7. Naphthalene Balls
Many people use naphthalene balls, also known as moth balls, when packing away wool clothes. They protect your clothes from being gnawed away by moths and other insects.
Some people also use these naphthalene balls to spread over their gardens and basement floors to keep away insects, birds and rodents.
However, exposure to naphthalene balls can prove harmful. A 2000 study published in the National Toxicology Program Technical Reports Series notes that a 2-year exposure to, and inhalation of, the naphthalene from naphthalene balls triggered cancerous activity in male and female rat models.
You may unknowingly inhale the naphthalene, absorb it through your skin and rub it into your eyes after touching naphthalene balls.
Long-term exposure to this toxin can cause nausea, abdominal cramps, anemia, retinal and cataract disorders, and cancer.
8. Clothes Dryer
Approximately 2,900 clothes dryer fires occur in the U.S. each year and cause around 5 deaths, 100 injuries and $35 million worth of property loss, according to a 2012 study published in the Topical Fire Report Series.
When we wash clothes, especially heavier clothes like winter garments and blankets, they shed off lint. People assume their dryers catch all the lint in the lint trap.
However, that does not happen. Over time, washing and repeated shedding causes a lint buildup all over the dryer. Lint is highly combustible.
Furthermore, the dryer exhausts moisture and heat when in use. When it is clogged, it cannot properly exhaust and goes into overdrive.
This, in turn, causes it to produce more heat without any vent. The excessive heat, coupled with the lint buildup, sparks a fire.
