Safety starts with all new employees and contractors being introduced to Crothers Occupational Health and Safety procedures which is step one towards keeping our staff safe on our sites. 


Office of the Federal Safety Commissioner

“Crothers Health and Safety Management System reviewed during the audit was very comprehensive and well structured.  In all, Crothers Management have demonstrated a good understanding of compliance with the Federal Safety Commissioner Audit Criteria. The level of implementation on the project was of a high standard with any evidence requested being provided without any hesitation.  Both Project Management and HSE personnel involved in the audit all demonstrated a good understanding and application of the Crothers Health and Safety Management System and were open to any opportunities to be able to improve their system raised by the Auditor.”
