Applicable standards, field of application, cautions and warnings

The goal of the C 700 series mask is the breathing protection of a subject who is in an environment with not breathable air. The specific function of the mask is to isolate the user’s breathing apparatus from the not breathable air coming from the external environment.
C 700 masks are PPE belonging to the III category according to the European Regulation (UE) 425/2016, and they conform to the requirements specified in the with EN 136:98 Norm, in class 3, for special use. The model C 701 and C 702 are equipped rispectively with standard threaded according to the Norm EN 148-1 and two threaded  connectors (complete with gasket and inhalation valve) for use with two SEKUR filters of the 200 series. Masks are not suitable for use in potentially explosive atmospheres. For need of use in these conditions can contact D.P.I. s.r.l.
Testing according to the relevant Norms, certification and authorisation to CE marking have been performed by the Notified body Italcert – Viale Sarca, 336 – 20126 Milano.
The marking CE on the visor frame of the masks “CE 0426“ indicates the respect of the Essential Health and Safety Requirements defined in 425/2016 Regulation following the Annex VIII and identifies the Notified body carrying out the production – Italcert – Viale Sarca, 336 – 20126 Milano – Italia (Organismo Notificato n. 0426).
C 700 masks visors conform to the STANAG2920 (ed. 3):2015 Measurament of V50 (Ballistic test, FSP= caliber 22 type 1) and to the EN 166:2001 Personal eye- protection -§7.1.2.1 “Spherical, astigmatic and prismatic refractive powers” achieving optical class I.
The instructions for use of filters and respiratory equipment, as well as the safety standards and regulations issued by the competent authority, must be strictly followed. Respiratory protective devices must be used by personnel in good health and trained in the use of this kind of equipment. Users must be beardless and without sideboards
or moustaches as these interfere with the facepiece seal, thus impeding adequate seal tightness on the face. The users of C 700 masks must ensure that the oxygen quantity higher than 18%, range of temperature between 0°C and 50°C and the highest concentrations of contaminants in the atmosphere are not exceeded. The permissible exposure limits are indicated in the manual containing the instructions for use of filters and self-contained breathing apparatuses used with the mask. In case of contact with lubricants and oil by- products, solvents, oxidizing agents, acetates, hydrogen peroxide, acids and strong bases, wash and clean the mask afterwards as soon as possible in accordance with paragraph 7.2.
The EN 136 defines maximum limits of penetration for a full face mask that, if the donning is correct and it is used respecting all the warning and limitations described in this manual, satisfying the “total inward leakage” requirement, assures a maximum penetration value of 0,05% whom has to be added the penetration through the filtering device.
Following the Nominal Protection Factor (NPF), defined as 100 divided by the total inward leakage maximum percentage allowed, the mask assures an NFP equal to 2000.
On the basis of the Internal Regulation, with respect to the III category of the PPE, the use of the C 700 masks requires prior training.

2.1. Specific usage
When the hazards potentially present in the workplace call for respiratory system protection and use of protective equipment, the compatibility of these devices with the mask must be carefully tested. These additional protection measures must not jeopardize the full effectiveness of the respiratory protective equipment.
The hazards potentially present in the workplace can be the following:
− Liquid or gaseous substances which are harmful in contact with skin
− Toxic substances which are irritating to skin
− Radiations
− Mechanical stress
− Explosions in the atmosphere
− Oxygen-enriched atmosphere
D.P.I. s.r.l. technical services are at your disposal for any assistance, explanation, advice or information you might need.

Operating principles

The air inhaled through the inhalation valve in the connecting piece is fed into the mask and flows in the inner side of the visor thus preventing misting. The air enters the inner mask through the septa of the halfmask and after use by operator, is exhaled through the exhalation valve.

Mask components

C 700 masks are made up by the components represented and indicated in the figure 1 , figure 2, figure 8, figure 9 and figure 10.

Donning and tightness test

C700 series masks are available in medium size which fits well most faces.
For the wearing with the rubber harness, follow the instruction below:
6.1 Using the head harness buckle seat adjustment, loosen the five harness buckle
6.2 Unfold the two buckle of the neck harness
6.3 Place the mask in front of the face holding it by the neck harness. Rest the chin in the special hollow of the mask and pass the harness over the head
6.4 Check that the pentagonal area where the arms of the harness meet is positioned in the nape of the neck. If it is too far away, lengthen the front buckle (or shorten it if it is too low) and adapt the tension of the other harness arms to the new position.
6.5 Then, pull the harness buckle in this order “Nucal”, “Temporal” and “Frontal”. The neck and temporal straps of the harness should be adjusted in pairs and with two hands if possible. Finally, pull the front harness. The harness should be adjusted in such a way that a uniform pressure from the sealing edge of the mask is felt on the face.
6.6 After putting on the mask and before use, carry out a leak test. Close the mouthpiece with the palm of your hand and inhale so that the mask adheres to the face. There should be no noticeable air infiltration anywhere on the mask. The leak test must be repeated 2-3 times. The mask can only be used after passing the leak test.
6.7 To remove the mask, loosen the harnesses in the same order used in the donning procedure. Push the buckles forward with your thumb. Remove the mask from the chin and then remove it from the head.
Warning: if the tightness test described in paragraph 6.6 is not passed, repeat it until the tightness is achieved.
The use of the mask that does not have a sufficient seal can cause serious damage to the user’s health.

