Page 3: General Description
General Description 1.1 Your BioMAT 1 Microbiological Safety Cabinet has been designed to provide optimum performance for operator protection. Using the latest in microprocessor and fan technology, it is designed to exceed the performance requirements of the European Microbiological Safety Cabinet Standard EN12469:2000.
Page 4: Quality Assurance
Ø Extension, modification, relocation, repairs or other maintenance is carried out by CAS personnel or persons authorised by CAS or, in the case of electrical work, by qualified electricians. Ø In the case of repair or maintenance, replacement parts supplied by CAS must be used.
Page 5 Cabinet Siting 1.3 The siting of your Safety Cabinet is extremely important. Air currents and the movement of people in the laboratory can adversely affect the performance. Safety Cabinets should be sited away from; Ø Doors and windows which open Ø...

Page 11: Start-Up Procedure
Start Up Procedure 2.2 The following notes are for guidance where local laboratory instructions do not exist or are inappropriate. They should complement, not replace, existing codes of practice issued by your Laboratory Safety Officers. Ø Ensure power supply to the cabinet is switched on, as evidenced by the main display being illuminated.
Page 12: Shutdown Procedure
Shut Down Procedure 2.3 Ø The work area should be cleared of any apparatus / equipment and cleaned in accordance with laboratory codes of practice. The cabinet should be left running for a few minutes to clear any residual aerosols. Ø...
Page 13: Cleaning Procedure
Cleaning Procedure 2.4 Regular cleaning is very important to prevent the build-up of dirt and hence potentially infectious material. Routine swabbing of work surfaces with 70% v/v IMS (ethanol) or IPA (Isopropyl Alcohol) is recommended. For cleaning the work surfaces, swabbing with a mild detergent in warm water is very effective.
Page 14 A convenient way of generating sufficient formaldehyde is to boil off Formalin (40% formaldehyde BP or equivalent) in a suitable vessel such as a formalin vaporiser. These are available from CAS. Always consult your Laboratory Safety Officer prior to fumigation of a safety cabinet.
Page 15 Fumigation Procedure 2.6 Ø Switch off the cabinet fans by pressing the green button A on the control panel. Ø For re-circulating type safety cabinets the fumigation extract kit (optional) should be fitted to the cabinet discharge and ensure that the manual damper is fully closed. For cabinets connected to a duct system proceed as follows: §...
Page 16 For re-circulating type safety cabinets press the fumigate button to complete cycle and open the manual shut-off damper on the fumigation adaptor kit (Optional) having first fitted the extract tubing and placed the discharge point in a location approved by the Laboratory Safety Officer.

Page 18 Ultraviolet Radiation (Optional) 2.8 Ultraviolet Radiation (UV) lamps may be fitted as an optional extra; these can be fitted as new in our factory or retrofitted at a later date on site. If installed the cabinet will have1 or 2 (Depending on cabinet size) short wavelength Ultraviolet (UV) tubes emitting 254 nano metres fitted to the inside work area of the safety cabinet.
Page 19 Typical display during normal operation shown below: AIRFLOW SAFE BioMAT 1 In the event of an alarm condition the display will clearly indicate the fault; this will remain displayed until fault is rectified.
Page 20: Alarm Circuits
Alarm Circuits 3.2 There are three standard alarm circuits on the BioMAT 1 Re-circulating and Exhaust type Safety Cabinets. INFLOW LOW ALARM Sensed by an accurate pressure sensor mounted on the main printed circuit board and connected via tubing to the sensing points within the cabinet body, this will sense low airflow caused by fan failure or filter soiling, and transmit the signal to the display meter on the front panel and alarm circuit.
Page 21: Electrical Protection
Electrical Protection 3.3 Ensure the Safety Cabinet is isolated from the mains supply prior to opening access panels. Warning Fuses There are 11 fuses mounted on the printed circuit board to protect the electrical circuits of the cabinet. The cabinet controls are housed behind the front control panel which is secured with two screws located across the bottom edge.
