A critical part of the engagement and outreach efforts is to drive improvements through large organizations. This is mainly done through the biz SAFE programme. SMEs are certified through the biz SAFE programme at five levels, depending on their OSH capabilities. Larger companies will serve as bizSAFE partners who commit to engaging bizSAFE-certified SMEs as their clients. Some also serve as mentirs to smaller SMEs to help them improve their bizSAFE certification levels.
