4.1.4 Chemical and biological safety

D A N G E R

Chemical or biological hazards. If this instrument is used to monitor a treatment process and/or

chemical feed system for which there are regulatory limits and monitoring requirements related to

public health, public safety, food or beverage manufacture or processing, it is the responsibility of the

user of this instrument to know and abide by any applicable regulation and to have sufficient and

appropriate mechanisms in place for compliance with applicable regulations in the event of

malfunction of the instrument.

4.1.5 Ozone precautions

CAUTION

Ozone inhalation hazard. This instrument produces ozone that is contained within the equipment,

specifically within the internal plumbing. The ozone could be released under fault conditions.

It is recommended to plumb the exhaust gas port to a fume hood or to the building exterior in

accordance with local, regional and national requirements.

Exposure to even low concentrations of ozone can damage delicate nasal, bronchial and pulmonary

membrane. In sufficient concentration, ozone can cause headaches, coughing, eye, nose and throat

irritation. Immediately, move the victim to uncontaminated air and seek first aid.

The type and harshness of symptoms are based on the concentration and exposure time (n). Ozone

poisoning includes one or more of the symptoms that follow.

• Irritation or burning of the eyes, nose or throat

• Lassitude

• Frontal headache

• Sensation of sub-sternal pressure

• Constriction or oppression

• Acid taste in mouth

• Asthma

In case of more severe ozone poisoning, the symptoms can include dyspnea, cough, choking

sensation, tachycardia, vertigo, lowering of blood pressure, cramping, chest pain, and generalized

body pain. Ozone can cause a pulmonary oedema one or more hours after exposure.

4.2 Intended use

The Hach EZ-series analyzers are intended for use by individuals who measure multiple water

quality parameters in samples from industrial and environmental applications. The Hach EZ-series

analyzers do not treat or alter water and are not used to control procedures.

4.3 Product overview

The Hach EZ-series analyzers are on-line analyzers that measure one or multiple parameters in

water samples from industrial and environmental applications. Refer to Figure 1.

The sample line moves the sample into the analyzer. The analyzer uses pumps, valves and syringes

to move the sample and reagents to the measuring cell on the analytics panel. When the

measurement cycle is complete, the analyzer discards the sample through the drain line. The

analysis results shows on the display of the data processing panel. The data processing panel

controls and configures the analyzer. The data processing panel saves the analyzer data (i.e.,

trends , alarms, analysis results and data log files).

A set of reagent bottles is supplied with the analyzer to hold the reagent and solutions. Sample

preconditioning could be necessary based on the analysis technology. Optional sample

preconditioning panels are available for the sample line.

There are different analyzer series available with different measurement technology and measured

parameters:

• EZ 1000 series—On-line colorimetric analyzers for general water analysis (chemical parameters)

and nutrient analysis (i.e., nitrate, phosphate, ammonia)

• EZ 2000 series—On-line colorimetric analyzers with digestion for general water analysis (chemical

parameters) and nutrient analysis (i.e., nitrate, phosphate, ammonia)

• EZ 3000 series—On-line ion-selective (ISE) analyzers for general water analysis

• EZ 4000 series—On-line titrimetric analyzers for general water analysis (chemical parameters)

• EZ 5000 series—Multiparametric on-line titrimetric analyzers for general water analysis (chemical

parameters)

• EZ 6000 series—On-line voltammetry analyzers for heavy/trace metal analysis (e.g., Ag, As, Cr,

Hg, Pb, Se)

• EZ 7x00 serires—On-line analyzers for industrial applications (e.g, COD, TOC, Total Nitrogen,

Total Phosphorus, volatile fatty acids FOS/TAC, influent toxicity, international bitternes units,

Adenosine Triphospahte)

The EZ-analyzer has different options such as: Sample detection, level detection for reagent bottles,

remote Start/Stop, auto-validation, auto-calibration, auto-cleaning, RS232 and Modbus.

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the

document.

5.1 Installation guidelines

WARNING

Fire hazard. The user is responsible to make sure that sufficient precautions are taken when the

equipment is used with methods that use flammable liquids. Make sure to obey correct user

precautions and safety protocols. This includes, but is not limited to, spill and leak controls, proper

ventilation, no unattended use, and that the instrument is never left unattended while power is

applied.

CAUTION

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective

equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets

(MSDS/SDS) for safety protocols.
