SWP: Safe work procedure

A safe work procedure is a written, step-by-step way to do a task so the hazards stay controlled, kept where the crew can read it.

Also calledsafe work practice, safe operating procedure, SWP, work instruction for safety

What it means

A safe work procedure describes how a task is done safely. It lists the steps in order, the hazards that come with them, the equipment and gear needed and what to do if something goes wrong.

It's written once and used many times, which sets it apart from a job safety analysis, which looks at one job at a time. Many sites build a JSA from the safe work procedure for that task and update it for the day's conditions.

Names vary. Safe work practice, safe operating procedure and SOP all show up. Use the name your company uses.

Why it matters

Without a written procedure, every crew does the task its own way, and the one who knew the safe way might be off today. A good procedure holds that knowledge in one place. A bad one sits in a binder that nobody opens, so keep it short and keep it current.

What it looks like on a site

  • A procedure exists for tasks that carry real hazards, such as lockout, hot work or hoisting.
  • It's written with people who do the task, then reviewed by a safety lead.
  • Crews can open it on the job, on paper or on a phone, even with no signal.
  • Workers are trained on it, and the training is recorded.
  • It carries a date and a version, and gets reviewed when the task, the equipment or the rule changes.

Common questions

What is the difference between a safe work procedure and a JSA?
A safe work procedure covers a task that repeats, and stays the same until it's revised. A JSA looks at one job, in one place, with one crew. They work well together.
How long should a safe work procedure be?
As short as it can be and still cover the steps, the hazards and the controls. If a worker won't read it in the field, it's too long.
