Ton Plönes (owner of ERT Care), has been in the business for 25 years. He has built up all his knowledge and skills in the field of occupational safety over the past few years and brought them together in the online course of ERT Care. According to him, it’s all about safety and how best to guarantee it. Ton has discovered that training students can be a lot more efficient and effective. In the Netherlands, approximately 500,000 people have been trained as ERT officers. All these people are, for example, responsible for spraying approximately 1 million kilos of CO2 every year during fire drills, which has an enormous impact on the environment. Why are we still doing this?
