Chapter 2. Safety Hazards, Warnings and Cautions
2.1 Safety
Incorrect set-up, maintenance, operation or modification of the Touchpoint Plus 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, this gas detection system enclosure is rated as IP65.
It 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, locking handles etc.)
• Environmental hazards (toxic atmospheres)
• Fire and Ignition hazards
2.1.1 Warnings and Cautions
Safety of this equipment is reinforced by the use of safety labels that are fixed to the equipment in a visible manner. The
labels used and their location is detailed in Ch.2.2.1 Safety Warning Labels.

by a hazard description and an internationally recognisable hazard symbol, as shown in the three example boxes below:
