Message from the Administrator At Western Area Power Administration (WAPA), we show our commitment to safety every day through the actions we take, the training we offer and the work conditions we provide. We expect the same commitment to safety from each of our contractors who provide products or services to WAPA. In performing work for WAPA, all contractors must make the right decisions to ensure that the work environment is as safe as possible.

Our safety program is based on four points:

· Safety procedures or common sense must be applied by each Federal and contract employee. Safety should not be set aside to meet a project schedule or for personal convenience.

· Employees and contractors must believe that they have the right and the responsibility to identify and take action to reduce, if not eliminate, hazardous work environments and hazardous work practices.

· Managers and supervisors must lead by example and execute their responsibility to ensure each job is accomplished in a safe and healthy way.

· Safety is a personal responsibility. Each individual makes the decision on what action to take to accomplish a task.

By integrating these principles into every task we take, together we can ensure WAPA is a safe place to work.
