2. Safety instructions

Non-observance of the safety instructions may have dangerous
consequences for the staff, the environment and the system and
may result in the loss of any claims for damages.
Should you require further information, please contact Grundfos.
Observe the separate supplier documents for the
Caution
components. All supplier documents are part of the
documentation package delivered with the system.

2.1 Working with chemicals

Warning
Danger of personal injury due to contact with
chemicals!
Wear the stipulated personal protective equipment
(protective clothing, gloves, goggles, etc.) when
handling chemicals!
Observe the chemical manufacturer's safety data
sheets (MSDS) and safety instructions of the used
chemicals!
Warning
Danger of personal injury due to contact with
chemicals!
If the system is installed in a confined room,
ventilation is required.
Spillages must be removed immediately.
The floor around the system must be slip-resistant.
Make sure, that parts in contact with the chemicals
are resistant to the chemicals under the specific
operating conditions!
Caution
Should you have questions regarding the material
resistance of the system for specific chemicals,
please contact Grundfos.

2.1.1 Personal protective equipment

Due to the variety of hazardous chemicals, any information
provided in this section is only general. It is the duty of the user to
ensure that he has obtained information on all safety precautions
relevant to the type of task he is performing, and to ensure that
they are adhered to. Grundfos recommends to follow good
practice when handling chemicals, and to use personal protective
equipment such as ventilated, enclosed goggles, face shields,
chemical aprons, boots and gloves. An eye shower may also be
advisable.

2.1.2 Sodium hypochlorite solution

If the chlorination module is part of the system, 2 % sodium
hypochlorite (NaClO) solution must be used.
Warning
Sodium hypochlorite is alkaline and will cause
oxidisation and bleaching. It is corrosive and could
cause damage to skin or clothing.
Always wear chemical protective clothing and
goggles when handling chemicals!
If splashed onto skin, sodium hypochlorite should be washed off
with fresh water. All affected clothing has to be removed. If an eye
is affected, rinse immediately using an approved eye shower or
fresh running water for at least 15 minutes, keeping the eyelid
open and rotating the eye. Seek medical treatment immediately. If
swallowed, do not induce vomiting. Keep patient warm and quiet
and seek immediate medical help. If breathing stops, apply
rescue breaths and cardiopulmonary resuscitation as necessary,
until medical help arrives.
Warning notices advising users of possible dangers should be
prominently displayed wherever sodium hypochlorite is stored,
generated or handled.
