1 Page 1 of 5 Title Guard against the dangers of electromagnetic radiation while working on telecommunications network structures or sites Level 4 Credits 3 Purpose This unit standard covers the fundamental understanding of the sources and types of electromagnetic radiation, the potential dangers of overexposure, risk assessment and mitigation strategies. People credited with this unit standard are able to: demonstrate knowledge of the sources and types of radio frequency EMR and its associated risks, and methods of detecting and reporting EMR hazards; prepare for work at a telecommunications site with potential EMR hazards; verify and maintain the EMR hazard management plan against an on-site situation; and carry out work in accordance with the EMR hazard management plan. Classification Telecommunications > Telecommunications - Service Delivery Available grade Achieved Explanatory notes 1 This unit standard has been developed for learning and assessment on-job or off-job in a simulated environment. 2 All tasks must be carried out in accordance with the Best Practice Guide (BPG) based on: a quality management systems; b designer s requirements and manufacturers' operating instructions; and government and local government legislation, regulations, bylaws, Health and Safety in Employment Act 1992, Health and Safety in Employment Regulations 1995, and Electricity Regulations 1997; c the most up to date version of the: and all subsequent amendments and replacements; d NZS :1999, Radiofrequency fields Maximum exposure levels 3kHz to 300GHz; AS , Cranes, hoists and winches Safe use Mobile elevating work platforms; ISO 18878:2004, Mobile elevating work platforms Operator (driver) training;

They include legislative and regulatory requirements which may apply across the company or to a specific site. Requirements are documented in the company s health and safety plans, contract work programmes, quality assurance programmes, policies, and procedural documents. Industry practice: those practices that competent practitioners within the industry recognise as current industry best practice. EMR: electromagnetic radiation complementary electrical and magnetic travelling fields. Telecommunications network structures: include poles, towers, masts and any support for radio frequency emitting feeders, and antennae above ground level. 4 Assessment Demonstration of competence in this unit standard must include sufficient experience with EMR situations to satisfy the assessor that the demonstrated skills and knowledge are repeatable. Achievement of this unit standard does not imply that the holder is competent to carry out EMR surveys. 5 Those undertaking assessment against this unit standard must comply with the requirements of the Health and Safety in Employment Act 1992, relevant regulations, and applicable site and company occupational safety and health procedures. For the purpose of this unit standard EMR is restricted to radiation emitted within the radio frequency range, ie 3kHz to 300GHz. Outcomes and evidence requirements Outcome 1 Demonstrate knowledge of the sources and types of radio frequency EMR and its associated risks, and methods of detecting and reporting EMR hazards. 1.1 Define radio frequency EMR 1.2 Identify potential sources of radio frequency EMR. 1.3 Describe the effect of antenna directivity or radiation pattern. 1.4 State the New Zealand permissible public and occupational EMR exposure limits in accordance with NZS :1999.

3 Page 3 of State the candidate s company or organisation permissible public and occupational EMR exposure limits in accordance with the company requirements. 1.6 Describe the potential biological effects of overexposure to EMR in accordance with NZS : Describe the methods for determining EMR levels. personal monitoring devices, documentation, signage, EMR measuring devices, calculations. 1.8 Describe the strategies for eliminating, minimising, or isolating on-site EMR hazards. 1.9 Describe the methods for reporting EMR hazards in accordance with company requirements. Outcome 2 Prepare for work at a telecommunications site with potential EMR hazards. 2.1 Obtain and consult sources of information relating to the site and potential EMR hazards. company records, site owner s documentation, co-location records if available. 2.2 Install and certify job objectives and specifications of equipment to be in accordance with design drawings, installation plans, and equipment manufacturers specifications. 2.3 Produce an EMR hazard management plan for a specific site in accordance with company policy. 2.4 Source and obtain equipment required to support the EMR hazard management plan in accordance with company policy. may include but is not limited to personal protection equipment, personal monitoring devices, EMR measuring devices; evidence of two is required. 2.5 Document the EMR hazard management plan in accordance with company policy.

4 Page 4 of 5 Outcome 3 Verify and maintain the EMR hazard management plan against an on-site situation. 3.1 Review and update the EMR hazard management plan to match the on-site situation in accordance with company policy on arrival at the site. 3.2 Communicate the revised EMR hazard management plan to all personnel on site. Outcome 4 Carry out work in accordance with the EMR hazard management plan. 4.1 Update the EMR hazard management plan in accordance with industry practice in line with circumstances encountered as work progresses. 4.2 Maintain ongoing communication to all personnel regarding amendments to the EMR hazard management plan in accordance with company policy. 4.3 Use a radiation suit is in accordance with manufacturers instructions and industry practice.

Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.

5 Page 5 of 5 Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards. Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
