RT-Series Hood Donning Procedures
1. Locate and connect the unattached
end of the nylon strap with Velcro
to the opposite side of the hood.
This provides the overall shape of
the hood and lens.
2. Pull the hood over your head so the
lens is directly in front of your face.
3. Tuck inner bib of hood into shirt or
protective clothing.
4. Pull outer bib over collar of shirt or
protective clothing.
5. Ensure the neck cuff is below the
chin and in a comfortable position.
6. Bring Velcro straps located on rear
outer bib on either side of the bib,
to the front of your body and attach
to front outer bib.
LF-Series / RT-Series Useability Guidance
• Special consideration should be taken for users with long hair in a
ponytail-style to ensure the hood remains secure on the head. Ponytails
should be worn low at the nape of the neck (below the occipital lobe) and
the knot tucked into the rear of the LF-Series hood as required to ensure a
comfortable and stable fit.
• User’s build should be taken into consideration if the worker is required to
perform duties that require them to crawl or to be in smaller-than-normal
spaces. Verify that the equipment does not interfere with the working
environment. Select the appropriate belt or backpack for the application.
If the belt or backpack need to be worn in alternate positions, verify the
breathing tube is the correct length (an alternate breathing tube length
and belt or backpack combination may be required).
