4.Method / Procedure-kindly please refer to the manual attached.5b. Substances used which have potential to cause harm (potential hazard)

NB: This section is concerned with hazards inherent in the substances rather than the way they might be used in this procedure. All columns must be filled according to Safety Data Sheet.SubstanceHazards identified(e.g. toxic, flammable)MEL or OEL (if assigned - do not quote LD50 etc.)Precautions in handling(if gloves required state type)Emergency action in the event of spillage etc.

Rubber EffluetToxic--Proper PPE including face masks, gloves and goggles should be worn througout handling.- Safet boots and lab coats should be worn during collection of rubber effluent.-shovel up the spilled effluent and place it in the empty container.-spray residue with plenty of water.

5b.Equipment used in the procedure which may cause harm

NB: This section is concerned with hazards inherent in the equipment rather than the way it might be used in this procedure.EquipmentNature of hazardPrecautions to be taken

TurbidimeterElectrical HazardAlways diconnect power from the instrument before attempting any closing operations. Remove any cuvette that still in instrument and dispose them and their contents using an approved disposal method.

HDR 890 CalorimeterElectrical HazardAlways diconnect power from the instrument before attemoting any closing operations. Remove any cuvettes that still in instrument and dispose them and their contents using an approved disposal method.

pH meterElectrical HazardAvoid measuring harsh chemicals such as highly caustic solutions (e.g. pH Up and silica additives), or concentrated solutions such as raw nutrient. Avoid placing the electrode in oily solutions as they can coat the electrode. Filter water samples that are potentially a problem (i.e. greasy) prior to performing a pH measurement. Clean the electrode regularly using an electrode cleaner

NOTE:

ALL EQUIPMENTS USED ELECTRICAL POWER WILL HAVE ELECTRICAL HAZARDS.

7a.Specific risk assessment for procedure and precautions to be taken During preparation of reagent solutions there is a LOW risk of contact with hazardous chemicals if all precautionary measures stated in Table 5a and b (handling) are followed.

Extra care must be taken to avoid chemical spillage. PPE must be worn at all times. Work in a well-ventilated area (i.e. fume cupboard). Turn on electrical equipment ONLY after all components have been connected, and the cables checked for any damage.

After following all the above precautions the overall risk assessment for this procedure is LOW.PAGE 1
