GOALS

BACKGROUND
 In 1988, improperly disposed medical debris washed up on
beaches in New Jersey. This spurred Congress to enact the Medical
Waste Tracking Act.
 EPA estimates that there are approximately 1 million medical waste
generators in the United States who produce 4 million tons of medical
waste each year.
 Included in those 4 million tons of medical waste produced annually
is 500,000 tons of “infectious” medical waste.
 In August 2000, several beaches in Nassau County, New York
were closed because of needles and other medical-related debris
found along the shoreline.

LEARNERS

The goal of this course is to provide supervisors
with the tools needed to properly manage medical
waste. It recommends practical, actions that can be
carried out by facility management, maintenance
personnel and building occupants. The course will
help you to integrate good medical waste
management activities into your existing
organization and identify which of your staff have
the necessary skills to carry out those activities.
OVERVIEW

WHAT THIS COURSE DOES NOT DO
The course is not intended to provide information to
operate medical waste treatment equipment. These
specialties required training beyond the intended
scope of this course. Where this expertise is
needed, outside assistance should be solicited.

MEDICAL WASTE TRACKING ACT
 Two-year demonstration program for the tracking of
medical waste. Only four states and the Commonwealth
of Puerto Rico participated in the tracking program.
 This demonstration program began June 22, 1989
and ended June 22, 1991.
 Currently the program is expired and there is no
federal tracking regulations in effect.
 Many states have developed programs based on the
federal model.

OTHER APPLICABLE
REGULATIONS
• 29 CFR 1910.1030 – OSHA’s Bloodborne Pathogen
Standard
• 49 CFR 173.196 Department of Transportation’s
Packaging of Infectious Substances for Shipment
• 49 CFR 173.197 Department of Transportation’s
Packaging of Regulated Medical Waste for Shipment.

WHAT IS A MEDICAL WASTE?
Definition of Medical Waste
In this course, medical waste
includes all infectious waste,
hazardous (including low-level
radioactive wastes), and any other
wastes that are generated from all
types of health care institutions,
including hospitals, clinics, doctor’s
(including dental and veterinary)
offices and medical laboratories.

WHAT IS A REGULATED MEDICAL
WASTE?
Definition of Regulated Medical Waste
Regulated Medical Waste is a subset of all medical
wastes and include seven distinct categories:
1. Cultures and stocks of infectious agents.
2. Human pathological wastes (e.g. tissues, body parts)
3. Human blood and blood products
4. Sharps (e.g. hypodermic needles and syringes)
5. Certain animal wastes
6. Certain isolation wastes (e.g. wastes from patients
with highly communicable diseases)
7. Unused sharps.

WHAT IS AN INFECTIOUS
WASTE?
Definition of an Infectious Waste
EPA has provided the following guidance on what
constitutes an infectious waste. These factors include:
1. Presence of a pathogen of sufficient virulence
2. Dose
3. Portal of entry
4. Resistance of host
Thus, for a waste to be infectious, it must contain a
pathogen with sufficient virulence and quantity so that
exposure to the waste by a person or animal could
result in an infectious disease.

WASTE?
EPA categorizes infectious wastes into the following
seven categories:
1. Isolation wastes – wastes generated by hospitalized
patients who are isolated to protect others from
communicable diseases.
2. Cultures and stocks of infectious agents and
associated biologicals – this category includes:
- Specimens from medical and biological laboratories
- Cultures and stocks of infectious agents from
clinical, research, and industrial laboratories
3. Human blood and blood products – this includes
waste blood, serum, plasma, and blood products.

