Two short safety sessions are common on UK sites: the daily pre-start briefing and the weekly toolbox talk or safety talk. They look alike, with a supervisor, a group of workers and a few minutes standing together. But they do different jobs.
This article explains what a pre-start briefing is, how it differs from a safety talk, how it works in construction compared with manufacturing and other industries, and what to cover in five minutes. You will also find a checklist you can use from tomorrow morning.
What is a pre-start briefing?
A pre-start briefing, also called a pre-start meeting, daily briefing or daily activity briefing, is a short meeting at the start of each shift. It covers what the team will do today, where, with what equipment, and which hazards and controls apply to that work.
It typically lasts 5 to 10 minutes and is led by the supervisor, foreman or section engineer responsible for the work. It is about today's plan: tasks, permits, interfaces with other trades, weather and any changes since yesterday.
What is a safety talk?
A safety talk, more commonly called a toolbox talk in the UK, is a short session on one safety topic, such as manual handling, silica dust or working near overhead power lines. It lasts around 10 to 15 minutes and goes deeper into a hazard: why it matters, what can go wrong and how to control it.
Toolbox talks are usually held weekly or fortnightly and are planned in advance. For a full definition, read what a toolbox talk is and whether it is a legal requirement.
Pre-start briefing vs safety talk at a glance
| Pre-start briefing | Safety talk / toolbox talk | |
|---|---|---|
| Focus | Today's work, tasks and hazards | One safety topic in depth |
| Frequency | Every shift or every day | Weekly, fortnightly or as needed |
| Length | 5 to 10 minutes | 10 to 15 minutes |
| Content | Task plan, permits, interfaces, weather, changes | Hazard, consequences, controls, discussion |
| Preparation | Based on the day's programme and method statements | Planned topic, often from a toolbox talk library |
| Goal | Everyone knows the plan and today's risks | Lasting awareness and safer habits |
| Record | Briefing sheet signed by the team | Toolbox talk register |
In short: the pre-start briefing tells people what is happening today, the safety talk helps them understand why a hazard matters and how to deal with it. Most well-run sites do both.
The UK legal framework for pre-start briefings
No regulation uses the term "pre-start briefing". But several duties make a daily briefing one of the most practical ways to comply.
- Health and Safety at Work etc. Act 1974, section 2: employers must give the information, instruction and supervision needed for safe work.
- Management of Health and Safety at Work Regulations 1999, regulation 10: workers must receive comprehensible and relevant information on the risks and control measures that apply to them.
- CDM 2015: the principal contractor must plan, manage and coordinate the construction phase, ensure a suitable site induction is provided and consult and engage with workers. Contractors must give their workers appropriate supervision, instructions and information. A daily briefing turns the construction phase plan and method statements into instructions people can act on.
The HSE's CDM 2015 guidance explains these duties in more detail.
Pre-start briefings in construction vs industry
The principle is the same everywhere, but the content shifts with the work environment.
On construction sites
Construction sites change every day. Scaffolds move, excavations open, deliveries arrive and several trades work in the same area. A construction pre-start briefing therefore focuses on:
- the activities of the day and where each gang will work
- permits to work: hot works, excavations, confined spaces, lifting operations
- interfaces with other contractors and plant movements
- exclusion zones, traffic routes and changes to access
- weather: wind for cranes and work at height, rain, heat or ice
Subcontractors and agency workers often join the briefing, so clear language and visuals matter.
In manufacturing, logistics and process industries
In a factory or warehouse the environment is more stable, so the pre-start (often called a shift handover or start-of-shift huddle) focuses on what has changed:
- handover from the previous shift: faults, near misses, open actions
- machines out of service, lock-out in place, maintenance work in the area
- production targets, staffing and who is on which line
- temporary hazards: spills, blocked routes, contractors on site
- quality or hygiene points, for example in food production
Because the setting is predictable, these huddles are often shorter, around three to five minutes, and may be held at a board on the shop floor.
What to cover in a 5-minute pre-start briefing
A good pre-start briefing follows the same short structure every day, so nobody has to think about the format and everyone can focus on the content.
- Tasks (1 minute): what are we doing today, where and who is doing what?
- Hazards and controls (1 to 2 minutes): what are the main risks of today's work and the controls from the risk assessment and method statement?
- Permits and equipment (1 minute): which permits are needed, which plant and PPE, and has the equipment been checked?
- Conditions and changes (1 minute): weather, access, other trades, anything different from yesterday?
- Questions and stop rule (30 seconds): does everyone understand, and does everyone know they can stop work if something is unsafe?
Close by asking each person to carry out their own quick check at the workface before starting. In the UK this is often called a point of work risk assessment, a dynamic risk assessment or a Take 5. Read more about this last minute risk assessment.
Pre-start briefing checklist
Use this checklist on a clipboard, a whiteboard or a phone:
- Date, time, location and name of the person giving the briefing
- Today's activities and work areas
- Relevant risk assessments and method statements referred to
- Permits to work in force today
- Plant, tools and PPE required and checked
- Interfaces with other trades or departments
- Weather and environmental conditions
- Changes since the last shift, including near misses and defects
- Emergency arrangements: assembly point, first aiders, rescue plan for work at height or confined spaces
- Questions raised and actions agreed
- Names and signatures of everyone briefed, including subcontractors

How the two work together
Pre-start briefings and safety talks reinforce each other. A recurring issue in the daily briefing, such as people walking through an exclusion zone, is a signal to plan a toolbox talk on that topic. And a toolbox talk on, say, lifting operations makes the next pre-start briefing on a lift much quicker, because everyone already knows the basics.
A practical rhythm for many sites:
- Every day: a 5-minute pre-start briefing per team or gang.
- Every week: one 10 to 15-minute toolbox talk on a planned or topical subject.
- When something changes: an extra briefing or talk the same day.
Frequently asked questions
What is a pre-start briefing?
A short meeting at the start of each shift or day that covers the work planned, the hazards and controls for that work, permits, interfaces and any changes. It typically takes 5 to 10 minutes and is led by the supervisor.
Is a pre-start briefing a legal requirement in the UK?
Not by name. But employers must give workers relevant information and instruction (HSWA 1974 and MHSWR 1999), and on construction projects CDM 2015 requires contractors to give workers appropriate information, instruction and supervision. A daily briefing is a practical way to meet those duties.
Who should lead the pre-start briefing?
The supervisor or foreman directly responsible for the work, because they know the plan and the hazards. On larger sites, the principal contractor often sets the format and checks that briefings take place.
Can a pre-start briefing replace a toolbox talk?
No. A pre-start briefing is about today's work, while a toolbox talk explores one hazard in depth. Most sites need both: a daily briefing and a weekly toolbox talk.
How do you include workers who arrive later or work other shifts?
Brief them individually before they start, or send the briefing to their phone and ask them to confirm they have read and understood it. Make sure late starters are recorded too.
