Standard Operating Procedures for Safety

A standard operating procedure, or SOP, is a short written description of how a job should be done. When it is clear and current, it helps everyone do the work the same safe way.

What is an SOP?

An SOP is a set of written instructions for a routine job, listing the steps in order, the safety points and who is responsible. It captures what experienced people know so that new or part-time workers can learn it without guessing.

On a farm, an SOP might cover starting a piece of equipment, moving livestock, cleaning a facility, handling a product or closing the farm at night.

An SOP does not need to be formal. A one-page list with a few photos, clearly written, is often more useful than a long manual.

Why do farms need them?

Without written procedures, each worker develops their own way, and some of those ways skip important steps. When an experienced worker leaves, their knowledge leaves too. An SOP makes the safe way the shared way.

It also helps in training and after incidents. When something goes wrong, you can see whether the procedure was followed and whether it needs to change.

Many farms depend on a few key people who carry the knowledge in their heads. Writing it down protects the farm if someone is ill, injured or leaves, and helps workers share the load.

What should an SOP include?

Keep each SOP to one task and to a page or two at most. Use plain words and short steps. Add photos or drawings where useful.

For machine procedures, the manufacturer's operator manual is the starting point. Refer to it by name rather than copying specifications from memory.

Use short verbs: check, turn off, lock, confirm, ask. Avoid long sentences and jargon that a new worker may not know.

• The task name and who it applies to.
• What training or approval is needed first.
• What to check before starting.
• The steps in order, with safety points beside them.
• What to do if something goes wrong or looks unusual.
• Who to contact, and the reminder to call 911 in an emergency.
• The date and who last reviewed it.

How do you write one that works?

Involve the people who do the job. Watch it done, write it down, and test it by having someone else follow it. If they get stuck, fix the wording.

Avoid the temptation to add everything you can think of. A bloated SOP is not read. Focus on the points that matter for safety and quality.

Test your SOP with someone who has never done the job. If they can follow it and do the job safely under your watch, you are close to finished.

How do you use SOPs in training?

Introduce each SOP in person, at the job. Demonstrate, let the worker try with supervision and check back later. Give the worker a copy or point out where to find it.

Make sure it is available in languages your workers understand. If you translate, have a fluent speaker check the text. A translation error in a safety step can cause harm.

Offer a short refresher whenever an SOP changes, so no one keeps using the old version out of habit.

What about dangerous tasks?

Some tasks, such as work in grain storage, around power take-off equipment, in confined spaces or with chemicals or electricity, are so hazardous that a written SOP is only a start. For these, use official resources, manufacturer information and recognized hands-on training. Do not write rescue or emergency steps from memory.

If you are not sure whether a task should be done at all, or needs a specialist, ask OSHA, extension or your insurance carrier.

Be honest in an SOP about what the task requires, including when a second person must be present and when the job should wait for better conditions.

How do you keep them up to date?

Review every SOP at least once a year, and whenever equipment or methods change. After an incident or close call, check whether a procedure should be updated. Date each version and remove old copies from use.

Invite workers to suggest edits. A procedure that people help shape is more likely to be followed.

Store the current versions in one place, such as a binder in the shop or a shared folder, and tell everyone where it is. Post critical ones at the point of use.
