Why is cleaning your hands so important?
• Studies show that infection causing bacteria are frequently spread through the hands
One gram of human feces can contain
10 million viruses and one million bacteria
One gram of garden soil harbors
10,000,000 (107) bacteria including viruses which include both harmful and non harmful

1. THESE DISEASES ARE SPREAD THROUGH THE INGESTION OF VANISHING AMOUNTS OF FECAL MATERIAL.
2. THESE DISEASES CAN BE PREVENTED WITH
GOOD HAND WASHING?
SALMONELLOISIS

1. People with heavy workloads
A recent study showed that the busier workers are, the less likely they are to wash their hands when recommended

• Sinks not located
• Sinks located but not functioning
• Sinks inconveniently located
2. Location of Sinks

Frequent hand washing causesskin irritation and dryness.
In the winter cracks in their skin that cause bleeding
3. Damage to Skin

4. Many people don’t realize they have germs on their hands (Hands Look Clean)
Workers can get 100s or 1000s of bacteria on their hands by doing simple tasks, like
Culture plate showing growth of bacteria 24 hours after a worker placed her hand on the plate

Does handwashing really
reduce the spread of bacteria?YES!
A scientific study found that when people did not wash their hands between contacts, have more bacteria than people who washed their hands with an antimicrobial soap.
Several other studies also show that washing hands between contacts reduces the spread of bacteria .

A composition is formulated with generally regarded as safe (GRAS) ingredients for use as a non-radio-active simulant of radiological contamination.
The compositions can be used for training exercises, testing, and research studies, and they can be applied safely to human skin.
‘Glow Germ demo,’ to demolish the myth,
‘Visible clean is safe clean’ and demonstrate
‘Water is not enough.’
