Does Ethylene Oxide Kill Viruses?

Does ethylene oxide kill viruses?

Ethylene oxide is capable of destroying most viruses

, bacteria, and fungi, including bacterial spores. It reacts with protoplasm, DNA, and proteins and deactivates enzymes and other biologically important components of a living organism. Ethylene oxide is more effective in killing microorganisms under dry conditions.

Is ethylene oxide a disinfectant?

Currently,

ethylene oxide gas is used to sterilize 50% of all medical supplies that require that high level of disinfection

— everything from plastic surgical gowns to syringes, catheters, bandages, gauze, and pacemakers.

What microbes does ethylene oxide kill?

Ethylene oxide is used as a sterilant and kills

all bacteria (including spores) and fungi

.

Is it safe to sterilize with ethylene oxide?

Is ethylene oxide a disinfectant or sterilant?

ETO is used in healthcare facilities to

sterilize

critical items (and sometimes semicritical items) that are moisture or heat sensitive and cannot be sterilized by steam sterilization.

Do hospitals use ethylene oxide?

Ethylene oxide (EtO) gas sterilizers have been used by hospitals for over 40 years

to sterilize surgical equipment and supplies that are heat sensitive or that cannot tolerate excessive moisture.

Is ethylene oxide harmful to human health?

Exposure to ethylene oxide

may cause headache, nausea, vomiting, diarrhea, breathing difficulty, drowsiness, weakness, exhaustion, eye and skin burns, frostbite, and reproductive effects

. Workers may be harmed from exposure to ethylene oxide. The level of exposure depends upon the dose, duration, and work being done.

What is ethylene oxide commonly used for?

At room temperature, ethylene oxide is a flammable colorless gas with a sweet odor. It is used primarily

to produce other chemicals, including antifreeze

. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent.

How long does ethylene oxide sterilization last?

Ethylene oxide can last in the air for weeks

and can be transported with prevailing winds. At higher temperatures, especially above 50 degrees Fahrenheit, and stronger winds, we would expect ethylene oxide to transport farther away from the emission source more effectively.

Why is ethylene oxide considered an acceptable chemical sterilant?

Why is ethylene oxide considered an acceptable chemical sterilant?

It is reliably sporicidal

.

Is ethylene oxide banned in the United States?

Some states such as California and Michigan require an EO abator be installed to reduce EO emissions, but

EO is not banned

(a common misconception). The 3MTM EO Abator reduces EO emissions virtually eliminating any emissions to the environment. Is ethylene oxide sterilization safe for patients and staff?

How much ethylene oxide is safe?

► Ethylene Oxide may polymerize (self-react) violently. OSHA: The legal airborne permissible exposure limit (PEL) is

1 ppm averaged over an 8-hour workshift and 5 ppm, as an excursion limit, averaged over a period of 15-minutes

.

Do dentists use ethylene oxide?

Ethylene oxide gas has been utilized as an alternative method for sterilization of dental handpieces

, as it is less corrosive than steam. However, its effectiveness for sterilization of the internal components of dental handpieces has not been established.

Which disinfectant is the most effective at stopping bacterial growth?

Glutaraldehyde is considered one of the most effective disinfectants for hospital use.

What everyday products contain ethylene oxide?

EtO is found in the production of

solvents, antifreeze, textiles, detergents, adhesives, polyurethane foam, and pharmaceuticals

. Smaller amounts are present in fumigants, sterilants for spices and cosmetics, as well as during hospital sterilization of surgical equipment.

What household products contain ethylene oxide?

Ethylene oxide is used to make a variety of products found all around your house – from

shampoos to disinfectants to laundry detergent

. It is also a necessary ingredient for some highly durable fabrics and textiles used in clothing, carpet, upholstery, and pillows.

What are the 3 types of sterilization?

• Steam Sterilization. Steam sterilization (aka autoclaving) can be characterized as an effective, fast, safe, and affordable option for sterilization. …
• Dry Heat Sterilization. A thermal processing option commonly used is dry heat sterilization. …
• Ethylene Oxide (EtO) Sterilization.

How do you sterilize a cotton swab at home?

Does ethylene oxide leave residue?

What happens if you eat ethylene oxide?

Because ethylene oxide destroys DNA, it can

increase the risk of certain cancers

. Studies show that long-term exposure to ethylene oxide can cause cancers of the white blood cells in humans, including non-Hodgkin lymphoma, myeloma and lymphocytic leukemia, according to the EPA.

Why is ethylene oxide used in food?

Ethylene oxide is used in the dried fruit industry

to stop microbial spoilage in prunes

and, presumably, these treatments are also insecticidal. Ethylene oxide has been used for over 40 years for both insecticidal treatments and for the sterilization of foodstuffs.

Is there ethylene oxide in cigarettes?

Ethylene oxide (EO) is a metabolite of ethylene, also

found in cigarette smoke

, and is carcinogenic in rodents.

How is ethylene oxide removed after sterilization?

What chemical agent is commonly used for sterilization in hospitals?

Common chemical sterilants used in healthcare

¹

include:

Ethylene oxide (EtO) Hydrogen peroxide gas plasma (HPGP) Vaporized hydrogen peroxide

.

Does formaldehyde sterilize?

Low-temperature steam with formaldehyde is used as a low-temperature sterilization method in many countries, particularly in Scandinavia, Germany, and the United Kingdom

. The process involves the use of formalin, which is vaporized into a formaldehyde gas that is admitted into the sterilization chamber.

Is ethylene oxide used in antifreeze?

What is ethylene oxide? Ethylene oxide is a flammable gas that dissolves readily in water.

It is a man-made chemical used primarily to make ethylene glycol (a chemical used to make anti freeze and polyester)

.

How can you protect yourself from ethylene oxide?

What devices are sterilized with ethylene oxide?

Medical devices made from certain polymers (plastic or resin), metals, or glass, or that have multiple layers of packaging or hard-to-reach places (for example, catheters)

are likely to be sterilized with ethylene oxide.

Which of the following are disadvantages of using ETO?
