IMAP Assessments - Tranche Two

Tier I Human health assessments


The chemicals listed in Table 1 are not considered to pose an unreasonable risk to the health of workers and public health on the basis of the Tier I assessment (high throughput assessments).

The Tier I assessment take into account both potential human health hazard and the potential for exposure. As such, Table 1 includes hazardous chemicals and therefore all requirements under workplace health and safety and poisons legislation as adopted by the relevant state or territory should be met to minimise risk. Chemicals which have been identified as not being introduced into Australia for industrial uses are assessed as posing no unreasonable risk regardless of hazard. This includes chemicals for which existing controls preclude industrial use in Australia or chemicals for which no Australian use, import, or manufacture was reported under previous NICNAS mandatory calls for information.

Table 1  (which is the Tier I assessment output) contains the key information used in the Tier I assessment to determine the potential for exposure (exposure band), including the highest use category that has been considered. More information on exposure bands and use categories is provided in the Inventory Multi-tiered Assessment and Prioritisation (IMAP) Framework document.

Tier II Human Health Assessments


The chemicals listed in Table 2 have been assessed at Tier II (individual chemical evaluation) because the Tier I assessment indicated that it needed further investigation. The Tier II assessment report for each chemical can be accessed by clicking on the hyperlink (Chemical CAS Registry Number) in the table.


Tier I Environment Assessments


The chemicals listed in Table 3 are not considered to pose an unreasonable risk to the environment on the basis of the Tier I assessment (high throughput assessments). More information on the polymer assessment methodology used is provided in Attachment B of the Inventory Multi-tiered Assessment and Prioritisation (IMAP) Framework document.
