Infectious diseases can be viral, bacterial, parasitic or fungal infections. There's also a rare group of infectious diseases known as transmissible spongiform encephalopathies (TSEs).

an infectious disease worksite.
2. Describe the key elements of an infectious disease
occupational exposure control plan.
3. Explain the importance of workplace control methods,
including substitution, engineering controls,

Standard Precautions
25. Chapter 2: Hazard Recognition and Controls 25
• What PPE is required for the hazardous substances that may be encountered
today on the worksite?
• Which potential explosive and/or flammable conditions are present?
• Are there confined spaces present and will they be entered?
• What emergency equipment is available, where it is located, and how is it used?
• What are the standard operating procedures (SOPs) for evacuation and rescue
in an emergency?
• How will we be notified if conditions or situations change during the work shift?
• What is the work/rest cycle for each task?
• What are the prescribed decontamination procedures?
• How will the “buddy system” be enforced and how will we be paired up?
• Do I have the proper training and equipment to perform my duties?
• Are there changes in safety procedures for my task?
