2 Safety Hazards, Warnings and Cautions
2.1 Safety
Incorrect set-up, maintenance, operation or modification of the Touchpoint Pro gas detection system or its installation may
constitute a serious hazard to the health and safety of personnel and their environment. It is therefore imperative that the
contents of this chapter are thoroughly understood by everyone who has access to the gas detection system or its
associated equipment.
When properly installed, fully-enclosed gas detection systems are rated IP65.
Standard systems may be installed in a Pollution Degree 2 (i.e. laboratory, office or control room) or Pollution Degree 3 (i.e.
unheated boiler room) environment as defined by IEC/UL/EN 61010–1: Safety requirements for electrical equipment for
measurement, control and laboratory use.
In all cases, several hazards may be present when operating or servicing the equipment and extreme caution must be
exercised at all times. The hazards that may be encountered include:
Class 1 electrical hazards (AC 110/220 V, DC 18–32 V)
Mechanical hazards (Heavy components, swinging access doors)
Environmental hazards (toxic atmospheres)
Fire and Ignition hazards (Touchpoint Pro is not ATEX/IECEx Zone 1 certified, and cannot be used in flammable
atmospheres, or where oxygen concentrations >25% v/v O
