1-10 Safety High Voltage Connections Careful checks should be kept on the lamp connections and high voltage connections within the equipment to make sure that these do not become dirty or coated with powder or other possible conducting material. They should be cleaned regularly, at least whenever the lamp is changed, possibly more often where a particularly heavily polluted atmosphere occurs.
Safety 1-11 Safety UV curing NOTE: The subtrate collection tray on the outfeed of the unit forms part of the UV shielding. If this tray is not fitted alternative shielding methods must be provided for operator and bystander safety. UV measurements in the infeed chamber at belt level are 20 Micro Watts/cm2. If gloves and glasses are not used, then exposure to the UV should be limited to no more than 4 mins per day. UV measurements in the delivery tray are between 0.8--1.0 Micro Watts/cm2. U.V.
1-12 Safety Ozone Gas Ozone is generated by reaction of short-wave UV radiation on air and is a gas which readily reverts to oxygen when mixed with atmospheric air as it is removed from the source of UV radiation. Quantity of ozone produced equates to 0.001 cu.ft/kWHr. NOTE: Ozone should be ducted via a sealed duct to atmosphere and discharged according to local regulations. (Height and clearance from pedestrian walkways and opening windows, etc.).
Safety 1-13 Ozone poisoning should be treated symptomatically. This may include bed rest, analgesics to relieve pain, and antibiotics as may be prescribed by a medical practitioner. Further details can be found on Guidance Note EH 38 from the Health and Safety Executive. Mercury Mercury is a silver colored liquid which is contained in medium pressure mercury arc lamps. In the case of Primarc lamps this is typically 0.5 -- 2g.
