Electric Hand Dryers: Hygiene Efficiency for Modern Sanitation Standards

Proper hand washing and drying are essential for maintaining public health, especially in commercial and public spaces where many people come and go. Commercial bathroom hand dryers offer superior economic, environmental and hygiene advantages compared to alternative hand drying methods. This article will explore the role of electric hand dryers in improving hygiene standards in commercial and public spaces.

Understanding Hand Hygiene and Drying Importance

Understanding hand hygiene is paramount in preventing the spread of infections and maintaining public health.

Hand Washing

The handwashing process involves several crucial steps: wetting hands, applying soap, scrubbing thoroughly for at least 20 seconds, paying attention to nails and between fingers, and rinsing soap under running water. Handwashing removes dirt, bacteria, and viruses, reducing the risk of illness transmission.

Hand drying

Proper hand drying is equally essential for comprehensive hygiene. Wet hands can transfer bacteria more effectively than dry ones, emphasising the necessity of thorough drying. Various hand-drying methods impact hygiene differently.

• Paper towels: Efficiently remove moisture and bacteria from hands, providing a hygienic drying option that can be easily disposed of. However, improper disposal or overflowing waste bins can pose hygiene risks in shared public spaces.
• Cloth towels require regular cleaning to prevent bacterial growth and may not be as convenient for maintaining hygiene in public settings.
• Air dryers: While environmentally friendly, some models can disperse germs into the air, potentially compromising hygiene in shared spaces.
• High-speed air dryers: Quick-drying, but their powerful airflow may contribute to bacterial dispersion, challenging their efficacy in promoting hygiene.
• Electric hand dryers: Eliminate the need for physical contact, reducing the risk of cross-contamination. Varying in effectiveness, some models may take longer to dry hands, potentially compromising hygiene, while newer models with efficient drying times can be more hygienic.

Understanding the nuances of each hand drying method is crucial for making informed choices that prioritise hygiene and mitigate the risk of infection in a particular environment.

The Benefits of Commercial Electric Hand Dryers

Compared with alternative hand drying solutions, commercial hand dryers offer several advantages for businesses and facilities. There are different electric hand dryers on the market with varying features, but all offer the following benefits:

Hygienic Advantages

Commercial electric hand dryers offer a distinct hygienic advantage by efficiently eliminating bacteria and germs. These devices utilise high-speed, warm air to rapidly dry hands, creating an inhospitable environment for microbial growth. Importantly, as they operate hands-free, the risk of cross-contamination is significantly reduced.

Unlike paper towels or cloth towels, which involve physical contact during use and disposal, electric hand dryers minimise touchpoints, ensuring a more sanitary hand-drying experience. Combined with their quick-drying capabilities, this feature makes commercial electric hand dryers a practical and hygienic choice for public spaces, promoting overall health and safety.

Environmental Impact

Commercial electric hand dryers contribute significantly to environmental sustainability. Electric hand dryers demonstrate superior energy efficiency compared to traditional methods, consuming substantially less power while delivering rapid and effective hand-drying solutions.

In comparison to paper towels, these dryers are more energy efficient. Electric hand dryers drastically reduce waste by eliminating the need for paper production, transportation, and disposal, mitigating the environmental impact of deforestation and landfill usage.

This eco-friendly approach aligns with global efforts to reduce carbon footprints, making electric hand dryers an environmentally responsible choice for businesses. The reduction of waste and enhanced energy efficiency positions these dryers as a green alternative, fostering a more sustainable and eco-conscious approach to hand hygiene in commercial settings.

Cost Effectiveness and Economic Advantages

Commercial electric hand dryers offer cost-effectiveness and economic advantages for businesses. While the initial investment may be higher than purchasing paper towels, the long-term savings are substantial.

Electric hand dryers have lower maintenance costs, requiring fewer refills and less frequent servicing than paper towel dispensers. Additionally, the operational cost of electricity for hand dryers is generally lower than continuously restocking paper towels. Over time, businesses and facilities experience significant financial benefits, making electric hand dryers an economical choice for sustainable, cost-efficient hand hygiene.

Installing Electric Hand Dryers: Considerations and Best Practices

Installing electric hand dryers requires careful consideration of location, compliance, and user experience.

Installation Areas

IEE Wiring Regulations (BS7671) significantly influence hand dryer placement in washrooms, specifying locations based on the IP rating. IP ratings indicate resilience to water and particles, with the first digit denoting solid resistance and the second liquid. Check the IP rating before installing near sinks or showers; a rating ending in 1 should be 60cm away from water sources. Some dryers with IPx4 ratings allow placement within this range if necessary, ensuring compliance with safety standards in the proximity of water-based fixtures.

User Experience

User experience is paramount, and considerations for different demographics must be given. Installing bathroom hand dryers at varied heights accommodates users with diverse needs, including children and individuals with disabilities. Furthermore, choosing models with quick drying times enhances the overall user experience, promoting satisfaction and encouraging consistent hand hygiene practices.

Recommended hand-under dryer heights for optimal usability:

Adult Males: 117cm

Adult Females: 112cm

Children (4–7 years): 81cm

Children (7–10 years): 91cm

Children (10–13 years): 102cm

Adolescents (13–17 years): 112cm

Disabled Users: 94cm

These measurements, from the air nozzle to the floor, ensure convenient and accessible hand drying for individuals of different age groups and abilities.

Installation Hygiene Considerations

Managing the invisible war on germs in your facility is crucial. The placement of bathroom hand dryers directly impacts hygiene, so focus on separating toilet and handwashing areas. Installing dryers too close to urinals risks urine splashes, potentially spreading harmful pathogens. Consider investing in the most hygienic hand dryer with fast-drying technology in heavy-use washrooms for optimal germ control and user safety.
