The South African experience in regard to neighbourhood mill and mine populations is also causing me some concern. The saving feature here has been the limited number of persons involved and the high labour turnover. (emphasis added)
On 6 August 1963 Dr McNulty inspected the handling of blue asbestos at Fremantle wharf. On 7 August 1963 he reported to Dr Jarvis as Senior Medical Officer of the Central Committee as follows (PX 37(277)):
The asbestos was on board the "Kangaroo" and had been loaded at Port Samson. It had been pretty well bagged although a few bags had burst open liberating some of their contents. There was no visible dust in the atmosphere but there were small scattered tufts of blue fibre lying about the dock and hold. It seemed doubtful that much, if any, dust of a respirable size would be liberated during handling and since contact with the fibre is very occasional and intermittent, no health hazard to the waterside workers at Fremantle would be expected.
It is probably advisable that steps should be taken to clear up the spilt fibre on the wharf and the hold . (emphasis added)
It is relevant that Dr Jarvis concluded his letter of 1 May 1963 with these words:
I would finally comment that I am seeking information or advice from you in my capacity as medical adviser to the employers of waterfront labour, and not on behalf of the Federal Advisory Committee.
In a note to Dr Letham written on 24 April 1963 concerning the possible health hazards of asbestos to waterside workers Dr Jarvis observed that:
Mr Roach [representative of the Waterside Workers Federation on the FAC] has become quite active recently in looking for all sorts of health hazards in all sorts of places.
In his letter of 21 May 1963 to Captain Dalziel of the Central Committee forwarding the opinion of Dr McNulty (before Dr McNulty had made his inspection of 6 August 1963) Dr Jarvis said:
While I do not wish to attract undue attention to the projected Health Departments of the handling of the June shipment, I think it necessary to mention Mr Groom [State representative of the Central Committee] to enable Dr McNulty to inquire about shipping dates if necessary … I have thought of suggesting that you let Mr Fleming [the Authority representative on the FAC] know that I have made this inquiry of the State Department, but if you do, doubtless he will have local representative in Fremantle wanting to join the party, and the next thing that would happen would be that the WWF would want to come into it also , a position which might embarrass Dr McNulty. (emphasis added)
I do not believe that it was Dr McNulty who may have feared embarrassment but rather the Central Committee. In his letter of 28 August 1963 forwarding the report of Dr McNulty on the ship inspection of 6 August 1963 to Captain Dalziel, Dr Jarvis added (PX 37(278)):
… I think we may not yet have heard the last of this subject. Do you mind, please, mentioning it to Mr Oswald-Jacobs [of the Central Committee, Chairman of FAC] prior to the next FAC meeting. He may have an opinion as to whether Dr McNulty's letter should be tabled on our initiative, or alternatively, should not be mentioned unless and until the topic is raised again by Mr Roach or by Mr Fleming.
The report was not tabled at the next meeting of the FAC and the matter not raised. Nor was the earlier advice of Dr McNulty concerning the hazards of blue asbestos disclosed. I infer from the correspondence of Dr Jarvis, and his failure to produce the McNulty opinion to the FAC, not that he intended to conceal a known danger, but that, having satisfied himself of the matter, he wished, in the interests of his employers, the Central Committee, that there be no further debate or investigation. Of greater relevance is that the survey to which Mr Fleming of the Authority agreed was never commissioned by FAC nor conducted by the Authority.
Dr Jarvis was not unconcerned with safety, as is shown by his letter of 1 May 1963 to Dr Letham. A meeting of the FAC on 16 October 1963 recorded the recommendation of the Hobart Port Advisory Panel that the FAC formulate general guidance on suitable respiratory protection for the handling of various harmful irritant and obnoxious cargoes. Dr Jarvis was not present at the meeting but his general view, previously expressed, that such general guidance was necessary and should be reduced to writing, were recorded.
An insight into the thinking of Dr Jarvis and his perceptions of his duty is given by a short letter he wrote to Dr Dalziel on 22 April 1968 in these terms (PX 37(270)):
Thank you for the cutting of the newspaper article on the above subject and it does seem to me a pity that this sort of thing has to be pushed by the unions, although I suppose it is inevitable. Reports are regularly appearing in medical literature about these cases of mesothelioma and it does seem very likely that some cases are associated with exposure to asbestos.
I should here record that Dr Jarvis is of advanced years and in ill health. It was not possible that he give evidence in this matter as was desired by counsel for AEWL.
The members of the FAC received the minutes of the Port Advisory Panels. The minutes of the Melbourne Advisory Panel meeting of 4 November 1964 record the following (PX 37(206)):
Asbestos hazards - precautions in handling
Mr Swayn (WWF) stated that the Branch had received literature from their Federal office referring to pulmonary effects of asbestos dust in industry and that his members would like to have the possibility of asbestos dust having any cumulative affect investigated, and if necessary, further precautionary and/or protective measures introduced. It was decided to refer the matter to Dr Jarvis.
