Start with the process
Describe what will happen inside the cupboard, including substances, concentrations, heat sources, equipment and normal operating duration. Attach relevant safety data sheets and identify who is responsible for the workplace risk assessment.
Use the local exhaust ventilation guide to see how capture, transport, air movement and discharge fit together. The brief should describe the intended task clearly enough for the team to assess those parts.
Create a responsibility schedule
| Interface | Agree who provides it |
|---|---|
| Process requirements | Hazards, apparatus and operating scenarios. |
| Cupboard selection | Model, size, connections and operating duty. |
| Building services | Room ventilation, electrical supplies and service connections. |
| Exhaust route | Ducting, fan, supports, penetrations and discharge assessment. |
| Handover | Testing, records, instructions and training. |
Record assumptions before quotation
Distinguish measured site dimensions from provisional layout information. Identify access limits, roof work, occupied areas and activities that may restrict installation. Include any planned future expansion as a separate requirement for review.
Our installation planning guide covers site preparation. The cost guide helps you compare scopes without overlooking associated building work.
Use a review point before ordering
- Confirm the process and selected cupboard together.
- Review the final duct route and fan duty.
- Coordinate replacement air and controls with the mechanical designer.
- Agree access, services and installation responsibilities.
- Define acceptance checks and the records required at handover.
Record changes to the brief as the design develops. A late change to apparatus, chemicals or the route should return to the relevant designer for assessment, with the equipment schedule updated to match.
