Definitions
- the invention relates to an individual disposable suit for protection against radioactive particles.
- the invention finds application in industrial activity in a contaminated environment.
- contaminated is meant an environment in which are dispersed radioactive particles capable of coming into contact with the operating personnel in the installations.
- the individual disposable protective suit against radioactive particles is also called over-clothing.
- the current uniforms used on a fleet of power plants in operation of the fleet are used universally for all types of trades and environment. These mainly guarantee watertightness contamination during activities in a contaminated area. However, these over-clothes may prove to be insufficient during the undressing phase for example.
- underlying dress which can be in his first case his personal dress , called “blue” for work, or in a second case a so-called universal outfit imposed, such as for example a T-shirt, a pair of socks, a jumpsuit, a pair of cotton gloves, a cap and a helmet ), over-clothing, but also gloves made of vinyl or a thicker material such as rubber or other plasticized material and over-boots.
- the wearing of over-clothing is compulsory when the surface radioactive activity is between 0.4 and 400 Bq / cm 2 in the first case and between 4 and 400 Bq / cm 2 in the second case. Above 400 Bq / cm 2 , the operator must wear a ventilated helmet, for example a protection covering the whole of the head to the base of the neck, or even over his over-holding an outfit waterproof ventilated, for example a protection covering the whole body.
- a ventilated helmet for example a protection covering the whole of the head to the base of the neck, or even over his over-holding an outfit waterproof ventilated, for example a protection covering the whole body.
- the undressing phase linked to over-clothing is delicate.
- the operator while in a contaminated area, the operator must take off the outerwear, gloves and overboots without contaminating his own clothes - generally "work overalls" worn below-, in doing so, the operator must consecutively cross a border materialized for example by an easel, to pass into an uncontaminated area.
- this border crossing is not always easy for the operator and can lead to disadvantages. Indeed, the latter must pass a first leg undressed over-holding behind the easel without touching it and keeping the second leg still wearing the over-holding in the contaminated area. Then he must undress the second leg of the overgarment in the contaminated area, then cross the border and finally find himself in an uncontaminated area. These crossing conditions can cause loss of balance and cause the foot of the undressed leg to rest in a contaminated area. Once finally crossed this border successfully, the operator who is therefore likely to have been contaminated, will pass through the gates of checks as it is de rrequisite in all nuclear power plants in the world which, if necessary, will signal actual contamination. The operator will then follow the protocol in force following a detection of contamination whatever its origin. We can also cite in the margins the classic risks of accidents known as on the same level.
- a first drawback is the risk of risk of contamination in the case of unconventional undressing.
- the operator may find it advantageous to remove his overwear in the contaminated zone and then cross the border. To do this, he must first open his zipper from the neck to the crotch, then tear his over-crotch to the bottom of each leg which will give him comfort at shoulders and will prevent him from finding himself in almost unbalanced positions.
- This practice not recommended by the operator certainly saves him time, but the main drawback is that the contamination potentially deposited on the over-clothing during his intervention can then be resuspended in the air following the force given to the tearing and therefore induce contamination of the operator himself, his colleagues but also the premises.
- a second drawback is the risk of contamination by opening the overfit.
- operators are required to carry documents and portable devices such as a dosimeter must be visually accessible according to regulations.
- the operator can be led by necessity to open the overwear to access the information sought in said documents, or displayed by said devices.
- the operator runs the potential risk of direct contamination by his gloves.
- the current non-woven overwear includes at least one transparent plastic window intended to display the clothing underlying the location of the said control devices, badges or documents carried thereon.
- said plastic windows may lose their transparency in the short term, or even during the same operation due to friction, bending, etc. In these conditions, the information sought by the operator becomes less and less clear or visible, so that, to access it, the operator is obliged to open his over-clothing, which is in contradiction with the objectives of limiting the risk of contamination.
- the invention aims to obtain an individual disposable combination of protection against radioactive particles, which overcomes the above-mentioned drawbacks of overwear.

- the first junction point S2 connects, for example, the upper end tooth D31 of the strip BA31 to the upper end tooth D32 of the strip BA32.
- the tab LA Due to the fact that in the closed state, the closures FG1, FG2 and FG3, the tab LA is located inside the suit 1, the tab LA is not contaminated by radioactive particles. Pulling by the person wearing the combination 1 on the tab LA naturally opens the zippers FG2 and FG3 by simple separation of their respective bands BA21, BA22 and BA31, BA32 along their prescribed line of engagement LE2 and LE3.
- the person can then pull on the outer edges 311 and 322 of the legs 31 and 32 to finish the opening of the closures FG2 and FG3 along the lines LE2 and LE3 of engagement.
- the junction point is formed by a connecting part CO, for example provided on the outer surface of the suit 1 when the closures FG1, FG2 and FG3 are in the state closed.
- the connecting piece CO comprises a first junction flank J1 connecting the lower end BAI 10 on the first side BA11 to the lower end BA120 on the second side BA12, a second junction flank J2 connecting the upper end BA210 of the second strip BA21 at the upper end BA220 of the second strip BA22 and a third junction flank J3 connecting the upper end B A310 of the third strip BA31 to the upper end BA320 of the third strip BA32.
