Commands and Prohibitions in the Workshop

🧰 Introduction

In a mechanical workshop, it is very important to follow instructions and safety rules. We use commands to tell someone what to do, and prohibitions to tell someone what not to do.
Learning these sentences will help you communicate clearly and safely when operating mechanical tools or machines.

A. Imperative Sentences (Commands and Prohibitions)

Commands are used to give instructions or tell someone to do something.
They usually start with the base form of a verb.
For example:

• Wear your safety gloves.

• Check the oil level.

• Turn off the machine after use.

Prohibitions are used to tell someone not to do something.
They usually start with Don’t + Verb.
For example:

• Don’t touch the hot surface.

• Don’t run in the workshop.

• Don’t use the grinder without goggles.

💡 Remember:
Commands = do something.
Prohibitions = don’t do something.
Both are very important to keep everyone safe in the workshop.
