Overview - ISO 11111-5:2005 (Textile machinery safety for preparatory machinery)
ISO 11111-5:2005 is the International Standard that specifies significant hazards and corresponding safety requirements for preparatory machinery to weaving and knitting. Intended to be used together with ISO 11111-1:2005 (Common requirements), this part covers machinery and plant used for warping, beaming, sizing, size preparation and storage of warp and cloth beams. It is a type C standard (machine-sector specific) and is aimed at reducing mechanical, electrical, thermal and other risks associated with preparatory textile equipment.
Key topics and technical requirements
- Scope of machinery covered: cone/sectional/beam warping machines, beaming and assembly beaming machines, sizing machines (including cylinder dryers and size baths), size kettles and storage equipment for warp beams.
- Hazard identification: mechanical entanglement, drawing-in/trapping by rollers or beams, beam ejection, falls from beam-clamping failure, thermal hazards from dryers, dust and noise emissions.
- Protective measures and guarding:
- Physical guards and interlocked movable guards for drawing-in points and headstock rollers.
- Active opto-electronic protective devices (AOPD) and trip bars for beam warping machines where appropriate.
- Interlocked elevating platforms and enclosure/cabinet guarding for dryers.
- Operational controls:
- Machine movement restricted to crawl speed or hand rotation when guards/safety devices are made inactive; hold-to-run controls for special operations.
- For cylinder dryers, access doors must be interlocked or permit only hold-to-run control from a clearly positioned control (portable or fixed) with fail-safe wiring or compliant cableless controls.
- Specific device requirements: beam-clamping systems designed to retain beams in the event of pressure loss; cone blade covers to prevent entanglement.
- Other safety aspects: electrical equipment and control systems, fluid power safety, noise, dust/fly emission control, hot surfaces, ergonomics, escape/rescue, verification and documentation in instruction handbooks.
Practical applications and benefits
- Use ISO 11111-5:2005 when designing, manufacturing, retrofitting or installing preparatory textile machinery to ensure compliance with recognized textile machinery safety practices.
- Helps reduce workplace injuries from entanglement, crushing, thermal burns and falls; provides guidance for machine safeguarding, control layout and operator procedures.
- Supports machine risk assessment and verification activities, and informs operator manuals and maintenance procedures.
Who should use this standard
- Textile machinery designers and manufacturers
- Systems integrators and plant installers
- Health & safety professionals, conformity assessors and certification bodies
- Textile mill managers, operators and maintenance teams
