3 Safety
3.1 Safety Instructions
Do not endanger yourself and other people. Please read the following safety instructions before
performing installation, operation and maintenance of fittings. They enable to avoid dangers to
people and units. Handling of technical gases – especially flammable or toxic gases – requires
knowledge of the subject, observation of instructions for use and special safety measures. In addition, regulations
and rules must be followed as applicable. (see 3.2)
Use these units only as intended (see section “Intended Use”). The same is valid for the used gas: improper use can
cause damage of the unit or injury and even death of persons.
Use gas detection devices, if you work with dangerous gases. These products detect leakage and warn the
personnel.
Wear gas mask, protection glasses and protection gloves, if you work with toxic gases and provide good ventilation.
Make sure that venting openings are not clogged and toxic gases will be discharged in use with pressure reducer
and plants equipped with relief valves.
Some gases can cause suffocation, because they displace oxygen from air. Ensure good ventilation, if you work with
these gases. It is recommended to install detectors which give an alarm if there is a lack of oxygen at the working
place.
