As you know, Applied Materials had a recent facilities shutdown to perform maintenance that your company participated in. During the course of that shutdown, our Corporate Environmental Health and Safety Department performed walk-through inspections of all work sites. We were pleased to observe your supervisors enforcing Applied Materials safety procedures and to see your employees working in a safe and healthy work environment.
