HSE Terms and Definitions

No. of Workers: This is the total workers averaged per day. This must also include all the subcontractors and office staff working for that particular project.

Man-hours Worked: Employees hours shall be calculated from the payroll or time clock records. When this is impossible, the hours can be estimated by multiplying the total employee days worked for the period covered by numbers of hours worked per day. If the hours worked per day vary among departments, separate estimates must be made for each department and the results added together. The total number of employee days for the period is the sum of the numbers of employees at work on each day of the period. When actual employee hours are not used, indicate the bases on which the calculation is made. The total hours worked also includes overtime and training but excludes leave and sickness, by employees engaged in the activities of the organization in the period under review.

Fatalities: Any death arising from a work related injury or illness, regardless of the time interval between when the injury or illness occurred and death.

Permanent Total Disabilities: Any work-related injury or illness which permanently incapacitates an employee and could result in termination of employment.

Lost Workday Cases: Any work related injury other than a fatal injury which results in a person being unfit for work or unable to resume normal duties on the next day or next shift following the date of the accident or the date of diagnosis of the illness.

Note:

A medical practitioner must verify this.

Normal duties are those tasks that were required to be performed by the employee in accordance with the appointment in the organisation.

Total Number of Lost Time Injuries (LTI): this is sum of fatalities, Permanent Total Disabilities and Lost Work Day Cases.

Man days Lost due to Injuries (New): The number of days a person is unfit for work because of an Occupational Accident / Illness. New if in the period under consideration.

Man days Lost due to Injuries (Ongoing): The number of days a person is unfit for work because of an Occupational Accident / Illness. Ongoing if it happened earlier and the days of absence is carried over to the current period under consideration.

Restricted Workday Cases (RWDC): Any occupational injury or illness other than a fatality or lost work day case which results in a person being unfit for full performance of the regular job on any day after the occupational injury.  Work performed might be:

an assignment to a temporary job;

part-time work at the regular job;

continuation full-time in the regular job but not performing all the usual duties of the job.

Where no meaningful restricted work is being performed, the incident is recorded as a lost workday case (LWDC).

Number of days of Restricted Work: it is the total number of days the injured person is put on restricted work.

Medical treatment cases (MTC) for treatment of injury: Any work related injuries that are not severe enough to be reported as fatalities or lost work day cases or restricted work day cases, but are more severe than requiring simple first aid treatment.  A MTC requires treatment by a medical professional (which includes medics and nurses) e.g. stitching of cuts, application of special bandages, removal of foreign bodies (from eyes, skin/flesh).

First aid Injuries: occupational injuries that can be successfully treated by a qualified first-aider and does not require further treatment by a medical professional.

Occupational Illness: An Occupational Illness is an Incident.  Occupational illness is any work related abnormal condition or disorder, other than an occupational injury (which is occupational safety – see below), caused by, or mainly caused at work.

Identification of occupational illness should be made by a physician or any other person who, by virtue of training or experience, is deemed competent to do so.  In cases where it is not possible to establish unequivocally whether an illness is occupational or not, good faith determination should be applied, even if this means over reporting of cases, which is acceptable.

Back problems and lower limb disorder (incl. ergonomic related disorders) e.g. synovitis, tenosynovitis and bursitis; Raynaud’s Phenomenon; other disorders of the musculo-skeletal system and connective tissue associated with repeated trauma.

Upper limb and neck disorder (incl. ergonomic related disorders) e.g. synovitis, tenosynovitis and bursitis; Raynaud’s Phenomenon; other musculo-skeletal and connective tissue disorders associated with repeated trauma.

Cancer and malignant blood disease e.g. mesothelioma; bladder cancer; leukaemia and other malignant diseases of blood  and blood forming organs caused by exposure to carcinogenic substances

Infections/preventable disease e.g. malaria, food poisoning, infectious hepatitis, dysentery, legionnaires disease

Mental ill-health e.g. tension headache, depression, neurosis, stress, functional disorders of the gastrointestinal tract.

Noise induced hearing loss e.g. hearing threshold at 4000Hz of 40 dB or more, averaged for both ears.

Poisoning e.g. poisoning by lead, mercury, arsenic, cadmium, or other metals; poisoning by carbon monoxide, hydrogen sulphide or other gases; poisoning by solvents; poisoning by pesticides; poisoning by other chemicals such as formaldehyde, plastics and resins.

Respiratory disease e.g. silicosis, asbestosis, pneumoconiosis, pneumonitis, allergic bronchitis, alveolitis, asthma, pharyngitis, rhinitis or acute congestion due to chemicals, dust, gases or fumes.

Skin disease e.g. contact dermatitis, allergic dermatitis, rash caused by primary irritants, sensitises or poisonous plants, oil acne, chrome ulcers, chemical burns or inflammations

Other occupational illness e.g. benign tumors, eye conditions, other non - malignant diseases of the blood or blood forming organs, heatstroke, sunstroke, heat exhaustion, and other effects of heat stress; effects of exposure to low temperature (freezing/frostbite); effects of ionising (isotopes, X-Rays, radium) and non-ionising radiation (welding flash, ultraviolet ray, microwaves, sunburn).

Near Miss Accidents: An event or chain of events that could have resulted in fatality, injury, illness and / or damage (loss) to assets, the environment, company reputation or third parties.

Dangerous Occurrence: a readily identifiable undesirable event as defined under national laws and regulations, with potential to cause an injury or disease to persons at work or the public.

Property Damage Cases: An event or chain of events that inflicted physical harm upon any asset.

Fire Incident: Any incident that is caused by fire, that may or may not have caused injury, damage (loss) to assets, the environment, company reputation or third parties.

Vehicle Incidents: Incidents involving motorised vehicles designed for transporting people and goods over land, e.g. cars, buses, trucks.  Pedestrians struck by a vehicle are classified as vehicle incidents.  Incidents involving a mobile crane would only be vehicle incidents if the crane were being moved between locations.

Marine Incidents: Incidents involving marine vessels designed to transport people and goods over water.

Security Incidents: an incident that failed to preserve the sense of protection against invasion, loss, attack, or harm.

Environmental Incidents

Spillage: Land based spill or deliberate disposal of any hazardous material.

Discharge: Marine based spill or deliberate disposal of any hazardous material.

Nuisance: Nuisance had to be one interfering materially with the personal comfort of individuals. E.g. Smoke, fumes or gases emitted from premises, dust arising from an operation, noise emitted from premises etc…

Safety Inspections: Physical on-site verification that work is performed and equipment is maintained in accordance with existing HSSE standards and procedures.  Persons that are independent from or are part of the operations organisation (e.g. senior supervisors and managers) can conduct HSSE Inspections.

Internal HSSE Audits: Audits done internally.

External HSSE Audits: Audits done by external parties/ third party

Lost Time Injury Frequency Rate (LTIF): The lost time injury frequency measures the number of lost time injuries in the exposure period as a percentage of the workforce.  It is calculated by multiplying the number of lost time injuries (LTI) by 1,000,000 and dividing by the exposure hours worked during the period.

LTIF =   No. of Lost time Injuries x 1,000,000                                                                                                             Exposure Hours

Injury Incident Rate (IIR): This gives the injury incident rate per 100,000 employees

LTIS =   Total Number of Lost Time Injuries x 100,000                                         

            Average Number of employees during this period

Mean Duration (MD): Is the average duration a person is away from work because of an occupational accident.

                        MD =    Total Days Away From Work                                                                                                                            Total Cases Involving Days Away From Work

No. of Man-hours Worked since the last L.T.A: The total hours worked between two lost time accidents.