The minutes of the following meeting of 24 February 1965 record this (PX 37(207)):
Asbestos Hazards
The secretary reported that the matter had been referred to Dr Jarvis, and that an inspection by Dr Jarvis and Dr Milne, (Industrial Division, State Department of Health) had taken place, he understood that Dr Jarvis intended to make further inquiries.
Mr O'Neil stated that this matter had been raised some years ago and at that time, the medical opinion was that owing to the intermittent exposure to asbestos dust, there was no danger to waterside workers . (emphasis added)
In the light of the then known hazards of blue asbestos such medical opinion if it had been given was plainly wrong. The reservations of Dr McNulty had not been conveyed to the FAC however Dr Jarvis had noted the dangers of blue asbestos at the FAC meeting of 17 April 1963 attended by Mr Fleming of the Authority.
On 1 December 1965 Mr Roach of the Waterside Workers Federation proposed to the Committee that a conference be held at national level to meet and discuss with scientists the problems associated with fume and dust hazards experienced within the waterfront industry, together with recommended procedures for their abatement. Such a conference could, he said, result in a national policy for control and abatement of dust. After investigation by Dr Jarvis and Captain Dalziel the Committee on 9 March 1966 rejected this proposal as impractical because "no all embracing policy nor procedure could possibly cover all situations".
It was agreed that the question of ventilation in ship holds might profitably be examined. A telegram was dispatched to the OHC requesting general advice on fume, dust and gases hazards. In response the OHC sought more specific terms of reference. It was agreed at the meeting of the FAC of 13 April 1966 that a programme be drafted listing types of dust and the varying circumstances under which they are encountered for submission to the OHC. As an interim measure Dr Gordon Smith, the secretary of the OHC was invited to address the next meeting of the FAC.
On 1 June 1966 Dr Smith attended a meeting of the FAC. Representatives of the Authority (Mr Buckland) and AEWL (Dr Jarvis) were present (PX 37(135)). Mr Roach tabled a document referring to the hazards of dusts, vapours and gases in which he said:
… failure of quick recognition of these hazards, by both management and labour, often causes the job to be worked without proper attention to protective equipment, including ventilation, thus accentuating the hazards involved.
In addition, methods of ventilation are too often left to people, such as foremen, who know little about either the reasons for ventilation or ventilation itself. The stevedoring companies … do not possess anything that borders on adequate ventilation equipment.
It was again agreed by the Committee that a list of bulk cargoes would be compiled for submission to the OHC with particulars of the nature of exposure to the substances. Detailed notes of this meeting are in evidence (PX 37(295)). Mr Buckland, representative of the Authority, after speaking of asbestos said "I feel sure in certain cases the labour do not appreciate the hazards involved". The following exchange also occurred:
Mr Roach (WWF) The question of dusts. Is it desirable that the men should work in extremely dusty atmospheres if dusts can be allayed or extracted in a normal industrial hygienic process.
Dr Gordon Smith General answer is no. The exposure to dusts should be reduced to a limited degree if possible. What is done will depend on type of dust and circumstances. We take the view that no dust is completely harmless. The effect upon the respiratory tissues is bound to be adverse if a man is exposed to vast quantities of any dust.
On 20 January 1967 a list of six selected bulk cargoes together with "details on handling methods" was sent by FAC to OHC (PX 37(288)). This revealed no more than that 49 shipments of bagged asbestos averaging approximately 200 tons was "manually handled discharged in slings or on trays with ships gear". It is apparent that the actual tonnage of cargo discharged in Sydney was 21340 tons. This error was corrected after March 1969. See letter, undated, tendered as SIFC 1(46) and minutes of 18 March 1969 page 2 (SIFC 1(48)) but the letter gives no hint of the real conditions of exposure.
By 17 October 1968 no reply had been received by the FAC from the OHC. The Hobart Port Advisory Panel of FAC asked Captain Dalziel whether another authority could be approached for advice. Captain Dalziel informed that Panel that "the Occupational Health Committee is the only Authority that can decide on certain matters". When this enquiry was mentioned at the FAC meeting on 17 October 1968 Dr Jarvis regretted that "other questions we have put to the OHC up to 3 or 4 years ago still remain unanswered".
