Occupational Safety, Health and Environmental Practices in Textile Work
What this domain tests
Safety and environment questions test hazard recognition, safe practice, and legal or voluntary compliance in dyeing, printing and embellishment workshops.
Core rules
- Chemical hazards: dyes and mordants can be sensitisers; some azo dyes release carcinogenic amines; formaldehyde and heavy metals are restricted; solvents can cause respiratory and neurological effects. Keep and read the MSDS or SDS.
- Engineering controls come first: local exhaust ventilation, enclosed mixing, bunded storage and spill kits. Then administrative controls and PPE (gloves, goggles, apron, respirator).
- Never mix bleach with acid (chlorine gas) or oxidisers with reducers. Store chemicals by compatibility, labelled and off the floor.
- Ergonomics: adjustable tables, anti-fatigue mats and micro-breaks for embroiderers and tailors; electrical safety and fire extinguishers in dry areas.
- Environment: treat effluent, recycle rinse water, use low-impact dyes, and choose GOTS, OEKO-TEX Standard 100 or ZDHC-compliant inputs. Reduce, reuse and recycle fabric waste.
Worked example
A screen-printing table uses solvent-based ink in a small room. The safer plan is to switch to water-based ink, add local exhaust at the squeegee, wear nitrile gloves and goggles, store ink in a closed cabinet, and dispose of wash water through an effluent line-not the drain. Reasoning: substitution removes the hazard at source; ventilation controls the remaining vapour; PPE is the last line of defence.
Traps
Assuming natural dyes are automatically safe (mordants can be toxic); wearing cloth gloves for solvents; storing acid and bleach together; pouring dye liquor into open drains; ignoring noise and repetitive strain in embellishment units.
