The guard that gets removed: designing for changeover
A guard that makes a changeover twice as slow will come off eventually. How to design guarding and interlocks around how the machine is really operated, not how the manual describes it.
Manufacturing
Practical Safety. Real Controls. Better Work.
Production does not stop for a clipboard. We walk the floor with you across a real shift, from goods-in to dispatch, to understand the plant, the traffic, the substances, and the people before we recommend a single control.
Machine guarding and interlocks, isolation and lockout, forklift and pedestrian separation, hazardous substances, noise, and dust. We target what actually injures people on a factory floor and design controls that survive the schedule.
Nights, weekends, contractors, and new starters on a busy week. We build inductions, permits, and supervisor routines that keep standards steady when the pressure is on and the experienced operator is on leave.
Manufacturing
ProperSafe works with New Zealand manufacturers, processors, and workshops. Manufacturing injuries are rarely mysterious, they come from unguarded plant, isolation that was skipped, forklifts sharing space with people, and exposures that build quietly over years. What makes them hard is that the fix has to work without stopping the line.
We are not a paperwork business. We get on the floor, watch how the work is really done across a shift, and build controls your operators will use at 3am on a Sunday, not just on the day of the audit.
What We Do
From plant and guarding through to hazardous substances, traffic management, and health monitoring, practical support with no filler.
01
A right-sized H&S system for your operation. Hazard registers, permits, and records that satisfy WorkSafe and actually get used on the floor, not filed and forgotten.
02
Guarding assessments, interlocks, and safe isolation and lockout procedures for presses, conveyors, mixers, and rotating plant. The highest-order controls, applied where they count.
03
Compliant storage, handling, and labelling under the HSNO rules. Inventories, SDS management, ventilation and extraction review, and exposure monitoring against workplace exposure standards.
04
Separating people from moving plant. Site traffic plans, pedestrian routes and barriers, loading dock controls, and operator competency for forklifts and reach trucks.
05
The exposures that injure slowly. Noise surveys, vibration assessment, and health monitoring programmes that catch harm early rather than at the exit medical.
06
Root cause analysis, corrective actions, and WorkSafe notification support when something goes wrong, so your operation learns from events rather than just recording them.
Our Approach
Too many manufacturing safety programmes default to the bottom of the hierarchy. Earmuffs get issued, a procedure gets written, and the guard stays off because it slows the changeover. That is not safety. It is the appearance of safety.
ProperSafe focuses on the top three. We start by honestly mapping where your current controls sit, then work upward. Can the task be designed out? Can a safer substance or process be substituted? Can the plant be engineered so the operator cannot reach the danger zone at all?
Where administrative controls are genuinely the right answer, they still have to work. That is where NeuroSafe and our Safety Tech & AI practice come in: documents people actually read, and systems that keep a control alive instead of leaving it in a folder. See Safety Tech & AI →
The result is a floor where your people are protected by design, not by hoping everyone stays sharp at the end of a twelve-hour shift. That is what practical safety looks like.

Separation beats awareness every time. Practical traffic management for busy sites, from marked routes and barriers through to loading dock controls and reversing.
Noise, dust, solvents, and vibration rarely cause an incident report. A look at monitoring and health surveillance that catches slow harm while it is still reversible.
