Occupational Injury Rate

What the occupational injury rate is

The occupational injury rate (معدل إصابات العمل), also called the injury frequency rate, is an indicator that measures the number of work injuries recorded in an establishment over a period, relative to the amount of exposure to work in the same period.

It is a management indicator, not a legal ruling. An establishment calculates it for itself, to see which way its prevention performance is moving. The Saudi Labor Law (نظام العمل) attaches its provisions to the injury itself and to what follows from it, and in its chapter on work injuries we found no provision that attaches any consequence to a rate calculated from those injuries.

What counts as a work injury in the occupational injury rate

Before any rate is calculated, the numerator has to be agreed. What counts as a work injury is not something an establishment defines internally, and the Labor Law does not define the term in its text either. It refers out:

• Article 134 of the Labor Law. It provides that an injury is a work injury as defined in the Social Insurance Law (نظام التأمينات الاجتماعية), that occupational diseases rank as work injuries, and that the date of the first medical observation of the disease ranks as the date of injury.
• Article 135 of the Labor Law. It ranks a relapse, or any complication arising from it, as the injury, and applies to it the rules on aid and treatment that apply to the original injury.
• Article 136 of the Labor Law. It refers occupational diseases to the schedule of occupational diseases (جدول الأمراض المهنية) in the Social Insurance Law, and degrees of disability to the disability percentage schedule (جدول دليل نسب العجز) in that same law. Neither schedule is part of the Labor Law, and we do not reproduce either. How the disability schedule enters compensation is described under partial disability.

The effect of Article 134 of the Labor Law on measurement is direct. An occupational disease enters the count, and it is recorded on the date of its first medical observation, not on the date exposure began. A relapse is ranked by Article 135 of the Labor Law as the original injury rather than as a new event, so an establishment that records it as a second injury counts one case twice. The obligations that a single injury places on the employer are set out under work injury.

Article 132 of the Labor Law and the occupational injury rate

Article 132 of the Labor Law provides that the provisions of its chapter on work injuries, Articles 132 to 141 of the Labor Law, do not apply to establishments subject to the occupational hazards branch (فرع الأخطار المهنية) of the Social Insurance Law.

That provision comes before anything said about the compensation in Articles 137 and 138 of the Labor Law. An account that presents those Articles as what an injured worker in the private sector receives, without first stating Article 132 of the Labor Law, can answer a question about a situation that is not the reader’s. Which establishments fall inside the chapter and which fall outside it is a legal question, and the definition of the occupational injury rate does not settle it. The branch, and the social insurance system that contains it, have their own provisions in the Social Insurance Law.

How an occupational injury rate is built

The figure depends on five decisions, and each of them can be recorded in writing before the first calculation is made.

1. Fix the numerator with a written rule. It settles whether only the cases that caused absence from work are counted, or also the cases that were treated without any absence. Both rules are legitimate, but comparing a figure built on one with a figure built on the other is not.
2. Measure the denominator as exposure, not as headcount. The hours actually worked in the period reflect exposure more closely than the number of employees, because an employee who works part time and a seasonal contractor are not exposed to the same extent as a permanent employee who works full time. Where hours are not available, headcount can first be converted into full time equivalents.
3. State the base that the rate is expressed against, and give it beside the figure every time. A rate with no stated base is a number without meaning, and it cannot be compared with the figure of another establishment that used a different base.
4. Examine it alongside a severity indicator. A count of injuries does not distinguish a superficial cut from a permanent disability. The working days lost per injury are therefore examined alongside the rate; without them, the rate can fall while the harm rises in the same period.
5. Break it down by site, by shift and by task. An overall rate can conceal a concentration of injuries at one site or on the night shift, and it is that concentration, not the overall figure, on which a decision can be based.

The same discipline applies within one establishment over time. If the numerator rule or the base changes between two years, the figure changes because of the method rather than the workplace, so a change of rule is recorded together with the date on which it took effect.

The base of an occupational injury rate

In the sources we reviewed, we found no single approved numerical base for the occupational injury rate. More than one base is in use in international practice, and because the bases differ, the same record of injuries can appear as two different values. An establishment that compares its rate with a published rate without checking the base behind it is comparing two numbers that do not measure the same thing. The definition of the occupational injury rate prefers no base over another, and attributes none of them to any body.

Reporting deadlines and the occupational injury rate

Article 141 of the Labor Law provides that the procedures for reporting work injuries are set by a decision of the Minister, and Article 141 of the Labor Law sets no deadline itself. In the sources we reviewed, we did not locate a standalone ministerial decision issued under it. The Implementing Regulation (اللائحة التنفيذية) does execute it: Article 28 of the Implementing Regulation requires the employer to report a worker’s injury to the competent labour office within a week of learning of it, and that provision applies only to an establishment that is not subject to the occupational hazards branch of the Social Insurance Law. For establishments within the branch, the reporting route has its own provisions in the social insurance law that governs them: under the Social Insurance Law (Royal Decree M/273) Article 30/4 refers the methods and deadlines to its Executive Regulation, whose Article 46/2 requires the employer to notify the General Organization for Social Insurance (GOSI) of work injuries that first aid does not suffice for within 3 days of being notified or learning of the injury; we state no period for workers who remain under the earlier M/33 system. No rule on it is drawn from the definition of the occupational injury rate.

A different one week deadline appears in Article 166 of the Labor Law. It is a separate duty: notifying the competent labour office of every young person (حدث) the employer employs, within the first week of their employment. Article 166 of the Labor Law concerns the employment of young persons, not injuries, and its deadline is not carried over to injury reporting.

Recorded duties that sit alongside the occupational injury rate

Article 143 of the Labor Law requires the employer to entrust one or more doctors with a comprehensive examination, at least once a year, of its workers who are exposed to one of the occupational diseases listed in the schedules of the Social Insurance Law, and to record the result in its registers and in those workers’ files. What such a file holds, and how it is organised, is described under employee file.

Article 133 of the Labor Law requires the employer to treat a worker who suffers a work injury or an occupational disease, and to bear all the necessary costs, directly or indirectly, including a stay in hospital, medical examinations and laboratory tests, radiology, prosthetic devices and the cost of transport to the places of treatment. That duty applies within the scope that Article 132 of the Labor Law has not excluded from the chapter.

How the occupational injury rate can be distorted

A low rate can mean good prevention, but it can also mean that reporting has stopped. Linking bonuses or the appraisal of supervisors to a falling rate can lead to the second. What is then measured is not safety but silence, and the cost can surface later in a single severe injury with nothing before it in the record.

Indicators of near miss reporting are examined alongside the occupational injury rate, not in place of it. Collecting and reviewing those reports is work that an establishment can assign to a safety committee or to a health and safety officer, so that the record of what nearly happened is kept with the same care as the record of what did.

Sources for the occupational injury rate provisions

The provisions relied on are those of the Saudi Labor Law as published by the Ministry of Human Resources and Social Development: Article 132 (the exclusion of establishments in the occupational hazards branch), Article 133 (treatment at the employer’s cost), Article 134 (the definition of a work injury and the date of an occupational disease), Article 135 (relapse), Article 136 (the two schedules), Article 141 (reporting procedures), Article 143 (the annual examination and its record) and Article 166 (notification of young persons employed). Article 28 of the Implementing Regulation is relied on for injury reporting outside the occupational hazards branch, and Article 30 of the Social Insurance Law (Royal Decree M/273) with Article 46 of its Executive Regulation for reporting within it. Royal Decree M/44 of 1446H, in force since 19 February 2025, did not amend Articles 132 to 136, 141, 143 or 166 of the Labor Law.
