Health & Safety

Zero Accident – our goal, our focus, our culture.  

Across our global manufacturing locations the health & safety of everyone on our sites is paramount. The wellbeing of employees, contractors and visitors remains our number one priority.

The zero accident mantra is a mind-set which extends from our leadership team through the entire organisation.

The fundamental steps we follow are:

Engagement: the empowerment, involvement and participation of personnel through routine information, education and training. Embedding the highest ethical standards of behavioural integrity combined with open and honest communication. 

Awareness: we continually reinforce ‘awareness’ and encourage behaviours which self-motivate and ensure a continual journey of learning and improvement. We operate in a manufacturing environment where, by nature of the processes we follow hazards shall be identified and avoided.  We continually review and assess hazards and related risks and from this we take actions to improve health & safety in the work environment. 

Compliance: to embrace, meet & exceed the respective local legislation requirements and the expectations of the Salzgitter Group for health & safety at work.  

Targets: we define occupational ‘safety’ targets which are communicated across the global organisation. We measure, review and challenge our progress.
