Final answer:
When a vaporizer is too close to the skin or left on the skin too long, it can result in contact with harmful chemicals, causing damage or absorption into the bloodstream. Avoid prolonged exposure to vaporizers on the skin to prevent risks of irritation, burns, or chemical poisoning.
Step-by-step explanation:
When a vaporizer is allowed to be too close to the skin or left on the skin too long, it can result in skin or eye contact with chemicals. This can lead to damage to the skin or absorption of the chemicals into the bloodstream through the skin. For example, if a person uses a vaporizer with harmful chemicals near their skin for an extended period, it can cause irritation, burns, or even chemical poisoning. It is important to use vaporizers according to instructions and maintain a safe distance from the skin to avoid these risks.
