Lead is a hazardous substance, and if you're working with or around it, you need to be aware of the COSHH regulations and take appropriate precautions. For example, you might need to wear a mask or respirator if you're working with lead dust.
The Lead Academy is an online training course that covers all aspects of health and safety related to lead, including COSHH. It's accredited by IOSH (the Institution of Occupational Safety and Health) and it's perfect for anyone who needs to work with or around.