WASTE?
4. Pathological waste – tissues, organs, body parts,
blood, and body fluids.
5. Contaminated sharps – contaminated hypodermic
needles, syringes, scalpel blades, Pasteur pipettes, and
broken glass.
6. Contaminated animal carcasses, body parts, and
animal bedding
7. Miscellaneous Contaminated Wastes – these include:
- Wastes from surgery and autopsy
- Miscellaneous laboratory wastes
- Dialysis unit wastes
- Contaminated equipment

INFECTIOUS WASTE
MANAGEMENT PLANS
Components of an Infectious Waste Management Plan:
1. Designation of the waste that should be managed as infectious
2. Segregation of infectious waste from the noninfectious waste
3. Packaging
4. Storage
5. Treatment
6. Disposal
7. Contingency measures for emergency situations
8. Staff training

DESIGNATION OF AN
INFECTIOUS WASTE
The infectious waste plan for your
facility should specify which wastes
are to be managed as infectious
wastes. The previous slides in this
course can help determine what
should be included. A responsible
official or committee should
determine any other miscellaneous
wastes should be handled as an
infectious waste.

SEGREGATING MEDICAL
WASTES
 Segregation of infectious wastes at
the point of origin.
 Segregation of infectious waste with
multiple hazards as necessary for
management and treatment.
 Use of distinctive, clearly marked
containers or plastic bags for
infectious wastes.
 Use of the universal biological
hazard symbol on infectious waste
containers as appropriate.

SEGREGATING MEDICAL
WASTES
 Whenever possible, do not combine
medical waste with hazardous chemicals
or radioactive waste.
 Separate sharps waste from other
medical wastes. Sharps should be
stored in puncture-proof containers.
 Separate pathology wastes from other
medical wastes.
 Separate chemotherapy wastes from
other medical wastes.

SEGREGATING MEDICAL
WASTES
If different types of waste are mixed, treat mixtures as
follows:
 Mixtures of medical and radioactive waste
--decontaminate the biohazardous component and
manage as radioactive waste.
 Mixtures of medical and hazardous chemical waste -- if
safe to do so, decontaminate the biohazardous
component and manage as chemical waste.
 Mixtures of medical, radioactive, and hazardous
chemical waste -- if safe to do so, decontaminate the
biohazardous component and manage as radioactive
waste.

PACKAGING INFECTIOUS WASTE
 Selection of packaging materials that are appropriate
for the type of waste handled:
- Plastic bags for many types of solid or semisolid
infectious waste.
- Bottles, flasks, or tanks for liquids.
 Use of packaging that maintains its integrity during
storage and transport,
 Closing the top of each bag by folding or tying as
appropriate for the treatment or transport
 Place liquid wastes in capped/ tightly stopped bottles.
 Do not compact infectious wastes before treatment.

HANDLING SHARPS
 Each year there are some 600,000 incidents where
people are accidentally stuck by needles and sharps.
 The most common times of risk for spreading
bloodborne pathogens occurs:
– Recapping needles
– Failing to dispose of used needles properly in puncture-
resistant sharps containers
– Accidental breakage of the tubes used for collection of blood
in a variety of health care settings. There are an estimated
2,800 injuries from these glass capillary tube breakage every
year.

HANDLING SHARPS
To protect against needlestick injuries, take the
following precautions:
 Avoid the use of needles where safe and effective
alternatives are available.
 Help your employer select and evaluate devices with
safety features that reduce the risk of needlestick injury.
 Use devices with safety features provided by your
employer.
 Avoid recapping needles.
 Plan for safe handling and disposal of needles before
using them.

HANDLING SHARPS
 Promptly dispose of used needles in
appropriate sharps disposal containers.
 Report all needlestick and sharps-related
injuries promptly to ensure that you receive
appropriate followup care.
 Tell your employer about any needlestick
hazards you observe.
 Participate in training related to infection
prevention.
 Get a hepatitis B vaccination.

PACKAGING OF SHARPS
 Containers are rigid puncture-resistant containers
that, when sealed, are leak resistant and cannot be
reopened without great difficulty.
 Must be red in color, have a biohazard label, be
accessible to employees, and be located as close as
feasible to the immediate area where sharps are used.
 Must remain upright throughout use and be replaced
routinely. Should not be overfilled to present a hazard.
 Containers of contaminated sharps will be closed
immediately.
 Secondary containers must be closable and prevent
leakage during handling, storage, transport, or shipping.

