Can UV Lamps Help Protect My Restaurant?

 

For more than a year, businesses and global economies have been negatively affected by the COVID-19 pandemic, with restaurants forced to shut down or limit capacity in nearly every state across the country. With the vaccination rollout and a light at the end of the tunnel, states are loosening restrictions with more business openings. Business owners and owners of restaurants everywhere are searching for ways to ensure the safety of their staff and the public. 

Restaurants have increased manual cleaning methods such as wiping down surfaces and counters with antibacterial disinfectant cleaners, forcing mask mandates and practicing social distancing. Many restaurant owners want to know if UV lamps will help them provide a cleaner and safer environment. UVC germicidal lamps are an excellent, effective, and reliable tool that drastically improves disinfection and sterilization goals with many unique, additional benefits for restaurant owners. 

UVC Lamps Provide a Host of Benefits for Restaurants

UVC germicidal lamps for restaurants serve many purposes to improve sterilization processes and safety for staff and patrons.  UV lamp technology can be used in many areas and devices to sterilize the air in public dining places, restrooms, and kitchens. UV lamps sterilize surfaces in restaurants and commercial kitchens to prevent the spread of disease on counters and utensils, and can also be used for food irradiation, a safe and effective method of preventing foodborne illnesses.  

Food Irradiation

Food irradiation with UVC lamps is an approved method by the FDA to tread many food types such as:

• Fruits and vegetables 
• Meats and poultry
• Various dairy products
• Beverages 

UV Surface Treatment

UV surface treatment in restaurants helps to eliminate foodborne diseases such as E. coli and Salmonella.  UV lamps can be placed above food buffets, delis, food preparation counters, and food storage areas. 

UV Lamps for Walk-in Freezers

UV lamps help to prevent mold and mildew in areas susceptible to excessive moisture such as a walk-in freezer. 

UV Lamps in Kitchen Hood Exhausts

UV lamps in commercial kitchen hood exhausts prevent the build-up of grease, thus reducing the risk of fire and increasing cleanliness.  

Upper Room Air Disinfection

Restaurants can incorporate upper room Ultraviolet Germicidal Irradiation (UVGI) in UV air sterilization units mounted in public areas, restrooms, and kitchens.  UV lamps may also be incorporated into HVAC systems providing a continual defense against spreading airborne disease.

UVC lamps are an important tool in helping to prevent the spread of harmful viruses, bacteria, mold, mildew, fungi, and other harmful pathogens. Ultraviolet radiation is proven effective in sterilizing water, surfaces, and air in a variety of UV sterilization devices including UVC robots, HVAC applications and various water and surface sterilization systems.

Do UV Lamps Kill the SARS-CoV-2 Virus That Causes COVID-19?

 

Ultraviolet (UV) light is a type of electromagnetic radiation that has more energy than visible light but less energy than x-rays and gamma rays. UV light from the sun is replicated in UV lamps for things like tanning beds and disinfection applications. UV light is broken down into different spectrums mainly UVA, UVB and UVC light. 

UVC light is the wavelength with germicidal effectiveness and is mostly absorbed by the Earth’s ozone layer before it reaches the ground. UVC germicidal lamps are designed to emit wavelengths at the optimal nanometer to kill germs which is typically 254 nm or 185 nm for ozone lamps.  According to the study Upper-room ultraviolet air disinfection might help to reduce COVID-19 transmission in buildings: a feasibility study by the National Institutes of Health, several studies have demonstrated that the SARS-CoV-2 virus that causes COVID-19 is relatively easily inactivated by UVC disinfection lamps similar to other airborne coronaviruses.  Additionally, conclusions from this study state that Upper Room Ultraviolet Germicidal Irradiation (UVGI) with UV light at 254 nm has the potential to inhibit the transmission of COVID especially in confined places like hospital rooms or public places or anywhere that achieving a high ventilation rate is not practical.

UV Lamps in HVAC Systems Fight Spread of Disease

 

The use of ultraviolet (UV) light in disinfecting and sterilizing surfaces is gaining as part of the fight against the spread of the novel coronavirus and to control health acquired infections (HAIs) in hospitals. HAIs are a serious problem for hospitals, especially when stretched at capacity and short on staff.  Even prior to the COVID-19 pandemic, nearly 1 in 25 patients were estimated to contract an HAI from a hospital stay, some with dire consequences. Protecting patients and staff against HAIs including drug-resistant bacteria and serious viruses with effective hospital disinfection is top priority for hospitals and healthcare facilities. 

Nearly everything that is in a hospital room from all the surfaces to airborne particles, medical equipment and the clothing and hands of healthcare workers can serve as a reservoir and vector for transmitting opportunistic pathogens.  While contaminated surfaces and insufficient hand hygiene are the primary modes of transmission, water and air supply systems also provide a mode of transmitting harmful pathogens.

