Physical devices, such as needle resheathing holders and sharps containers, that help to remove biohazardous material from the workplace.
Methods of controlling worker exposures to hazardous agents by adjusting the source or reducing the amount released in the workplace. Examples include a change in process, substitution of less harmful job activities or materials, isolation, and ventilation. Engineering controls are the preferred method for targeting worksite hazards.
Method of managing environmental and health risks by placing a barrier between the contamination and the rest of the site, thus limiting exposure pathways.
Physical mechanisms for preventing exposure to contamination. Examples include: fences, pavement, and clay caps placed on contaminated soil.
Methods put in place (engineered) to control the source of worker exposure, e.g., exhaust ventilation systems or glove-box enclosures.
Systems too reduce potential hazards by isolating the worker from the hazard or by removing the hazard from the workplace. Methods include substitution, ventilation, isolation, and enclosure.
engineering systems used to prevent the transmission of TB in health care facilities, including ventilation, high-efficiency particulate air (HEPA) filtration, and ultraviolet germicidal irradiation
Physical changes to work stations, equipment, materials, production facilities, or any other relevant aspect of the work environment that reduce or prevent exposure to risk factors.
remedial actions directed toward containing or controlling the migration of contaminants through the environment. These include, but are not limited to, stormwater conveyance systems, pump and treat systems, slurry walls, liner systems, caps, leachate collection systems and groundwater recovery systems.

Means controls that isolate or remove the bloodborne pathogens hazard from the workplace. Examples include needleless devices, shielded needle devices, blunt needles, and plastic capillary tubes, (OSHA CPL 2-2.44D).
Methods of controlling employee exposures by modifying the source or reducing the quantity of contaminants released into the workroom environment.
Use of components and systems to reduce airborne radioactivity and the spread of contamination by using piping, containments, ventilation, filtration or shielding.
means controls (e.g., sharps disposal containers, self-sheathing needles, safer medical devices, such as sharps with engineered sharps injury protections and needleless systems) that isolate or remove the bloodborne pathogens hazard from the workplace.
Common control measures including isolation, enclosure and ventilation
A method of controlling worker exposure to risk factors by redesigning equipment, tools, and work stations. Engineering controls are part o hazard prevention and control.
The 2002 Infection Control Guidelines released by Health Canada state that:"Engineering Controls decrease healthcare workers (HCWs) exposure to a hazard by reducing the hazard at the source, e.g. design modifications for sharp instruments making them safer and less likely to pierce the skin of HCWs, potentially exposing them to bloodborne pathogens." It further states that:"Early attempts to control exposures to blood and bodily fluids focused on the use of safety guidelines and education. However, evidence indicated that this did not lead to fewer needlestick injuries. Engineering controls were recommended as a more effective way to control healthcare worker exposures…"
physical changes to a job that reduce musculoskeletal disorders. Examples of engineering controls include changing or redesigning workstations, tools, equipment or processes.
