Chapter 4: High Performance Features and Safety

19.The HEPA filter in the enclosure will gradually accumulate airborne particulate matter from the room and from work performed in the enclosure. The rate of accumulation will depend upon the cleanliness of the room air, the amount of time the enclosure is operating and the nature of work being done in the enclosure. With normal usage, the HEPA filters will last two to five years before requiring replacement.

20.Avoid direct exposure to ultraviolet (UV) radiation; NEVER work in the Purifier Class I Enclosure when the UV light is on.

21.Ensure that the filtered enclosure is connected to an electrical service in accordance with local and national electrical codes. Failure to do so may create a fire or electrical hazard. Do not remove or service any electrical components without first disconnecting the filtered enclosure from electrical service.

22.Use of an open flame must be avoided with the enclosure. Open flames may disrupt the airflow patterns in the enclosure and cause a fire hazard with volatile solvents.

23.Increase the face velocity by adjusting the speed control of the motorized impeller or change the HEPA filter when the face velocity falls below acceptable limits established by your Safety Officer.

24.Exhaust carbon filters and HEPA filters are disposed as hazardous waste. The user is responsible for recording the chemicals adsorbed or treated by the filters and disposing properly. HEPA filters should be decontaminated before disposal on Purifier enclosures.

25.Ensure only trained operators use the enclosure. New users should review the User’s Manual and become familiar with the operation of the enclosure.

26.If the filtered enclosure is to be used in a confined space, make sure the space is well ventilated and the concentration of toxic contaminants cannot accumulate greater than the TWA.

27.Proper operation of the enclosure depends largely upon the enclosure location and the operator’s work habits. The enclosure should be located away from traffic patterns, doors, fans, ventilation registers, fume hoods, and any other air-handling device that could disrupt its airflow patterns. Consult Chapter 2: Prerequisites and Chapter 3: Getting Started sections of this manual for further details.
