The toxicity and the physiological action of insecticides, fungicides, rodenticides, and herbicides on plants are of basic importance. The toxicity of treated plants to animals, and the toxicity of treated plants and animals to humans and to wildlife are of practical concern. A long-range consideration of the effect of sprays on both plant and human nutrition and its relation to public health is of direct concern. The hazards in field application and methods of protecting operators should be reported in detail and further research should be emphasized. 

INDUSTRIAL SAFETY PROVISIONS. In the design of the APE and associated operational shield, conventional machine design practices are used to protect operators from hazards associated with moving parts. Proper techniques for guarding of hazardous machine areas are used, including the use of interlocks In the control system to prevent movements until certain conditions are satisfied, or to stop movements In emergency situations... 

Assessment endpoint An explicit expression of the enviromnental value that is to be protected, operationally defined by an ecological entity and its attributes. For example, sahnon are valued ecological entities reproduction and age-class structure are some of their important attributes. Together salmon reproduction and age-class structure form assessment endpoints.

Electrical safety. Most common commercial instruments have been certified for electrical safety by an organization such as UL (Underwriters Laboratory), CE, or CSA (Canadian Standards Association). However, certain less common instruments or custom-built instruments may have to go through a certification process at the time of installation. Certification required for electrical safety may take time to complete. A protective shield or casing may be required for automated systems with robotic arms for sample manipulation, to protect operators. 

The first step has already been mentioned in this chapter. Step 2 is a combined reduction/protection operation. 

Operative personnel must understand that the containment and barrier techniques used in the operation of the BSC are significant not only as protection against sudden, overt contamination, but more importantly, as barriers to traces of residual contamination to which constant exposure may present long term health risks. Current pharmacy practices and contamination control manipulative techniques have been shown to be inadequate to contain hazardous substances in all phases of compounding and administration, and a pharmacy-wide study and standardized, remedial training programs must by quickly developed and carried out to protect operative personnel. ... 

HS-SPME conditions for analysis of TFSV (temperature, sampling time, pH of solution) were reported by Fedrizzi et al., (2007b). Increase of the pH matrix at a value of 7, performed in order to reduce interference in the analysis due to presence of hexanoic acid, can reduce the 3-mercaptohexyl acetate hydrolysis. Unfortunately, the antioxidant protection operated from S02 is also reduced (due to the shift of equilibrium towards the HSOj form) as a consequence phenolic acids can be easily oxidized forming the correspondent quinones (Singleton, 1987 Murat et al., 2003). They can, in their turn, oxidize thiols (Rigaud et al., 1991), even if with an opportunely delayed time as evidenced by Blancard et al. 

Many solvents commonly used in academia are rarely used for scale-up in industry. A list of such solvents is shown in Table 4.2, along with the disadvantages of these solvents and alternative solvent choices. While any solvent can be used on scale, one must compare the advantages of using an undesirable solvent to the inconvenience, additional costs, and extended process times required to protect operators and equipment. All of these considerations reduce productivity and drive up processing costs on scale. 

Protect operators, analysts, plant facilities, and communities. 

Most reactions in scale-up facilities are conducted at or slightly above atmospheric pressure. Reactors are generally fitted with rupture disks set to release at about 25 psi. This allows a reactor to be sealed and contain toxic or irritating components, thus protecting operators and maintaining suitable levels of volatile reagents... 

The first step in developing accurate IPCs is to obtain a representative sample of the reaction, one that accurately reflects the extent of reaction and the profile of impurities in the reactor at the time the sample was withdrawn. Two sets of parameters must be considered whether the reaction is homogeneous or heterogeneous, and the temperature of the reaction relative to the temperature of the sample preparation. All samples must be taken safely, with precautions where appropriate to protect operators and to exclude atmospheric moisture and 02 from both the reactor and the sample. 

In many operating instructions referring to light-sensitive samples, the precautions that have to be taken are mentioned either simply in the form of footnotes or not at all. However, especially in these circumstances it is essential that the necessary advice on light-protected operation should be given clearly and emphatically at the start of the testing procedure. This is also the case if relatively insensitive substances in sohd form decompose rapidly when in solution.

The exposure potential from adjacent facilities due to catastrophic incidents such as a fire, explosion, or a chemical release should be identified when conducting a site assessment. Reassessments of nearby facilities may also be warranted as changes to the surrounding exposures occur over time. High hazard or poorly protected operations may present a risk to a nearby chemical warehouse. The most effective approach for minimizing the exposure is usually sufficient spatial separation or fire walls. Locating a chemical warehouse adjacent to airports, highways and railroad lines may also result in an exposure, albeit remote.