On 4 December 1968 a letter was sent by FAC to OHC requesting some response (PX 37(152), PX 37(153)). On 13 February 1969 Captain Dalziel and Captain D M Hogge (the secretary of FAC) attended the School of Public Health and Tropical Medicine in Sydney, the relevant address of the OHC, to discuss the delay. They were informed that asbestos was to be given top priority in the list of gases, dusts and fumes to be investigated by OHC on behalf of the FAC. FAC was asked to provide up to date information regarding the amounts of asbestos handled and methods of handling together with some information on the degree of exposure of waterside workers. On the occasion of this visit Dr Ferguson of OHC informed Captains Dalziel and Hogge that he was presently of the opinion "based on the apparent degree of exposure to individual waterside workers that the hazard is small or non existent".
The information requested by the OHC was apparently forwarded by FAC. This undated document again gives no indication of the dust generated in the handling of asbestos, recording merely that 20000 tons in hessian bags, lined and unlined was unloaded in Sydney annually. The information concerning individual exposure was contained in the following passage:
Exposure
It appears, by relating estimated man-hours worked on asbestos to estimated monthly man-hours worked, that the percentage of total working time spent on asbestos is very small.
Estimation of exposure to individual waterside workers, in general terms, is not practicable for the following reasons:-
(1) A shipment may be in several parcels, in a number of holds in a ship which is working three shifts, producing a situation of minimum exposure to a maximum number of men.
eg 5 gangs, 3 shifts = 180 men
9 gangs, 3 shifts - 324 men
(2) A shipment may be in one parcel and be worked on the day shift only, producing a situation of maximum exposure to a minimum number of men.
eg 1 gang, 1 shift = 12 men
(3) Any combination of circumstances between the above extremes is possible.
No information relating to the actual conditions of exposure in which the men worked was conveyed to the OHC.
Under cover of a letter dated 2 September 1969 Dr D A Ferguson forwarded the report of OHC entitled "Asbestos on the Waterfront" (PX 37(286)). In his letter Dr Ferguson stated that the OHC having considered the problems associated with handling of asbestos on the Australian waterfront "Is of the opinion that a health hazard is unlikely to be presented to waterside workers engaged in unloading the material from ships". He added that notwithstanding this opinion "The committee stresses the need for all concerned to minimise the exposure of all persons to asbestos dust". The reason for such caution is apparent. The report recorded one measurement of atmospheric fibre concentration taken when men took unlined hessian bags from lockers at 45 fibres per cubic centimetre. Accepting as a standard of safety two fibres per cc daily for 50 years (below which some workers but less than 1 per cent developed clinical signs of asbestosis) the report asserted that exposure to 50 fibres per cc for five shifts per year is without risk to waterside workers. It is noteworthy that Mr Major, who prepared the report, also recorded that "there is no average dust concentration to which wharf labourers are exposed" because of the variables including "the handling practices of the individual workmen". Further Mr Major observed that while he was told it may be improbable that any man worked more than three shifts per year on asbestos cargoes FAC ought make further inquiries of stevedores in this regard.
Evidence has been given that the sampling methods used by Mr Major have a potential error of 50 per cent. That is, the actual concentration of fibres in the atmosphere tested may be half or double that recorded (Transcript page 743). If the actual exposure of the men was to a concentration of 100 fibres per cc throughout each shift, and the days of exposure numbered 10 per year a simple calculation is possible. The relationship between time and concentration of fibre is linear.
50 years x 250 working days x 2 fibres per cc equals 25,000 fibre days.
50 years x 10 working days x 100 fibres per cc equals 50,000 fibre days.
Relatively small changes in assumptions increase the hazard to an unacceptable degree even on a standard pursuant to which some (though less than 1 per cent) workers will contract diseases with possibly fatal ramification.
Mr Major no doubt conscious of these matters declared in his report an intention to inspect and sample the air in most ships carrying asbestos when they arrived in Sydney so as to identify practices which result in unnecessary exposure. "Prudence" said Mr Major "suggests that … exposure be minimised" and "somehow it should be brought to the attention of all in the waterfront that all reasonable steps should be taken to limit the amount of asbestos spillage during loading and unloading" and "experienced stevedores would easily find … practices … which could reduce the amount of asbestos fibre rendered airborne".
Upon receipt of this report the FAC resolved that a code of practice be drawn up for the handling of asbestos. Subcommittees were formed for this purpose in Sydney, Melbourne and Adelaide. The meeting of FAC on 3 December 1969 noted that reports received from subcommittees made clear that unlined hessian bags emit dust even when undamaged and that pre-palletised asbestos would greatly reduce spillage and consequent dust. A precis of the report from the OHC was in December 1969 sent to each stevedore and agent.
In June 1970 the plaintiff was issued with a power crane and forklift ticket. He was not thereafter exposed to those very high concentrations of asbestos dust previously described.
On 2 December 1971 the FAC resolved that the UK code of practice for handling assignments of asbestos fibre in British ports (sent to FAC by the OHC) be adopted in Australian ports pending the issuing of a code by the National Health and Medical Research Council.
