Inhalation exposure waivers

In cases where solids are being proposed as candidates for inhalation exposure waivers, it will be further required that the solid be proven to be non-friable, as defined by the American Society for Testing and Materials (ASTM). 

Most regulatory jurisdictions will consider a science-based rationale to waive an occupational or residential exposure data requirement. For example, under NAFTA, the USEPA and Health Canada s PMRA have agreed upon guidance for considering a waiver for inhalation exposure data. Considerations are based on volatility, engineering considerations and particle size, and are outlined in Table 10.1. 

Products handled using specific engineering controls that mitigate inhalation exposure. Examples of engineering controls which may allow a product to be a candidate for a waiver include formulations used in closed systems for the entire mix/load/application...
