Foundries can use a systematic approach to address worker exposures to a potential exposure hazard
such as respirable silica.
The researchers also detected THC on surfaces in 70% of the grow sites studied, but they concluded the concentrations were not high enough to present a significant exposure hazard
. These results did demonstrate, however, that surface sampling for THC can be a useful tool for environmental investigators to help document that a building has been used to grow marijuana.
Use of such a framework enables estimation of the degree of human-to-human transmission from symptom onset data and of exposure hazard
from markets; the accuracy of these estimates is greatly improved when the timing of a sudden change in hazard, such as a market closure, is known (9).
We show in Appendix A that the proof not only relies on the assumption, following , that for any subject the type-specific exposure hazard
is that of a history-independent (zero-order) process, but also that it relies on the stronger assumption that the "exposure pseudohazards" are proportional.
Figure 4 shows the computed retinal exposure hazard
level in units of microwatts at the retina as ranges for the conditions listed in Figure 3.
Risk assessments of CFL and fluorescent bulb breaks have shown that there is actually a very small exposure hazard
. Nonetheless, a proper cleanup of the area affected is a good idea.
This includes the ability and authority to stop work when the exposure hazard
The starting point for an indoor air management program should be the undertaking of an exposure hazard
assessment that is plant-wide.
The Chicago episode not only revealed a previously unidentified environmental exposure hazard
but also provided valuable lessons on how to respond quickly and efficiently.
Just as the risk manager needs to identify and treat the ethical exposure hazard
within his or her organization, the ethical standards of the organization's vendors deserve equal consideration Among insurance companies, brokers, agents, TPAs, surveillance firms, subrogation vendors, attorneys and public accounting firms, only one needs to behave unethically to impose a serious hazard on its client company.
The investigators concluded that it probably would not represent an exposure hazard
for children or risk to the environment (Birkholz et al.
