Centers for Disease Control(CDC)

Material Safety Data Sheet(MSDS)
A document containing information and instructions on hazardous materials present in the workplace. It contains details about hazards and risks relevant to the substance, requirements for its proper handling, and actions to be taken in the event of fire, spill, or overexposure.
National Institute for Occupational Safety and Health (NIOSH)
Conducts research and makes recommendations for the prevention of work related disease and injury. The institute is a part of the CDC.
Occupational Safety and Health Administration (OSHA)
A branch of the US Department of Labor responsible for establishing and enforcing safety and health standards in the workplace.
The condition of possessing freedom from being exposed to risk, danger, or harm.
A simple model for understanding the ingredients necessary for most fires. The model illustrates the required three elements: heat, fuel, and an oxidizing agent (usually oxygen).
The correct relationship or position of the head, back, and limbs.
Positions and movements used to maintain proper posture and avoid muscle and bone injuries.
Bacteria which require oxygen in order to grow and survive.
an infectious disease caused by the human immunodeficiency virus (HIV).
Bacteria that do not require oxygen.
Solutions that are applied to the directly to the skin to prevent or slow growth of pathogens.
The process of killing pathogenic organisms or rendering them inert.
Potentially serious form of liver inflammation due to infection by virus (HBV). It occurs in both rapidly developing (acute) and long-lasting (chronic) forms, and is one of the most common chronic infectious diseases worldwide.
The science that studies living organisms and their effects on other living organisms, which cannot be seen by the naked eye.
The complete elimination or destruction of all living microorganisms.
Potentially fatal contagious disease that can affect almost any part of the body but is mainly an infection of the lungs. It is caused by a bacterial microorganism, the tubercle bacillus
Chain of Infection
Process that begins when an agent leaves its reservoir or host through a portal of exit, and is conveyed by some mode of transmission, then enters through an appropriate portal of entry to infect a susceptible host.
Capable of being transmitted from one individual to another; communicable.
An inanimate object or substance, such as clothing, furniture, or soap, that is capable of transmitting infectious organisms from one individual to another.
An organism that harbors or nourishes another organism (the parasite)
Lack of susceptibility to certain pathogens.
The disinfecting of materials to prevent disease
Mode of transmission
By which a communication, document, or record travels from its originator to the intended audience or receiver.
An infection that can be acquired in a hospital
Portal of Entry
The area in which a microorganism infultrates the body. They may be cuts, lesions, injection sites, or natural body orifices.
Portal of Exit
A place that provides a way for the microorganism to leave
An alternate host or passive carrier of a pathogenic organism.
Techniques used to destroy all pathogenic organisms before they can enter the body
High-Efficiency Particulate Air (HEPA) filter
Satisfies certain standards of efficiency such as those set by the United States Department of Energy (DOE). Must remove 99.97% of all particles greater than 0.3 micrometer from the air that passes through.
Personal Protective Equipment (PPE)
Equipment designed to prevent the wearer's from injury by blunt impacts, electrical hazards, heat, chemicals, and infection, for job-related occupational safety and health purposes, and in sports, martial arts, combat, etc.
Guidelines recommended by the Centers for Disease Control and Prevention for reducing the risk of transmission of blood-borne and other pathogens in hospitals.
A set of practices that apply to patients with documented or suspected infection or colonization with highly transmissible or epidemiologically important pathogens for which precautions beyond the standard precautions are needed to interrupt transmission in health-care settings.
