every missing document, or one citing repealed decrees, is a separate infraction.
Fines range from 3 to 60 UTM per infraction depending on company size, and can double or triple for repeat offences. If you correct within 15 days, they are cut at least in half.

Cases
Illustrative examples based on real, frequent situations in the region’s companies, so you can see how we work.
Illustrative caseA mid-sized construction company received a summons from the Labour Inspectorate. Its internal regulations cited DS 40, there was no job-specific IRL and the joint committee had never been set up.
Result: The company presented the complete folder within the deadline and the inspection closed without a fine. It now keeps a monthly advisory.
Illustrative caseA small transport company accumulated commuting and driving accidents. The insurer had warned that the additional premium could rise at the next assessment.
Result: The accident rate fell steadily over the year and the company reached the DS 67 assessment with a documented management system.
Illustrative caseA maintenance contractor won a contract at a high-altitude mine site. The client demanded a complete start-up folder, MINSAL protocols and altitude exams before entry.
Result: The crew entered the site on the committed date and the folder passed the client’s audits without major observations.

FAQ
Every company, from one worker up, needs an IPER matrix, a preventive work programme, job-specific risk information, training and a Ley Karin protocol. From 10 workers, internal regulations are added and, if there is no committee, a safety delegate. Over 25 workers the joint committee is mandatory. Under 100 you must appoint a trained prevention officer and over 100 a department led by an expert registered with the health authority.
It applies the DS 44 inspection form: internal regulations with signed receipt, job-specific IRL, a current IPER matrix, the preventive programme, joint committee minutes, training and PPE delivery records, an emergency plan with a drill, the Ley Karin protocol and the accident and incident register. It checks validity and evidence, not just existence.
No. DS 44 repealed DS 40 and DS 54 on 1 February 2025. Regulations, an ODI or a programme citing those decrees are outdated and count as non-compliance, even if recently signed.
Only above 100 workers in mining, industrial or commercial companies, where a prevention department with an expert must exist. Below that number the law does not require hiring, but it does require meeting every obligation. That is why most SMEs work with an external safety professional.
Yes, to every employer from one worker up. You must have a protocol for preventing workplace harassment, sexual harassment and violence, a confidential complaint channel and an investigation procedure, even if no complaint has ever been filed.
Your insurer (ACHS, Mutual de Seguridad, IST or ISL) provides technical assistance, courses and templates, and treats accidents and occupational diseases. It does not execute the management inside your company or write your documents to your reality. We do that part, coordinated with your insurer.
For a typical SME, between one and three weeks from the diagnosis, depending on size, risks and what you already have. If you have an inspection deadline, we prioritise what the inspector asks for first.
We serve the whole Valparaíso Region in person: Quilpué, Villa Alemana, Concón, Quillota, San Antonio, Los Andes and surroundings. For the rest of Chile we work remotely with scheduled visits.
If you correct the infraction within 15 days the fine is reduced by at least 50%, and in micro and small companies by at least 80%. There is also a reconsideration appeal within 30 days. We help you regularise in time and present the documentation.
