Lead exposure, defensibly measured.

Personal air monitoring and surface wipe sampling for lead — evaluated against the WorkSafe Workplace Exposure Standard and AS/NZS 4361.2:2017. The data your safety case, your insurer or your regulator will accept.

Lead exposure monitoring & site investigations

Lead hazards remain relevant across many New Zealand workplaces — particularly construction, demolition, radiator repair, and battery recycling. Lead paint is also commonly found in pre-1980s residential and commercial buildings, presenting risks during renovation or demolition works.

Sampling is conducted by a MAIOH-qualified occupational hygienist using calibrated personal sampling pumps, validated cassettes, and AS/NZS 4361-aligned wipe protocols. Analytical work is processed through IANZ-accredited partner laboratories with chain of custody preserved end-to-end.

When to request a lead assessment

Lead assessment is appropriate before pre-1980s renovation or demolition; in any workplace where lead-containing materials are cut, sanded, welded or recycled; for baseline exposure monitoring; or to validate post-decontamination clearance after a known release.