- the breaking LA member is formed by the cursor CU of the first zipper FG1.
- the breaking member LA is configured so that its descent on the connecting part CO makes it possible to break the first, second and third flanks J1, J2, J3 of junction.
- Operation is for example the following, illustrated with reference to FIGS. 6 to 9.
- the closures FG1, FG2 and FG3 are in the closed state and the cursor CU is located near the upper end of the latter.
- the operator moves the cursor CU in the direction of the arrow Fl down to change the closure Fl to F open state.
- the connecting CO part has a prescribed point of weakness, so that the CO part breaks above a stress threshold.
- the connecting part CO may for example, but not be limited to, an intrinsic connection in the close vicinity of the six bands BA11, BA12, BA21, BA22, BA31, BA32 of the three closures FG1, FG2 and FG3.
- the connecting piece CO can also be a fabric element, sewn or glued, capable of presenting a tear DE as soon as the effort threshold is exceeded.
- the connecting part CO is broken into a part CO connected on the one hand to the side BAI 1 and on the other hand to the strip BA21 and in another part CO 'connected on the one hand at the BA12 side and on the other hand at the strip BA32 and opens from the junction flanks J2 and J3 the closures FG2 and FG3 along their prescribed line LE2, LE3 of engagement, as represented by the arrows F4, F5, F6 and F7, which represent the separation of the two bands BA21, BA22 and BA31, B A32 from each of the closures FG2 and FG3.
- a fourth step in FIG. 9 the complete opening of the closures FG1, FG2 and FG3 is accomplished as represented by the arrows F8, F9, F10, Fi l, Fl 12, F13 and the operator can remove his combination 1 .
- This embodiment is intrinsically hermetic to contamination, since it does not offer an opening area requiring the fitting of an SP sub-bridge as for the first embodiment.
- the other closure FG2 and / or FG3 can also be a zipper of the first type comprising its own cursor (called another cursor) distinct from the cursor CU, to allow the band BA21 to be connected to each other.
- BA22 strip or BA31 strip to BA32 strip along the other LE2 or LE3 mesh line by moving this other cursor up and down along it and to allow the BA21 strip to be separated from the strip BA22 or the strip BA31 with respect to the strip BA32 along this other line LE2 or LE3 of meshing by displacement of this other cursor up and down along one of these strips.
- the two bands BA21 and BA22 of the other closure FG2 may be of the second type not carrying a cursor on the combination 1 as indicated above, to mesh with each other along the another LE2 line of meshing in the closed state, these two bands BA21 and BA22 being configured to be able to be separated from each other along the other LE2 line of meshing by traction on one and / or the other of the two bands BA21 and BA22, that is to say without having a cursor to be separated.
- the two bands BA31 and BA32 of the other closure FG3 can be of the second type not carrying a cursor on combination 1 as indicated above, to mesh with one another along the other line LE3 of meshing in the closed state, these two bands BA31 and BA32 being configured to be able to be separated from each other along the other line LE3 of meshing by traction on one and / or the 'other of the two bands BA31 and BA32, that is to say without having a cursor to be separated.
- the closure FG2 and / or FG3 of the second type may have been obtained by cutting a desired length L of a slider zipper in the closed state, this length L being located behind the cursor (for example made of plastic) of this zipper in the closed state in the closing direction S 10, as shown in FIG. 17.
- This length L has the bands BA21 and BA22 or BA31 and BA32 connected to each other by meshing their teeth along their LE1 or LE2 meshing line and does not carry the slider of this zipper in the closed state. This length L is kept to close it FG2 and / or FG3.
- the part 2 of the trunk ends upwards by a closed collar C situated beyond the upper end
- Collar C is dustproof and comprises a left front part C1 and a right front part C2, which is connected to the left front part Cl by a front closing band CF.
- This front closure strip CF is dustproof and is located higher than the upper end FG10 of the first zipper FG1.
- This band before closing CF prevents contaminated particles crossing the neck C and arriving in the neck of the person above the closure FG1.
- the FG1 zipper does not close up to the top of the neck C but up to the limit of the bottom of the neck C. This makes it easy to open the FG1 zipper without holding the neck.
- the neck C is thus of the crossover type with the front closing band CF forming a valve so as to protect the neck from external contamination and to cover the underlying holding.
- the legs PF1 and PF2 are used for manual gripping of the C-neck without inserting the fingers inside the C-neck, which avoids introducing contaminated particles into it.
- the organ OP for gripping the cursor CU of the first zipper FG1 can be extended by a part of fabric, for example of a color different from that of the other parts of closing FG1 and the wall 4. Operators can thus identify and catch the CU cursor more easily and avoid looking for it and then increase the risk of clothing and / or body contamination.
- This PD cursor CU extension must not be too short, as it must be able to be grasped with a hand wearing a cotton glove, or too long to avoid being caught during procedures.
- the combination 1 comprises lines LC1, LC2, LC3 of seam visible on the reverse side ENV of the wall 4 and invisible on the place END of the wall 4.
