17th March, 2006
Introduction
A national seminar on “Hazards of Asbestos and Silica in Construction Industry” was organised by DGFASLI, Government of India, Ministry of Labour & Employment on 17th March, 2006. The Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act 1996 is administered in the Central Sector by the DGLW and CLC. The Act is also being notified by the State Governments. The construction industry employs a large workforce and majority of them are illiterate. This seminar was aimed at sensitizing the Labour Secretaries and Enforcement Officials about the hazards existing in the construction sector.
Mr. S.K. Saxena, Director General, DGFASLI. Mr. Saxena welcomed the dignitaries to the seminar.
Giving the background about the seminar he said “The Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act, 1996” is administered in the central sector by DGLW & CLC. Concern was shown to look into the implementation of this Act for which a committee was formed with Secretary(Labour) as its Chairman. In one of the meetings it was mentioned by the delegate states that there is need to sensitize the Enforcement Officers, Labour Secretaries on the legal as well as technical aspects of the Act and there it was suggested that DGFASLI should be asked to organize a seminar. The seminar was held on 27th January, 2006. In this seminar Secretary (Labour), Director General, Labour Welfare and the labour secretaries of the states were present. All the delegates in the seminar were of the view that there is a need to sensitize the Enforcement Officers on occupational safety and health. In this seminar the Secretary (Labour) directed DGFASLI to organize a seminar to look into the hazards involved in the use of asbestos in construction industry. It was suggested by DGFASLI that it would be worth including hazards due to silica dust also. Hence this seminar on “Hazards Of Asbestos And Silica In Construction Industry” is being organised. There is a need for training the enforcement officials. DGFASLI is prepared to provide any assistance in the implementation of the Act. He further added that the construction activity is going on for ages, however we were not aware of the hazards involved. But now the situation is different. This seminar aims to look into the hazards in construction industry and what measures should be taken and strategies adopted for the years to come.
He said that the seminar was divided into 3 parts. In the first part we would look into the use of asbestos in construction industry in which representatives from Asbestos Contained Product Manufacturing Industries Association would be the speaker. The second part will be on hazards associated with the use of silica and the third part would be summarization wherein the strategies for abatement of these hazards would be discussed. He welcomed all the participants to the seminar and requested them to have good interaction with the resource persons and other delegates.
The first session was chaired by Dr. H.N. Saiyed, Director, NIOH
He said “First of all let me thank DGFASLI, the organizer of the seminar for inviting me to the chair the technical session. Construction industry is a very important industry where a large number of people are employed and asbestos is one of the concern”. He requested the first speaker from the industry to give his speech on “Asbestos in Construction Industry”.
Paper I :
“Use of Asbestos in Construction Industry”
Dr. S.P. Vivek Chandra Rao, General Manager, Occ. Health and Environment, Hyderabad Industries Ltd. made the presentation. Giving the various end uses of asbestos he said asbestos is used in manufacturing of more than 3000 products. In India 90% of white (Chrysotile) fiber is used in the manufacture of asbestos cement product with the composition of 8 to 9% of fiber, 30% fly ash, 41% cement and 20% water. He said there is a growth in the cement products at the rate of 15 to 20% every year. Regarding the work environment in the asbestos products manufacturing industry he said the concentration of dust level based on the study conducted by DGFASLI in 2004 and 2005 is between 0.003 to 0.13 f/cc in asbestos cement sheet plants, between 0.13 to 1.28 f/cc in asbestos cement pipe units and between 0.12 to 0.68 f/cc in asbestos mill board unit. Giving scientific evidence to support the DGFASLI study, he made a mention of the report of the Royal Commission on matters of health and safety arising from use of asbestos in Ontario – Volume I, page 129, 281 which says “In our judgement, asbestosis can be deemed a disease of past high exposure levels and will not occur in workers exposed to the regulated levels of occupational exposure now in force in Ontario (3 f/cc adapted in 1973)”. He said, similarly in the International Symposium on Health Effects of Low Exposures