Unintended exposure

Addressing the Risks of Unintended Exposure 16.4.2.1 Controlling Transgene Expression... 

Purpose Potential for effects from unintended exposure Predict and evaluate clinical findings and preclude serious hazards from clinical use... 

The damaging aspects of nuclear radiation must always be kept in mind, especially when the possibilities of accidental or unintended exposures are great. However, the radiation from radioisotopes can be put to beneficial use. 

Sometimes you may have finished the chemical activity in a lab and simply be working on calculations, writing notes in your lab notebook. Since other students may still be working with chemicals, you must keep your goggles on while in the lab to prevent unintended exposure. 

For reasOTis of unintended exposure to medicines the syringe method is preferred, especially when it is not the patient who carries out the preparation. The disadvantage of shaking in a syringe is that it can be time-consuming. When a number of tablets have to be processed, time is often important. For aU of these methods it is best to process one solid dosage unit at the time. 

Laser safety with respect to operator, fiber breakage leading to an unintended exposure hazard with possible skin, or ocular damage the need for operator training in regular operating conditions, under process maintenance conditions and emergency shutdown procedures... 

Measures shall be taken to reduce the probability of abnormal operating situations or events that could lead to unintended exposures, and in addition to mitigate the consequences of any such situations or events should they nonetheless occur. These measures for prevention and mitigation may be identical in some cases to those providing protection during normal operations, but in other cases different or additional measures may be needed. 

Exposures to the chemical carbon monoxide (CO) can be very significant in a warehouse environment. Carbon monoxide is the by-product of the incomplete combustion of any material containing carbon such as gasoline, natural gas, oil, propane, coal, or wood. CO is a colorless, odorless, tasteless gas that can cause harm without warning. Unintended exposure to CO in the United States claims more than 800 lives each year. The Centers for Disease Control identified 11,547 CO deaths from 1979 to 1988. Some 40 percent of all CO poisonings occur at work sites, may of which are warehouses, states the National Safety Council.
