According to reports, the main chemical composition of paint is xylene, esters, ketones, alcohols, ethers and other low-boiling organic solvents, of which xylene is common in all types of paint. The above explosions and poisonings were caused by the accumulation of high concentrations of xylene in the room. Benzene is a colorless liquid with a special aromatic odor. The boiling point is 80.1°C and xylene belongs to the benzene homologue. At present, xylene is used as a solvent or thinner for various glues, paints, coatings, and waterproof materials in the interior decoration. Benzene is volatile, flammable, and vapor explosive. When a person inhales a high concentration of xylene in a short period of time, an anesthetic effect of the central nervous system may occur. The light person may suffer from dizziness, headache, nausea, chest tightness, fatigue, and confusion. In severe cases, he may become unconscious and die due to respiratory and circulatory failure.
Experts remind construction workers who are currently renovating to pay attention to the following issues in the summer hot weather construction:
First, the paint must be done in accordance with the specifications of the construction requirements, that is, in a dry and ventilated environment. Humidity in the room can affect paint film formation and paint luster. Ventilation can quickly disperse volatile, flammable and harmful gases.
Second, paint, paint construction is most afraid of wind and sand weather, due to dust falling on the paint film will affect the brushing effect, therefore, this construction is generally carried out in the case of closed doors and windows. If the brushing amount is large, the indoor temperature is high, and the construction time is long, the xylene gas accumulated in the indoor air is too high, and poisoning may result. In the event that windy weather does not meet ventilation requirements, be careful not to stay too long in a closed room.
Third, some projects avoid mixing together. Do not paint construction items such as paints and coatings with woodworking jobs such as furniture, heating, and wood flooring.
Fourth, material stacking should be classified. Wood, paint, paint, and other materials should not be mixed together or in one room and should be placed separately. Paints and other flammable materials should be stored in ventilated areas.
V. No smoking or cigarette butts at the construction site.
6. Fire extinguishers should be prepared at the construction site.
