Risk Assessment Description:

This free Biogas and Anaerobic Digestion Plant Fire Safety fire risk assessment template is designed for plant operators, engineers and safety managers who need a quick, compliant way to assess fire and explosion hazards in biogas facilities. Whether you’re designing a new anaerobic digestion plant, commissioning a biogas generator, or reviewing existing safety procedures, this biogas fire risk assessment example provides pre‑filled hazards and control measures you can customise.

The template covers all key fire and explosion risks for biogas plants, including methane leaks, static discharge, hot‑work activities, overloaded electrical equipment, pressure vessel failure, feedstock storage, and inadequate emergency shutdown. It also addresses related hazards such as confined‑space entry, waste handling, and inadequate fire‑fighting access.

Use this template for:

  • Plant risk planning – quickly identify fire and explosion hazards before work starts.
  • Safety briefings – provide clear, actionable control measures to staff and contractors.
  • Regulatory compliance – demonstrate adherence to COMAH Regulations 2015, Regulatory Reform (Fire Safety) Order 2005, Control of Substances Hazardous to Health Regulations 2002 (COSHH) and HSE Publication SR2021 No 6 – Anaerobic Digestion Facility – Installations.

Each hazard includes suggested control measures covering leak detection, gas monitoring, grounding, equipment maintenance, safe hot‑work permits, emergency shutdown procedures, and fire‑fighting provisions. 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: COMAH Regulations 2015, Regulatory Reform (Fire Safety) Order 2005, Control of Substances Hazardous to Health Regulations 2002 (COSHH) and HSE Publication SR2021 No 6 – Anaerobic Digestion Facility – Installations.

Yes — completely free. Over 1300 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?

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 1300 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 1300 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 up to 3 risks, Free accounts up to 5 risks, Standard up to 15 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.