- These lines LC1, LC2, LC3 of seam are for example of a different color from that of the wall 4 or that of the reverse ENV of the wall 4. The person can thus better distinguish the reverse ENV and the place END of the combination 1.
- combination 1 is used only once. When undressing, once combination 1 has been removed, the operator throws it into a dedicated bin. During this phase, he must not contaminate his hands, in particular when he folds combination 1. Indeed, the reverse side ENV and the place END of combination 1 being most often white, it can confuse the 'reverse ENV devoid of contamination with the place END which may be contaminated.
- These seam lines guide the operator so as not to contaminate himself.
- the combination 1 comprises two sleeves M for passing the arms of the person.
- Each sleeve M has a second dust-tight wall 46 and is connected at the top of the part 2 of the trunk.
- Each sleeve has an edge BE of free end, which surrounds the opening OUV of end allowing the passage at least of the index, middle finger, ring finger and little finger of the hand of the person.
- Each sleeve M has at least one TPP hole for the thumb of the person's hand to pass through. This thumb passage TPP hole is distinct from the opening OUV and is separated from the end edge BE by an end part 47 of the second wall 46.
- the operators can wear cotton gloves, sometimes superimposed on vinyl or other depending on the type of intervention. It was then that they put on combination 1.
- TPP thumb hole for the passage of the thumb integrated into the over-hold 1 makes it possible to remedy this problem.
- This TPP thumb hole can have the form of a slit at the end of the sleeve M.
- This TPP thumb hole can be indicated on its periphery by a different color from that of the rest of the second wall 46 of the sleeve M, which signals its position.
- This TPP thumb hole is also called a thumb hole.
- the size T of the combination 1 comprises an inner sheath FT peripheral in which is disposed an elastic EL for peripheral clamping.
- operators have the habit of choosing a combination size 1 greater than that which would correspond to them, in order to have more space, ease and comfort inside the overgarment. , especially during sustained physical efforts.
- there is a bouffant effect which comes mainly from an elastic sewn within the over-all around the waist. This bouffant effect is conducive to snagging or tearing of the over-holding, which can then contaminate the operator.
- This embodiment makes it possible to solve this problem by making it possible to insert into the back of combination 1 the more flexible EL elastic in the FT sheath, this EL elastic not being sewn to combination 1 so as to no longer have to bouffant effect.
- the combination 1 includes reinforcements RG at the knees G of the pants part 3. This avoids tears in combination 1 and thus prevents contamination.
- These RG reinforcements have, for example, a height and a width greater than those of the person's knees, in order to be able to suit all body types.
- the combination 1 comprises a transparent outer wall 43 located to the left of the first FG1 zipper at the front in the trunk part 2 and / or a transparent outer wall to the right of the first FG1 zipper at the front in part 2 of the trunk.
- This wall 43 and / or 44 forms an external transparent window.
- This wall 43 and / or 44 located on the place END of the combination 1 respectively forms a pocket PCH1 left and / or a pocket PCH2 right with respectively another underlying wall 43b left, located on the reverse side ENV and / or with another underlying right wall 44b, located on the reverse side ENV.
- the wall 43b and / or 44b can be transparent or opaque.
- the left PCH1 pocket and / or the right PCH2 pocket has a width greater than or equal to 15 cm and a height greater than or equal to 15 cm.
- the transparent outer wall 43 and / or 44 allows the person to see from the outside the objects located in his pocket PCH1 and / or PCH2 and thus to be able to view in real time the digital value of the dose displayed by a dosimeter present in this pocket. It is imperative that the operator has permanent access to the dosimetry reading on his own dosimeter, so that he does not exceed his forecast dose or in some cases the regulatory limits. This prevents the operator from having to open his combination 1 in order to read this dosimetry and thus prevents him from becoming contaminated.
- the wall 43 and / or 44 thus forms a transparent window at chest level.
- This wall 43 and / or 44 and / or 43b and / or 44b may be made of an acetate type material, which has the property of remaining transparent when folded, or the like.
- the size of the window has been studied so that the PCH4 dosimeter pocket is always visible even in cases where it moves during physical efforts, this PCH4 dosimeter pocket itself being formed from transparent walls and having been inserted in the PCH1 or PCH2 pocket.
- the PCH1 and / or PCH2 pockets can be of the wallet window type.
- the other wall 43b and / or 44b may be made of the same material as the wall 4, which is not transparent.
- the PCH1 and / or PCH2 pocket has an opening located in its upper part between its wall 43 and / or 44 and its wall 43b and / or 44b.
- the underlying wall 43b and / or 44b is made of a dustproof material.
- the combination 1 comprises a removable ventral PCH5 pocket, having a transparent outer wall 45.
- This PCH5 pocket is located at chest level and can contain A4-type documents and / or small equipment.
- the wall 45 can be made of acetate for example.
- the underlying wall of the PCH5 pouch can also be made of a transparent material or of a non-transparent material.
- the PCH5 pocket has an upper part with a fourth FG4 zipper and AT attachments configured to be able to be connected and disconnected with respect to a corresponding upper front part of part 2 of the trunk. These AT attachments are for example of the clip type.
- the PCH5 pouch can also include fasteners in its lower part, these fasteners can be, for example, snaps.
