We’re offering a wide range of Health and Safety qualifications to meet with employment and workplace regulatory requirements, improving conditions and reducing accidents and injuries.
Who needs these qualifications?
Employers are responsible for providing safe and healthy workplace conditions as well as the right systems and methods for safe activities. Nevertheless employees also have a vital part to play in the equation. They need the correct knowledge and the right attitude, which demands proper training in the basics of health and safety, as well as specific training for individual tasks.
