Safety first
The briefing, the call sheet and welfare
The AD team runs the floor, so it runs safety on the floor. The producer (as employer) owns the risk assessment; the 1st AD makes sure the whole unit hears it, follows it, and stops when something changes.

The hazards
7What hurts people in this department on UK sets, and what keeps them safe.
- The safety briefingEvery day, and before every hazardous scene, the 1st AD briefs the unit: what is happening, where to stand, who is in charge (stunt coordinator, SFX supervisor, armourer, marine or animal handler) and how the scene will be stopped. Nothing hazardous is changed between rehearsal and take without the specialist and the 1st AD agreeing it.
- Risk information on the call sheetThe call sheet carries the nearest A&E, the unit medic, today's hazards (SFX, stunts, vehicles, water, animals, heights, weather), the closed-set scenes and the weather plan. If it is in the risk assessment, it should be on the sheet.
- Welfare and hoursMeal breaks, rest between days, shelter, toilets, water and warm clothing are safety, not comfort. Long days cause accidents and car crashes on the drive home (Bectu's Eyes Half Shut). Flag overruns to the production manager early.
- Children and chaperonesA child performer needs a licence from their local authority and a licensed chaperone with them at all times. Their hours, breaks and time on set are limited by law. The 2nd AD plans the day around those limits, not the other way round.
- Background artists and the publicCrowd holding areas need shelter, water and a clear route to set. On location, keep pavements passable and members of the public out of the action. Hi-vis and a marshal wherever vehicles move.
- Closed sets and dignityIntimate or nude scenes are closed sets, agreed in advance with the intimacy coordinator and the performers: minimum crew, monitors covered or switched off, no phones. The ADs hold the door.
- Accidents and near missesEvery accident goes in the accident book. Serious ones are reported to the HSE under RIDDOR by the production. Near misses are reported too: that's how the next accident is prevented.
Who is responsible
- The producer (as employer) is responsible for the risk assessment and for competent safety advice.
- The 1st AD runs safety on the floor: briefings, rehearsals and calling stop.
- The 2nd AD puts the risk information on the call sheet and manages cast welfare, children and chaperones.
- The 3rd AD and floor runners lock off, marshal and keep people where the briefing put them.
As a trainee, never
- Never let a scene change after the safety briefing without the specialist and the 1st AD agreeing it.
- Never call action on a hazardous scene until every department has said it is ready.
- Never leave a child performer without their chaperone.
Anyone can say stop. If something feels wrong, say so to your head of department or the 1st AD.
Where this comes from
- HSE: theatre, film and TVThe Health and Safety Executive's guidance for the screen and stage industries.
- HSE: managing risks and risk assessmentWhat a risk assessment is, and the employer's duty under the Management of Health and Safety at Work Regulations 1999.
- HSE: RIDDORWhich injuries and dangerous occurrences a production must report to the HSE.
- The Children (Performances and Activities) (England) Regulations 2014Licences, chaperones, hours and breaks for children on set. Scotland, Wales and Northern Ireland have their own rules.
- Bectu: Eyes Half ShutThe union's campaign on long hours, fatigue and safety in film and TV.
- BFI and BAFTA: bullying, harassment and racism guidanceThe screen industries' shared principles for preventing bullying, harassment and racism.
- CIISAThe Creative Industries Independent Standards Authority: where to report bullying and harassment.
Checked 13 November 2026. This is awareness, not a safety qualification: follow your production's risk assessment and your head of department.

Assistant directors, in detail
What the ADs do
The AD department turns the script into a shooting schedule, then runs that schedule on the floor. The 1st AD runs the set and its safety. The 2nd AD runs the paperwork and the people: cast, supporting artists and the call sheet. The 3rd AD and floor runners keep the floor moving, the cast on time and the set quiet.
Assistant directors are not trainee directors. Some ADs later direct, but that isn't the purpose of the job.
Who the ADs work with
The director first. Then the production manager on the schedule, locations on access and parking, every head of department on timings, and the departments that prepare cast: costume and hair and make-up.
Kit and vocabulary
- Stripboard / shooting schedule: the script broken into days and scenes.
- Call sheet: the next day's plan; the 2nd AD writes it.
- Lock-up: stopping movement and noise around set for a take.
- Background / supporting artists (SAs): extras, directed by the 3rd AD.
- Turnaround: the minimum rest between wrap and the next call.
- Walkie channels: usually one for ADs, one for each technical department.
- Abby Singer and the Martini: the second-to-last and last shots of the day.
How to get in
Most ADs start as floor runners or AD trainees. Experience of events, hospitality or stage management helps: it's people and timings. ScreenSkills publishes a profile and skills checklists for the grades.
Pay: Bectu ADs' card, May 2026.
Where Futures in Film helps
Day One (free, online) covers set etiquette, radios and safety. Then a competency check, and a practical day on our unit with an AD and floor crew. On a production simulation week you can hold an AD grade through prep, shoot and wrap.