to Fibrous Materials 1991, ICOH, Dr. Manfred Neuberger, Austria had said that the present standards for Chrysotile (0.1-1.0 f/ml) prevent asbestosis and all chrysotile related cancers with high thresholds than asbestosis. In mining, asbestos cement and friction products manufacturing the mesothelioma risk is negligible if no amphiboles are used. And again in the EHC 203 “Chrysotile Asbestos” – 1998 IPSC (UNEP, ILO, WHO) has stated that regarding effects on humans the summary quotes that Asbestotic changes are common following prolonged exposures of 5 – 20 f/ml. This sort of workplace exposures were seen prior to 1975 hence these levels may be responsible for asbestos related diseases till 2025. Regarding lung cancer, the summary describes that the overall relative risks are generally not alleviated in the studies of workers in asbestos cement production and in some of the cohorts of asbestos cement production workers. He further brought out some features of chemical composition of asbestos and its biopersistence. He said the longer the biopersistence the greater is the risk for adverse health effects to become visible. He said asbestos was used in construction industry in industrial buildings of all types, food storage godowns, warehouses and cold storage godowns, poultry farms, dairy farms, houses, garages, school buildings, public utility sheds, cooling towers, railways and bus stops and in coastal & hilly areas for houses, etc. He explained the correct method and proper usage of tools while working with asbestos cement products in the construction industry. He also put forward the dust levels measured while working with asbestos cement sheets using hand driven tools and this was found to be less than 0.1 f/ml for 40 minutes working. Giving a reference of a study conducted by Dr. J. Baeten and Dr. J. Helsen, Department of Meteorology Catholieke University, Belgium regarding the total dust produced by machining operation of asbestos cement products, it was observed that in asbestos-cement dust most of the asbestos fibres form aggregates with cement particles that are larger that the fibre diameter and those which do not form aggregates i.e. optically pure fibres appear to be coated with calcium containing layer. These fibres behave differently from pure asbestos as regards movement and settlement in fluids. Their physio-chemical behaviour may also be different therefore conclusions which have been reached for pure asbestos dust should not be automatically applied to asbestos-cement-dust. He also gave an account of the average calculated fibre concentration and compared characteristics of various roofing materials highlighting the advantages of asbestos sheets. In the conclusion, he said that the construction workers engaged in sawing, drilling and laying of asbestos cement sheets and following recommended work practices are exposed to asbestos cement dust and the concentration is less than 0.1 f/cc of air. At such levels, there should not be any chrysotile asbestos related disease in construction workers. He thanked DGFASLI and the Ministry of Labour & Employment for giving him the opportunity for presenting this paper.
Paper II :
“Health Hazards of Asbestos”
Chairman then invited Dr. T.V. Ranga Rao, Director (Med.), CLI to make his presentation. Dr. Ranga Rao began his presentation with the display of different type of asbestos as existing in its natural form . He said that the asbestos fibre could enter human body through inhalation and ingestion and the exposure to asbestos fibre could be occupational, para-occupational and non-occupational. He explained the mechanism action of exposure. The inhaled airborne fibres of less than 3 µm diameter penetrated the airways and it retained in the lungs. Short fibres are engulfed by macrophages and carried to the lymph nodes. Small air ways and alveoli coated with iron protein complex becomes asbestosis of Ferruginous bodies. Long time retention leads to diffused pulmonary fibrosis with pleural fibrosis. After 20-40 years of exposure one may develop lung cancer, malignant mesothelieoma or gastro intestinal cancer. The health effects of asbestos include benign pleural effusion, pleural scarring, pulmonary fibrosis (asbestosis), rounded atelectasis, lung cancer, mesothelioma, Ca-GI tract, larynx, etc. Dr. Rao also demonstrated the asbestos related diseases with the help of X-rays and microscopic pictures. He also demonstrated the use of asbestos in construction industry with the help of slides and pictures. He said that in construction industry the Threshold Limit Value (TLV) of asbestos cement product is 0.1 f/cc and the Permissible Exposure Limit (PEL) of Chrysotile is 1.0 f/cc. Concluding his presentation Dr. Rao said that the asbestos was a known enemy and is to be used in controlled conditions.
