Equipment design review checklist

An equipment design review is a set of gate reviews that a new machine passes through before it is ordered, before it is built and before it starts up. The idea is simple: most problems with a new machine are designed in, and a problem found on paper before the order costs far less to fix than one found on the line. This checklist has 32 checks, phrased so that Yes is good: eight at each gate and eight for a safety buy-off before first use. It starts from the weak points of the machines you run today, turns them into requirements, and checks access, lubrication, guarding, spares, training and the maintenance plan. A problems journal records each problem, the gate where it was found and the gate where it should have been found. The PDF has the gate forms, the journal and a worked example; the Excel version counts the answers and the problems for you.

When to use it

When to use an equipment design review

  • When buying or building a new machine, line or major modification, from the first specification to start-up.
  • When your current machines have repeat problems with access, cleaning, lubrication or breakdowns that you do not want to buy again.
  • To bring operators and maintenance into the design, so their experience is in the specification and not found at start-up.
  • To give the project a clear stop or go at three points, with evidence behind each decision.
  • Not for routine inspection of a machine in service. For that, use an inspection or PM checklist; this is for equipment that does not yet exist or is not yet running.

How to fill it in

  1. 1

    Start from today's weak points

    List what goes wrong on the machines you run now: breakdowns, stops, long cleaning, defects, injuries. Turn each into a requirement in the specification, with a number where you can.

  2. 2

    Review at gate 1, before the order

    Check the eight specification items with operators, maintenance, safety and engineering. Reliability, maintainability, cleaning, safety, changeover and energy targets must be written down before the order is placed.

  3. 3

    Review at gate 2, before the build

    At the design freeze, walk through the drawings: can every routine point be reached safely, are lubrication points grouped, do guards stay on, are the spares and the fault messages agreed.

  4. 4

    Review at gate 3, before start-up

    Check the installed machine: the acceptance test, the PM plan, the spares on site, the manuals, the training and the written routines for cleaning, inspection and lubrication.

  5. 5

    Do the safety buy-off

    Before the machine runs product, check the risk assessment, the guards and stops, the isolation points, the training and the conditions for first use. It is a general starting point to adapt to local law.

  6. 6

    Keep the journal and learn from it

    Log every problem with the gate where it was found and where it should have been found. After the first month, add a check for each problem that was found later than it should have been.

What each gate checks

The 32 checks over three gates and a safety buy-off

Eight checks at each of the three gates (before order, before build and before start-up) and eight for the safety buy-off. A check is phrased so that Yes is good. On the sheets each one is answered Yes, No or N/A with a line of evidence; a No holds the gate until it is fixed or accepted.

Gate 1: before order

Requirements written from the weak points of the machines you run today

  1. 1The weak points of today's machines (breakdowns, stops, cleaning time, defects, injuries) are listed, and each one has a requirement in the specification
  2. 2Reliability targets are in the specification: MTBF and MTTR, with the supplier's evidence from machines in similar use
  3. 3Maintainability requirements are written: access, tools needed, time to change wear parts, standard components
  4. 4Cleaning and inspection requirements are written, including how long routine cleaning and inspection may take
  5. 5Safety requirements name the standards and the risks to be designed out first, before guarding is added
  6. 6Changeover and setup time targets are written, with the number of tools needed
  7. 7Energy, compressed air and consumable use limits are written, and a ten-year cost comparison has been done on the options
  8. 8Operators, maintenance and safety have reviewed the specification and their comments are recorded

Gate 2: before build

The design freeze: last chance to change it cheaply

  1. 9Every point that needs routine access (lubrication, inspection, adjustment, cleaning) can be reached safely without removing guards or other parts
  2. 10Lubrication points are grouped, labelled and reachable from outside, and the lubricant is stated for each
  3. 11Guards and interlocks follow the risk assessment, and no guard has to come off for normal operation or routine work
  4. 12Sensors and test points are fitted where condition monitoring or fault finding needs them
  5. 13Wear parts and consumables are standard, from more than one source where possible, and listed
  6. 14A recommended spares list with lead times and prices is agreed, and the critical spares are ordered with the machine
  7. 15Controls, alarms and fault messages are clear to an operator, and the first-response actions are written
  8. 16Problems found at earlier reviews are closed, or have an owner, a date and an agreed decision

