In this instrument:
                                      8-hour time-weighted average means the averaging of different exposure levels to benzene during an average exposure period equivalent to eight hours.
                                     being obese means having a Body Mass Index (BMI) of 30 or greater.
BMI = W/H2 where:
(a)          W is the person's weight in kilograms; and
(b)          H is the person's height in metres.
                                     being exposed to benzene means:
(a)          having cutaneous contact with liquids containing benzene greater than 1% by volume;
(b)          ingesting liquids containing benzene greater than 1% by volume; or
(c)          inhaling benzene vapour where such exposure occurs at an ambient 8-hour time-weighted average benzene concentration exceeding five parts per million.
Note: 8-hour time-weighted average is defined in the Schedule 1 - Dictionary.
                                     cumulative equivalent dose means the total dose of ionising radiation received by the particular organ or tissue. The formula used to calculate the cumulative equivalent dose allows doses from multiple types of ionising radiation to be combined, by accounting for their differing biological effect.
                                     The unit of equivalent dose is the sievert. For the purposes of this Statement of Principles, the calculation of cumulative equivalent dose excludes doses received from normal background radiation, but includes therapeutic radiation, diagnostic radiation, cosmic radiation at high altitude, radiation from occupation-related sources and radiation from nuclear explosions or accidents.
                                     MRCA means the Military Rehabilitation and Compensation Act 2004.
                                     myelodysplastic neoplasm (syndrome)—see subsection 7(2).
                                     one pack-year means the amount of tobacco consumed in smoking 20 cigarettes per day for a period of 1 year, or an equivalent amount of tobacco products.
Note 1: An equivalent amount of tobacco products is 7,300 grams of smoking tobacco by weight, either in cigarettes, pipe tobacco or cigars, or a combination of same. For pipe tobacco, cigars or combinations of multiple tobacco types, 1 gram of tobacco is considered to be equal to one cigarette.
Note 2: Pack-years are calculated by dividing the number of cigarettes smoked per day by 20 and multiplying this number by the number of years the person has smoked. For example, smoking 10 cigarettes per day for 10 years is equal to 5 pack-years, and smoking 40 cigarettes per day for 10 years is equal to 20 pack-years.
                                     ppm-years means parts per million multiplied by years of exposure.
                                     relevant service means:
         (a)          operational service under the VEA;
         (b)          peacekeeping service under the VEA;
         (c)          hazardous service under the VEA;
         (d)          British nuclear test defence service under the VEA;
         (e)          warlike service under the MRCA; or
         (f)           non-warlike service under the MRCA.
Note: MRCA and VEA are defined in the Schedule 1 - Dictionary.
                                     terminal event means the proximate or ultimate cause of death and includes the following:
         (a)           pneumonia;
         (b)           respiratory failure;
