What you get
One editable Word document covering wet area waterproofing for Tiling & Waterproofing: the task broken into steps, the hazards at each step, the controls, and a 5 by 5 risk matrix with residual ratings. Site fields and a crew sign-on are built in.
A Task Analysis is also known as a JSA (Job Safety Analysis) or JSEA. It covers each step of the job, the hazards and the controls.
The steps and hazards it covers
| Step | Hazards |
|---|---|
| Plan, prepare and confirm competency | Workers without the required training, competence or authorisation performing the task - incidents arising from lack of skill, competency or authorityDefective or unsafe plant, powered equipment, leads or attachments failing in useWorking on other people's sites, occupied premises or around the public |
| Prepare the substrate | Dust from grinding and edge preparation, including possible asbestos in old sheet |
| Apply solvent-based membranes and primers | Vapour ignition and intoxication from solvent membranes in small unventilated bathroomsVapour accumulation and heat in small sealed rooms |
| Handle membranes, primers and polyurethanes safely | Dermatitis and sensitisation from membranes, primers and polyurethanesCuts from scrapers and knives detailing angles and corners |
| Apply membrane while kneeling in confined wet areas | Knee and back strain working in cramped wet areas |
| Flood test and protect the membrane | Water escape damaging the building and slips on test waterTrades walking on curing membrane causing system failure and rework |
| Clean up, demobilise and dispose of waste | Solvent rags self-igniting and membrane waste |
Each hazard comes with its control measures, an initial and residual risk rating and the person responsible, ready to check against your job.
How to use it
Read it against the actual job. Delete the hazards that are not there, add the ones that are, fill the site fields, then brief the crew and get every name on the sign-on. A document nobody has read is a piece of paper. One the crew helped finish supports worker consultation and records the agreed work method. Engagement under HSWA ss58 to 59 is an ongoing process of seeking and considering workers’ views, so the signed page is evidence of part of it rather than the whole duty.

Where it sits in the law
New Zealand does not require a document of this name. The duty is to manage risk so far as is reasonably practicable (HSWA s36) and to engage workers on it (ss58 to 59). Use a Task Analysis to plan the work, identify the hazards and communicate the controls to your crew. That is also how you evidence both duties.
WorkSafe names “a task analysis, safe work method statement (SWMS), job safety analysis or equivalent planning document” as the same thing done under different headings, and Site Safe titles one of its own SSSP forms “Task Analysis (TA) and Safe Work Method Statement (SWMS)”. So if the paperwork you have been sent asks for a TA, a SWMS or a JSA, this is the document it means, written to the Health and Safety at Work Act 2015. Only the name changes; the hazards, controls and ratings are the same either way.
Where this sits in your SSSP
A Site-Specific Safety Plan (SSSP) covers the whole job: who is on site, how hazards get reported, what happens in an emergency. A Task Analysis covers one task inside it. They are not the same document. Site Safe’s SSSP pack runs to ten forms, and the Task Analysis is Form 10, filed behind the plan itself.
So a main contractor who asks which SSSP pack you are using, and then asks for a TA covering wet area waterproofing, has asked you for two separate things. This is the second one. Keep it with your SSSP for the job and bring it to the pre-start briefing, because the value is in the crew having read it before the work starts.
