Incident Investigation Basics

After an injury or serious close call, the aim of an investigation is to learn what allowed it to happen and prevent it from happening again. Done fairly, it can protect everyone on the farm.

What is an incident investigation?

An investigation is a structured look at what happened, why it happened and what needs to change. It applies to injuries, illnesses, property damage and close calls. Its purpose is prevention, not punishment.

If someone is hurt, the first priority is always getting help. Call 911 in an emergency. Investigation begins only after the person is safe and cared for.

An investigation does not need to be elaborate to be useful. A short, honest review after a minor injury can reveal as much as a long one after a major event, and it builds the habit you will need if something serious ever happens.

What comes first after an incident?

Make sure the scene is safe for everyone who remains. Make sure the injured person has medical care. Notify the people who need to know, such as family members, a supervisor and, where applicable, your insurance carrier or authorities.

Reporting duties for injuries and deaths exist under various federal and state rules, and they depend on the type and size of the operation. Do not guess. Contact OSHA and your state agency promptly to confirm what applies to you.

Keep contact information for emergency services, your insurance carrier and your local agencies in a place anyone can find. Decide ahead of time who is responsible for calling whom, so that no one has to figure it out in a crisis.

How do you gather information?

Collect facts while memories are fresh. Photograph or sketch the scene if it is safe to do so, and note the equipment, weather and conditions. Talk to the people involved and to witnesses separately and calmly.

Where the incident involved a machine, avoid altering it until you have documented its condition, unless doing so is necessary for safety. If a serious injury or fatality has occurred, authorities may need the scene to stay as it is. Ask them what to preserve.

• What task was being done, and by whom?
• What equipment, tools and materials were involved?
• What were the conditions: weather, light, noise, time of day?
• What training and supervision had the person received?
• Had anything similar happened before?

How do you interview people respectfully?

Choose a private, calm setting. Explain that the aim is to understand and prevent, not to blame. Ask open questions and let people tell the story in their own words. Avoid leading questions or suggesting what they should have done.

People who were injured or who witnessed a serious event may be upset. Be patient, offer support and arrange an interpreter if needed. If someone appears to be in distress, in the United States they can call or text 988 to reach the Suicide & Crisis Lifeline.

How do you decide what to change?

Look beyond the last action before the incident. Ask what conditions, decisions or missing safeguards set the stage. Work, equipment, supervision, training, schedules and communication can all contribute.

Choose fixes that reduce the hazard itself where you can, rather than relying on warnings and reminders alone. Assign each action to a named person with a date.

Be cautious about fixes that depend only on telling people to pay more attention. Where possible, change the equipment, the layout or the procedure so the safe way is the easy way.

What should you record and share?

Write a short, factual summary: what happened, the contributing factors, the actions and who will carry them out. Share the lessons with the crew in plain language, with the injured person's consent where it affects them privately.

Check afterward that the actions were done and that they worked. An investigation that ends with a report on a shelf has not finished its job.

Keep investigation records in a safe place and share them only with those who need them, since they may contain private health or personal details.

How do you support people after an incident?

Injuries and close calls can leave lasting worry or guilt, for the injured person, for coworkers and for family. Check in with those involved in the following days. Allow time off or lighter duties where possible and appropriate. Treat what people share with respect and confidentiality.

If someone is struggling emotionally, encourage them to talk with a trusted person or health professional. In the United States, people can call or text 988 to reach the Suicide & Crisis Lifeline, and should call 911 in an emergency. Avoid pressure to move on quickly.
