Fixed Gas Detection – Frequently Asked Questions

How many detectors do I need?

The number of detectors required depends on several factors: 

Facility Size and Layout: Larger or more complex layouts require more detectors for adequate coverage.
 

Risk Assessment: A thorough risk assessment will identify high-risk areas that need monitoring.
 

Gas Types and Sources: The types of gases present, and their potential sources influence the number and placement of detectors.
 

Regulatory Requirements: Compliance with local regulations and industry standards often dictates the minimum number of detectors required. 

Typically, a detailed site survey and risk assessment will determine the optimal number and placement of gas detectors. 

What alarm levels are the fixed heads set at?

Fixed gas detection heads are typically set at different alarm levels to ensure early and accurate detection of gas leaks or hazardous concentrations. Commonly, these alarm levels are:
 

Alarm Level 1 (Low Alarm): Set at a lower threshold to provide an early warning, allowing for preventive action. Typically, this is set around 20-25% of the Lower Explosive Limit (LEL) for flammable gases. 

Alarm Level 2 (High Alarm): Set at a higher threshold indicating a more immediate danger and often requires immediate evacuation or emergency response. This level is usually around 50-60% of the LEL. 

Alarm Level 3 (Critical Alarm): In some systems, a critical alarm level is set at an even higher threshold, close to the LEL or occupational exposure limit (OEL), indicating a severe hazard that necessitates immediate action.
 

These levels can vary based on the specific type of gas and regulatory requirements. 

Where should the control panel go?

The control panel should be placed in a location that is: 

Easily accessible: It should be in an area where it can be reached quickly during an emergency. 

Visible and Central: Ideally, it should be in a central control room or a monitored location where it can be continuously observed. 

Safe Distance: It should be away from potential gas leak sources and hazardous areas to ensure the safety of personnel accessing it. 

Environmental Conditions: The location should be free from extreme temperatures, moisture, and other environmental factors that might affect the panel’s functionality. 

Why do I need so many audio-visual alarms?

Multiple audio-visual alarms are necessary because: 

Redundancy: Ensures that if one alarm fails, others will still function, providing reliable warning. 

Coverage: To ensure that personnel in different parts of a facility can hear or see the alarm. 

Differentiation: Different alarms can indicate various levels of danger or types of gas detected, providing clear instructions on the type of action required. 

Compliance: Many safety regulations and industry standards require multiple and redundant alarm systems to ensure adequate warning.

How often do I need to service the fixed gas system?

Fixed gas detection systems should be serviced regularly to ensure their reliability and accuracy.  

Routine Inspection: Every 6 months to 1 year, depending on the manufacturer’s recommendations and industry standards. Rockall Safety do offer service contracts, this includes:
