Install cable in conduit and associated accessories.
Set up safety barricades, hoarding, safety signs, traffic control cones, directional signs or blinking lights to support traffic control. Ensure that a first aid kit is available for the project. Employ either scaffolding or ladders to access work areas above 1.8 meters in height. Work above this height also requires the use of personal fall arrest systems (PFAS). See fall protection plan on pages 9 and 10 of this document. Install electrical components including: a. 2.5sq mm PVC Insulated cables b. 20 mm diameter PVC conduit c. 13A switch socket outlet d. 20A DP MCB

List of Competent Persons
If the project is to be conducted outdoors, ensure that workers have drinking water and ensure that they are trained in how to recognize heat injuries and perform first aid as needed. This is a list of competent personnel with their hand phone numbers who can be contacted in the event that situations arise that may require their expertise.

#09-2014, ACTIVITY HAZARD RISK ASSESSMENT – FIVE POINT MATRIX EMPLOYED TO QUANTIFY RISK – 7th March 2014 Risk Criteria Severity (1-5, Lowest – Highest)
Likelihood ( 1-5, Lowest Highest)
1-Negligible Injuries: slight injury or health effect, 2-Minor Injuries: Injury or ill health requiring first aid treatment only 3-Moderate Injury: Injury requiring medical treatment or ill health leading to disability 4-Major Injury Disability: serious injury or life threatening occupational disease 5-Castrophic: serious injury resulting in fatality or irreversible health damage with death 1-Rare: very unlikely to happen, 2-Remote: not likely to happen most of the time, 3-Occasional: likely to happen sometime, 4-Major Injury Disability: likely to happen several times regularly, 5-Almost Certain: Likely to happen
Risk Level (Severity x Likelihood) Trivial Risk : 1 to 2 (L) - First aid treatment injury, minor cuts or bruises, clean-up effort for environmental impact Tolerable Risk : 3 to 9 (L) - First aid treatment Injury, minor cuts or bruises, clean-up effort for environmental impact Moderate Risk : 10 to 19 (M) - Temporary disability, lost time injury, outpatient treatment, minor or short term environmental impact Substantial Risk : 20 to 24 (H) - Serious Injury, permanent disability, major disruption and damage to equipment or structure, significant environmental Intolerable Risk : 25 (H) - Fatality or fatalities, serious injury, permanent disability, major structural or equipment damage, detriment environmental
The table above provides numerical methodology to better prioritize hazards. These values are the criteria for the Activity-Based Risk Assessments beginning on the following page. No catastrophic risk of any certainty was identified. 4
Risk is calculated mathematically by multiplying severity of the operation by the likelihood an accident will occur. Generally risk levels calculated at 9 and below are considered acceptable, manageable risk. This does not preclude the need to try and mitigate all risk to the lowest possible level. However, those above nine should receive additional scrutiny to determine what steps are available to reduce overall risk including, administrative controls, substitution of a higher hazardous material for a less hazardous material, use of engineering controls or use of personal protective equipment (PPE).

If a ladder is too short to accomplish the test requiring a height above the 3rd step, management shall provide a ladder capable of reaching a higher height. Use of a man-lift may be an option as well. If it is used it should only be operated by a competent person and must be inspected daily. A man-lift inspection sheet is provided in this document on page 11.

A noise survey may be requested from the Safety Office; however, past experience has shown that this type of drilling to support the installation of these components will not require the use of double hearing protection. To arrange a noise survey contact Mr. Lee Wilson at 8205 8249.

Fall Protection Plan Falls to the ground can occur from unprotected edges and sides of roofing systems, ladders, scaffolding or falls from upper levels during installation of equipment. The order of control measures (hierarchy of controls) to abate falls or to select and use a fall protection method to protect workers from performing work at heights shall be: Elimination Prevention Work Platforms Personal Protection Systems Administrative Controls Primary protection for elevated work consists of a platform or scaffold which is erected properly. The bases are on flat surfaces and secured with braces and guardrails and toe boards are provided on all four sides. The guardrail system shall be capable of withstanding without failure a force of 200 lbs. applied in an outward or downward direction at any point. The top rail shall be 42 +/- 3 inches high and the mid rails shall be installed midway between the top rail and the floor, platform, runway, or ramp. The ends of the top rails and mid rails shall not overhang the terminal posts except where such overhang does not create a projection hazard. Toe boards shall be at least 4 inches high. If there is no fixed empennage stand to restrain workers from falling, workers shall wear an approved personal fall arrest system (PFAS). Personal fall arrest systems include a full-body harness, safety sleeve, 3 foot rope adjuster lanyard, 50 foot lifeline with one free end and a self-locking snap hook at the other, and an anchorage point (D-ring 10
anchorage connector). The anchorage point shall be capable to support at least 5000 pounds per workers. One system per person; each component is essential to restrain movement and prevent falls. Workers will use the rope adjuster to position themselves for a free lateral mobility. Note the PFAS requires conscious effort by each individual to avoid falls from the roof and sides. No employee shall be allowed in the elevated area unless the employee is wearing a PFAS and performing elevated work in that area. Project site safety inspector shall be assigned as the competent person to monitor the safety of other employees. The safety monitor shall be competent to recognize fall hazards, shall warn employees when it appears that the employee is unaware of a fall hazard or is acting in an unsafe manner. The safety monitor shall be in the same area and within visual sighting distance and close enough to communicate orally with the employee being monitored and the safety monitor shall not have other responsibilities which could take the monitor’s attention from the monitoring function. For the Pavilion project ensure that life lines will support at least 5000 pounds. If scaffolding is use, it shall be inspected prior to beginning each pavilion project. The scaffolding shall not be considered a work platform but just an access platform to the top of the pavilion. The scaffolding shall be inspected daily.
