2 Preparation of Reagent DEOX/2000®
WARNING: Wear recommended protective goggles when servicing the
wet components of the analyser, particularly when servicing reagents and
reagent lines. The analyser uses chemicals that can cause severe personal
injury by chemical burns on contact with eyes. Rinse any area of contact
immediately. If chemicals contact eyes, rinse with copious amounts of
water and seek immediate medical attention.
WARNING:
pH4 buffer and acetic acid will severely irritate eyes and cause
chemical burns to skin. Always wear appropriate protective equipment
during handling. When diluting acid, always pour the acid into the water,
never pour water into acid. Use caution when disconnecting the reagent
tubing and avoid contact with any fluid that drips from the open end. It
is the responsibility of the user of the equipment to obtain and follow
the safety precautions of the manufacturer of the hazardous material.
WARNING: Chemicals for industrial use: vapour may be harmful if
inhaled and may be fatal if swallowed. Liquid may cause severe burns to
skin and eyes. Avoid contact with eyes, skin, or clothing. Wash thoroughly
after handling. In case of spill, soak up with sand or earth.
