SCHEDULE 4B – Pneumoconiosis score

1 Definitions for schedule

In this schedule—

"category" see section 2 (1) (b) .

"consecutive categories" see section 3 .

"corresponding score" , for a category, means the score in section 2 (1) , table 1, column 2 that corresponds to the category.

"reading" , of a chest x-ray, see section 2 .

2 Meaning of reading of chest x-ray

(1) A
"reading" , of a chest x-ray, is a process in which a qualified reader—
(a) assesses the x-ray for the appearance of opacities; and
(b) decides, in accordance with the ILO classification guidelines, the category in table 1, column 1 (the
"category" ) that applies to the appearance of opacities in the x-ray; and
(c) records the category decided under paragraph (b) .

(a) a small opacity within the meaning of the ILO classification guidelines; or
(b) a large opacity within the meaning of the ILO classification guidelines.

"qualified reader" means a doctor who is qualified and competent to categorise, in accordance with the ILO classification guidelines, the appearance of opacities in a chest x-ray.
Example—
a doctor approved as a B Reader by the National Institute for Occupational Safety and Health

3 Meaning of consecutive categories

Two categories are
"consecutive categories" if the categories—

(a) start with the same digit, other than 0; and
(b) appear in consecutive rows in section 2 (1) , table 1.
Examples of categories that are consecutive categories—
• 2/1 and 2/2
• 3/3 and 3/+
Examples of categories that are not consecutive categories—
• 0/0 and 0/1
• 1/2 and 2/1
• category B and category C

4 Requirement for 2 readings

(1) A worker’s pneumoconiosis score is worked out by using 2 readings of the same chest x-ray of the worker in the way provided under subsection (2) or (3) .
(2) If each reading records the same category, the worker’s pneumoconiosis score is the corresponding score for that category.
(3) If each reading records a different category, the worker’s pneumoconiosis score is—
(a) if the 2 categories are any combination of 0/-, 0/0 or 0/1—0; or
(b) if the 2 categories are consecutive categories—the higher of the corresponding scores for the consecutive categories; or
Example for paragraph (b)—
One reading records the category as 2/2, which has a corresponding score of 55. The other reading records the category as 2/3, which has a corresponding score of 60. The worker’s pneumoconiosis score is 60, being the higher of the corresponding scores for the consecutive categories.
(c) if the 2 categories are any combination of category A, category B or category C—the higher of the corresponding scores for the 2 categories.
Example for paragraph (c)—
One reading records the category as category A, which has a corresponding score of 90. The other reading records the category as category C, which has a corresponding score of 100. The worker’s pneumoconiosis score is 100, being the higher of the corresponding scores for the 2 categories.

5 Requirement for third reading

(1) This section applies if the worker’s pneumoconiosis score can not be worked out under section 4 .
(2) The worker’s pneumoconiosis score is worked out by—
(a) obtaining a third reading of the same chest x-ray; and
(b) using that reading, with the first 2 readings, in the way provided under subsection (3) or (4) .
(3) If the third reading records the same category as either of the first 2 readings, the worker’s pneumoconiosis score is the corresponding score for that category.
(4) If the third reading records a different category from both of the first 2 readings, the worker’s pneumoconiosis score is—
(a) if 2 of the 3 categories are consecutive categories—the higher of the corresponding scores for the consecutive categories; or
Example for paragraph (a)—
The first 2 readings record the categories as 1/2 and 2/1. The third reading records the category as 2/2. Because the categories of 2/1 and 2/2 are consecutive categories, the worker’s pneumoconiosis score is 55, being the higher of the corresponding scores for the consecutive categories.
(b) if 2 of the 3 categories are any combination of category A, category B or category C—the higher of the corresponding scores for the 2 categories.
Example for paragraph (b)—
The first 2 readings record the categories as 3/+ and category A. The third reading records the category as category B. The worker’s pneumoconiosis score is 95, being the higher of the corresponding scores for category A and category B.

6 Requirement for fourth and fifth readings

(1) This section applies if the worker’s pneumoconiosis score can not be worked out under section 4 or 5 .
(2) The worker’s pneumoconiosis score is worked out by—
(a) obtaining a fourth and fifth reading of the same chest x-ray; and
(b) using those readings, with the other 3 readings, in the way provided under subsection (3) .
(3) The worker’s pneumoconiosis score is the corresponding score for the median category of the categories recorded in each of the 5 readings.
Example—
The first 3 readings record the categories as 1/2, 2/1 and 2/3. The fourth and fifth readings record the categories as 1/2 and 2/1. The 5 categories, in ascending order, are 1/2, 1/2, 2/1, 2/1 and 2/3. The median category is 2/1, and the worker’s pneumoconiosis score is 50.
