The aim of this paper is to show the importance of communicating in English for occupational safety engineers. Communication includes attitudes, emotions, information and ideas which travel from sender to recipient provided the recipient understands them. Communication is a necessary part of everyone's personal life; it is also important in the business world where it is known as business communication. There are two types of business communication: verbal and non-verbal. However, we also distinguish between business communication and everyday communication. Successful business communication in English is the key to success. English is considered a world language and it has become lingua franca in most countries of the world. Furthermore, it is considered language which will ensure us a better job and a more successful career. [1] For quality communication, employee training is not enough; it is necessary to motivate and familiarize oneself with the basics of communication. Communication is a part of everyday life since people are constantly interacting with different cultural groups. The culture of every country has its specific and unique business, that is, professional culture. The key to success is to be familiarized with it. Poorer English language skills can be a barrier to providing or receiving up-to-date information on safety and health at work. In order for occupational safety professionals who do not speak English to receive up-to-date information, outsourcing companies need to establish a well-functioning internal training system. The English language has an important function in the working environment in this respect.
