Biohazard - Use Universal Precautions Sign
Use universal precautions whenever there is a potential for exposure to bloodborne pathogens.

Exposure Control Methods

Methods To Control The Risk Of Exposure

The recommended infection-control concept called "Universal Precautions" advocates everyone's blood and body fluids be considered potentially infectious. This eliminates the difficulty in determining risk individually. Remember, although some bodily fluids have not been documented to transmit pathogens, it is sometimes impossible to tell if blood or another potentially infectious fluid is present.

1. What is the basic assumption of "Universal Precautions?"

a. Only engineering controls can eliminate exposure to all infectious materials
b. Everyone should be considered infected with bacterial or viral pathogens
c. Everyone's blood and body fluids are considered infectious
d. It is universally accepted that blood as contagious

Methods To Control The Risk Of Exposure (Continued)

The two essential control strategies employees use to eliminate or minimize the transmission of bloodborne diseases in the workplace are:

  1. engineering controls
  2. work practice controls

Engineering Controls

Engineering controls minimize exposure in the workplace either by removing or isolating the hazard, such as providing a sharps container for needles, splash guards, and mechanical pipetting devices.

Engineering controls are all about the design of the equipment used to eliminate or minimize exposure.

The Sharps container for needles is a good example of an engineering control.

Employers need to examine and maintain or replace engineering controls on a regularly scheduled basis.

2. Engineering controls are all about the _____ used to minimize exposure.

a. employee practices
b. design of equipment
c. techniques
d. personal protective equipment

Work Practice Controls

Work practice controls focus on the way tasks are performed. For example, using disposable gloves when performing emergency care is considered a work practice control. Another example of work practice controls is to perform all actions involving potentially infectious material in such a way as to minimize splattering, splashing, and spraying. Proper handling and disposal of needles or sharps, contaminated bandages, gauze, or linens is also essential.

Work practice controls are all about how tasks are performed to minimize exposure.

Safe work practices include eliminating eating, drinking, smoking, applying make-up or lip balm, or handling contact lenses in locations with potentially infectious material. In healthcare facilities, employees are prohibited from wearing artificial nails. Food and drink must not be kept in a refrigerator, freezer, shelf, or in the general area of where blood or other potentially infectious material are kept.

3. Work practice controls are all about _____ to minimize exposure.

a. how tasks are performed
b. how equipment is designed
c. the use of personal protective equipment
d. written safety policies

Washing hands
After any exposure, you should wash your hands to reduce your risk of infection.

Wash your hands!

Hand washing after an exposure can reduce your risk of infection.

Your employer must provide readily accessible hand-washing facilities or antiseptic hand cleanser or wipes if hand-washing facilities are not available.

Perform hand washing immediately after any exposure, even if you were wearing gloves. Vigorous scrubbing with soap or alcohol-based foam or gel and warm water is considered the most effective technique. This will further reduce your risk of infection resulting from an exposure.

Prohibited Practices

Practices that are completely prohibited in the workplace include: bending, recapping, and removing contaminated needles, shearing or breaking needles, and mouth pipetting or suctioning of potentially infectious material.

These practices significantly increase the risk of exposure. As a result, they should never be performed by employees.

4. What can greatly reduce the risk of infection after exposure to bloodborne pathogens?

a. Wiping down surfaces
b. Latex gloves
c. Recapping used needles
d. Hand washing

Antiseptic hand cleaner in conjunction with clean cloth/paper towels or antiseptic towelettes are examples of acceptable alternatives to running water.

However, when these types of alternatives are used, employees must wash their hands (or other affected areas) with soap and running water as soon as feasible.

This alternative would only be acceptable at worksites where soap and running water are not feasible.

5. What is important to remember if you have used antiseptic hand cleaner to clean your hands?

a. Be sure to wipe your hands with a paper towel
b. Do not eat food for at least 15 minutes
c. Rinse with plain water
d. Use soap and water as soon as possible

Dr. Kramer owns and operates a small dental clinic in San Francisco, CA. As part of her exposure control plan, she requires her employees to wash their hands before and after working with any patients. She also requires new gloves be used with every patient.

Is this an example of engineering controls or work practice controls?

Work practice controls.

Dr. Kramer is requiring her employees to do something to reduce the risk of occupational exposure. Work practice controls focus on the actions taken to minimize exposure.
