Note: Ashley Peters, Bob Broug and other staff in the area experienced various reactions to the new chemicals - smell, stinging eyes + irritated throats were some of the problems.
14 Robyne White, a radiographer employed by NSCCAHS at the time of the offence also said in evidence that she mixed the new chemicals sometime around the end of July 2001. She thought the date may have been 28 July 2001. She recalled that earlier she had had a conversation with Mr Broug during which they discussed the new chemicals. She said that the boxes containing the new chemicals were marked "new" and a notation was made on a whiteboard to the effect that the chemicals were not to be used. Mr Broug she said nevertheless used them on 27 July because the hospital had run out of the old brand. Shortly after that she also used the new chemicals. She experienced runny eyes. She observed that the new chemistry was different in colour from the old brand and that it was foaming, "...like a head of beer". She made an entry in the Hazard Register recording her observations. She also thought she contacted Mr Broug and Mr Horner about the incident.
15 On Friday 10 August 2001 Mr Broug purged and cleaned the chemicals from the x-ray processing machine. The reason he did this was because of the complaints from staff about the smell of the new chemistry and the scum in the tanks. At this stage there had been between eight to twelve mixes of the new chemistry by radiographers. When Mr Broug commenced purging and cleaning he first noticed a scum forming in the tanks which later formed into granules. Mr Broug wore protective clothing at the time including a face mask. He felt a burning sensation on his skin. Other people had gone to casualty complaining of feeling ill. Mr Broug developed a bad headache and went to casualty where he said he was diagnosed with high blood pressure. Shortly after that the department was closed down. Later Mr Broug was asked to return to the department and retrieve a sample. That evening Mr Broug experienced hot burning eyes which he said was akin to conjunctivitis. The next morning he could not open his eyes. His nose was bloodied. He also felt very depressed and developed a rash.
16 Ms White started work at Wyong hospital on 10 August 2001. Upon entering the building she noticed a very strong smell. She saw Mr Broug cleaning the processor. She opened a number of doors in order to let in some fresh air. Later she felt dizzy, nauseous, a burning and tightness in her chest and she developed a severe headache. After spending several hours in accident and emergency she filled out an Incident Report and drove home.
17 Nurse Haywood was also on duty on 10 August. She recalled a strong chemical smell at Wyong hospital that day and developed a number of symptoms including headache, nausea, burning on the skin and an ache in the stomach area. She also spent time in accident and emergency.
18 Mr Peters on 10 August 2001 also experienced adverse effects after smelling what he described as an odorous smell in the medical imaging department at Wyong hospital. He attended the casualty section of Wyong hospital for treatment.
19 Francis Leung the manager of the medical imaging department on 10 August 2001 and one of Mr Broug's supervisors explained that on the day Ms White contacted him and told him that staff at Wyong hospital had been overcome by chemical fumes from the Fuji Hunt product. Mr Leung instructed her to close the department and then seek medical assistance. He then contacted the defendant and spoke to John Gaunt. Mr Gaunt promised to send a technician to Wyong hospital to clean the processor and remove the Fuji Hunt product. Mr Leung then rang the director of medical services of Wyong hospital, Dr Andrew Lancaster and informed him of the incident and of his decision to close the department. He asked Dr Lancaster to increase the ventilation in the department in order to get rid of the fumes. Later that day a technician in the defendant's employ Martin De Rooy arrived at Wyong hospital and after some brief instructions from Mr Broug he proceeded to flush the system through, remove the Fuji Hunt product and replace it with the Ilford product that he had collected from Gosford hospital en route to Wyong hospital. Mr De Rooy did not, contrary to Mr Leung's request to Mr Gaunt, remove the Fuji Hunt product from the premises. Nor did Mr Leung who assumed it would be removed check to ensure that it had been removed. Nor it appears were any weekend staff told of the incident of 10 August 2001 or given any instruction about using the Fuji Hunt product.
20 Mr Broug understood from what he had been told by Mr Leung that after 10 August all Fuji Hunt products had been removed from Wyong hospital. The failure to remove the product or to ensure that it was removed had the predictable result that it was used again on the weekend to top up the developer mixing tank, attached to the x-ray processing machine.
21 On Monday 13 August 2001 staff again complained of an offensive odour. In addition certain staff complained of symptoms similar to those experienced by staff on 10 August 2001. The department remained open for a short period that day and then later was closed.
22 On 10 August Mr De Rooy took samples of the chemistry from the mixer and processor at Wyong hospital. On 22 August Mr Gaunt sent the samples to Chemika Pty Limited. A letter of that date from Mr Gaunt to Dr Doughty then the chief chemist at Chemika Pty Limited requests an analysis of the Fuji Hunt product by Dr Doughty in order to ascertain the identity and contents of the chemistry and the mix by concentration of that chemistry, so that the defendant can,
