a human skin burn evaluation system
Generally, a human skin burn evaluation system is established according to the depth of skin tissue destruction and the degree of tissue necrosis. The system mainly divides skin burns into four levels
(1) First-level burns are burns on the surface of the skin. Burns only occur in the epidermis. It is characterized by redness and pain on the skin surface, but no blisters from burns. The skin burns usually seen under the strong sunlight in summer are first-degree burns.
(2) Secondary burn is the destruction of the entire skin epidermis. It can be divided into surface secondary burn and deep secondary burn. The surface second-level burns do not damage the dermis, and the skin is red and blistered; while the deep second-level burns will damage part of the dermis, and the bottom of the blisters produced after skin burns is pale.
(3) When the skin reaches third-level burn, the entire dermis layer will be destroyed, and the degree of necrosis will extend to the subcutaneous tissue. It is characterized by dry and white skin, but no blisters. It is an irreversible burn, and the skin loses consciousness after the burn.
(4) Skin transplantation is required after fourth-degree burns; fifth-level and sixth-level burns damage the composition of muscles and bones, respectively.
Among all kinds of protective clothing, thermal protective functional clothing is one of the most widely used varieties. It refers to personal protective equipment that can be worn in high-temperature environments and can promote human body heat emission, prevent heat stroke, burns and burns. , Its role is to protect the human body from all kinds of heat damage, such as convection, conduction heat, radiant heat, molten metal sputtering and hot steam or hot gas damage.
The flame retardant protective clothing produced by DROTEX can effectively avoid serious burns to human skin. In the event of a fire, the flame resistance of the flame retardant clothing can give the human body enough time to escape from the scene and take off the burning clothing.
