Safety first

Exclusion zones, who's in control, and keeping clear

SFX work involves real hazards. Only competent, named SFX crew plan and run an effect, and the person in control of it is in charge of its safety while it runs. Everyone else's job is to know the plan, keep clear and listen.

The hazards

6

What hurts people in this department on UK sets, and what keeps them safe.

  1. Who's in controlThe SFX supervisor plans each effect with the 1st AD and the safety adviser. During the effect, the person in control has the final say. Nobody else changes anything.
  2. Exclusion zonesEach effect has a zone marked out in the briefing. Only the named crew are inside it. If you don't know where it is, ask before you walk on set.
  3. The briefing and the callEffects are briefed to the whole unit, rehearsed, and called clearly. You stand where the briefing put you and stay there until the all-clear.
  4. Rain, wind, smoke and waterEven "simple" effects carry risk: slippery floors, electrics near water, visibility, breathing in smoke or haze. Follow what the SFX crew and the best boy say about kit and cables.
  5. Rigs and pressureSFX rigs can store energy in springs, air and hydraulics. Never touch, step over or move one. It's not a set prop.
  6. Licensed materialsPyrotechnics and explosives are licensed by law and handled only by named, competent SFX crew. Trainees don't handle them.

Who is responsible

  • The producer must use competent SFX crew.
  • The SFX supervisor plans every effect and names who runs it.
  • The person in control of an effect is in charge of its safety while it runs.
  • The 1st AD briefs the unit, rehearses and calls the effect.

As a trainee, never

  • Never enter an exclusion zone, or move a marker, unless the SFX supervisor tells you to.
  • Never touch, move or step over an SFX rig.
  • Never handle pyrotechnics or explosives. They are licensed for named crew only.

Anyone can say stop. If something feels wrong, say so to your head of department or the 1st AD.

Where this comes from

Checked 13 November 2026. This is awareness, not a safety qualification: follow your production's risk assessment and your head of department.

Check yourself

4 situations. Get them all right.

Pass the awareness check. One wrong safety answer means try again. It's practice, and your answers stay on this device.

Question 1: The SFX rain is about to run. You need something from the other side of set and the quickest way is across the wet area.

Question 2: You see a rig with a cable and a box on it near your department's kit. It's in your way.

Question 3: The director wants the smoke thicker for the next take. Who decides?

Question 4: You missed the safety briefing because you were on a run. The effect is next.

Special effects (SFX), in detail

What it does on a UK unit

SFX make it happen in front of camera: rain, snow, wind, smoke and haze, fire, water, breakaway glass and furniture, collapsing sets, moving rigs, bullet hits, explosions. Some are small, like a steaming cup. Some take weeks in the workshop, like a car on a gimbal or a building that falls apart on cue.

Much of it involves real hazards: fire, pressure, water, heavy machinery and explosives. The HSE says the producer must use SFX crew who are competent to plan and safely carry out each effect, and the person in control of an effect has authority over its safety arrangements while it runs (HSE ETIS16). Explosives and pyrotechnics are regulated by the Explosives Regulations 2014, and only nominated, competent SFX crew handle them.

SFX is physical, on the day. VFX is added afterwards. The two plan together.

Who it works with

  • Director and 1st AD: what the effect must do, and when it runs.
  • Stunt coordinator: fire gags, falls, vehicle hits and anything with a performer near an effect.
  • Production designer and construction: breakaways, collapses and rigs built into sets.
  • VFX supervisor: where the physical effect stops and the digital one starts.
  • Health and safety adviser and unit medic: risk assessments, exclusion zones and cover.

How to get in

Most people start as a trainee with an SFX company or a supervisor's crew. Practical engineering is the common background: mechanical, welding and fabrication, electrical, plumbing, carpentry and model-making. Driving licences and plant tickets help. Work comes through SFX companies, many based near the big studios.
