g)
Warning:
The helmet is intended for use in an atmosphere that does not represent an imminent
danger to human life or health and contains at least 19.5 % by volume oxygen. The operator
should be able to escape from this atmosphere without needing to use the helmet.
The Apollo 100CE blast helmet will not provide adequate protection in certain highly toxic
atmospheres caused by e.g. lead-contaminated dust that results from removing lead-containing
paints or other paints, asbestos, heavy metals etc. In such cases, there may be a risk to human
life and health.
Lead poisoning may cause death. The maximum workplace concentration has been defined as
0.1 mg/m³ of air (TRGS 900). For this reason, the blasting contractor must always determine
which type of paint is to be removed and, if necessary, ensure that operators wear a blast hood
or helmet that is approved for use with these substances or an additional respirator. In
accordance with DGUV Regulation 112-190, Class 4B blast protection equipment can be used at
up to 500 times the threshold value.
h)
Warning:
During a period of very high use, peak respiration may produce negative pressure in the
helmet.
i)
Warning:
The air supply must comply with EN 12021.
j)
Warning:
The moisture content in the breathing air must be kept within the limits specified in EN
12021 to prevent the supplied air respirator with continuous air flow from freezing. If the
equipment is used at a temperature below 4°C, the moisture content must be limited to prevent
freezing.
k)
Warning:
The equipment must not be operated with pure oxygen or oxygen-enriched air.
l)
Warning:
Each operator connected to the air supply system must check that the capacity of the
system is adequate as described in the information provided by Clemco.
m) It is imperative that operators follow the instructions for donning the equipment as provided by
Clemco. These are contained in Sections 4 (Preparation) and 6 (Operation) of this owner's
manual.
n) The air supply line is not resistant to contact with hot surfaces or boiling water and is therefore
not labelled accordingly.
o) The air supply line is not antistatic and is therefore not labelled accordingly.
p) Do not use aggressive chemicals or solvents to clean the equipment. This may irritate or harm
the operator and alter the properties of the material used. Please also consult the instructions
concerning cleaning products and disinfectants in Section 9 of this owner’s manual.
q) No assistance is required when using the respirator because the operator will be warned if the air
supply falls to inadequate levels by the flag of the air indicator dropping in his field of vision. If the
operator is wearing ear protection or soundproofed communications equipment, there is therefore
no need for any further measures to be taken.
r)
Warning:
Particular attention must be paid to ensuring that the apparatus is not accidentally
connected to other gas supplies, e.g. oxygen, acetylene or nitrogen. Never connect the breathing
air line to an air source that has not been tested for gas or particulate contamination.
