IS 11769 Part 2 addresses asbestos-containing friction materials in moulded and woven forms utilized in automotive and industrial braking and clutch systems, including brake linings (roll, strip, sheet), brake blocks, liners, disc brake pads, clutch facings, transmission discs, and band liners. The section outlines the objective to promote safe assembly, usage, and servicing to reduce asbestos dust release, with references to associated standards found in Annex A. Key specifications summarize material types, forms, and applications, emphasizing safety measures during handling and operations.
This section lists essential Indian Standards integral to the safe use of asbestos friction materials, including IS 11767 (cleaning of asbestos-containing premises), IS 11768 (asbestos waste disposal), and IS 12081 Part 2 (pictorial warning signs for asbestos products). It highlights critical points such as waste disposal procedures, packaging warnings, and material safety data sheet requirements, reinforcing compliance through structured safety protocols.
Defines key terms related to asbestos-containing friction materials, covering various product forms such as brake linings, blocks, pads, and clutch facings. It clarifies the scope for safe handling and emission control of asbestos dust during manufacturing and maintenance activities, with a focus on moulded and woven materials.
Details essential safety measures including mandatory use of dust extraction systems at fixed workstations, maintenance of airborne fiber concentrations below specified thresholds, and personal protective equipment usage. It discourages dry sanding and promotes wet methods and vacuum extraction to control dust, alongside proper waste disposal as per environmental standards.
Specifies that friction materials should be supplied ready for application without additional finishing. When finishing is unavoidable, only hand tools are permitted unless power tools are used with exhaust ventilation to prevent asbestos dust release. The section underscores adherence to referenced standards for safe application and servicing.
Addresses safety protocols during brake and clutch servicing involving asbestos materials. It mandates daily inspection and testing of exhaust ventilation systems, restricted finishing operations with appropriate tooling, and emphasizes ventilation to minimize asbestos fiber exposure, with record-keeping for inspection results.
Outlines procedures for handling and disposing asbestos waste such as broken linings, loose swarf, and dust. It mandates collection in impermeable bags, wetting of waste if vacuum cleaning is unavailable, and disposal as per IS 11768. Packaging must display pictorial warnings in compliance with IS 12081 Part 2, and Material Safety Data Sheets should accompany products to guide safe handling and disposal.
Describes packaging standards requiring sealed, dust-tight containers with clear pictorial warnings and precautionary notices per IS 12081 Part 2. Labeling must include product identification, manufacturer details, health hazard warnings, handling instructions, and disposal guidelines. Material Safety Data Sheets are essential for conveying these details to ensure safe handling and regulatory compliance.
Specifies the essential contents of Material Safety Data Sheets for asbestos friction materials, including product designation, manufacturer information, health hazard descriptions, handling precautions, and waste disposal instructions. It ensures informed and safe handling practices aligned with referenced standards.
Compiles key Indian Standards related to asbestos friction materials, including IS 11767 for cleaning asbestos fiber-contaminated sites, IS 11768 for asbestos waste disposal, and IS 12081 Part 2 for warning signage. These standards collectively support safe handling, environmental compliance, and health protection.
Frequently Asked
IS 11769 Part 2 applies to asbestos-containing friction products used in braking and clutch systems, including moulded and woven brake linings (roll, strip, sheet), brake blocks, liners, disc brake pads, clutch facings, automotive transmission discs, band liners, and industrial brake and clutch linings. It provides safety guidelines to minimize asbestos dust exposure during use and maintenance.
The standard mandates dust extraction apparatus for all cutting, drilling, or grinding machines to capture asbestos dust effectively. Fixed machines must have continuous dust extraction with adequate air flow to keep airborne fiber levels below limits. Portable tools should be equipped with high velocity, low volume dust extraction, and exhaust ventilation must be used during machining operations to control dust generated during finishing and cleaning.
Waste such as broken or worn linings and loose dust must be collected carefully to minimize dust release. Disposal must follow IS 11768 guidelines, ensuring controlled handling. Waste should be packaged in strong impermeable bags labeled with pictorial asbestos warnings as per IS 12081 Part 2. Procedures outlined in Material Safety Data Sheets for cleaning and disposal must be strictly followed to protect health and the environment.
Packaging must be sealed and dust-tight to prevent asbestos fiber release and bear pictorial warning signs and precautionary notices conforming to IS 12081 Part 2. Labels should clearly state the presence of asbestos, include health hazard warnings, product type, manufacturer details, and safe handling and disposal instructions. Material Safety Data Sheets must accompany products to provide comprehensive safety information.
Vacuum cleaning with appropriate equipment designed for asbestos dust is the preferred method to safely remove dust and debris. If vacuum cleaning is not feasible, dust and swarf must be thoroughly wetted prior to removal to prevent fibers from becoming airborne. Fixed equipment generating dust must use effective dust extraction systems maintained below threshold fiber concentrations to ensure worker safety.
