Within the Utilities sector, new hazards, yet uncharacterized, may emerge as the nation strives to relieve our dependence on foreign oil and identify new sources of energy.  The increasing manufacture and operation of wind generators and increasing development of nuclear power reactors, for example, may bring unique occupational safety and health concerns to this industry, particularly among workers in the Utilities sector.  However, we do know that efforts for emergency preparedness and response involve workers in the Utilities sector.  For example, in the case of many man-made and natural disasters, utilities workers must be available and responsive following the disasters to maintain critical infrastructure. This may entail long working hours and unsafe conditions.
