To improve oil-spill prevention, Exxon has:

	Modified tanker routes.
	Applied new technology to improve vessel navigation and ensure the integrity of oil containment systems.
	Instituted drug and alcohol testing programs for employees and contractors in safety-sensitive positions.
	Restricted safety-sensitive positions to employees with no history of substance abuse.
	Conducted more extensive, periodic assessments of Exxon vessels and facilities.
	Strengthened training programs for vessel captains and pilots.
	The Valdez accident further prompted Exxon to conduct a thorough reexamination of safety programs in all operations, covering accidents of every kind. One major outgrowth of this worldwide initiative is Exxon's Operations Integrity Management System (OIMS). OIMS sets specific safety, health, incident prevention and environmental expectations against which all Exxon operations are regularly assessed. In addition to reducing risks and incidents, OIMS ensures a disciplined approach to emergency response.

Exxon improved its response capability by:

	Co-founding major oil-spill response centers throughout the world.
	Developing and applying new spill-detecting technology.
	Creating the most effective, environmentally safe oil-spill dispersant, Corexit 9500.
	Conducting frequent and extensive oil spill drills at various company locations.
	Assigning more than 1,000 employees to oil-spill response teams.