Maintenance, cleaning and disinfection

In order to maintain efficient C 700 masks, periodic maintenance, cleaning and disinfection is need, following the table below.
7.1. Checks and periodic maintenance
The user must ensure that periodic maintenance checks are carried out on the respiratory protection device as defined in the instruction manual provided by the manufacturer.

Legenda:

1. Even in absence of use, unless it has been stored in airtight package.
2. Only if exposed to heat sources
3. The test consists in checking that are not noticed leakages through the mask after donning it, closing the inhalation inlet with the palm of the hand and building a negative pressure by attempting to inhale.

7.2. Cleaning
The mask must be cleaned every time it is used. Lack of cleaning, besides hygienic problems, can also jeopardize the correct functioning of the device. Washing can be performed in a traditional way by dipping in water, or by ultrasonic washing. In both cases, depending on the need to perform a deep cleaning of the mask due to its conditions, it can be disassembled and all the components can be cleaned separately.
Il lavaggio a ultrasuoni deve essere svolto con macchinari SONOREX SUPER RK514BH o RK1028CH che possono essere forniti dalla D.P.I. s.r.l.. L’utilizzo di macchinari diversi può pregiudicare il funzionamento della maschera.
Ultrasonic washing has to be done with SONOREX SUPER RK514BH equipment or RK1028CH which can be supplied by D.P.I. s.r.l.. Using different equipment can damage the correct functioning of the masks. Ultrasonic washing temperature must be set at a temperature not higher than 40°C using a mild detergent 5% dilution in water.
Traditional washing can be performed with tepid water and a mild detergent 5% dilution in water. In any case, never use solvents! After cleaning it thoroughly, rinse under running water and hung up to dry in open air, avoid in any case exposure to direct solar radiation, or in special cupboards. During drying pay attention not to expose the mask to direct contact with hot parts or with hot air (warmer than 45°C) or to direct solar radiation in order to avoid damages to rubber parts. Check that after cleaning operations no traces of detergent are left otherwise repeat rinsing and drying. If the mask has been disassembled for washing, a leak tightness test with test equipment has to be performed. If the mask has been exposed to chemicals particularly toxic, biological or radioactive agents, maintenance has to be performed by specialized personnel or by D.P.I. s.r.l. Maintenance and Assistance Service.

7.3. Disinfection
Mask disinfection is necessary when it is worn by different users in order to prevent hygienic or sanitary problems.
Disinfection can be performed in a container after cleaning or can be performed by the equipment SONOREX SUPER RK514BH or RK1028CH which can be supplied by D.P.I. s.r.l.. Keep in mind that detergent and disinfecting agent neutralize each other when used at the same time, therefore baths have to be kept separate washing carefully the container among the two. Disinfection can be performed only with authorized detergent 5% diluted in water. At the end rinse in running water and dry with the same precautions as of paragraph 7.2 Warning: for the cleaning and disinfection don’t use solvents (like acetone and alcohol) or abrasive substances.
Follow only the procedure described in the two previous points and use only the indicated detergent and disinfectants. Detergents, dosages and exposure times other than those indicated, could damage the mask.
The detergents not diluted can cause damages to the user’s health. Then using with care wearing glasses and gloves.

Tightness test with test equipment

In the event the mask has been disassembled in order to be cleaned or to have some component parts replaced, a tightness test must be carried out. Before carrying out the tightness test, make a visual check. Check valves, housing and rubber gasket in particular, in order to make sure they are clean. Defective parts must be replaced.
Mask which failed the tightness test cannot be used.
8.1. Test rig
The test equipment consists of an inflatable dummy head, a mouthpiece connector, a test rig, a plug to seal the exhalation valve and a plug to seal the threaded connector. The test equipment, allows for a negative or positive pressure test.
8.2. Testing
Place the mask to be tested onto the inflatable head (wetting the surface with water) and tighten the head harness.
Inflate until the head becomes stable and in good contact around the sealing edge of the mask. If necessary, adjust better the head harness. Place the sealing plug on the inlet threaded connector of the mask. Follow the test equipment instructions as shown in its instruction manual.
8.3. Leak tightness of mask and exhalation valves
The mask and exhalation valves pass the tightness test when, with the exhalation valve previously damped, after a 10 mbar (1000 Pa) negative pressure is created inside the mask, the pressure change is not more than 1 mbar (100 Pa) per minute. If the test is positive, remove the mask from the dummy head and dry it if necessary. The mask can be used only after passing the tightness test.

Transport, storage and disposal

The masks must be stored in place at a temperature not higher than 50°C, protected from cold and humidity, the rays of sun, intense heat, corrosive substances which can damage its rubber, shocks, risk of falling down, dust and dirt. The thermoplastic parts must not be submitted to prolonged tensions and pressures to avoid distortion. The masks must be stored in their cases or in special cupboards.
The C700 masks have not to be considered special waste and fall in to the code CER150203 and have to be disposed taking into account that their main component materials are:
– Rubber and silicon;
– Plastics;
– metal (low quantity).
Particular precautions in compliance with the provisions of the law must be adopted according to their possible level of contamination, based on their conditions of use, at the time of disposal as in this case they fall within the CER150202 code.
For transport, use the original packaging.

Specific maintenance instructions and replacement of spare parts

When the mask is disassembled in order to be cleaned and disinfected, it has to be reassembled following the same procedure of spare parts replacement unless differently indicated. Make sure that all component parts are correctly assembled, paying attention to not damage all component parts during these operations.
