Appendix A – Description of Networks HSEMS
The Networks HSEMS is a tool to help Networks enhance its HSE performance through a structured approach
that drives continuous improvement. The Networks HSEMS also sets out specific HSE roles, responsibilities,
accountabilities and authorities to establish, implement, maintain and improve the HSEMS. Successful implementation of the Networks HSEMS provides senior management with assurance that Networks' HSE risks are being managed. The Networks HSEMS also demonstrates to employees, third parties other stakeholders,
regulators, that Networks is committed to effectively managing its HSE risks.
The framework that Networks has chosen to adopt for its HSEMS is consistent with the requirements of
"OHSAS 18001:2007 Occupational Health and Safety Management Systems-Requirements" and "ISO 14001:2015 Environmental Management Systems-Requirements with Guidance for Use".

iii) engineering controls : designed / built in components of the physical
condition of the workplace(including equipment and structures) to
specifically eliminate or reduce identified hazards;
iv) administrative controls: established specific work instructions , policies and procedures to control unwanted energy flows;
v) personal protective equipment: products designed to be worn on a
worker to control specific hazards.

nonconformity, while a preventive action is taken to prevent occurrence of
nonconformity.

in an injury to a worker or the public.