STORAGE
Storage temperature and duration are important
considerations. Warmer temperatures cause higher
rates of microbial growth and putrefaction, resulting in
odor problems. EPA recommends:
 Locating the storage area near the treatment site.
 Minimizing storage time.
 Proper packing that ensures containment of
infectious waste and the exclusion of rodents and
vermin.
 Limited access to storage areas.
 Prominently displaying the universal biological hazard
symbol on storage area door, waste containers, etc.

TRANSPORT
 Avoidance of mechanical loading devices that may
rupture packaged wastes.
 Frequent disinfection of carts used to transfer wastes
within the facility.
 Placement of all infectious waste into rigid or semi-
rigid containers before transport off site.
 Transport of infectious waste in closed leakproof
trucks or dumpsters.
 Use of appropriate hazard symbols in accordance
with local, state and federal regulations.

MEDICAL WASTE HAULING
There are three methods for
transporting regulated medical waste,
including sharps, to a permitted
regulated medical waste treatment or
storage facility.
1. By a healthcare professional
employed by the facility.
2. By contract with a transporter
registered with the state.
3. By mail, parcel post, or courier
service (sharps only).

MEDICAL WASTE HAULING
Transporting by the U.S.
Postal Service may be
arranged, provided the
addressee is a
treatment/disposal facility
permitted by a state.
 A mailed parcel of used
sharps must be mailed as First
Class or Priority Mail. No
package may weigh more than
35 pounds, and the total liquid
volume may not exceed 50 ml.

ON-SITE TREATMENT
There are several methods that have been successful in
the treatment of infectious waste. The following slides
will discuss treatment that may be available at your
facility. The methods discussed are:
1. Autoclaving (steam sterilization)
2. Incineration
3. Thermal inactivation
4. Gas/Vapor Sterilization
5. Chemical Disinfection
6. Sterilization by irradiation (radiofrequency and
microwave)

AUTOCLAVING
 Autoclaving (heating under high pressure) is widely
accepted as an effective medical waste treatment
technology.
 Steam sterilization, autoclaving, involves the use of
saturated steam within a pressure vessel at
temperatures high enough to kill infectious agents in the
waste. Sterilization is accomplished primarily by steam
penetration.
 Steam sterilization is most effective with low-density
material such as plastics, metal pans, bottles, and
flasks. High-density polyethylene and polypropylene
plastic should not be used in this process because they
do not facilitate steam penetration to the waste load.

AUTOCLAVING
 Plastic bags should be placed in a rigid container
before steam treatment to prevent spillage and drain
clogging.
 Bags should be opened and caps and stoppers
should be loosened immediately before they are place
in the steam sterilizer.
 Care should be taken to separate infectious wastes
from other hazardous wastes.
 Infectious waste that contains noninfectious hazards
should not be steam-sterilized.
 Waste that contains antineoplastic drugs, toxic
chemicals, or chemicals that would be volatilized by
steam should not be steam-sterilized.

AUTOCLAVING
 Persons involved in steam sterilizing should be trained in
handling techniques to minimize exposure to hazards from
these wastes. These should include:
•Use of protective equipment
•Minimization of aerosol formation
•Prevention of spillage during autoclave loading/unloading
•Prevention of burns from handling hot containers
•Management of spills
 Check autoclave temperature to ensure that the proper
temperature is being maintained for a long enough period
during the cycle.
Steam sterilizers should be routinely inspected.

INCINERATION
Newly Regulated Emissions from
Medical Waste Incineration:
1. Particulate Matter
2. Carbon Monoxide
3. Dioxin
4. Sulfur Dioxide
5. Hydrogen Chloride
6. Nitrogen Oxides
7. Cadmium
8. Lead
9. Mercury

THERMAL INACTIVATION
 Thermal inactivation involves the treatment of waste
with high temperatures to eliminate infectious agents.
 This method is usually used for large volumes.
 Liquid waste is collected in a vessel and heated by
heat exchangers or a steam jacket surround the vessel.
 The types of pathogens in the waste determine the
temperature and duration of treatment.
 After treatment, the contents can be discharged into
the sanitary sewer in a manner that complies with State,
Federal, and local requirements.
 This method requires higher temperatures and longer
treatment cycles than steam treatment.

