Arbejdstilsynet (AT)
(The Danish Working Environment Authority)
Under the heading “Køleanlæg og varmepumper. AT vejledning B.4.4, januar 2005” the Danish Working Environment Authority issued a set of official guidelines with information about the special requirements that apply to the installation, layout, maintenance and use of refrigerating systems and heat pumps. The following is an excerpt from those guidelines – focusing on the use of gas detection in the mentioned context.
3.3.3. Gas alarm systems in engine rooms
In connection with the use of CO2 as a refrigerant or a refrigerant in group 1, the room should have a gas alarm system that is specifically designed to monitor the refrigerant in question. If the refrigerant is in group 2, the detection system may consist of an oxygen monitor.
The emergency ventilation and alarm system must be activated automatically in connection with low alarm.
The refrigerating system must shut down automatically in connection with high alarm.
The emergency ventilation and alarm system must be operational independently of the refrigerating system and its supply voltage, also in case of an emergency shutdown.
Example of suggested gas alarm limits for ammonia:
| |
ppm |
| Low alarm |
500 |
| High alarm |
30.000 |

RMG-Inspektion A/S
RMG-Inspektion A/S is accredited by DANAK (the Danish Accreditation and Metrology Fund) as an independent inspection company authorised to inspect and approve automatic gas alarm installations.
It is normally a requirement that automatic gas alarm installations must be inspected and approved by an independent inspection company like RMG-Inspektion A/S. The inspection of automatic gas alarm installations is carried out for the owner of the installation as annual inspections – or for the installation company as an initial inspection of a newly established or expanded installation. Geopal System A/S is prepared to offer assistance in connection with these inspections to ensure that the owner of the installation gets the necessary guidance and advice.
