Lone Workers Face Increased Risk

Lone working on construction sites means there's no one immediately available to help if something goes wrong — a fall, a medical emergency, or an equipment failure. The Management of Health and Safety at Work Regulations 1999 require employers to assess the risks of lone working and put controls in place. The risk assessment must address communication, emergency response times, and the types of work that should never be done alone. Many professionals are unsure about the legal requirements for safety documentation.

The HSE states that employers must assess whether the work can be done safely by one person and put arrangements in place to keep lone workers safe. This includes communication, supervision, and emergency procedures.

How Riskora Helps

Riskora generates lone working risk assessments with structured controls covering communication systems, buddy check-in schedules, prohibited solo activities, welfare arrangements, and emergency response procedures. Try the RAMS generator to see how quickly you can produce professional documentation.

Who it's for

  • Site managers assessing lone working risks for maintenance workers
  • Security and fire watch personnel working alone on sites
  • Surveyors and inspectors visiting unmanned construction sites
  • Subcontractors working during off-peak hours or weekends

Understand the Fundamentals

Construction Safety Documents Explained

An overview of the key safety documents required on UK construction sites and how they relate to each other.

Key Risks and Considerations

  • •Delayed emergency response — no one to call for help or provide first aid
  • •Violence or confrontation — lone workers in isolated or public-facing locations
  • •Medical emergency — sudden illness with no one present
  • •Equipment failure — becoming trapped or injured without assistance
  • •Mental health — isolation, stress, and anxiety from working alone
  • •Limited welfare access — no nearby facilities on remote sites

Key Features

  • Lone working hazard identification
  • Communication system requirements
  • Check-in procedure templates
  • Prohibited activity lists
  • Emergency response sections

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

Work at height, confined space entry, hot works, work near live services, and any activity involving heavy plant operation should generally not be done alone. Your risk assessment should define site-specific restrictions.

Options include regular phone check-ins, lone worker devices with man-down alerts, two-way radios, and GPS tracking. The choice depends on the site location, mobile signal strength, and risk level.

Check-in frequency depends on the risk level. For higher-risk activities, every 30 minutes is typical. For lower-risk work, hourly check-ins may be sufficient. The risk assessment should define the appropriate interval.

It's the wording from the Management of Health and Safety at Work Regulations 1999. In practice it means the assessment identifies the significant hazards, evaluates who could be harmed, considers existing controls, and is proportionate to the risk — not generic, not exhaustive, but enough to actually inform safer work.

Not always. If the work, site conditions and people are genuinely the same as a previous job, you can reuse a risk assessment — but you must review it and confirm nothing has changed. As soon as the site, scope or team changes, it needs revisiting.
