Final answer:
The Occupational Safety and Health Administration (OSHA) is responsible for providing rules and regulations for fireline contractors to ensure workers are protected from various hazards, including those specific to fireline activities.
Step-by-step explanation:
The entity responsible for providing rules and regulations that would apply to fireline contractors is the Occupational Safety and Health Administration (OSHA). OSHA has the authority to issue standards to protect workers from various hazards, including fire-related risks. Therefore, the correct answer to the question is (c) OSHA. OSHA's standards encompass a wide range of protective measures for employees, such as the requirement of fall protection and the prevention of exposure to harmful chemicals. Moreover, compliance with the General Duty Clause of the OSH Act is obligatory for employers to maintain a safe work environment even when no specific OSHA standard applies to a hazard.
OSHA's role extends to the enforcement of these standards through inspections and assessments of penalties for non-compliance. Regulations might include guidelines on hazardous chemical exposure, the use of personal protective equipment, and the prevention of falls and operating dangerous equipment, ensuring comprehensive safety measures are in place for fireline contractors.
