 Model 700 PAPR suits are designed 

for use together with Sundström SR500 and SR500 EX powered air 

purifying respirators (PAPR) conforming to EN 12941.

Fan Unit & Filters

Prior to use, it is important to read and understand the user instructions 

for the fan unit and filters.

Breathing Hose

The breathing hose is not included with your suit but is supplied 

separately by the respiratory device manufacturer. For assistance contact 

your respiratory device manufacturer or the MICROGARD technical team.

Operating Times

The operating times of the fan unit may vary. Please refer to the user 

instructions provided with the fan unit for information. 

Typical Areas of Use 

MICROGARD

®

 and MICROCHEM

®

 PAPR suits are designed to protect 

workers from hazardous substances. They are typically used for 

protection against direct jets of liquid chemicals (Type 3), saturation of 

liquids (Type 4) and particulate protection (Type 5) dependant on the 

toxicity and exposure conditions. The fabric has also been proven to 

provide a barrier to infective agents (EN 14126). The coverall has been 

tested according to EN 1073-2 for non-ventilated protective clothing 

against particulate radioactive contamination, however the product 

does not protect from radioactive radiation. The suits are supplied 

separately to the fan units and breathing hose. Prior to use the suit 

should be connected to a fan unit with filters in accordance with these 

instructions. The positive pressure generated in the head-top prevents 

particles and other pollutants from entering the breathing zone. 
If you feel uncertain about the selection, care and use of this equipment 

please consult your work supervisor or your sales outlet. Alternatively, 

please feel free to contact the Technical Department of MICROGARD Ltd.

2. Warnings and Limitations

Warnings

•  The suits are designed as single use and should not be re-used
•  Prior to use

-  Visually inspect the suit for any damage that may impair correct 

operation; pay particular attention to the seam areas

-  Ensure the PAPR fan unit is securely attached and operating 

according to the manufacturer instructions. 

-  Make sure the breathing hose runs along your back and is not twisted

-  Check the exhalation valves on the suit. If the valve diaphragm is 

damaged or distorted in any way it must be replaced

-  Check that vision through the visor is not obscured by excessive or 

large scratches or marks

-  Filters should be correctly fitted to the fan unit and not directly to 

the suit without the fan unit.

• The equipment must not be used: 

- If the suit, fan unit or filters are damaged in any way

-  If the fan unit is not running. In this abnormal situation, the 

equipment will offer no respiratory protection. In addition there is a 

risk of carbon dioxide quickly accumulating in the head top, which 

would lead to oxygen deficiency

- If the surrounding air does not have a normal oxygen content

- If the pollutants/hazards are unknown

-  In environments that are immediately dangerous to life and health (IDLH)

- With oxygen or oxygen enriched air

- If you find it difficult to breathe

- If you can smell or taste the pollutants

- If you experience dizziness, nausea or other discomfort
•  The wearing of chemical protective clothing may cause heat 

stress if appropriate consideration is not given to the workplace 

environment and performance of the protective clothing in terms 

of comfort ratings. 

•  Appropriate undergarments should be considered to minimise heat 

stress and prevent damage to the suit.

•  Care should be taken when removing a contaminated suit, so as 

not to contaminate the wearer with any hazardous substances. If 

the suit is contaminated then decontamination procedures should be 

followed (i.e. decontamination shower) prior to removal. Always leave 

the contaminated area before removing the equipment.

Limitations 

•  The determination of suitability of MICROGARD products for an 

application is the final responsibility of the user. All MICROGARD 

products are intended for single use. Upon contamination, wear or 

damage the garment should be removed and appropriately disposed of. 

•  If the user is exposed to very high work intensity, partial vacuum may 

occur during the inhalation phase or bending and squatting, which 

may involve the risk of leakage into the head top

•  The protection factor may be reduced if the equipment is used in 

environments where high wind speeds occur

• Never lift of carry the equipment by the breathing hose
•  Where the suit is to be worn with other PPE, and for full “Type” 

protection, it is necessary to apply additional adhesive tape at the suit 

interfaces. Gloves should be taped to cuffs and the storm flap should 

also be taped, whilst ensuring there are no gaps or creases. The 

user shall be the sole judge for the correct combination of suit and 

additional PPE. 

•  The coverall has been tested according to EN 1073-2 for non-

ventilated protective clothing against particulate radioactive 

contamination, however the product does not protect from 

radioactive radiation. 

•  MICROGARD

®  

and MICROCHEM

®

 PAPR coveralls are not 

intended to be used in applications where protection from gases/

vapours is required. 

Where resistance to gases/vapours and/or increased mechanical 

strength is required then ensembles which are certified according 

to EN 943-1 should be considered.

• In accordance with EN 1149-5: 2008;

-   Appropriate steps should be taken to ensure the wearer of suit is  

  properly earthed. The resistance between the person and the earth  

  shall be less than 10

8

Ω

, e.g. by wearing adequate footwear.

-    Electrostatic dissipative protective clothing shall not be opened 

or removed whilst in presence of flammable or explosive 

atmospheres or while handling flammable or explosive 

substances.

-   Electrostatic dissipative protective clothing shall not be used in  

  oxygen enriched atmospheres without prior approval of the  

  responsible safety engineer.

-   The electrostatic dissipative performance of protective clothing can  

  be affected by wear and tear, laundering and possible    

  contamination.
