Donning the SE400
The user must be familiar with and practise the donning and doffing procedures prior to
respirator use.
Warning
Men should be clean-shaven, and should not have facial hair such as beards or large
sideburns. Facial hair can seriously compromise the face seal and result in reduced
protection.
Note:
Before donning a respirator for the first time, perform a facepiece fit test per section
Facepiece Fitting
(applies to full facepieces only)
.
SEA recommends that each new (unused)
respirator be tested for facepiece fit even if the user is experienced with the respirator.
Note:
Users who have been approved to use the SE400 only with Full Face Mask Insert (SEA-
FI) should check that the insert is correctly fitted and is in good condition prior to donning.
Note:
Before first use and after maintenance, perform a respirator “Self-Test”. Refer section
Operation.
Note:
Users should be well hydrated before donning and using the respirator.
Note
: When donning the SE400 with an SE-shield protective suit, consult the SE-shield user
instructions.
Procedure:
1. Visually inspect the respirator for completeness, correct assembly and lack of
damage
2. Put the facepiece neck strap over your neck
3. Put on the fan unit (with back pack or waist belt) and adjust the straps
4. Fully loosen the head harness straps
5. Clear all hair away from your face. A thin elasticised head band may be used,
provided it is kept clear of the face seal