GAS/VAPOR STERILIZATION
 Gas/vapor sterilization uses gaseous or vaporized
chemicals as the sterilizing agents.
 Ethylene oxide is the most commonly used agent, but
should be used with caution since it is a suspected
human carcinogen.
 Because ethylene oxide may be adsorbed on the
surface of treated materials, the potential exists for
worker exposure when sterilized materials are handled.

CHEMICAL DISINFECTION
 Chemical disinfection is the preferred treatment for
liquid infectious wastes.
 Consider the following:
– Type of microorganism
– Degree of contamination
– Amount of proteinaceous material present
– Type of disinfectant
– Contact time
– Other relevant factors such as temperature, pH, mixing
requirements, and the biology of the microorganism
 Ultimate disposal of chemically treated waste should be
in accordance with State and local requirements.

STERILIZATION BY IRRADIATION
Advantages of irradiation:
 Electricity requirements are nominal.
 Steam is not required.
 No heat or chemicals remain the treated waste.
The principal disadvantages are as follows:
 Capital costs are high.
 Highly trained personnel are required.
 Space requirements are great.
 Worker exposure as a result of leaks in seals or poor
work practices.
 Disposal of the radiation source may pose problems.

RADIOFREQUENCY IRRADIATION
 Large radiofrequency irradiation medical waste
treatment units include an initial destruction phase.
 The waste is automatically fed into a waste grinding
device where it is shredded and sprayed with steam to
increase the moisture content of the waste to
approximately 10 percent. The moist ground waste is
then heated by exposure to radiofrequency irradiation.
This process heats the waste to >90 C.
 The factors which affect radiofrequency irradiation
treatment of medical waste include the frequency and
wavelength of the irradiation, the duration of the
exposure, destruction and moisture content of the waste
material, temperature achieved throughout the waste
load during treatment, and waste storage duration.

MICROWAVE IRRADIATION
 Large microwave irradiation medical waste treatment units
include an initial destruction phase.
 The waste is automatically fed into a waste grinding device
where it is shredded and sprayed with steam to increase the
moisture content of the waste to approximately 10 percent. The
moist ground waste is then heated by exposure to six microwave
irradiation units over a 2 hour period. This process heats the waste
to > 90 C.
 The factors which affect microwave treatment of medical waste
include the frequency and wavelength of the irradiation, the
duration of the exposure, destruction and moisture content of the
waste material, process temperature, and the mixing of waste
during treatment.

DRAIN DISPOSAL
 Some liquid medical wastes, such as human blood,
may be disposed of in sinks if the waste is first
autoclaved or brought to a final concentration of 1
percent bleach.
 The following medical wastes may not be drain
disposed:
•Human or animal cultures suspected of containing
infectious agents
•Cultures and stocks of infectious agents
•Wastes from the production of infectious bacteria,
viruses, spores, discarded live and attenuated vaccines
 Non-infectious medical waste disposal should only be
made to sanitary sewers only.

DISPOSAL OF TREATED WASTE
 Infectious waste that has been effectively treated is
no longer biologically hazardous and may be mixed with
the disposed of as ordinary solid waste, provided the
waste does not pose other hazards that are subject to
federal or state regulations.
 EPA recommends:
– Contacting state and local governments to identify approved
disposal options.
– Discharge of treated liquids and pathological wastes (after
grinding) to the sanitary sewer system. Approval of the local
sewer authority must be obtained.

CONTINGENCY PLANNING
The infectious waste management plan should include
a contingency plan to provide for emergency situations.
The plan should include, but not limited to, procedures
to be used under the following circumstances:
 Spills of liquid infectious waste – cleanup procedures,
 Protection of personnel, and disposal of spill residue
 Rupture of plastic bags (or other loss of containment)
– cleanup procedures, protection of personnel, and
repackaging of waste
 Equipment failure – alternative arrangements for
waste storage and treatment (e.g. offsite treatment).

DECONTAMINATION
 All surfaces, tools, and other objects in contact
with potentially infectious materials must be
decontaminated and as soon as possible.
 Equipment and tools must be cleaned and
decontaminated before servicing or being put
back to use.
 Decontamination should be accomplished by
using
– A solution of 5.25% sodium hypochlorite (household
bleach / Clorox) diluted between 1:10 and 1:100
with water.
– Lysol or some other EPA-registered tuberculocidal
disinfectant.