Gate 3: before start-up

Ready to run, and ready to be looked after

  1. 17The machine has run the agreed acceptance test (speed, quality, run time) and the results are recorded
  2. 18The PM plan (tasks, intervals, owners) and the operator care checks are written and loaded into the maintenance system
  3. 19The spares agreed at gate 2 are on site, in the store, with part numbers
  4. 20Manuals, drawings, electrical diagrams and software backups are delivered and filed
  5. 21Operators, maintenance and the line leader are trained and have signed off, and standard work for operation is written
  6. 22Standard cleaning, inspection and lubrication routines are written and have been tried once on the machine
  7. 23The list of open points left after start-up has an owner and a date for each
  8. 24A review after the first month is booked, to compare the early failures with the requirements

Safety buy-off before first use

A general starting point: adapt it to local law and your own procedures. Not legal advice

  1. 25A risk assessment of the installed machine has been done and every high risk is controlled
  2. 26Guards, interlocks, emergency stops and light curtains were tested and work, and the tests are recorded
  3. 27Energy isolation points are identified and labelled, and a lockout procedure for the machine is written
  4. 28Noise, dust, fumes and other exposures were checked against the limits that apply
  5. 29The people who will operate or maintain it were trained on its hazards and the safe working procedure
  6. 30Warning labels, floor markings and safety signs are in place
  7. 31A safety person has signed that the machine may be used, and any conditions are written on the sign-off
  8. 32The conditions for first use, such as trial runs, limited speed or supervision, are written down

A filled-in example

Illustrative, not a benchmark

An invented new labeller goes through all three gates, and 31 problems are logged over the project.

  • 19 are found at gate 1, before the order: a missing cleaning time limit, no MTBF evidence and a label head blocked by the frame among them. Each is a line in the specification.
  • 6 more are found at the design freeze and fixed before the build, such as a lubrication point behind a panel and a guard that needs a tool to open.
  • 3 are found at gate 3 and 3 at start-up, and all 6 should have been caught at gate 2: a drain that cannot be reached, a missing fault list, spares not delivered and a product guide that needs tools.
  • 29 of the 31 problems are closed. The spares are still open, and gate 3 is held until they arrive.

Over three in five problems were found before the order, but six escaped the design freeze. The journal turns them into new checks, so the next machine's gate 2 catches them.

Common mistakes

  • Reviewing only at the end

    A single review at start-up finds problems when they are most expensive. The gates exist to find them while a change is a line in a drawing.

  • Leaving out the people who will run it

    Engineers can check a design against a standard, but operators know where they cannot reach and technicians where they cannot get a spanner. Have both at gate 2.

  • Writing requirements nobody can check

    Easy to maintain is not a requirement. Time to change the wear part, access without removing guards and a target MTBF are. Give each requirement a number or a test.

  • Passing a gate with open Nos

    A No can be accepted, but only with an owner, a date and an entry in the journal. A gate passed on goodwill is where late problems come from.

  • Treating the safety buy-off as a signature

    The buy-off is a check of guards, stops, isolation and training that were tested, not a form signed because the machine is late. Adapt it to local law and your own procedures.

FAQ

Equipment design review checklist: common questions

  1. An equipment design review is a gate review of a new machine before it is ordered, before it is built and before it starts up. Each gate checks that requirements, design and readiness are right while a change is still cheap, and the problems found are recorded.

  2. A common set is before order (is the specification right), before build or design freeze (is the design maintainable and safe) and before start-up (is the installed machine ready to run and be looked after). Some plants add a review after the first month of running.

  3. When every check is phrased the same way, a quick scan down the Yes column shows the state of the review, and a No stands out. Mixed wording, where Yes is sometimes bad, leads to wrong answers.

  4. This template's safety buy-off is a general starting point, not legal advice. The legal requirements for machinery depend on where you are, and your own safety procedures and the machine's risk assessment govern. Adapt it to them.

  5. It records each problem, the gate where it was found and the gate where it should have been found. Problems found later than they should have been show where the reviews are weak, and each one becomes a new check for the next machine.
