Dangerous properties of paint

Paint, is a Class III or 3.3 flammable liquid of the Dangerous Regulations and is toxic. Its characteristics are:

1. Highly flammable: The reason is that almost all flammable liquids are organic compounds. The molecular composition mainly contains carbon atoms and hydrogen atoms, which easily react with oxygen to burn. The flash point is low and the ignition point is low, so it is easy to catch fire and burn.

2. The flammable liquid is highly volatile. When the container containing the liquid is damaged or unsealed, the volatilized vapor volatilized out to the entire space of the warehouse or the compartment where the item is stored or carried, mixed with the air. When the concentration reaches a certain range, that is, when the explosion limit is reached, an explosion may occur when exposed to an open flame or a spark.

3, high flow diffusivity, flammable liquid molecules, viscosity is generally small, not only very easy to flow itself, but also due to penetration, infiltration and capillary phenomenon, even if the container only has very fine cracks, flammable liquid will seep Outside the container wall, the surface area is enlarged and volatilized continuously, so that the concentration of flammable liquid vapor in the air is increased, thereby increasing the risk of combustion explosion.

4, due to thermal expansion, the expansion coefficient of flammable liquid is relatively large, the volume is easy to expand after heating, and the vapor pressure also increases, which causes the internal pressure in the sealed container to increase, causing "drums" and even explosions. More than 5% of the gap should be left in the container and should not be filled.

5, toxicity, flammable liquid and its vapor have different degrees of toxicity, not only inhaled its vapor will be poisoned, and some may cause poisoning accidents through skin absorption.

Identify the type of accident: fire explosion, poisoning, container burst.
