Heat guns and sanders on pre-1980 paint
Lead-based paint was in common New Zealand use for decades. Heating and abrasive removal are the methods that turn a stable coating into an inhalable and ingestible exposure.
Surface preparation is where the exposure happens — not the painting. Lead on pre-1980 substrates, solvent vapour in unventilated interiors, and the access method that puts most painters at height for the whole job.

Painting reads as a low-risk trade and is not one. The health exposures are chronic rather than acute, which is exactly why they are under-controlled: lead from preparing old substrates, isocyanates and solvents from two-pack and spray systems, and organic vapour accumulating in interiors with the windows shut because the client wants the doors closed. Layered on top is that most painting is done at height for most of the day. This JSA treats preparation as the hazardous phase, because it is.

Vapour accumulates in a closed room and does not announce itself. The template requires ventilation to be planned rather than improvised.
Painting from a ladder for an entire exterior is normal and it is also why painters fall. The access decision belongs at the top of the analysis, not as an afterthought.
If your painting SSSP is what a main contractor has asked for, that is the project-level document — this sits underneath it.

A Job Safety Analysis is not a named statutory document in New Zealand — unlike an Australian SWMS, no regulation requires one by that name. Its weight comes from the duties it discharges, and from the fact that main contractors and prequalification schemes treat it as the expected evidence that a high-risk task was thought through before it started.
The most common alternative in New Zealand is an Australian SWMS with the branding changed. It is worth being precise about why that is a problem.
Written and reviewed by the occupational health and safety team at OH Consultant. These are drafted as New Zealand Job Safety Analyses, not as Australian SWMS with the terminology swapped. That distinction is substantive: a SWMS is an instrument created by Australian WHS regulation for high-risk construction work, with prescribed content and a statutory trigger. New Zealand has no equivalent provision, so a document presented as a "NZ SWMS" is citing a requirement that does not exist here.
