DETECTORS & ALARMS

In most industries, there is often a need for protection against possible hazards such as lack of oxygen, explosion and toxic gases. Portable gas detectors and stationary gas alarm systems can be used for continuous measurements of the above hazards. The gas detectors send alarms or warnings as soon as a danger occurs, giving the user time to leave the area or to start an action, such as increasing ventilation in the room or area. Portable gas detectors are used in connection with work in tanks, containers, confined spaces and sewers to analyse whether the work environment is safe prior to entry and while working in the area. Portable gas detectors are available as single or multigas detectors, and can be configured with different sensors for measuring different gases.

Depending on the number of sensors, at the same time the equipment can be set to detect and measure:

  • Lack of oxygen or increased oxygen content
  • Explosive gases and vapours
  • Toxic gases

MOST COMMON SENSORS

  • O2 Oxygen
  • EX Explosive gases
  • H2S Hydrogen sulphide
  • CO Carbon monoxide
  • NH3 Ammonia
  • CO2 Carbon dioxide
  • NO2 Nitrogen oxide
  • Cl2 Chlorine
  • ClO2 Chlorine dioxide
  • SO2 Sulphur dioxide
  • PH3 Phosphine
  • HCN Hydrocyanic acid, prussic acid

ICM SAFETY SERVICE


Gas detectors can be life-saving devices, which is why it is crucial to have them inspected and calibrated. Entering contaminated areas, such as confined spaces or wells, with a faulty gas detector that does not specify the actual values can be fatal. Under normal circumstances, our gas detector suppliers recommend calibration and inspection according to regional standards or the industry's 'best practice'. We usually recommend that you calibrate your gas detectors at least once every 12 months.

A SAFETY Service solution within gas detection includes:

  • Calibration and maintenance control of portable gas detectors

  • Calibration and inspection of stationary gas detectors.

  • Replacement of defective and worn sensors

  • Gas detector repair

Please be aware that in order to keep the guarantee of sensors, rechargeable batteries, cabinets and electronics, the gas detectors must undergo an annual maintenance check as well, which we naturally carry out at the same occasion.

PORTABLE & STATIONARY EQUIPMENT


Monitoring of gases in factories and production plants is now mandatory in most industries. Explosive gases are used as energy sources while explosive liquids are used as raw materials or semi-finished products. Industrial raw materials almost always contain toxic gases and vapours; they exist in the form of emission gases. Personal protective equipment and gas detection are required to protect production and employees. If portable gas detectors do not do the task, or require additional supplementation, stationary gas detection may be necessary for automatic monitoring. Stationary gas detectors are permanently installed. Locations for monitoring are determined and safety measures automatically applied in case of a danger, e.g., through visual and acoustic alarms, automatic shut down of production equipment, automatic start of ventilators etc. Stationary gas detectors measure continuously, provide automatic alarms and control processes. ICM offers both portable and stationary gas detector equipment. Additionally, our service department commissions and services both portable gas detector and stationary gas detector installations.
