Mobile Concrete Crusher Task Analysis
Operation of a mobile crushing plant to crush demolition concrete and rubble, including feeding, blockage clearing, magnet and conveyor operation and stockpiling.
What you get
One editable Word document covering mobile concrete crusher for Demolition & Strip-out: 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 |
| Site and set up the crusher | Unstable set-up or uncontrolled traffic interaction |
| Complete the pre-start inspection | Failure of guards, e-stops or wear components |
| Feed the crusher | Excavator striking the hopper; oversize material ejecting from the chamber |
| Crushing chamber and ejected material | Struck by violently ejected rock or steel from the chamber |
| Clear blockages | Drawn into the chamber or struck by released material - fatal |
| Operate conveyors and magnet | Entanglement in belts or rollers; struck by discharged steel |
| Control contaminants in the feed | Asbestos or hazardous waste crushed with the concrete |
| Control dust including crystalline silica | Respiratory disease from crushing dust |
| Control noise | Hearing damage around the operating crusher |
| Manage stockpiles and product handling | Engulfment or collapse of stockpiles; loader interaction |
| Track and shut down the plant | Crush during tracking; unauthorised access |
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.
About Demolition & Strip-out Task Analysis
This is one of the Task Analysis documents written for Demolition & Strip-out crews. The trade covers soft strip and structural demolition, asbestos and lead, services isolation, exclusion zones, loadout.
See every Demolition & Strip-out document, or the whole pack for $199.99. Need 5 or more templates from this trade? The pack costs less than buying them individually, and saves $49.96 at 5.
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 mobile concrete crusher, 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.
