Fatality (F)
Death from a work-related injury, certified by a medical professional. Fatality Frequency Rate (FFR) is calculated on the number of fatalities per million man hours.
Lost Time Injury (LTI)
Any work-related injury resulting in the employee or contractor not being able to return to work for their next scheduled work period. Returning to work with work restrictions does not constitute a lost time injury status, no matter how minimal or severe the restrictions, provided it is at the employee’s next scheduled shift. However, if an injury deteriorates and time is later lost, an LTI should be recorded. Lost Time Injury Frequency Rate (LTIFR) is calculated as number of Lost Time Injuries per million man hours.
Restricted Work Case (RWC)
Any work-related injury other than a fatality or a Lost Time Injury where the injured person cannot fulfil his normal work the day following the injury but is able to undertake a temporary job, work at his normal job but not full-time, or work at a permanently assigned job but unable to perform all duties normally assigned to it. If the injury has led to lower productivity or slower work from the worker, but the worker is still capable of undertaking all of their routine tasks, then this would not be classified as restricted work.
Medical Treatment Injury (MTI)
Any work-related injury other than a fatality, a Lost Time Injury, or a restricted work case, that resulted in a certain level of treatment (not first aid treatment) given by a physician or other medical personnel under standing orders of a physician (e.g. medical treatments: using prescription medications, or use of a non-prescription drug at prescription strength, Using wound closing devices such as surgical glue, sutures, and staples, Using any devices with rigid stays or other systems designed to immobilise parts of the body, Administration of oxygen to treat injury or illness).
Minor Injury (MI)
Any work-related injury other than a fatality, a Lost Time Injury, a restricted work case, or a Medical Treatment Injury which is treated by first aid or minor manipulation to provide relief for a strain or bruise. A minor injury does not require treatment by a professionally trained paramedic or physician and does not incur loss of work time other than time of the shift on which it occurred. The injured person continues with his normal scheduled work ( e.g. using a non-prescription medication at non-prescription strength, administering tetanus immunisations, cleaning, flushing or soaking wounds on the surface of the skin, using wound coverings such as bandages, Band-Aids™, gauze pads, etc.; or using butterfly bandages or Steri-Strips™, using hot or cold therapy, drilling of a fingernail or toenail, using eye patches).
