Zero tolerance to safety negligence! Our people, the public and their property should be kept safe at all times when on or around our worksites. The Tree Guardian works to the standards set out in ISO 45001 Certification – Occupational Health and Safety Management System to ensure we comply with relevant Health and Safety legislation. The Tree Guardian utilises ‘SafetyCulture iauditor’ software in the field to ensure hazard and risk assessments, vehicle checks, incidents and injury reporting are captured, managed and communicated clearly throughout all levels of the organisation.