UVC HVAC Air Purification Systems

While maintaining regular cleaning and manual disinfection practices is crucial in hospitals, along with proper hand hygiene, germicidal UVC lamps in moving air applications are proven to disinfect and purify the air. Ultraviolet Devices, Inc, UVDI, offers HVAC air disinfection and purification systems with advanced UV technology. UV air disinfection eliminates viruses and bacteria with a kill rate up to 99% and UV air purification destroys volatile organic compounds (VOCs) and foul odors.

UV moving air applications include two basic systems for UVGI as a supplemental air cleaning measure:

Upper room air irradiation – UVGI lamps are wall mounted above an occupant’s level, usually 8 feet above the floor and irradiate the airflow in the room.  Upper room UVGI has been used in tuberculosis wards to inactivate TB and is also effective in patient rooms, emergency rooms, waiting rooms, hallways and anywhere patients could potentially spread airborne germs.

HVAC Duct Irradiation – UVC germicidal lamps placed inside HVAC and air handler ducts disinfect recirculated or outside air. UVC lamps in air handling units effectively eliminate microscopic organisms that are too small to filter yet are easily disinfected with UV light.

LightSources offers high-quality UVC lamps found in UV sterilization systems for hospitals including air disinfection UVGI mounted, HVAC and portable systems  Our UVC robot lamps are helping hospitals to improve patient and staff safety and prevent the spread of disease with effective surface sterilization.

Does Ultraviolet Radiation Kill the COVD-19 Virus?

 

Ultraviolet radiation is proven to kill viruses and bacteria and there have been many questions about the efficacy of UV light killing the novel coronavirus.  The current pandemic with the outbreak of COVID-19 is caused by the coronavirus SARS-CoV-2, and people want to know if they can purchase UV lights for their home to help protect themselves and their family with effective sterilization.  Hospitals have been using UVC lamps in surface sterilization devices and UVC robots to further sterilize patient rooms and surfaces.

The U.S. Food and Drug Administration, FDA, answers your questions about UV Lights and Lamps: Ultraviolet-C Radiation, Disinfection, and Coronavirus. 

UVC Radiation and the SARS-CoV-2 Coronavirus

UVC radiation is proven to destroy the SARS-Coronavirus, which is a different coronavirus than what causes COVID-19.  SARS-CoV-2 is the virus that causes COVID-19 and given the newness of the virus there are many ongoing research studies to verify accurate dosage of UVC exposure including exposure duration and distance, which is key to effective sterilization with germicidal UVC lamps. 

Studies like this one by Boston University are showing promise with results that show a 99% reduction of the SARS-CoV-2 virus when UVC radiation is dosed at the right level.  This study shows that UV light will deactivate the coronavirus in 6 seconds when dosed at 5 mJ/cm2.  Another study conducted by Biological Consulting Services in Feb.2020, shows effective elimination of SARS-CoV-2 virus and many other stubborn microorganisms in UVGI irradiation with 99.99% effectiveness with 15 minutes of exposure.  With surface sterilization at direct exposure and UVGI air irradiation, hospitals can significantly improve the health of patients and prevent the spread of disease. 

Hospitals using UVC light to eliminate the spread of disease and consumers wishing to purchase UVC lamps to sterilize surfaces at home must remember that direct exposure is key.  UVC radiation will only kill microorganisms that are directly exposed to the UVC radiation emissions.  Inactivation of the virus on surfaces will not be as effective if blocked by shadows, dust, soil or organic compounds which absorb the UV light and reduce the efficacy of sterilization on the surface.

UV Light Prevents Grease Build Up in Kitchen Exhaust

 Kitchen hood exhaust systems in commercial kitchens serve a very important purpose, to pull grease particles up and away through mechanical filters.  Kitchen exhaust systems vent excess heat above kitchen stoves and extract grease particles, leaving smaller particulates that may linger in the hood exhaust system.  These kitchen exhaust systems can encounter grease build-up in the vents if they are not cleaned regularly or treated with UV light sterilization solutions. 

How Does UV Light Help Kitchen Hood Exhausts?

Ultraviolet (UV) light emits UV radiation, electromagnetic energy, and is harnessed in UV germicidal lamps used in a vast range of applications.  UV light is used to purify the air, disinfect water and sterilize surfaces.  Utilizing UV light in kitchen hood exhaust systems provides many benefits beyond sterilization.  Kitchen hood UV exhaust systems can actually prevent grease build-up in the exhaust duct work.  

UVC lamps break down grease through photolysis and ozonolysis. UV light causes a photochemical reaction, breaking down the molecular bond while ozonolysis oxidizes the grease molecules. By breaking down the grease particles, they are converted into particles that are much easier to clean and do not build-up grease in the kitchen hood.  

This brings many benefits to restaurant owners by mitigating the risk of a grease fire, which can often occur with grease build-up in the exhaust hood.  UV kitchen exhaust systems also help kitchens to meet stringent health department code regulations by helping to keep the kitchen cleaner.  This provides a better work environment for employees and helps to maintain health standards for patrons. 

