“The generator saved us hours on our AHU replacement programme. The RAMS covered F‑Gas, hot works and commissioning in one place and passed principal contractor review first time.”
5 star ratingLiam O’Connor· Contracts Manager, M&E Contractor
What you get
- HVAC RAMS covering ductwork, refrigeration, controls and commissioning phases with embedded permit prompts.
- Lift and access matrix linking plant weights, lifting method and operator competencies for quick review.
- F-Gas and pressure-test record template capturing nitrogen purge, evacuation and leak results.
- Hot works and fire-stopping checklist tuned to brazing and penetration sealing tasks.
Benefits
- ✓Reassure PCs that WAH, hot works and F-Gas duties are fully planned before you mobilise.
- ✓Reuse the same structure for AHU swaps, VRF installs or duct upgrades with minimal edits.
- ✓Give commissioning engineers the data fields they need for O&M packs without chasing separate logs.
Risks of manual RAMS
- !Incomplete lift or MEWP planning is a key reason HVAC RAMS get rejected on major projects.
- !If pressure test and F-Gas evidence isn’t captured, handover is delayed and warranty support suffers.
- !Generic RAMS often ignore fire-stopping reinstatement leading to fire strategy non-compliance.

Typical manual prep vs RAMSGen automation
An HVAC and ventilation risk assessment and method statement for ductwork, AHUs, condensers and refrigerant pipework. Pre-filled hazards cover brazing hot works, F-Gas refrigerants (R32, R410A), pressure testing, manual handling of plant, and crane lifts of roof units. Controls align with F-Gas Regulations, PSSR, LOLER and CDM 2015 — adapt to your equipment specs before exporting.
HVAC & Ventilation RAMS — Key Requirements & Controls
CDM 2015 compliance notice
Under CDM 2015, generic templates are not compliant and cannot be used directly on site. The HSE requires every RAMS to be tailored to your specific project conditions, site layout, and identified hazards. Using an unmodified template without site-specific adjustments exposes you to enforcement notices, project delays, and potential prosecution.
The content below provides a baseline understanding of typical hazards and controls for HVAC & Ventilation work. It is not suitable for use on site until you have tailored it to reflect your actual working conditions, project location, and team.
RAMSGen generates a compliant, site-specific HVAC & Ventilation RAMS for you in minutes.
Snapshot hazards
- Working at height when installing ductwork, fans and AHUs (ladders, towers, MEWPs).
- Manual handling and lifting of heavy or awkward plant, duct sections and coils.
- Hot works during brazing/soldering with fire, fume and oxygen‑depletion risks.
- Electrical hazards from temporary power, tools, and energisation during testing/commissioning.
- Refrigerant and pressure hazards (asphyxiation, frostbite, A2L flammability) and stored energy in pipework/receivers.
Critical controls
- Work at Height plan: engineered access (towers/MEWPs), IPAF/PASMA operators, edge protection, exclusion zones and rescue arrangements per WAHR.
- Manual handling and lifting: task assessment, mechanical aids (trolleys/hoists), team lifts, load limits, and LOLER/PUWER‑inspected lifting gear.
- Hot works control: permit to work, fire watch and extinguishers, heat‑resistant shields, LEV for fume, cylinders secured and segregated; post‑work fire check.
- Isolation and service detection: up‑to‑date drawings/as‑built, cable/pipe scanning, permit to penetrate, lock‑out/tag‑out of electrical/gas/plant; 110V tools and RCDs.
- Refrigerant/pressure safety: F‑Gas‑certified handlers, ventilation and leak detection, nitrogen purging during brazing, calibrated gauges for strength/tightness tests, compliance with PSSR and manufacturer limits.
Permits & references
- General Permit to Work (site rules).
- Hot Works Permit for brazing/soldering/welding.
- Electrical Isolation/LOTO certificate for plant and circuits.
- Working at Height/MEWP permit where required by site.
- Permit to Penetrate and asbestos clearance/verification for any openings.
Implementation walkthrough
- 1
Pre‑start briefing and review of RAMS, drawings and permits (hot works, WAH, isolate/LOTO). Confirm asbestos survey and permit to penetrate for any openings.
- 2
Set up access: barriers, signage and exclusion zones. Erect tower scaffold or position MEWP by trained operators; inspect and tag access equipment.
- 3
Deliver, store and handle materials/plant using mechanical aids. Conduct lift(s) with LOLER-inspected equipment; inspect slings/LOLER tags and establish clear communications.
- 4
Install supports/hangers to specification; verify fixings and fire‑stopping details. Keep work area tidy; remove sharp swarf and protect edges.
- 5
Install ductwork/fans/AHUs: align, bolt and seal joints; fit anti‑vibration mounts. Maintain safe posture and team lift long sections.
- 6
Install copper refrigeration/condensate lines: purge with nitrogen, braze under hot works permit, cool and protect combustibles; label pipework.
- 7
Pressure testing and evacuation: perform strength and tightness tests with calibrated gauges; evacuate to required microns; record results.
- 8
Electrical/controls: verify isolation, terminate to manufacturer specs and BS 7671, label circuits, test and inspect before energisation.
- 9
Insulation, fire stopping and final fix: apply insulation and vapour barriers; reinstate rated fire seals around penetrations; complete snag rectification.
- 10
Commissioning and balancing: set airflow/pressures, verify rotation and controls, run‑test and record data; clear site, remove waste and handover O&M documentation.
How to create a site-specific HVAC & Ventilation RAMS
Transform the generic template above into a compliant, site-specific document by addressing these critical areas:
Site-specific customization checklist
- 1
Project location, floor levels and plant room access/egress routes.
- 2
Working hours, noise limits and any out‑of‑hours requirements.
- 3
Interface with other trades and building users; isolation coordination.
- 4
Location of emergency shut‑offs (electric, gas, sprinkler) and first‑aid points.
- 5
Delivery routes, lay‑down areas and crane/MEWP positioning constraints.
- 6
Fire strategy: alarm zones, detector isolations and fire‑stopping details.
- 7
Environmental controls: dust, fume, refrigerant storage and spill response.
- 8
Specific equipment models, weights and lifting points for AHUs/fans/condensers.
- 9
Commissioning requirements and witnessing plan (airflow, pressure, BMS).
- 10
Client documentation: O&M, test certificates, F‑Gas log and asset labels.
HSE compliance alert
This RAMS outline is a template to support compliance with UK law (HSWA, MHSWR, WAHR, EAWR, PSSR, COSHH, F‑Gas). You must adapt it to the specific site, equipment and sequence of work, obtain all required permits, and ensure competent supervision and verification before starting.
Why RAMSGen makes this easier
Instead of manually editing Word templates and cross-referencing multiple guidance documents, RAMSGen walks you through each customization step with intelligent prompts. Answer questions about your site, and the platform automatically generates a compliant RAMS that incorporates:
- Project-specific hazards based on your site layout and access constraints
- Emergency plans with routes to the nearest A&E and site-specific assembly points
- Permits, inspections, and quality checkpoints aligned to your schedule
- Branded PDF exports ready for principal contractor submission
