Dimensions
Size based on body measurements taken while wearing a layer of underwear and without wearing shoes.
This chart is a guide for PPE garment selection. Proper fit varies with individual body shape and under clothing. Test garment for proper fit before use, as garment protection depends on selecting appropriate size.
Packaging & Labelling
Individual packing, 25 per box
Keep the coveralls in the boxes in order to protect the garment.
Instructions for use
Wearing the overall is mandatory:
- For medical and non-medical staff working in the high-risk zone of a VHF treatment unit
- For burial team in charge of preparation, transport and burial of corpses of people died of VHF and when carrying out disinfection of the morgue
- For ambulance team when transporting patients of VHF and carrying out disinfection of the ambulance
- For mobile team in charge of house disinfection
- For waste management staff when handling or disposing of VHF contaminated waste
- For all persons (staff and patients' attendants) in close contact with a patient with suspected or known VHF or SARS. Not suitable for family and visitors
Note:
The overall is part of the full personal protective equipment worn in VHF contexts (see the protective equipment module of the VHF kit).
Precautions for Use
- Wearers must receive appropriate training to advise why personal protective equipment is needed and its limitation, and when and how it is to be used
- Replace the overall if damaged
- When removing the overall follow the undressing protocol carefully
- Once it has been removed, it should be disposed of according to waste management rules
- Strictly for single use
Storage
Tychem® garments may be used for at least 14 years after receipt by the end user as long as all of the following conditions are met:
- The garment has been stored properly
- The garment has not been damaged, altered or contaminated
- The garment passes a full visual inspection
In case that the products have not been stored properly, please consult your supply center. (Examination of a sample by the manufacturer is a possibility)
Storage Conditions
- Store Tychem® garments in a cool, dark, dry location free of dirt and insects.
- Sunlight, ozone, high temperatures (>120 °F [49 °C]), exhaust fumes, compression under heavy weight and/or sharp protrusions are some conditions known to degrade or damage the materials in these suits.
- Store Tychem® garments such that they will not be stepped on nor have heavy objects placed on top of them.
MSF requirements
Indispensable item for the protection of staff and patients' attendants against blood-borne pathogens in haemorrhagic fever contexts.
The overall provides very high level of protection against the penetration of liquids and micro-organisms, excellent mechanical properties, including tear and abrasion resistance, outstanding softness to prevent skin irritations, ease of movements and comfort.
The protective clothing should ensure wearer comfort as well as protection.
