User Manual for Full Face Mask

  1. Prior to first use it is necessary to properly disinfect the mask at a minimum in 70% ethanol or other suitable disinfectant (recommended disinfection methods listed below).
  2. The mask is supplied assembled for disinfection, but it should be taken apart before first use – see details on dismantling the filter.
  3. After thorough disinfection, attach the mask to your face, with snorkel pointed upward and thoroughly secure the elastic at the top of the head. Make sure that you can breathe freely with the mask on your face and that you feel a good seal.
  4. After use, disinfect all parts of the mask and store them in a clean and dry place.

The mask includes an exhalation valve, so if you are infectious, the mask does not protect your surroundings. To eliminate this risk, place a mask or filter across the exhalation valve.

All necessary instructions that will be required along with the product itself, most will be supplied as simple package inserts.

 

Working Draft Document

Not an approved medical device

Declaration

The full face mask as presented is the result of the work of volunteer community groups Paladin Collaboration and is funded with support from numerous role players. The project derives technical support from Science and a number of doctors who have conducted testing on the mask.

This mask should be seen as a prototype of non-certified personal protective equipment for working under difficult conditions, where traditional PPE devices are no longer available. 

The mask is not provided with any additional support or warranty.

USE AT YOUR OWN RISK

Information for use

  • SHAVING: If you have a beard, shave along the line of contact where the mask facepiece meets your face. Facial hair can cause leakage and subsequent contamination of the inside of the mask.
  • FILTER LONGEVITY. Filter life is determined by its permeability. As prescribed by the manufacturer.
  • The Mask does not protect your surroundings. The mask includes an exhalation valve, so if you are infectious, the mask does not protect your surroundings. To eliminate this risk from exhalation, wear a filter or additional mask over the mask exhalation valve (inserted inside or possibly mounted outside the mask).
  • FOGGED-UP MASKS. Masks for long-term use can use a spray inside. This is not an obstacle to its functionality. To avoid condensation, it is possible to use a soap to polish the inner side of Plexiglas. 
  • MASKS AND VALVE TIGHTNESS. It is important to always check before use that there is no dirt in the membrane between the valve body and mask that would allow the entry of air into the exhalation valve. It is always necessary to check the mask visually before use. After putting mask on, check for clogging by placing your palm over the inlet filter and breathe. It should not allow air to enter through here. Masks should sit firmly on your face. Masks are available in two sizes (S / M and L / XL).
  • ACCUMULATION OF CO2. The mask is originally designed for snorkelling and intended for sports use and is not designed for long-term use on land. In addition, the filter has been modified to make temporary protective equipment. This is related to the greater accumulation of CO2 at the level of 1.5-1.7% by volume (for long-term use the concentration must not exceed 1% by volume). For your safety, therefore, take a break from work and, if clinically permissible, remove the mask briefly after 45 minutes. Every 5-10 minutes inhale and exhale deeply through the mask to promote better flow of air. If you feel unwell in the mask, feel dizzy or inadequately tired, the mask should be removed to provide clean air.
  • OTHER PROTECTIVE EQUIPMENT. Do not use other masks or disposable headgear inside the scuba mask. These devices can cause the mask to leak or increase retention of CO2. Where needed, place on additional gear OUTSIDE the mask (this refers mainly to single-use disposable headgear).

SUGGESTIONS TO DESINFECT

Suitable types of disinfectant

  • ETHANOL disinfection with Ethanol 70%  EtOH significantly reduces the risk of infection.
  • Sodium hypochlorite Sodium hypochlorite NaClO is used in solution as chlorine bleach (SAVO), and is often used for disinfection. Sodium hypochlorite can be diluted to a concentration of 1:10, and spray applied.
  • HYDROGEN PEROXIDE Disinfection with hydrogen peroxide significantly reduces the risk of infection. This approach is scientifically proven for use on 3D-printed components.
  • UVC For the disinfection of surfaces is required 186 mJ/cm2 to remove a substantial amount of viral pathogens.
  • PRESATURATED handkerchief Optionally, for disinfection it is also possible to use presaturated handkerchiefs, e.g. from Kimtech, which are impregnated with IPA.

Application of disinfectant

  • Mask: it is possible to insert mask in the bath for at least 30 seconds to disinfect.
  • It seems best to the application from the sprayer.
  • Pay special attention to disinfecting of rougher surfaces – ie silicone cheek and filter adapter.
  • Let the disinfectant freely spread across the surface. To minimize the risk of contamination, avoid wiping.
  • In case of disinfecting a larger surface you can use spray-on peroxide.
  • When applying disinfectant, carefully ensure sufficient ventilation space.

Removing Adapter

Remove the adapter only if it is damaged or needs to be replaced. When cleaning, simply unscrew the filter masks, as shown below.

Fitment

The Pano-View M2098G Snorkel mask comes in two sizes:

S/M and L/XL – Determine the mask that will fit you best using the below sizing guide.

The fitment is essential
A vacuum test is also a very reliable way of knowing that the mask is fitting correctly. Vacuum tests for each mask are explained below:

Version 1: Place the mask overhead and simply block the filter at the top of the mask. When you inhale you will feel the mask create a vacuum on your face. If no air is leaking into the mask and releasing the vacuum – you have a seal.
Try smiling and/or rotating your jaw to see if the movement of facial muscle breaks the seal.

Version 2: Place the mask overhead and simply block BOTH the filter at the top of the mask and the one near your mouth. When you inhale you will feel the mask create a vacuum on your face. If no air is leaking into the mask and releasing the vacuum – you have a seal.
Try smiling and/or rotating your jaw see if the movement of facial muscle breaks the seal.
