Answer to Question 2
Contractors, as the owners of the company, bear the ultimate responsibility for safety and health on their job sites. Contractors are responsible for the following: 1) setting a pro-safety tone for the company, 2) establishing a complete commitment to safety and health from the top down, and 3) ensuring that sufficient resources are provided to support a comprehensive, company-wide safety effort. By letting their managers and supervisors know that they expect safe and healthy job sites, contractors set a tone for the company which ensures that safety and health will be high priorities. By including safety and health in the company's strategic plan, contractors can establish the necessary commitment on the part of all employees. By providing the resources necessary to support company-wide safety and health programs, contractors ensure that the safety and health program is properly staffed and sufficiently funded.
