WARNINGS
The following warnings are for this equipment's setup, use, maintenance, and repair. The exclamation point
symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these
symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
Failure to follow the correct information may result in physical injury which in some cases could be fatal. If the
equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
may be impaired.
WARNING
FIRE AND EXPLOSION HAZARD
The work area's flammable gases, such as methane, can ignite or explode. To help prevent fire
and explosion:
•Use equipment only in well-ventilated areas.
•Eliminate all ignition sources; such as pilot lights or cigarettes.
•Do not open the equipment in an explosive atmosphere.
•Where hazardous gases are being used, the gas exhausted from the instrument must be
piped to an area where it is safe to discharge the gas.
•It is the responsibility of the operator to determine the protection concept and classification
of equipment required for a particular application and whether these gases create a
potentially explosive atmosphere.
•Do not attempt to charge non-rechargeable batteries.
Static charge may build up on plastic parts during cleaning and could discharge and ignite
flammable gases. To help prevent fire and explosion:
•Do not clean with a dry cloth.

WARNING
INTRINSIC SAFETY
Intrinsically safe equipment that is improperly used, maintained or connected to non-
intrinsically safe equipment will create a hazardous condition and can cause a fire or explosion.
Follow local regulations and the following safety requirements.
•Only use QED-approved components.
•The equipment may be used with flammable gases and vapors with apparatus group IIA and
temperature class T1.
•The equipment can contain gas sensing heads for the detection of particular gases. The
inclusion of a sensor does not infer that the equipment is suitable for the use of gases with
a temperature class of less than T1.
•The i-Q Series is only certified for use in ambient temperatures in the range 14°F to 113°F
(-10°C to +45°C) and should not be used outside this range.
•Affinity is only certified for use in ambient temperatures in the range 14°F to 122°F (-10°C to
+50°C) and should not be used outside this range.
•The equipment must not be used in an atmosphere of greater than 21% oxygen.
•The equipment must not be used in atmospheric pressure outside of 800mbar to
1100mbar.
•Do not charge, recharge, or open in a potentially explosive atmosphere.
•For the i-Q Series Battery Pack (PMMPB), the maximum input voltage, Um, at the battery
connector shall not exceed 10.1V.
•Only battery charger type iQ-3.9 shall be used to recharge the battery pack PMMPB.
•Any damage to the equipment that could affect the integrity of the IP65 rating, must be
reported to the manufacturer.
For i-Q only:
•Use only with battery pack QED PMMPB.
•Use only with Energizer®CR2032 battery (QED part number iQ-COINCELL).
For Affinity only:
•Use only Energizer®L91 batteries.
•Do not replace the battery when an explosive atmosphere is present.
•Do not attempt to charge non-rechargeable batteries.

WARNING
TOXIC FUMES HAZARD
The i-Q Series of gas instruments can be used for measuring gases from landfill sites and biogas
plants. Toxic gases can cause serious injury or death if inhaled.
•Read Safety Data Sheets (SDSs) to know the specific hazards of the gases you are using.
•Ensure that users are adequately trained in the safety aspects of the gases being used and
appropriate procedures are followed.
•Store hazardous gases in approved containers, and dispose of empty cylinders according to
applicable guidelines.
•Ensure hazardous gases are exhausted from the instrument to an area where it is safe to
discharge the gas.
•Hazardous gases may be exhausted from the instrument when purging with clean air.
Ensure gases are exhausted to an area where it is safe to do so.
•When opening the instrument, do so in a well-ventilated area.
PERSONAL PROTECTIVE EQUIPMENT
Always wear appropriate personal protective equipment (PPE) when using the instrument.
Protective equipment helps prevent serious injury, including long-term exposure and inhalation
of toxic fumes. Given the applications of intended use, this protective equipment may include,
but is not limited to:
•Protective eyewear.
•Hearing protection.
•Protective clothing, such as footwear, gloves, or hard-hat, should be identified through a full
risk assessment.

WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•Do not use the equipment when fatigued or under the influence of drugs or alcohol.
•Do not exceed the working parameters outlined in the intrinsic safety warnings.
•The input pressure for the i-Q Series should not exceed +/- 500 mbar relative to
atmospheric pressure and the output pressure should not exceed +/- 100 mbar relative to
atmospheric pressure.
•Gas instruments are sensitive pieces of scientific equipment and must be treated as such. If
the equipment is used in a manner not specified by the manufacturer, the protection
provided by the instrument may be impaired.
•If the equipment is likely to be exposed to aggressive substances (e.g. acidic liquids, gases
that may attack metals, or solvents that may affect polymeric materials) then it is the
responsibility of the user to take suitable precautions. Contact QED or our distributor if
there are concerns.
•Do not alter or modify the equipment outside of any instructions provided by QED.
•Only QED-approved components are to be used as replacement parts. Alternatives may void
agency approvals and create safety hazards.
•The instrument has been designed to be used in explosive atmospheres as defined by the
classification. The instrument can be configured to measure low levels of several gases, but
may not be certified for use in potentially explosive atmospheres of these gases.
•Use the equipment only for its intended purpose. Contact QED or our distributors for
information.
•Repair of this equipment shall be carried out following the applicable code of practice.
•Check equipment for damage before each use. Contact QED or our distributors if there are
concerns.
•When the battery is ready for disposal, it must be disposed of under the ordinance of the
local authority and not disposed of through general waste.
•Keep children and animals away from the work area.
•Comply with all applicable safety regulations.
