Problems to be Solved by the Invention

[0004] The hood of the protective clothing is provided with a front opening for exposing the face of the wearer. When wearing the protective clothing, it is necessary to cover the boundary between the front opening of the hood and the full-face mask with a binding material to ensure the airtightness of the protective clothing.

[0005] However, the conventional protective clothing has a problem that the wearer's ease of movement and comfort when worn together with the full-face mask are not good.

[0006] The present invention provides an asbestos work protective clothing and an asbestos work method that can improve the ease of movement and comfort of a wearer when wearing the protective clothing together with a full-face mask.

Means for Solving the Problems

[0007] The asbestos protective suit according to the present invention is a protective suit to be worn together with a full-face mask, wherein the protective suit has a hood that covers the wearer's head, the hood has a front opening that exposes the wearer's face, and the dimensions of the front opening are 30 cm in height and 32 cm in width.

[0008] The asbestos work method according to the present invention is a method of performing asbestos work while wearing a full-face mask and protective clothing, wherein the protective clothing has a hood that covers the wearer's head, the hood has an oval-shaped front opening that exposes the wearer's face, the dimensions of the front opening in its natural state are 30 cm in height and 32 cm in width, and the work is performed by putting the full-face mask on the wearer's head, then putting the hood over it, making sure the periphery of the front opening is in close contact with the rear periphery of the full-face mask, and sealing the boundary between the periphery of the front opening and the full-face mask. [Effects of the Invention]

[0009] According to the protective clothing and asbestos work method of the present invention, the ease of movement and comfort of the wearer when wearing the protective clothing together with a full-face mask can be improved, and consequently, the work efficiency and safety of asbestos work can be improved. [Brief explanation of the drawing]

[0010] [Figure 1] This is a front view illustrating the wearing of an asbestos protective suit according to one embodiment. [Figure 2] This is a plan view of an asbestos work protective suit according to one embodiment. [Figure 3] This is an enlarged view of the main part of Figure 2. [Figure 4] This is a flowchart illustrating one embodiment of an asbestos removal method. [Modes for carrying out the invention]

[0011] Embodiments for carrying out the present invention will be described with reference to the attached drawings. [Protective clothing for asbestos work] As shown in Figure 1, one embodiment of the asbestos work protective suit (hereinafter also simply referred to as "protective suit") 10 is a so-called jumpsuit-type protective suit worn together with a full-face mask 20. The protective suit 10 has a hood 11 that covers the wearer's head. A slide fastener 13 that can be opened and closed is provided in the left-right center of the front of the protective suit 10. The full-face mask 20 integrally comprises a large eyepiece 21 for ensuring a wide field of view, a breathing piece 22 with a built-in filter, and an annular mask body (not shown) that can be airtightly fitted to the face. The mask body (not shown) extends rearward (towards the face) from the eyepiece 21.

[0012] As shown in Figure 2, the hood 11 has a front opening 12 that exposes the wearer's face. The peripheral edge 21a of the front opening 12 is the part that adheres closely to the outer surface of the rear peripheral edge of the full-face mask 20 (near the boundary between the mask body and the face), so it needs to have some degree of elasticity to accommodate differences in the dimensions of the rear peripheral edge of the full-face mask 20 (differences depending on the manufacturer, etc.). For this purpose, the peripheral edge 21a of the front opening 12 has elastic (not shown) built in so as to border its entire circumference. Because the peripheral edge 21a of the front opening 12 is narrowed by the elastic, the opening area of ​​the front opening 12 in its natural state (see Figure 2) is smaller than the maximum opening area (see Figure 3).

[0013] The slide fastener 13 extends from the lower end of the front opening 12 to the vicinity of the crotch. The slide fastener 13 is fully open when the slider (not shown) is moved to its lower limit (near the crotch) and fully closed when the slider (not shown) is moved to its upper limit (lower end of the front opening 12).

