The main contact of spray painting is paint or benzene. Short-term high-concentration exposure to benzene can lead to acute benzene poisoning, mainly manifested as neurasthenia syndrome such as dizziness, headache, fatigue, insomnia and memory loss. Long-term exposure to benzene will lead to chronic benzene poisoning, which mainly affects the blood system and can lead to leukemia.

Suggestion:

How many years can you do this? There are no special rules, but you should pay attention to the ventilation of the working environment and wear a mask to protect yourself. The unit should arrange regular physical examination every year. If it is found that the white blood cells in blood routine are low, it is necessary to change the body position in time. Seriously, you need medication.

I hope my advice is useful to you. Pay attention to protect yourself and wish you good health.
