When making the assessment, the employer or self-employed person must keep a record of the assessment
and take into account such matters as-
(a) the HCA to which an employee may be exposed;
(b) the effects the HCA may have on an employee;
(c) where the HCA may be present, and the physical form in which it is likely to exist;
(d) the route of intake by which, and the extent to which, an employee may be exposed; and
(e) the nature of the work process, and any reasonable deterioration in, or failure of, control measures.
