Definition(s)
Occupational Injuries
An occupational injury is any injury which results from a work incident or from a single instantaneous exposure in the work environment. Conditions resulting from one-time exposure to chemicals or the aggravation of pre-existing medical conditions or previous injuries are also considered to be injuries. Injuries and fatalities that occur while the worker is onsite at the offshore installation or vessel and off duty/off-shift are included. Self-inflicted injuries or fatalities are not included. Note: IRF (www.irfoffshoresafety.com/country/performance/scope.aspx); OSH 15.1 and OSH (NS) Element 2, Part 15, Section 15.1. Injuries that occur while a person is in transit to and from the offshore installation, vessel or aircraft are included (i.e. from the time a person boards a support craft prior to their hitch to the time they debark the support craft at the end of their hitch). There are four classifications of occupational injury for the purpose of these guidelines. They are as follows: Major Injury An occupational injury that results in one or more of the following: • Amputation: Includes whole or partial amputation of parts of the body (does not include loss of fleshy tip of finger, nail, or tooth); • Skeletal injuries: Includes bone fractures (including chipped or cracked bone or hairline fracture) and dislocation of shoulder, hip, knee or spine. They do not include fractures to fingers, toes, or a broken nose; • Burns: Only if the injured person becomes unconscious, is admitted to the hospital, or requires resuscitation; • Injuries to internal organs: Only if the injured person becomes unconscious, is admitted to the hospital, or requires resuscitation; • Eye injuries resulting in loss of sight (permanent or temporary); • Eye injuries resulting from a penetrating eye injury or a chemical or hot metal burn to the eye; • Any acute illness caused by exposure to chemicals or biological agents or anything that produces a significant negative physiological effect e.g. decompression illness, loss of hearing, and radiation sickness; • Hypothermia or heat induced illness (unconsciousness); • Any injury resulting in unconsciousness, resuscitation, or admittance to the hospital. Note: IRF (www.irfoffshoresafety.com/country/performance/scope.aspx). Lost/Restricted Workday Injury An occupational injury other than a “Major Injury” which results in a person being unfit for work on any day after the day of occurrence of the injury or unfit for full performance of the regular job on any day after the injury. Any day includes rest days, weekend days, leave days, public holidays, or days after ceasing employment.

Medical Treatment Injury Cases that are not severe enough to be reported as lost/restricted workday cases but are more severe than requiring simple first aid treatment are considered to be medical treatment injuries. Note: IRF (www.irfoffshoresafety.com/country/performance/scope.aspx); OSH (NL) 15.1 and OSH (NS) Element 2, Part 15, Section 15.1. First Aid Injury Cases that are not sufficiently serious to be reported as medical treatment or more serious cases but nevertheless require minor first aid treatment, e.g. dressing on a minor cut, removal of a splinter from a finger are considered to be first aid injuries.

Regulatory GuidanceMajor Impairment/Damage
Definition(s)
Major Impairment/Damage
All damages or impairments that compromise the ongoing integrity or emergency preparedness (from a safety or environmental perspective) of an offshore installation, vessel or aircraft are considered reportable. Note: IRF (www.irfoffshoresafety.com/country/performance/scope.aspx); OSH 15.4 (NL), OSH (NS) Element 2, Part 15, Section 15.4; INST 67 and 70; DPR 76. This includes the impairment of critical systems but does not include the impairment of individual pieces of equipment, unless collectively or individually they have the ability to impair all or part of a critical system. It does not include the reporting of damage or impairment to equipment where there are redundant systems in place such that functionality and availability of the system is not lost. Any damage or impairment, which results in production shut-in or drilling suspension, is considered reportable. In addition, any damage or impairment to environmentally critical equipment, which results in the inability to meet established limits, is considered reportable. Some examples of major impairment/damages include (but are not limited to): • Loss of mooring, stability or buoyancy • Failure in dynamic positioning systems • Impairment of fire protection system • Explosion, collapse or bursting of any closed vessel or associated pipework. • Impairment of waste treatment system • Loss or damage to a support craft • Failure of any load-bearing parts and critical components of cranes or elevating devices • Structural damage to structures from impact, erosion, corrosion or cracks • Total power failure, coupled with a start failure of emergency power generators.

Definition(s)
Impairment/Damage to Critical Equipment
All impairments to at least one piece of safety or environmentally critical equipment on an offshore installation, vessel or aircraft shall be reported via the written notification process described in Section 5.3.3. Note: 72 OSH 15.4 (NL), OSH (NS) Element 2, Part 15, Section 15.4; INST 67 and 70; DPR 76. This does not include the reporting of safety or environmentally critical equipment which has been taken out of service for planned inspection, testing and/or maintenance, unless it is out of service for a period longer than its expected unavailability period as determined by the installation’s safety plan. If the damage or impairment compromises the ongoing integrity or emergency preparedness of an offshore installation, vessel or aircraft, then it should be reported as a “Major Impairment/Damage”. Some examples of impairments include, but are not limited to: • Failures or unsuccessful tests of the safety system of a production installation or of any component of the safety system. Note: DPR 76; INST 67. • Impairment of firefighting or lifesaving equipment • Failure of load bearing parts of containers, lifting devices, elevating devices or loose lifting gear • Failure of primary and/or secondary retention of equipment at height • Damage to subsea equipment.

Regulatory GuidanceHydrocarbon Release
Definition(s)
Hydrocarbon Release
Hydrocarbon release refers to an unintentional or uncontrolled release of gas or liquid hydrocarbons from the processing, storage or offloading systems on a production or drilling installation. A hydrocarbon release does not include releases that result from processes designed into the production and processing systems to respond to upset conditions (e.g. blowdown system). Note: IRF (www.irfoffshoresafety.com/country/performance/scope.aspx). Two types of hydrocarbon releases shall be reported: A Major Hydrocarbon Release is defined as: • A gas release rate above 1 kg/sec for at least 5 minutes duration • The amount of gas released is greater than 300 kg or • The amount of liquid released is greater than 300 L. A Significant Hydrocarbon Release is defined as: • A gas release rate between 0.1 kg/sec and 1 kg/sec and lasts for 2 to 5 minutes • The amount of gas released is between 1 kg and 300 kg or • The amount of liquid released is between 5 L and 300 L.
