Dust from painting

For at least a century, the chemical industry performed an enormous experiment on health and, even though the companies were only subject to legal consequences and effects after many years, the damage was done and is irreversible.
Today paints do not include lead, but until 50 years ago it was the material that was used the most in all products including toys, pots and pans, furniture, and general industrial structural work.
Workers in contact with this pigment suffered terribly after inhaling the lead dust present in the air in the workplace.

Since the 80s, the use of lead in paints is forbidden but it is still used along with fuel in aeroplanes.
The greatest risk is that many hazards are invisible.
Heavy metals get into our bodies through the respiratory tract from car exhaust, each time we paint or remove paint, when we use glues, solvents, etc.
The health effects are varied and should not be underestimated. The respiratory tract and skin are most affected. Continuous inhalation of solvents can also cause damage to the nervous system. There have been cases of lung cancer in people who have come in contact with barium chromate, strontium chromate, lead chromate, and lead sulfochromate yellow pigments.

In particular, the painter tends to underestimate the risks involved in the work due to habit or to save time, such as not wearing a mask when spraying paint.
During painting activities, workers may come in contact with chemical agents that transport solvents, paint, etc. In particular, when spray painting, particles of the product are dispersed in significant quantities.
For safety, products must be stored in a dry or wet painting booth that is pressurized and equipped with a specific extraction system for painting dust.
The pressurized room is connected to the painting booth.

The room is built with thermal insulation panels and an air filter plenum structure located in the ceiling of the room that is connected to the pressurization unit for the air entering the room.
The painter can then paint the piece without interruptions and without breathing in the paint fumes since part of the paint will end up on the piece, part will end up in the air and will be drawn out of the booth, and part will be neutralized by the filters or other systems located in the booth.
Personal exposure is a public health problem throughout the world. Miners and painters are only two of the occupations identified as having a high risk of toxicity that is potentially hazardous to health.
