Always make sure that you’re wearing safety gear like goggles, gloves, steel-toed boots, hardhats, etc. Many toes and fingers have been saved by outfitting the workers with quality gear. You can never be too careful.
If you are not properly trained or qualified to perform a specific task, don’t perform it. Let your manager know that you’re not qualified to perform the task and that they should find someone else to do it and that you would love to get trained in the meantime. If you have been injured at the workplace, you would benefit from speaking with a personal injury attorney Seattle who can provide you with guidance through the legal process.
