Both employers and employees have a role to play. Employers need to give us proper training and talk to us about safety. They also must put safety measures in place. We need to communicate well with our team and follow the safety rules. Remember, training, communication, and following safety rules are super important when working in confined spaces. Let’s all work together to keep each other safe!
