A finished Word report (.docx) with every hazard, your answers, the residual risk and your Action Plan already in it – to print, sign and keep with your safety records.

The pre-written Inherent Risk Assessment (.docx): every hazard in this section with what could go wrong, the possible consequence and its inherent risk rating – your reference copy, to read before the walk and share with the people you consult.

A printable Word walkthrough checklist for marking by hand on the workshop floor, an illustrated Quick Start Guide (PDF) and a one-page calculator login sheet.

Section E – Liner and Membrane Fabrication

What this pack is

Liner fabrication looks low-risk next to the steel side of the workshop, and that is why it is usually left out of the risk assessment. It should not be: heated plastics give off irritant and toxic fume, solvent cements are highly flammable, liner material burns fiercely once alight, and rolls and folded liners are some of the heaviest and most awkward manual handling in the building.

This section covers unrolling, measuring and cutting membrane; hot-air and hot-wedge seam welding; extrusion welding of PP and PE fittings and boots; solvent bonding and adhesive patching of PVC liners; seam testing by air lance, vacuum box and spark test; and folding, packing and palletising.

It suits any business welding geomembrane, pond and tank liners or thermoplastic sheet.

The risk

The most serious hazards in liner and membrane fabrication

A sample of the 27 hazards in this section, each shown with its consequence and the inherent risk rating given by a Certified Industrial Hygienist before any controls are counted. The controls themselves are in the calculator.

Electric shock from welders and leadsHigh

Electric shock, fatality. General Safety · inherent risk 4B.

Fire involving plastic liner materialHigh

Rapid fire with toxic smoke (hydrogen chloride from PVC); major property damage. Fire and Explosion · inherent risk 4B.

Flammable vapour ignitionHigh

Flash fire or explosion; serious burns; major property damage. Fire and Explosion · inherent risk 4B.

Fume from heated plasticMed

Eye and respiratory irritation; headache. Occupational Hygiene · inherent risk 3C.

Solvent vapour (THF, cyclohexanone, MEK)Med

Headache, dizziness, narcosis; liver effects with long-term exposure; eye irritation. Occupational Hygiene · inherent risk 3C.

Handling heavy liner rollsMed

Crush injuries to feet and legs; back injury. General Safety · inherent risk 3C.

Burns from hot extrudateMed

Burns. General Safety · inherent risk 3C.

Compressed air lanceMed

Eye injury; air injection into skin. General Safety · inherent risk 3C.

Manual handling (ergonomics)Med

Low back, shoulder and hand injuries (musculoskeletal disorders – the most common serious workers' compensation claim type in Australia). Occupational Hygiene · inherent risk 2D.

A worked example

How one hazard is rated

Hazard E2.2 – Electric shock from welders and leads – starts with an inherent risk of 4B, rated before any controls are counted. The calculator lists 3 controls for it, from elimination and engineering down to PPE, monitoring and emergency arrangements. You answer Yes, No or N/A for each on the floor. Once the last one is answered, the calculator works out the control score, applies any severity reduction earned by physical controls, and shows the residual risk as RED, YELLOW or GREEN. Every control you answered No to goes into your Action Plan, most urgent and most effective first, ready for a responsible person and a due date.

What's built in

How your controls are scored

Not generic advice — the specific, hierarchy-of-controls measures written into the pack, matched to how these assets actually fail.

01Every control is classified on the hierarchy of control – elimination, substitution, engineering, administrative, PPE, monitoring and emergency – and physical controls earn more credit than rules and PPE.
02Controls that limit how severe an injury could be are marked, and only those can lower the severity rating of a hazard.
03Controls answered N/A are left out of the score, so the result reflects the protection that applies at your site.
04Natural ventilation earns no credit for diesel exhaust, container gases or other carcinogens – acceptability rests on source control and measurement.
05Every control answered No becomes an action, ranked red before yellow before green and most effective first, with a responsible person and a due date.
06Emergency and monitoring controls still appear in the Action Plan when missing, even though they do not change the score.

This is a generic risk assessment for a typical workshop, to support your due diligence – completing it is not compliance in itself. You must answer it for your own site, consult your workers, put the missing controls in place, and get competent advice where it says so – for example exposure monitoring by an occupational hygienist. The limits of the assessment are set out in “How it works” and at the front of every report.