Paper III : “Safety in Use, Handling and Disposal of
Asbestos Products in
Construction
Industry”
Dr. P.K. Sishodiya, Deputy Director of Mines Safety (OH), Occupational Health Division, DGMS, Ministry of Labour & Employment in his presentation highlighted various types of products of asbestos used in construction industry such as asbestos cement sheets, asbestos cement pipes, asbestos tiles and other roofing material and prefab panels, boards and jointing. He said the important properties of asbestos product were high density, non-friable, containing 3 to 10 percent of chrysotile asbestos. The asbestos fibre are locked in matrix and they contain cement fly-ash and other materials. He said the asbestos products had many advantages such as it is relatively cheaper, durable, heat resistant, easy to install and corrosion resistance. The common operations in use of asbestos products are stacking, sawing, drilling, cutting, grinding, filing, cleaning and nailing. The possible health hazards because of these operations would be inhalation of fibres as significant amount of airborne asbestos fibre dust can be generated during any of the operations if proper precautions are not taken. He explained the general precautions to be taken while using asbestos cement products. This include using mechanical handling when large quantities of product is to be handled, carefully placing products in stacks, during manual handling avoiding sliding the product against abrasive surface, avoiding dragging and dropping of the products, maintaining designated storage area clean and disposing of damaged and crushed products in appropriate manner. He demonstrated the use of manual hand tools on asbestos products. As a general guidelines for tools he said for cutting, handsaw, nibblers and low speed circular cutters should be used. For drilling, hand drills or power drills with local exhaust can be employed and for sanding power operated sanders with local exhaust should be used and for cut outs hand saw, jig saw and low speed circular cutters should be used. He said, as far as possible high powered tools should be avoided. He said it was obligatory for the manufacturers of asbestos products to put a mark on the product indicating that it contains asbestos to supply safety data sheet and provide information to the end user on proper use of asbestos product. He said the asbestos product with specific pictograms and warning phrases in common man’s language should be placed on asbestos products. He further listed important Indian standards viz. IS:11766-1986, recommendations for disposal of asbestos waste material, IS:11769(part 1)-1987, guidelines for safe use of products containing asbestos: part 1, asbestos cement products, IS:11769(part 2)-1986, guidelines for safe use of products containing asbestos : part 2, friction materials, IS:11769 (part 3) -1986, guidelines for safe use of products containing asbestos : part 3, non-cement asbestos product other than friction materials, IS:12079-1987, recommendations for packaging, transport and storage of asbestos and IS:12081(part 2) – 1987 recommendations for pictorial warning signs and precautionary notices for asbestos and products containing asbestos part 2, asbestos and its products. Further he highlighted the precautions to be taken while using asbestos products. He said that the operations should be carried out in well ventilated areas, the product should be damped before cutting or drilling, hand tools should be used which produces coarse and non-respirable dust, high powered tools and stationery cutting equipment must be fitted with local exhaust and dust generated should be properly disposal off. Regarding waste handling and its disposal he said that the waste should be handled in such a manner that it does not pose a health risk and waste containing high density products should be disposed off in land fills and covered with soil. This disposal sites should be identified and should have vehicular access. The waste should be deposited at the bottom of the land fill. All wastes, except high density waste should be covered with 250 mm of soil. The final covering of the soil should be atleast 2 meters. Wet waste should also be covered with soil. The asbestos disposal site should be clearly marked and public access should be minimum. The high density waste can be disposed off as normal waste but the final covering should be 2 meters of soil. Dr. Sishodiya, concluded his presentation with a thanks to the Ministry of Labour & Employment and DGFASLI.
The chairman Dr. H.N. Saiyed, Director NIOH while summarizing the first session said that Dr. V.K. Rao talked about the two forms of asbestos and their properties. Each asbestos has got different properties. 90% asbestos used in our country are Chrysotile asbestos. In the studies conducted by DGFASLI very recently in 2005 there are no cases of asbestos related diseases detected in industry.
Dr. Rangao Rao has made his presentation with good pictorial and graphic slides giving the details about the asbestos and its occupational hazards.
