Is your cellar safe?

Is your dispensing system a
TOXIC DANGER
to your staff and customers?

Is your cellar OH&S compliant?
(AS 5034-2005)

EVERY cellar is required by OH&S
to have CO2 alarms before
the end of 2007
  • Meets AS 5034-2005 Standards (for Beverage Dispensing)
  • CO2 Compliance Monitoring (optional CO2 for Inert Gases)
  • CO2 Pre-Warning Alarm: 1.5% Vol, Final Alarm: 3% Vol
  • TWA CO2: 0.5% Vol
  • O2 Deficiency Alarm: < 19% Vol
  • Bottled wine dispensing, draught beer and ready to drink kegs
  • FCB (frozen carbonated beverages)
  • Postmix, Ready to drink (pre-mix) beverages

Background:

AS 5034-2005 (excerpts): Accidents have occurred in dispensing of beverages doe to lack of understanding of the potential damage high pressure inert gases can cause. High pressure cylinders in the supply systems for beverage dispensing can supply pressures up to 24000kPa. Due to all gas systems being under pressure, it is possible that the system and equipment connection may develop leaks., causing a build up of inert gases in cellars and low level areas with the real possibility of asphyxia (oxygen deficiency) leading to collapse and death of personnel working in these areas.

Compliance to OH& S Regulation:

  • Compliance monitoring, as per Australian Standards AS 5043-2005, of CO2 (optional O2 for inert gas system) in beverage dispensing establishments (Cellar rooms, cool rooms, ready to drink dispensing , hotels, pubs, casinos, restaurants)
  • Generation of audio-visual alarm and control of ventilation fans (including VSD fans) in case of excessive build up on CO2 leaks or oxygen deficiency due to inert gas leaks
    - Pre-warning at 1.5% Vol CO2
    - Alarm (final warning) at 3% Vol CO2
    - Optional Oxygen Deficiency Alarm at <19% Vol O2
    - Optional hand held instruments for CO2 and O2

Applications/Benefits:

  • Safety for personnel to enter or work in the cellar room or rooms where CO2 is stored
  • Safety for personnel to enter or work in:
    - Fermentation rooms
    - CO2 filling rooms
    - Laboratories and hospitals
    - Warehouse storage areas handling or storing CO2
    - Breweries, wineries and beverage filler rooms

Toxicity of CO2:

  • Effects: Rapid suffocation, nausea, dizziness & headache
  • First Aid: Remove to fresh air
    - give artificial respiration if not breathing
    - give oxygen if breathing difficulty is observed
  • Special Safety: Gas Alarm for CO2 and optional Oxygen Deficiency alarm < 19% Vol
  • TWA: 5,000 PPM CO2 (9000mg/m3) 8 hour shift, (STEL: 30,000 PPM CO2)

Description:

MSR PolyGard CELLER ALARM consists of a 2 channel main control unit SPC-03 (24 V AC/DC operation) having gas concentration display, fault LED (red), alarm LEDs (Lo-orange, Hi-red), status/power LED (green), 2 relays (30V, 1A) with built in internal buzzer. The main control unit need to be installed near the entry door of the cellar room (outside) to warn people before entering the cellar room in case of any toxic build-up inside the cellar room. Inside the cellar room (gas leak risk area) there will be the MSR PolyGard gold-plated infra-red based CO2 (carbon dioxide) sensor, installed 300-600mm above floor level, which will be connected to the main control unit SPC-03. There is also a provision for connecting a mains power supply unit (240VAC - 24 V DC) inside the cellar with integral RED flasher and buzzer to warn people inside the cellar to escape in case of gas leak beyond pre-set limit and to drive the main control unit SPC-03. THe main power supply unit will have built in power relays (240 V, 5 A) to control the ventilation fans of the cellar room (dissipate the toxic build-up. As an option, there is also a provision to install an oxygen sensor (inside the cellar room - risk area, at human breathing nose level) to the SPC-03 main control unit to monitor for any oxygen deficiency in case insert gases like CO2, nitrogen, argon are stored.

MSG PolyGard CELLAR ALARM will provide continuous monitoring of any leaking CO2 (optional oxygen deficiency) and will warn people entering the cellar room, or escape from cellar room, in case of excessive guild up of toxic CO2 (optional oxygen deficiency < 19% Vol O2) beyond pre-set limits (1.5% - Lo, 3% Vol - Hi CO2 set limits). Further the relay outputs of the CELLAR ALARM can be used for activating audio-visual alarms, shut off gas supply solenoid valves or start ventilation fans to dissipate the toxic build-up.

Specifications (subject to change):

  • Range: 0-4% Vol CO2 (Oxygen 0-25% Vol, optional extra)
  • Concentration readout display, fault LED (red), alarm LEDs (orange & red), power/status LED (green).
  • Controller Input: 4-20mA (for O2 transmitter), 0-10VDC (for CO2).
  • Controler comes with display, keypad and relays for A/V alarms.
  • Portable hand held instruments for CO2 and O2 optional.
  • Sensor: Gold plated maintenance free IR CO2 sensor with ABC (Automatic Background Calibration).
  • Power: 24V AC/DC (240VAC power supply and 1 hour emergency backup optional extra).
  • Outputs: 2x relays, SPDT, 30V 1A potential free, (set at 1.5% & 3% Vol CO2), power supply/alarm unit relays 240V 5A.