[0014] As shown in Figure 3, the shape of the front opening 12 is elliptical. The vertical dimension H of the front opening 12 is 30 cm, and the horizontal dimension W is 32 cm. Dimensions H and W are those obtained when the front opening 12 is opened to its maximum opening area without stretching the fabric of the hood 11 itself.

[0015] In this way, by setting the vertical dimension H of the front opening 12 to 30 cm and the horizontal dimension W to 32 cm, it is possible to improve the ease of movement and comfort of the wearer when wearing the protective suit 10 together with the full-face mask 20. Specifically, although the dimensions of the full-face mask 20 vary depending on the manufacturer, by setting the vertical dimension H of the front opening 12 to 30 cm and the horizontal dimension W to 32 cm, it is possible to improve the ease of movement and comfort of the wearer when wearing the protective suit 10 with full-face masks 20 from all manufacturers currently in production.

[0016] More specifically, if the vertical dimension H of the front opening 12 is greater than 30 cm and the horizontal dimension W is greater than 32 cm, the dimensions of the front opening 12 are too large for all currently produced full-face masks 20 from all manufacturers. As a result, when the boundary between the periphery 12a of the front opening 12 and the full-face mask 20 is sealed with a sealing material, unnatural wrinkles are created in the hood 11, reducing the wearer's ease of movement and comfort.

[0017] Furthermore, if the vertical dimension H of the front opening 12 is greater than 30 cm and the horizontal dimension W is 32 cm, the dimensions of the front opening 12 tend to be too large compared to the full-face masks 20 of all manufacturers currently in production. As a result, when the boundary between the periphery 12a of the front opening 12 and the full-face mask 20 is sealed with a sealing material, unnatural wrinkles tend to form in the hood 11, reducing the wearer's ease of movement and comfort.

[0018] Furthermore, if the vertical dimension H of the front opening 12 is greater than 30 cm and the horizontal dimension W is greater than 32 cm, the dimensions of the front opening 12 tend to be too large compared to the full-face masks 20 of all manufacturers currently in production. As a result, when the boundary between the periphery 12a of the front opening 12 and the full-face mask 20 is sealed with a sealing material, unnatural wrinkles tend to form in the hood 11, reducing the wearer's ease of movement and comfort.

[0019] In addition, when the vertical dimension H of the front opening 12 is less than 30 cm and the horizontal dimension W is less than 32 cm, the dimensions of the front opening 12 are too small for all currently produced full-face masks 20 of all manufacturers. As a result, the peripheral edge 12a of the front opening 12 is too tightly clamped against the full-face mask 20, significantly reducing the wearer's ease of movement and comfort.

[0020] In addition, when the vertical dimension H of the front opening 12 is less than 30 cm and the horizontal dimension W is 32 cm, the dimensions of the front opening 12 tend to be too small for all currently produced full-face masks 20 of all manufacturers. As a result, when the boundary between the peripheral edge 12a of the front opening 12 and the full-face mask 20 is covered with a facing material, the peripheral edge 12a of the front opening 12 is too tightly clamped against the full-face mask 20, and the wearer's ease of movement and comfort tend to decline.

[0021] In addition, when the vertical dimension H of the front opening 12 is 30 cm and the horizontal dimension W is less than 32 cm, the dimensions of the front opening 12 tend to be too small for all currently produced full-face masks 20 of all manufacturers. As a result, when the boundary between the peripheral edge 12a of the front opening 12 and the full-face mask 20 is covered with a facing material, the peripheral edge 12a of the front opening 12 is too tightly clamped against the full-face mask 20, and the wearer's ease of movement and comfort tend to decline.

[0022] More specifically, if the dimensions of the front opening 12 are small relative to the full-face mask 20, the front opening 12 has to be forcibly widened to cover the hood 11, and since there is no slack in the hood 11, it becomes a factor causing a taut feeling. This taut feeling can prevent smooth movement when the wearer looks down or turns sideways, and can be a factor impairing workability and safety.

[0023] [Asbestos Working Method] An asbestos working method according to an embodiment is a method in which an operator wears a full-face mask 20 and protective clothing 10 to perform asbestos work. As shown in FIG. 4, this method includes a protective clothing wearing step S1, a mask wearing step S2, a glove / boot cover wearing step S3, and a facing step S4.

[0024] The protective suit wearing process S1 is the process of putting on the protective suit 10. The mask wearing process S2 is the process of putting on the full-face mask 20.

[0025] The protective suit wearing process S1 includes a protective suit temporary wearing process S1a, in which the wearer's limbs and torso are covered with the protective suit 10; a hood opening process S1b, in which the hood 11 is placed over the wearer's head; and a fastener closing process S1c, in which the fasteners 12 are closed. The hood opening process S1b and the fastener closing process S1c are performed after the mask wearing process S2. Here, the fastener closing process S1c includes a step of setting the slide fastener 13 to a half-closed state, that is, a step of moving the slider (not shown) to an intermediate position in its range of motion (for example, the position of the abdomen or chest), but at least the step of setting the slide fastener 13 to a fully closed state is performed after the mask wearing process S2.

[0026] In this way, after attaching the full-face mask 20 to the wearer's head, the hood 11 is placed over it, and the slide fastener 13 is fully closed, making it possible to cover the peripheral edge 21a of the front opening 12 of the hood 11 with the outer surface of the rear peripheral edge of the full-face mask 20 and make it fit snugly.

[0027] The glove and shoe cover wearing process S3 is the process of putting gloves 30 on the wearer's hands and putting shoe covers 40 on the shoes on both feet.

[0028] The sealing process S4 includes a mask sealing process S4a, in which the boundary between the peripheral edge 12a of the front opening 12 and the full-face mask 20 is sealed with sealing material; a fastener sealing process S4b, in which the fully closed slide fastener 13 is sealed with sealing material; a glove sealing process S4c, in which the boundary between the hem 14a of the sleeve 14 of the protective suit 10 and the glove 30 is sealed with sealing material; and a shoe cover sealing process S4d, in which the boundary between the hem 15a of the pants 15 of the protective suit 10 and the shoe cover 40 is sealed with sealing material.

[0029] By going through the above series of steps S1 to S4, the wearer can safely perform asbestos work with their entire body protected by the protective suit 10, full-face mask 20, gloves 30, and shoe covers 40.

[0030] According to this work method, by wearing a protective suit 10 with a front opening 12 having a vertical dimension H of 30 cm and a horizontal dimension W of 32 cm, the wearer's ease of movement and comfort while wearing the protective suit 10 together with the full-face mask 20 can be improved, and consequently, the work efficiency and safety of asbestos work can be improved.

[0031] It should be noted that the present invention is not limited to the embodiments described above. Those skilled in the art will see that various modifications and alterations can be conceived within the scope of the claims, and these will naturally fall within the technical scope of the present invention. Furthermore, the components of the embodiments described above may be combined in any way without departing from the spirit of the invention.

[0032] For example, although the above embodiment describes protective clothing equipped with a slide fastener, it may also be equipped with a hook-and-loop fastener instead of a slide fastener.

[0033] Furthermore, since protective clothing is manufactured using flexible fabrics, the dimensions and shapes of each part of the manufactured protective clothing (product) will not be exactly the same as the design dimensions in a strict sense. Therefore, even for the vertical dimension of the front opening of 30 cm and the horizontal dimension of 32 cm, there may actually be a variation of about ±0.2 cm between products. In other words, the protective clothing of the present invention includes not only protective clothing with a front opening of dimensions of 30 cm vertically and 32 cm horizontally, but also protective clothing with a front opening of dimensions of 30 ± 0.2 cm vertically and 32 ± 0.2 cm horizontally.

[0034] Furthermore, while the protective clothing of the present invention is intended to be worn with a full-face mask, it is of course possible to wear it with a half-face mask as well. [Explanation of symbols]
