What PR OSHA requires of an employer

Last reviewed: August 15, 2026VerifiedDepartamento del Trabajo

In short

Under Puerto Rico’s Occupational Safety and Health Act, employers are responsible for providing their employees a workplace free of hazards and for complying with all PR OSHA safety and health standards. The agency is specific about the order: it requires employers to eliminate or reduce hazards first through changes in working conditions, rather than simply resorting to respirators, gloves, earplugs or other personal protective equipment. Switching to safer chemicals, enclosing processes to capture harmful fumes or using ventilation to clean the air are the examples PR OSHA gives. Employers must also inform employees about hazards, keep accurate records of work-related injuries and illnesses, carry out the testing the standards require, post PR OSHA citations and the PR OSHA poster where workers can see them, and notify PR OSHA within eight hours of any incident resulting in a death or the hospitalization of three or more employees. And no employee may be discriminated against or retaliated against for exercising their rights.

What is it?

Puerto Rico’s Occupational Safety and Health Act, Ley Núm. 16 of 5 August 1975, requires employers to provide their employees with working conditions free of known hazards, and creates PR OSHA to set, adopt and enforce protective standards. Employers must find and correct safety and health problems, situations or hazards. The same law protects workers who complain to their employers, to PR OSHA or to other government agencies about unsafe or unhealthy working conditions. PR OSHA also provides information, training and assistance to workers and employers alike.

Who can do it?

These responsibilities fall on employers and business owners covered by Ley 16 of 1975. As to recordkeeping, PR OSHA specifies that the law requires “certain employers” to prepare and keep records of work-related injuries and illnesses; the page does not publish which employers are exempt or on what criteria, so that has to be confirmed with PR OSHA.

Step by step

  1. Step 1: Fix the condition before handing out equipment

    PR OSHA does not leave this to judgement. It requires employers to eliminate or reduce hazards first through changes in working conditions, rather than simply resorting to respirators, gloves, earplugs or other kinds of personal protective equipment. The agency’s own examples: switching to safer chemicals, enclosing processes to capture harmful fumes, or using ventilation systems to clean the air. Handing out masks is the cheap answer and it is precisely what PR OSHA names as insufficient on its own.

  2. Step 2: Tell people what hazards they face

    You must inform employees about hazards through training, labels, alarms, colour-coding systems, chemical information sheets and other methods. And on the worker’s side, Ley 16 gives them the right to have that training given in a language they can understand.

  3. Step 3: Keep the injury and illness log

    Ley Núm. 16 of 5 August 1975 requires certain employers to prepare and keep records of work-related injuries and illnesses. PR OSHA warns about that form: it contains employee health information and must be used in a way that protects the employee’s confidentiality to the greatest extent possible, while the information is used for occupational safety and health purposes. The forms are in PR OSHA’s Forms and Publications section.

  4. Step 4: Run the testing the standards require

    Carry out workplace testing, such as the air sampling required by some PR OSHA standards, and administer hearing exams or other medical testing the standards require. On the worker’s side, the law gives them the right to observe testing done to find hazards and to obtain the results.

  5. Step 5: Post what has to be posted

    Post PR OSHA citations, the occupational injury and illness logs and the PR OSHA poster in the workplace, where workers can see them. It is not decoration: it is how the law makes sure people know what has been cited and what has happened at that site.

  6. Step 6: Eight hours if there is a death or three hospitalized

    This is the number to have written on the wall. You must notify PR OSHA within eight hours of its occurrence of any incident resulting in a death or the hospitalization of three or more employees. Eight hours from when it happens, not from when the response gets organized.

  7. Step 7: Do not punish whoever complains

    You may not discriminate or retaliate against any employee for exercising their rights under the law. The Occupational Safety and Health Act protects workers who complain to their employers, to PR OSHA or to other government agencies about unsafe or unhealthy working conditions. A worker cannot be transferred, denied a raise or have their hours cut for that; and the employee has 30 days from learning of the action to file a discrimination complaint.

Where to do it

PR OSHA is part of the Department of Labor and Human Resources and maintains a Central Office and Area Offices, whose details it publishes in its Contact section. Its email is prosha@trabajo.pr.gov. The standards, regulations and recordkeeping forms are in the Standards and Regulations and Forms and Publications sections of its page.

What to do if something goes wrong

If your answer to a hazard was buying personal protective equipment, PR OSHA regards that as insufficient on its own: changing working conditions has to be tried first. If you do not know whether your business is among the employers required to keep the injury and illness log, the page only says “certain employers” and does not publish the criterion: ask PR OSHA. If an employee has complained, you cannot punish them, and they have 30 days to file a discrimination complaint if you do. This guide does not list the technical standards applicable to each industry, the fines, or the citation and answer procedure: PR OSHA does not publish that on these two pages, though it does maintain a Standards and Regulations section and Federal Register translations. PRFácil gives no legal advice.

Common mistakes

  • Answering a hazard by handing out masks, gloves or earplugs without changing the condition causing it.
  • Letting more than eight hours pass before reporting a death or the hospitalization of three or more employees.
  • Not posting the PR OSHA poster or citations where workers can see them.
  • Keeping the injury log without protecting the confidentiality of the employee’s health information.
  • Training in a language the worker does not understand.
  • Transferring, denying a raise to, or cutting the hours of whoever complained.
  • Assuming your business is exempt from the injury log without confirming it with PR OSHA.

Frequently asked questions

When must I call PR OSHA about an accident?

Within eight hours of the occurrence, when the incident results in a death or the hospitalization of three or more employees.

Is giving them protective equipment enough?

No. PR OSHA requires employers to eliminate or reduce hazards first through changes in working conditions, rather than simply resorting to respirators, gloves, earplugs or other kinds of personal protective equipment.

Do I have to keep an injury log?

Ley Núm. 16 of 5 August 1975 requires certain employers to prepare and keep records of work-related injuries and illnesses. PR OSHA’s page does not publish which employers fall outside that, so confirm it with the agency.

Can I fire someone who complains to OSHA?

No. It is against the law for an employer to fire, demote, transfer or discriminate against a worker for having filed a complaint or exercised another right under the law, nor may they be denied a raise or have their hours cut for that reason.