UV Lamps are Key to Successful UV Sterilization Systems

Using the right UV lamps for your UV kitchen exhaust sterilization system is key to successful prevention of grease build-up and sterilization.  UV germicidal lamps designed to emit 254 nanometer (nm) are effective in sterilizing air and surfaces.  Ozone producing lamps emit UV energy at 185 nm and are commonly used in air and water disinfection applications, deodorizing the air and reaching places that standard UV radiation cannot reach. 

When searching for the best UV lamps for your sterilization application, contact an experienced UV lamp manufacturer like LightSources. 

LightSources leads the industry in UVC germicidal lamp production, with a wide range of low-pressure, amalgam and many other lamp types designed with proprietary technology.  We provide high-quality UVC lamps proven to outlast and outperform comparable lamps of the same size.  Contact us to learn more and for custom lamp requirements for your UV germicidal application.

Solutions for Challenges Facing Hospital Disinfection

 Disinfection practices in hospitals have always been of great concern with the number of patients carrying viruses and bacteria, and the potential exposure to patients with compromised immune systems.  Hospital acquired infections are infections that occur within the first 48 hour of being admitted to the hospital, within the first three days following a hospital discharge or within the first 30 days after an operation.  The Center for Disease Control, CDC, estimates that approximately one in every 25 of hospital patients in the U.S. contracts a hospital acquired infection (HAI).  Many HAIs are resistant to treatment with antibiotics and can lead to sepsis or even death. 

HAIs and disinfecting patient rooms are of great concern for hospital staff for many reasons:

• Patients being discharged may have had a contagious, serious viral or bacterial infection

• Incoming patients are already ill and may have a compromised immune system

• Hospital staff move from room to room and have a high potential to carry pathogens from one patient room to the next

Hospital Cleaning Practices

Hospitals take their cleaning, sanitizing and disinfecting practices very seriously. Even with the most careful cleaning procedures, human error can contribute to less than sanitary conditions. Disinfecting patient rooms thoroughly can be challenging due to many factors such as:

• Using contaminated cloths which spread disease

• Using diluted disinfectant cleaning solutions

• Insufficient contact time of cleaners with surfaces

• Human error, cleaning staff can miss an area when manually cleaning

Adding UV Light Disinfection

Adding UV light disinfection to standard hospital cleaning practices has been proven to greatly increase sterilization success. UV light in shortwave UVC radiation quickly eradicates many viruses and bacteria with high efficacy and can reach into places that manual cleaning cannot access.  

UV germicidal lamp manufacturers design and engineer UVC lamps to emit the most powerful wavelength of UVC radiation at 254 nanometer.  UVC radiation penetrates the cells of viruses and bacteria, rendering them unable to replicate and leaving them harmless. High-quality UVC germicidal lamps are the key to effective UV sterilization.

LightSources is a leading global supplier of UVC germicidal lamps, with a wide range of UV germicidal lamp types.  We offer standard low-pressure mercury lamps, amalgam lamps with proprietary technology, Germipak, U-lamps and custom engineered solutions.  Contact us to learn more about our high-performance UV germicidal lamps.

How UV Light Keeps Kitchens Clean

 

Ultraviolet (UV) is a powerful disinfectant used in many applications to sterilize water, air and surfaces.  High intensity UV lamps eliminate harmful pathogens and break down volatile organic compounds (VOCs).  UV radiation in the wavelength of UVC ultraviolet light is highly effective at eradicating bacteria, viruses, mold, mildew and can even break down grease buildup.  UVC germicidal lamps are being used in many residential, industrial and commercial applications such as restaurants and kitchens. 

UVC germicidal lamps can help to keep restaurants and kitchens clean in many areas such as:

• UV air purification for healthy air in eating areas

• UV surface sterilization over food preparation areas

• UV lamps prevent mold and mildew in walk-in freezers

• UV food irradiation to prevent foodborne illnesses

• UV lamps in kitchen exhaust to prevent grease buildup

Commercial kitchens utilizing UV germicidal lamps in kitchen hood exhaust systems experience cleaner kitchen exhaust without grease buildup which also reduces the risk of kitchen grease fires.  Kitchen hood exhausts with UVC lamps provide low-maintenance, self-cleaning technology to help restaurant owners provide a cleaner and safer kitchen and to meet stringent health department code regulations. 

How UV Lamps Eliminate Grease Buildup

UV lamps eliminate grease buildup through a chemical reaction called photolysis and ozonolysis.  Photolysis, or photodissociation, occurs when photons break down oxygen molecules to oxygen atoms, which combine with remaining oxygen molecules to form ozone. Ozone causes a reaction with the organic compounds found in the grease through a process called ozonolysis. Ozonolysis forms byproducts which are easier to clean and reduces grease deposits and buildup in kitchen hood exhaust and duct systems.
