To make a safety training video, cover one hazard per video and build it around the moment an injury happens: show the ordinary task, the exact point where it goes wrong, why it goes wrong, the control that prevents it, and what to do if it happens anyway. Keep it to 3 to 6 minutes, script it from your real procedure and incident history rather than generic advice, and draw the hazard instead of filming a presenter talking about it. Have someone who does the job and your safety lead check every line. Then treat the video as the briefing before hands-on training and a sign-off, never as a replacement for them.

Why most safety videos do not change behaviour

People do not get hurt because nobody told them electricity is dangerous. They get hurt doing a routine task in a hurry: reaching past a guard to clear a jam, plugging a kettle into an extension lead that is already full, skipping the voltage test because the breaker is "definitely off". A video that lists rules ("always wear PPE", "report hazards") tells people things they already agree with and changes nothing at the moment that matters.

The videos that work show that moment. They take a task the viewer does every week, slow it down, and point at the second where it turns dangerous. The rule then arrives as the answer to something the viewer has just watched, which is why it sticks.

This is a different job from policy training. Explainer videos for compliance training covers turning a written policy into accurate video. A safety video starts from the hazard on the floor, not from the policy document.

The five-part structure, per hazard

Use the same five parts for every hazard. Viewers learn the shape and know where the rule is coming.

Part 4 deserves the most time and the most care. Order the controls the way safety professionals rank them, the hierarchy of controls: remove the hazard if you can, substitute something safer, isolate people from it with engineering controls, then procedures and signage, and only then personal protective equipment. A video that opens with "wear your gloves" teaches the weakest control first and implies it is the main one.

Worked example: electrical safety at work

Here is a five-minute video for office and light workshop staff, not for electricians. At about 150 spoken words a minute that is roughly 750 words of narration. This is the scene list with sample lines.

Scene 1, the task. "Monday morning. The office kettle, a phone charger, a heater and a monitor, all running off one extension lead under a desk." Drawing: a desk, a four-way lead, four plugs, one more plug in the person's hand.

Scene 2, the moment. "Plug in the fifth thing, a second extension lead into the first, and the lead now carries more current than it was built for. Nothing happens. For weeks." Drawing: the daisy-chained leads, the cable under the desk starting to glow faintly.

Scene 3, why. "Current through a cable makes heat. Too much current, or a cable crushed under a chair wheel, makes more heat than the insulation can take. It softens, then chars. That is how a lead starts a fire with nobody touching it." Drawing: a cut-away of a cable, the copper, the insulation browning.

Scene 4, the shock. "The other danger is a damaged cable or a wet appliance. If your body becomes the path to earth, current crosses your chest. A current far smaller than what boils a kettle can stop a heart." Drawing: a frayed cable, a hand, the path drawn through the arm and chest.

Scene 5, the controls, strongest first. "Remove: ask facilities for more wall sockets instead of more leads. Engineer: plug into circuits protected by a residual current device, which cuts the power in a fraction of a second if current leaks. Procedure: one lead per socket, never chained, cables never under rugs or chair paths. Check: look at the plug and cable before you use anything. Scorch marks, exposed wires or a cracked plug mean stop." Drawing: the controls appearing as a ladder, strongest at the top.

Scene 6, the rule for repairs. "If it is broken, label it, unplug it and report it. Do not open it. Anything wired into the building is for a qualified electrician, who isolates it, locks it off and tests it is dead before touching it." Drawing: a 'Do not use' tag on a heater, a padlock on a switch.

Scene 7, if someone is being shocked. "Do not touch them. Switch off the power at the plug or the breaker. If you cannot, call for help and keep others back. Once the power is off, call emergency services and start first aid if you are trained." Drawing: a figure reaching out, a red cross over the hand, then a hand on the switch.

Scene 8, the recap. "One lead per socket. Look before you plug in. Broken means tagged and reported. And never touch someone being shocked until the power is off."

Before this goes out, it gets checked against your site's actual rules and local electrical regulations. Terms vary by country (a residual current device is usually called a GFCI in North America), and your facilities team will know whether your sockets are protected at all. If your workplace has an incident history, put a real (anonymised) one into scene 2. Nothing makes a hazard credible like "this happened in our building last year".

Mistakes that make safety videos ignorable

• Gore for shock value. A graphic injury gets a flinch and then a look away. Show the mechanism clearly instead; a drawn cut-away of a cable or a crush point teaches more than a photograph of the result.
• Everything at once. "Workplace safety" in one 25-minute video means nothing is remembered. One hazard, one video, then a library. What is microlearning explains why short, single-topic pieces get finished.
• The rule without the why. "Do not chain extension leads" is ignored. "Chained leads overheat and start fires behind desks" is not.
• Generic footage. A stock clip of a smiling worker in a hard hat shows nothing about your hazard.
• No check afterwards. A video with no question at the end is passive. Add two or three questions on the specific moment and the specific control.

What video cannot do

Be honest about the limit. A video can explain a hazard and a rule. It cannot teach someone to fit a harness, operate a forklift, or carry out lockout on your machinery; that needs a competent person, the real equipment, and a practical check. Many regulators, including OSHA in the US, expect training to be delivered in a language and vocabulary workers actually understand, and workplaces usually need records of who was trained on what. Use the video as the explanation before the practical session, and keep the sign-off records separately.

If your team works in more than one language, make the video once, then duplicate the project and switch the narration language for a second version, and have a fluent speaker who knows the job check it.

Make it

1. 1

   Pick one hazard from your own site

   Use your incident log, near-miss reports or risk assessment. Choose the hazard that actually hurts people where you work, not the one with the best stock footage.

2. 2

   Write the five parts

   Task, moment, why, controls strongest first, and what to do if it happens. Use the two-column template at /blog/training-video-script-template if you want a format.

3. 3

   Get it checked before you make anything

   Have someone who does the task and your safety lead read every line. Correct terms, local rules and the order of first actions.

4. 4

   Paste the checked script into openCanviz

   Choose Keep my wording so the narration says exactly what was approved, set the length to about five minutes, and pick the whiteboard style so each hazard is drawn as it is explained.

5. 5

   Check every scene against the real workplace

   Pause on each drawing. Equipment, signs and the order of steps must match your site. Fix any scene in the editor without regenerating the rest.

6. 6

   Add the practical and the record

   Show the video before the hands-on session, ask two or three questions on the moment and the control, and keep the sign-off records.

For the wider process of planning a training library, how to make a training video for employees covers the steps around the video itself.

Common questions

How long should a safety training video be? 3 to 6 minutes per hazard. Long enough to show the moment, the mechanism and the controls properly; short enough to be watched at a toolbox talk or before a shift.

Is a safety video enough to meet legal training requirements? Usually not on its own. Requirements depend on your country and industry, but they typically expect training people understand, practical instruction for equipment, and records. Treat the video as one part of the training and check the rules that apply to you.

Should I film real employees or use animation? Film works for showing your actual equipment and site. Animation is better for the moment of injury and the mechanism, which you cannot safely film and which a cut-away drawing explains more clearly. Many teams use both.

How often should safety videos be updated? Whenever the procedure, the equipment or the regulation changes, and after any incident that shows the video missed something. Keeping the script as the source document makes each update a matter of editing text and redrawing the affected scenes.
