Do you want to take the R-DLP exam at CROW? To be well-prepared and transition from DLP to R-DLP, or to retrain according to the CROW 400 guideline, we've developed this exam training course. This practical training course is specifically designed to help you pass the R-DLP exam. It covers gas measurement equipment and the application of personal protective equipment.
Working safely in the soil is not entirely without risks. When working in or with contaminated soil (water), this exam training provides a good foundation, explaining the use of measuring equipment, PPE, and gas measurements. During this training, you will learn to work with hazardous substances that can be present in the soil during excavation and in the air. By performing the correct measurements, you can take appropriate measures to eliminate or manage the risks. You will learn to use the correct measuring equipment to take measurements, thus ensuring a safe workplace. You will also learn to correctly interpret measurement results, how to select the correct PPE, and how to communicate data back to experts.
After completing this training, you will be able to assess future situations and take appropriate measures. You will be able to independently perform measurements, interpret the results (as described by the safety expert), and forward them to the responsible expert. This training is excellent preparation for the CROW R-DLP practical exam. You can register for this exam at CROW Academy website.
The course combines theory and practice. You will learn:
