Risk Assessment Description:

This free reactor vessels risk assessment template is designed for manufacturing operatives, process engineers and maintenance staff in chemical production facilities. Whether you’re setting up a batch reaction in a pressurised reactor, performing routine cleaning and de‑contamination, or conducting maintenance on agitators and heating systems, this reactor vessels risk assessment example provides pre‑filled hazards and control measures you can customise.

The template covers all key risks for reactor vessels and batch processing, including over‑pressure release, exothermic runaway, toxic gas exposure, hot surface burns, moving‑part entanglement, manual handling of heavy components, electrical isolation failures, noise, vibration and cleaning‑related slips. It also includes specific controls for hazardous substances in line with COSHH, equipment guarding per PUWER and major‑accident prevention under COMAH.

Use this template for:

  • Pre‑job risk planning – quickly identify reactor‑specific hazards before a batch run.
  • Operator briefings – provide clear, actionable control measures to the crew.
  • Compliance documentation – demonstrate adherence to PUWER 1998, COSHH 2002 and COMAH 2015.

Each hazard includes suggested control measures covering process monitoring, interlocks, personal protective equipment, ventilation, isolation procedures and more. The risk matrix uses a standard 5×5 likelihood‑severity scoring, with controlled severity always matching the initial severity as required by HSE guidance.

Fully editable and shareable – customise hazards, add site‑specific risks, adjust control measures to match your conditions, then download as a PDF for records or share with your team.

Compliant with: Provision and Use of Work Equipment Regulations 1998 (PUWER)【PUWER page】, Control of Substances Hazardous to Health Regulations 2002 (COSHH)【COSHH page】, Control of Major Accident Hazards Regulations 2015 (COMAH)【COMAH guidance】, Pressure Systems Safety Regulations 2000 (PSSR) for relief valve design, and HSG143 guidance on safe chemical reaction processes.

Frequently asked questions

Are these risk assessment templates really free to download?

Yes — completely free. Over 1500 free UK risk assessment templates, free to use forever, no signup required for guests, no paywall. Customise to your workplace and download as a professional HSE-compliant PDF in minutes.

Can I download risk assessment templates in PDF or Word format?

Risk assessments download as a professional, HSE-compliant PDF — ready to print and file as-is. Word (.docx) export is not available for risk assessments, but you can fully customise every hazard, control measure, persons-at-risk entry and rating online before you download.

Are the risk assessment templates HSE-compliant?

Yes. Every template aligns with HSE guidance and the HSE 5-Step Risk Assessment process. They cover the requirements of the Management of Health and Safety at Work Regulations 1999, COSHH 2002, Manual Handling Operations Regulations 1992, Work at Height Regulations 2005, and other relevant UK regulations.

What industries do the risk assessment templates cover?

Over 1500 templates across every UK industry — painting, electrical, HVAC, plumbing, carpentry, concrete, solar panel installation, asbestos, scaffolding, working at height, manual handling, fall protection, hot works, confined space entry, lifting operations, kitchen fitting, plumbing, drywall, tiling, plastering, and many more.

What's the difference between a risk assessment form and a risk assessment template?

A risk assessment form is the blank document; a risk assessment template is a pre-filled form ready to customise. Our generator gives you both — a free interactive form you fill in plus over 1500 pre-written templates you can customise to your specific workplace.

Do I need to create an account to use the risk assessment templates?

No — guests can generate and download risk assessments for free without signing up. Register a free account if you want to save documents to your dashboard, edit them later, or share them for digital signatures.

Can I customise the risk assessment templates to my workplace?

Yes — fully. Edit hazards, control measures, persons at risk, likelihood and severity ratings, PPE requirements, and review schedules. Each template is a starting point you tailor to your specific operation.

How many risks can I add to a single risk assessment?

The number of risks (hazards) you can include in one assessment depends on your plan: guests get unlimited risks, Free accounts unlimited risks, Standard unlimited risks, Pro unlimited risks, and Enterprise unlimited risks per assessment. You can add and preview every risk in a template, then tick the ones to include up to your plan limit — upgrade any time for more. See our pricing page for the full plan comparison.

Are these risk assessment templates valid for UK construction work?

Yes. Our construction-specific risk assessment templates align with HSE construction guidance, the Construction (Design and Management) Regulations 2015 (CDM 2015), and the Work at Height Regulations 2005. Templates cover scaffolding, working at height, concrete pouring, excavation, roofing, electrical installation, and more.

How often should I update my risk assessment?

Whenever there is reason to believe the assessment is no longer valid — after workplace changes, near-misses, accidents, new equipment, new substances, or new processes. HSE guidance recommends an annual formal review at minimum.

What is the HSE 5-step risk assessment process?

Step 1: Identify the hazards. Step 2: Decide who might be harmed and how. Step 3: Evaluate the risks and decide on precautions. Step 4: Record findings and implement them. Step 5: Review the assessment and update if necessary. Our interactive generator walks you through all 5 steps.

Can I use these risk assessment templates for self-employed work?

Yes. Self-employed workers are required to assess risks to themselves and anyone affected by their work. Our templates are suitable for sole traders, contractors, and small businesses.

Do you have RIDDOR-aligned risk assessment templates?

Yes. Several templates cover RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013) requirements — including accident reporting and investigation risk assessments. All RA templates support incident logging and review.