The third speaker Dr. P.K. Sishodiya also had the same thought. He gave us the Indian Standards which are used as guidelines for use in industry handling asbestos.
The second session was chaired by Mr. S.K. Saxena, Director General, DGFASLI. Three papers were presented in this session.
Paper I :
“Health Hazard in Handling and Use of Silica Products”
This paper was presented by Dr. H.N. Saiyed, Director, NIOH, Ahmedabad. The overview of the presentation included the general characteristics of silica dust, pathogenesis of silicosis, long term effects of silica exposure, sources of exposure in construction industry and prevention and control of silica exposure in construction industry. Dr. Saiyed said that silica has universal presence and crystalline silica or quartz is the most wide spread fibrogenic substance found in nature. 28% of earth’s crust is silica. He said, silica is non-irritant and does not produce any perceivable immediate effect. Therefore large amount of silica dust may be inhaled by the workers the consequences of which would be seen only at later stage. He said, the permissible level as per the section 41(f) of Factories Act 1948 for free silica is 0.1 mg/m3 as compared to benzene 20 mg/m3 and carbon monoxide 40 mg/m3. He explained the defence mechanism of the respiratory system. The first line included filtration, impaction and sedimentation. The second line of defense is clearance and includes conducting airways – mucocilliary system and gas exchange region – Alveolar fluid and Alveolar macrophage. Through microscopic photographs and graphical presentations he explained the phagocytosis of quartz and death of macrophages. Regarding long term health effects of silica inhalation he said it can lead to irreversible and progressive fibrosis of lung silicosis, increase susceptibility to tuberculosis, chronic bronchitis, immunological diseases, kidney diseases and lung cancer. He said that there are various factors which affect the onset of silicosis such as amount of dust inhaled, percentage of free or uncombined silica in the dust, the size of dust particles and the length of exposure. Silicosis is of 3 types – simple, accelerated and acute. He said that in construction industry the hazards of silicosis existed in stone crushers (road construction), handlers of sand, silica contaminants from various materials used in construction and underground construction work such tunneling, laying pipes, etc.
Regarding prevention of silica dust exposure, he said that it was necessary to monitor the exposure, reduce the duration of exposure by administrative control, reduce exposure concentration by engineering controls at the source, environmental control and provide PPE to the workers. Worker’s education and awareness programme will also help in prevention of exposure and have medical controls through medical surveillance programs. Dr. Saiyed concluded his presentation saying that the silicosis is a progressive and potential fatal but preventable disease. Therefore all efforts should be made for its prevention.
Paper II : “Safety and Health and Handling and Use of
Construction Materials
Containing Free Silica”
Mr. M.R. Rajput, Deputy Director, Regional Labour Institute, Chennai started his presentation by giving a brief background about the construction industry in terms of the employment and the statutory provisions available in the country. He also highlighted various sections of the Building & Construction Workers (Regulation of Employment & Conditions of Service) Act 1996 and also the ILO Code of Practice on Safety and Health in Building and Civil Engineering Works 1982. He said that the construction material which contain free silica are cement, concrete, sand and fly ash. In cement the quartz content is usually below 1%. The threshold limit of cement dust is 10 mg/m3 and the dust concentration observed in the work environment was between 7 to 19 mg/m3. The cement dust is irritant to eyes and causes dermatitis and case of pneumoconiosis, bronchitis, emphysema, etc. have been reported. For cement dust, the remedial measures suggested include proper and regular maintenance of all the dust control equipments, prohibiting the use of hooks while manual handling of cement bags, effective use of dust respirators among the workers, and regular medical examination of the workers.
