who has extensive knowledge of the NOVA.
Before using this helmet ensure your employer has determined that airborne contaminant concentrations
do not exceed those allowed by Government regulations and recommendations for a compressed air line
breathing helmet. It is required that the employer measures and monitors airborne contaminant levels
intheworkarea.TheNOVAisnotdesignedforuseinammableatmospheres.
DO NOT WEAR this helmet if any of the following conditions exist:
- Atmosphere is immediately dangerous to your life or health
- You CAN NOT escape without the aid of the helmet
- Atmosphere contains less than 19.5% oxygen
- Work area is poorly ventilated
- Contaminants are in excess of regulations or recommendations
- Radiation exists in the work area, or materials are Radioactive
Do not modify or alter this helmet. Usa only approved NOVA components and replacement parts. The use
of non approved parts voids the EN 271 approval of the entire helmet assembly.
Inspect all components of the helmet daily for signs of damage or wear and tear that may reduce the
level of protection originally provided.
Do not use abrasives containing silica, lead, arsenic or sharp glass particles - use of abrasives containing
these elements could result in serious injury or death.

BE CERTAIN your employer has determined that the breathing air source provides at least EN 12021
breathableair.Thehelmetmustbesuppliedwithcleanlteredbreathingairatalltimes.
DO NOT connect the helmet’s air supply hoge to nitrogen, toxic gases, inert gases, oxygen, oxygen en-
riched or ether unbreathable non EN 12021 air sources. Check the air source before using the helmet.
This helmet is not designed for use with mobile air supply systems i.e. cylinders. Failure to connect the
supply hoge to the proper air source could result in serieus injury or death.

DO NOT wear this helmet if the ambient usage temperature is below -10°C or above +60°C. Moisture
content of breathable air should be controlled when the helmet is to be used in temperatures below 4°C
to avoid freezing the helmet.
