RAMS vs COSHH Assessment — What's the Difference?

By the Riskora Editorial Team · Reviewed against our editorial standards · Last reviewed

RAMS and COSHH assessments both deal with workplace safety, but they cover different things and exist under different regulations. Here's a clear explanation of what each document does, when you need them, and how they relate to each other.

What is the difference between RAMS and COSHH?

RAMS (Risk Assessment Method Statement) covers general workplace hazards and describes safe work procedures for a specific task or project. COSHH (Control of Substances Hazardous to Health) assessments specifically cover risks from hazardous substances — chemicals, dust, fumes, and biological agents. You may need both: RAMS for the overall work, plus a COSHH assessment if hazardous substances are involved.

Confusing RAMS and COSHH Creates Compliance Gaps

Some contractors include substance hazards in their RAMS and assume that's sufficient. It isn't. COSHH assessments have specific requirements under the COSHH Regulations 2002 — including exposure limits, health surveillance triggers, and specific control hierarchies — that a general risk assessment doesn't cover. Understanding the complete guide to RAMS in the UK helps frame why proper documentation matters.

How Riskora Helps

Riskora generates RAMS with integrated hazard identification that flags when COSHH-relevant substances are present in your work type. While Riskora focuses on the RAMS document itself, the hazard library includes substance exposure risks and appropriate control measures. You can also use our standalone risk assessment builder or method statement tool.

Who it's for

  • Construction work involving dust (cutting, grinding)
  • Painting and decorating
  • Adhesive and sealant application
  • Demolition with potential asbestos
  • Welding and hot works
  • Cleaning with chemical products

Do I need COSHH as well as RAMS?

Yes, if your work involves exposure to hazardous substances. RAMS cover general work hazards (falls, struck-by, manual handling). COSHH specifically assesses substance exposure risks — silica dust, solvents, adhesives, cement, paints. The two documents are complementary, not interchangeable.

What substances need a COSHH assessment?

Any substance that could harm health through inhalation, skin contact, ingestion, or injection — including construction dust (silica, wood, MDF), cement, paints and solvents, adhesives, cleaning chemicals, welding fumes, and asbestos. If a substance has a hazard warning on its packaging, it likely needs a COSHH assessment.

Key Risks and Considerations

  • Treating RAMS as a substitute for COSHH assessments
  • Missing substance hazards in general risk assessments
  • Not identifying COSHH-relevant materials before work starts
  • Failing to implement substance-specific controls

Key Features

  • RAMS generation with substance hazard flags
  • Pre-loaded controls for dust and chemical exposure
  • PPE requirements for substance work
  • Professional document formatting
  • Under 5 minutes to generate
  • Integrated hazard identification

Inside the document

What your RAMS actually contains

Riskora builds a structured, client-facing document — not a generic AI paragraph. Every section is shaped around your job, your site and your team.

  • Hazards

    Task-specific hazards for the job, captured row by row — not a generic list pulled from an old RAMS.

  • Controls

    Control measures mapped to each hazard with residual risk scoring after controls are applied.

  • PPE

    PPE requirements tied to the activity and site, ready to brief to the team.

  • Method steps

    Step-by-step method statement structured around how the work is actually sequenced on site.

  • Emergency arrangements

    First aid, rescue plan, emergency contacts and site-specific escalation routes.

  • COSHH prompts

    Substance prompts when the work involves chemicals, dusts, fumes or sealants — flagged early, not missed at review.

  • Sign-off

    Operative sign-off captured against the document — names, dates and acknowledgement of the brief.

  • Version history

    Every change tracked so you can show what was issued, when, and which version the team signed.

  • Approval status

    Clear approval state on every document — draft, in review, approved, issued — visible across the team.

  • Audit trail

    Who created it, who reviewed it, who signed it. A complete trail you can hand to a principal contractor or auditor.

Before & after

From copied-and-pasted to site-specific

The reason RAMS get rejected is rarely the format — it's that the document is obviously generic. Riskora rebuilds it around this job, this site and this task.

Before

Generic template copied from an old job.

  • • Hazards and controls that don't match this site or task.
  • • Method steps written for a different sequence of work.
  • • No emergency arrangements specific to the location.
  • • Client flags it as generic and asks for a rewrite.
After

Site-specific document structured around this job, site and task.

  • • Hazards captured from the actual scope you pasted in.
  • • Method steps sequenced for how the work runs on site.
  • • Emergency arrangements and rescue plan tied to the location.
  • • Approved internally, briefed to the team, signed off and stored.
How it works

From job details to signed-off document

A four-step workflow used by contractors, consultants and safety teams to turn informal job details into client-ready safety paperwork.

  1. 1
    Paste job details

    Drop in a client email, a WhatsApp from the site manager, a scope of works or a tender note. Anything that describes the job.

  2. 2
    Riskora structures the document

    Riskora turns your brief into hazards, controls, method steps, PPE, emergency arrangements and COSHH prompts.

  3. 3
    Review, edit and download

    You stay in control of every section. Tweak anything, then download a clean PDF or share a link.

  4. 4
    Brief the team and record sign-off

    Brief operatives, capture their sign-off and keep a full audit trail of who signed which version.

Frequently Asked Questions

You can reference substance hazards in your RAMS, but a separate COSHH assessment may be needed for detailed substance-specific evaluation — especially where workplace exposure limits and health surveillance are relevant.

Safety data sheets (SDS) from substance manufacturers provide the information needed for COSHH assessments. The HSE also publishes guidance on COSHH requirements for construction.

RAMS as a single document is not named in UK law, but the underlying duties are. The Management of Health and Safety at Work Regulations 1999 require a suitable and sufficient risk assessment, and CDM 2015 effectively requires a written method statement on most construction work. A RAMS satisfies both in one document, which is why principal contractors expect to see one.

Anyone competent to assess the risks of the work. Most subcontractors write their own RAMS for the tasks they carry out — formal qualifications aren't required, but the writer needs to genuinely understand the hazards, the controls and the site. Principal contractors will reject documents that look like they were written by someone who hasn't done the job.

Long enough to cover every hazard and method step honestly — usually 4 to 12 pages. Short, vague RAMS get rejected. Padded ones get skim-read on site, which defeats the point. Aim for specific, not lengthy.

At minimum: before each new site, after any significant change to the work, and after any near-miss or incident. Many principal contractors also expect a documented annual review even if nothing has changed.
