from typing every hour. Keep elbows close to your

Ozone, or trioxygen, is a triatomic molecule, consisting of three oxygen atoms. It is an allotrope of oxygen that is much less stable than the diatomic allotrope (O2).

Ozone in the lower atmosphere is an air pollutant with harmful effects on the respiratory systems of animals and will burn sensitive plants; however, the ozone layer in the upper atmosphere is beneficial, preventing damaging ultraviolet light from reaching the Earth's surface.

Ozone is present in low concentrations throughout the Earth's atmosphere. It has many industrial and consumer applications.

OZONE IRRITATION

Health experts have suggested that ozone emitted from laser printers can lead to breathing problems.

SolutionIt is recommended that laser printers should be situated at least one meter away from where people are sitting and there should be good ventilation in the area.

People must be careful with they use they give to technology. If people are well informed about the health problems the constant use ofgthecnology generates they can take preventive measures.

Mainly the solution is to be aware of the problem.
