1-Bromopropane<\/strong> (n-propyl bromide or nPB) is a new WEL substance: 0.5 mg\/m\u00b3 (0.1 ppm)<\/strong> as an 8-hour TWA. WES remains the reference until 30 November 2026; WEL applies from 1 December 2026 once implemented. Check your WHS regulator.<\/p>\n Name 1-bromopropane and nPB on the hazardous chemical register. Map degrease, wipe, spray, maintenance, lab, waste and contractor SEGs. Check SDS, permits, emergency procedures, historical monitoring and who owns elimination or enclosure. Job titles alone are not a SEG.<\/p>\n Prefer aqueous or closed alternatives. Enclose degreasers; maintain freeboard, cooling, seals, condensers and exhaust; use LEV at wipe\/spray points; minimise open time and plan sludge\/filter work. Select compatible gloves and fit-tested organic-vapour RPE with cartridge-change rules last. Do not treat odour as a measuring instrument or invent a STEL.<\/p>\n Baseline representative full-shift personal exposure against 0.5 mg\/m\u00b3 (0.1 ppm), including load\/unload, aerosol\/wipe and maintenance tasks. Agree analyte-specific media and report both units where supported. Generic VOC badges only answer this WEL if validated for 1-bromopropane.<\/p>\n Safe Work Australia WEL changes<\/a> \u00b7 SWA WEL\/WES changes<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Why this number matters 1-Bromopropane (n-propyl bromide or nPB) is a new WEL substance: 0.5 mg\/m\u00b3 (0.1 ppm) as an 8-hour TWA.
