Occupant vulnerabilities are one of the key factors in determining the levels of both individual and aggregate risks for building occupants. Occupant vulnerabilities are used in risk screening as discussed in Chapter 4 and are used in detailed risk assessments.

The design requirements for intrinsically safe would seem to be demanding, and a review of NFPA 493 enforces this fact. Today s industrial environment imposes additional requirements not only on the use of intrinsically safe electrical circuits, but other hazardous electrical techniques as well. These requirements are due to the Occupational Safety and Health Act and the employer s increasing vulnerability for liability. 

Industrial workers make up the segment of the population that is most vulnerable to chemical injury. To protect them from occupation-related harm, the American Conference of Governmental and Indnstrial Hygienists publishes annually revised threshold limit values (TLVs), guidelines for permissible chemical exposure at the workplace. http //www.acgih.org/Resources/press/HAL.htm... 

The cation occupancies of todorokite may also account for the relative stability of this mineral towards oxidation. Todorokite is destabilized by the presence of substantial Mn2+ and Mn3+ ions in the structures, because these cations are vulnerable to oxidation. Thus, Mn2+-bearing todorokites show oxidation to manganite and vemadite. However, replacement of Mn2+ or Mn3+ by Mg2+, Ni2+, Zn2+ and Cu2+, which are not susceptible to oxidation, stabilizes todorokite, particularly in manganese nodule deposits. 

Coral reefs occupy a large part of the seas in the tropics of the Pacific and the Caribbean. They are the most diverse and complex marine communities, supporting thousands of fish, algae, and invertebrate species. Studies and actual spills have shown that moderate concentrations of dissolved or dispersed hydrocarbons can kill both the coral and its occupants. Damage depends on the depth, with coral that is near the surface (down to about 6 m) being particularly vulnerable to oil. Many of the animals can repopulate the area rapidly, but since the coral is their primary support, full recovery depends largely on the recovery or recolonization of the coral. Once dead, the coral itself can be very slow to recover. Oil also has several sublethal effects on coral, such as slowed growth or respiration and unnatural coloration.
