(Para 16.6 of Report by Study Team `B').
3.2 Mines Act; Regulations & Rules Thereunder.
3.2.1 The regulations and rules made under the Mines Act 1952 need to be modified to bring them upto the International Standards for the control of asbestos fibre dust during mining,

Act so far as they relate to asbestos fibre dust control.
3.2.3 Asbestosis; lung canceFand mesothelioma when they are caused by asbestos should be notified as occupational diseases under the Mines Act.

7.1 \\
For licencing/registration of new units, specific requirements of dust control to be met by them should be listed out by the competent authority. Licence should be issued by the competent authority only after satisfying itself that such requirements have already been included in the project. (Para 16.8 of Report by Study Team TF).
4. Small Scale Industry.
i
7.2 ^j u ?
Management and control of asbestos dust in the small scale sector of the industry need to be
tackled on priority basis. Major recommendations in this regard are :
.
-- Financial : Subsidy should be given for the purchase of equipment needed for the control of
I
dust, personal sampling etc. Capital assets under this category should not be counted for
the capital investment clause which determines classification for small scale sector.
_ Engineering : A technical cell in D.I.C. or other concerned agency should be directed to
pool the technology for the suppression/control of asbestos dust and to help the Small-Scale
Industry to select and install appropriate equipment.
-- Measurement and Health Control : The Small Scale Industry should be encouraged to pool their resources und establish a centralised dust counting centre, as also a health surveillance centre under the supervision of a competent qualified person.
_ Education : Employees in this industry should be made aware ot the need tor strict imple.
mentation of the asbestos regulations and the health hazards that might arise due to occupa tional exposure to asbestos.
tPaia 16.7 of Report by Study Team ' B').
5. Compliance of Regulations.
5,1 Packing of raw asbestos fibre should be in impermeable bags and should be handled as unitised loads as far as it is practicable. ISI may be requested to bring out the Code of Practice for packing, handling, transportation and use of asbestos fibre. (Para 16 1lo t Report by Study Team `B'h
7
y2 F.fTectivc Steps to implement the Rules must be taken by providing all facilities to the state regulatory agencies. These include dust monitoring equipment and specialised trained man power in order to produce accurate and reproducible results.1 (Para 16.3 of Report by Study
Team 'IV). 5 -j The industry should periodically monitor dust levels to ensure the efiectiveness ot the
engineering controls. (Para 9.2 of Report by Study Team `B'). 5.4 Government should be liberal in allowing the import of equipment required tor the use in
dust monitoring & medical surveillance. (Para 16.13 of Report by Study le an t B ).

Medical Surveillance. 6.1 All the workers likely to be exposed to asbestos fibres should be covered by a well defined
medical surveillance plan with no cost to the employee. (Para 27.2 of Report by Study
Team *A'}.
6.2 . Health education of workers is an important object ot 'medical surveillance programme.
(Para 28.1.2 of Report by Study Team `A')-
1
6.3 Frequency of periodical medical examination should take into account age, service ot employee and his exposure profile which includes his exposure level in relation to action
level. (Para 29.3 of Report by Study Team `A')-
6.4 Medical records along with periodic exposure profiles should be maintained for 40 years alter employment or 10 years after cessation of employment.: (Para 32.2 ot Report by Study
Team `A').
I 7, Compensation.
i* i
un r `
7 j The employees covered under the ESI Act should also be eligible for compensation alter cessation of ESI coverage, as is the case in Workmen's . Compensation Act. (Para 16.12 ol
Report by Study Team `B'). Employees not covered under the ESI Act should be covered un(ier general insurance, at no cost to them. (Para 14.6 of Report by Study Team `B').
7'2 Clear criteria for the diagnosis of asbestos related diseases.should be specified and should be
1
' uniformly followed. (Para 14.2 of Report by Study rTeam `B'). Criteria for diagnosis for
asbestosis is included in this report for the purpose of determining eligibility for compensa
te
tion (pani 24.1.6 of Report bo Study T eam `A'). Criteria for confirming asbestos as caus-
:
ative factor for lung cancer and mesothelioma is also included in.this repo-t for the purpose
off
of determining eligibility for compensation. (Paras 25.7 and 26.8 of Report by Study
or'
T eam `A)'.
7 3 The Committee recognises the need to designate an agency that possesses specialised training,
,() j
' expertise, competence and facilities to decide the cases entitled to compensation arising out
j .
of asbestos-related diseases. (Para 16.12 of Report by Study Team *B').
;
7 4 Regional medical panels should be constituted to act as referal bodies in case of asbeslos-
.(1| ;
related diseases to determine eligibility for compensation. (Para 34 of Report by Study
^
Team `A').
7 5 Panel should have specialists, preferably with knowledge of asbestos-related diseases. (Para
.
34 of Repoit by Study Team `A').