As regard to the sand, it contains free silica between 19 to 78% depending upon the quality and nature of the stones and location of source. The inhalation of dust causes silicosis. The permissible level of exposure (PLE) based on silica content is 30 / % quartz + 3 mg/m3. The stone crushing units where the study was made by DGFASLI are located in UP, MP, Haryana, AP, Kerala, Karnataka, Tamil Nadu, etc. The stone boulders are manually broken by the workers and small size stones are crushed in crushers to produce concrete and sand. The handling of concrete and powder sand leads to exposure to silica dust. In some of the units, water spray was used while handling concrete and powder sand. The airborne dust levels range from 28.5 to 138 mg/m3 which exceeds the PLE. In the units where water spray arrangement was present, the air borne dust levels were found to be in the range of 9.5 to 19.5 mg/m3. Mr. Rajput said that the remedial measures suggested for controlling dust in work environment were rotary screeners/vibrator to be covered to the maximum extent so as to reduce dust emission. Water spray arrangement should be made mandatory while stone crushing is in progress. Workers should be provided with suitable disposable type dust respirator and workers should be medical examined at regular intervals.
Mr. Rajput further talked about the fly ash which is incombustible residue left after the burning of coal in thermal power plants. The fly ash is used in the manufacturing of cement, building blocks, etc. The fly ash contains 10 – 20% of free silica as such inhalation may cause silicosis. The studies conducted by DGFASLI have indicated the airborne contaminants in the level of 3.4 to 24 mg/m3 which exceeds the PLE of 1.7 mg/m3. As remedial measure the fly ash godown should have system of sprinkling of water before handling fly ash. House keeping in fly ash godowns should be improved and fine powder accumulated on the floor should be promptly collected and re-used and the workers should be provided with the dust mask. Mr. Rajput supplemented his presentation with pictures and graphs from the stone crushing industry. He concluded his presentation with a thanks to DGFASLI.
Paper III : “Safe Work
Practices in Handling and Use of Construction Material
Containing Free Silica”
Mr. Biprajit Chakravarty, Vice President (Safety & Environment) from Associated Cement Companies Ltd. started his presentation with a thanks to the Ministry of Labour & Employment and DGFASLI for giving him the opportunity to present his paper. He said that the workers were exposed to silica while carrying out sand blasting , rock drilling, jack hammering, tunneling and mining in construction industry; grinding and molding in foundry work, ceramics, clay and pottery, stone cutting, chipping and grinding, glass manufacturing, agriculture and abrasive blasting and ship breaking. The most severe exposures to silica have occurred during the abrasive blasting with stand to remove paint and rust from bridges, tanks, concrete structures and other surfaces. He said that the crystalline silica is natural constituent of earth crust and is a basic component of sand and granite. The impact of exposure to crystalline silica causes chronic silicosis which occurs after 15 to 20 years of moderate to low exposures to respirable crystalline silica. Accelerated silicosis can occur after 5 to 10 years of high exposure to respirable crystalline silica and acute silicosis occurs after a few months of exposures to extremely high concentration of crystalline silica and more importantly there is no cure for silicosis.
He brought out the list of building materials which contain free silica namely blasting abrasives, brick, concrete and cement mortar, granite, sand stone, slate, rock, mineral deposits, sand, soil and asphalt. Regarding the safe work practices he said that all crystalline silica materials may be replaced, engineering controls may be provided, the exposure levels should be reduced below the PEL, personal protective equipment should be used, water sprays should be used to control the dust, workers should be trained and health screening and monitoring should be carried out. He further added that one should identify the tasks which contribute to crystalline silica exposures, know how to protect one self, know the hazard of crystalline silica exposures, do not eat, drink and smoke where silica dust is present and wash hands and face outside the dusty area.
Explaining the controls of silica in construction industry, he said the engineering controls include using local exhaust ventilation and collection, using wet method and protecting operator from silica exposure, the administrative controls include job rotation of workers so that there is no continuous exposure. For controlling the hazards of silica, proper house keeping should be followed so that the exposed surfaces are free from accumulation of silica, prohibit dry sweeping and use compressed air for cleaning of surfaces, properly filter vacuumed exhaust air and gentle washing is preferable. He said, training of employees was very important in the control of silica hazards in construction industry. The employees should be trained in safe practices, health effects, use of personal protective equipments and also they should be provided with information related to adverse health effects of crystalline silica and also information on material safety data sheets etc.