DECONTAMINATION
 To clean up spilled blood, you can carefully
cover the spill with paper towels or rags, then
gently pour your 10% solution of bleach over the
towels or rags, and leave it for at least 10
minutes.
 To decontaminate equipment or other objects
(be it scalpels, microscope slides, broken glass,
saw blades, tweezers, mechanical equipment
upon which someone has been cut, first aid
boxes, or whatever) you should leave your
disinfectant in place for at least 10 minutes
before continuing the cleaning process.
 Cleanup materials must be decontaminated.

DECONTAMINATION
Steps to Clean Up a Spill of Human Blood
 Wear gloves and lab coat to clean up spill.
 If broken glass is present, use forceps to pick
up and place in sharps container.
 Absorb blood with paper towels and discard in
biohazard waste container.
 Using a detergent solution, clean the spill site
of all visible blood.
 Wipe the spill site with paper towels soaked in
a disinfectant such as bleach diluted 1:10
 Discard all contaminated materials into
biohazard waste container.
 Wash hands with soap and water.

EXPOSURE CONTROL PLAN
 Required when employees may be exposed to
bloodborne pathogens.
 This plan should include:
 Determination of employee exposure
 Implementation of methods of exposure control, including:
- Universal precautions
- Engineering and work practice controls
- Personal protective equipment
- Housekeeping
 Hepatitis B vaccination
 Post-exposure evaluation and follow-up
 Communication of hazards to employees and training
 Record keeping
 Procedures for evaluating the exposure incident.

EXPOSURE STEPS
Despite the best precautions, exposure still can
occur. If a person is exposed to potentially
infectious materials try to minimize the exposure to
that person and others.
If a person is exposed, they should:
 Wash the exposed area thoroughly with soap and
running water (use non-abrasive, antibacterial soap
if possible).
 If blood is splashed in the eye or mucous
membrane, flush the affected area with running
water for at least 15 minutes.
 See a physician immediately.

EXPOSURE STEPS
Report the Incident —
Employees should
immediately report
exposure incidents to the
employer to permit timely
medical follow-up.

EXPOSURE STEPS
Referral to a a Health
Care Professional (HCP)
— Following a report of an
exposure incident of a
bloodborne pathogen, the
employer shall make
immediately available to
the exposed employee a
confidential medical
evaluation and follow-up at
no cost to the employee.

EXPOSURE STEPS
Documentation — The employer
must prepare a report of the
exposure incident of a bloodborne
pathogen, including the route(s) of
exposure, the circumstances
under which the exposure incident
occurred, and the identity of the
source patient — if known, and if
permitted by law.

STAFF TRAINING
 Training should include an explanation of the
infectious waste management plan and assignment of
roles and responsibilities for implementation of the plan.
 Training programs should be implemented:
 When the infectious waste management plan are first
developed and instituted.
 When new employees are hired, and
 When infectious waste management practices change.
 Continuous education is also an important part of
staff training.

MERCURY
 EPA and AHA signed a Memorandum of
Understanding (MOU).
 Lessons learned about mercury:
• The risk of mercury spills is high. The cost to remedy spills
has proven to be very expensive.
• Ninety-nine percent of a typical hospital’s mercury is
contained in esophageal dilators, sphygmomanometer
services kits, and barometers.
• Total cost to replace mercury devices is modest, especially
in light of the cost of spills.
• Non-mercury replacements are usually no more expensive
than their mercury counterparts.

MERCURY
 Removal of a mercury device must mean “get it out
of the hospital”, not merely out of service.
 Purchasing Departments and associated staff must
be vigilant in purchasing and accepting shipments of
supplies. Vendor substitution could bring mercury back
into the facility.
 Training for mercury auditing is best done on a one-
on-one basis, large groups make the process difficult.
 Mercury assessments must be performed in a safe
and open atmosphere, which encourages the discovery
of all sources of mercury.
