Hazard assessment, electrostatic

Here, C0bject is the capacitance and V the voltage between the two metal conductors. The capacitance of typical chargeable components depends on their size, shape, and distance from a grounded surface. For purposes of electrostatic hazard assessment, it is usually convenient to rely upon measured data like that in Table 6. 

Total charge, volumetric charge density, and charge-to-mass ratio (specific charge) are useful parameters in assessing electrostatic hazards. Charge on... 

Any compd or mixt whose heat of formation is smaller by 500 J/g (or more) than the sum of the heats of formation of its reaction products must be regarded with suspicion and handled with more than usual care. The hazards involved in working with a potentially expl system are directly proportional to the amount and to the rate of energy release. Because the reaction kinetics cannot be predicted, the propensity of a new system for expl reaction must be determined. The sensitivity of the system can be evaluated by means of impact, friction, shock and electrostatic discharge. Appropriate methods are reviewed in the Experimental and Hazard Assessment section of this article. Sensitivity to heat or elevated temp may be evaluated by use of differential thermal analysis (DTA)...

In previous studies we found that improved emission-control devices (such as hot-side electrostatic precipitaters and wet-scrubber systems) now being installed on modern pulverized-coal-fired power plants modify the quantity, chemical composition, and distribution characteristics of fine aerosol emissions (12,13). Such modifications must be understood to adequately assess human health and environmental hazards, and to apportion the contributions of sources to urban pollutant inventories.