The work environment needs to be monitored continuously so that corrective actions can be taken in case the levels exceed above the PEL. Medical surveillance programmes should be carried out regularly in order to monitor the workers health. He also explained hazard information which can be disseminated to all the persons working with free silica. He ended the presentation with a thanks to the organisers.
The panel discussion was chaired by Mr. S.K. Saxena, Director General, DGFASLI. The discussion started with all the delegates agreeing to the fact that the Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act 1996 was very clear and at the same time very technical in nature. Hence it is necessary to clearly identify who would enforce the legislations in various states. Mr. M.N. Siddiqui was of the opinion that it should be the Directorate of Factories in the State Governments with DGFASLI monitoring it centrally as well as enforcing it in the Central Sector. It was suggested that the welfare aspect of the Act can be taken care by the Labour Commissioner’s department and the working conditions aspect can be taken care by the Directorate of Factories and DGFASLI at the State Government and the Central Government level respectively.
There is a need for a system of rating of the registered establishments based on their safety and health performance. Once a company is rated the same would be reviewed annually. As such a panel of all the registered construction establishments could be created with a unique rating. The rating would immediately identify the standing of a company with respect to its safety and health performance. This in turn would become a criteria for determining the frequency of inspections : An organization having higher rating could be allowed inspection free periods, while organisations with lower ratings would have to be inspected frequently. Also for tendering purposes, the rating could be made a compulsory criteria for eligibility. However, this rating has to be done at the Central level on an all India basis, to avoid duplication, and the mechanism could be undertaken by DGFASLI.
Dr. V.C. Rao suggested that the manufacturers especially of asbestos cement products should take up the responsibility of explaining to the end users the safe work practices and operating procedures when they sell the product. Here the chairman added that the safe work practices should be explained to the workers and the employer should be held responsible for implementation of the safe work practices.
The threshold limit value (TLV) for asbestos and silica were also discussed and it was decided that the TLV for asbestos and silica for construction industry can be the same as that recommended in the Factories Act. As regard to silica, it was discussed that in construction industry the hazards due to free silica is more and indepth study is required to be carried out. Dr. P.K. Shisodiya said that a lot of work needs to be done as the active silica can cause acute silicosis.
After the discussions the chairman asked the delegates to discuss about the strategies to be adopted for the construction industry. The seminar unanimously decided to adopt the following recommendations and strategies :
1. The use of mask was deliberated and it was emphasized that it should be used as a last resort. It is important to control the work environment so that the asbestos fibres are in the permissible limits. However, when the work is of shorter intervals, proper masks can be used. Simple cotton mask will not serve any purpose. Therefore only proper mask made of fibres which are 98.6% efficient can be used.
2. The TLV for construction industry was debated and it was suggested that it should be same as given in Factories Act.
3. The construction company should employ medical officer with a requisite qualification of AFIH to carry out medical surveillance of workers at regular intervals.
4. A system of having licensed/accredited contractors having specialization in different areas such as handling and disposal of asbestos, etc. should be devised . This would help in ensuring and implementing safe work practices in the industry.
5. The workers should be trained in various aspects of safety and health. For this purpose specific training modules can be developed in local languages so that the workers can understand and follow safe operating procedures and work practices.
6. The Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act 1996 is very technical in nature specially the provisions relating to safety and health. Therefore it was felt that the implementation of the Act should be with agencies/organisations having occupational safety and health background.
7. In the above Act, the welfare aspect can be enforced by the Labour Commissioners where as the safety and health aspect can be enforced by DGFASLI in central sector and Chief Inspector of Factories in states.
8. The employer should be made responsible for implementation of safe work practices.
9. It is necessary to organize awareness campaigns and disseminate information relating to good practices, do’s and don’ts, hazards, etc. in the construction industry through various media.
10. Competent persons can be declared by a central agency such as DGFASLI and complete work pertaining to it i.e. upto the signing of the competency order should be handled by them so that unnecessary delays are not caused and effectiveness is brought in. This practice is followed under Dock Safety Statutes.
11. These competent persons should be accepted under the state sector also in addition to the ones that are declared by the respective State Governments
The seminar ended with a vote of thanks to all the delegates and their organizations for their active participation in the seminar.
