They should prevent or, where this is not reasonably practicable, adequately control exposure to the hazards by using and maintaining suitable controls.
Ideally, these comparisons would also have been conducted in vivo, but because of the time and expense involved in conducting such in vivo exposures, it was not practicable to do so.
Moreover, they are not practicable in a general practice setting due to their extensiveness.
Practicable means easily put into practice and does not mean practical.
Where this is not practical, the next level of controls should limit the number of workers exposed and reduce the intensity and duration of the exposure to as low as reasonably practicable.
The requirement for an upgrade of the diagnostics for the JET ITER Like Wall (ILW) while maintaining personnel exposure to contamination as low as reasonably practicable or ALARP, has necessitated the development of a bespoke set of diagnostic components.
To ensure reliable and reproducible responses to challenges, future studies in which subjects are evaluated in an environmental medical unit, a hospital-based facility in which background chemical exposures are reduced to the lowest levels practicable, may be necessary.
The choice of the control measures depends on the actual exposure circumstance, the workplace and practicality, but the objective is to eliminate the harmful exposure or control the level of exposure as low as reasonably practicable.
In its own quarterly report, British bank Barclays noted possible litigation over $76 billion in bonds issued during the boom, but declined to estimate how much the damage would be in court, saying, "It is not practicable to provide an estimate of the financial impact of the potential exposure".
We believe that the size, chemistry, and solubility can affect the toxicological outcome from particle exposure and agree that these features should be reported wherever practicable.
