Subject: #09-2014 ACTIVITY HAZARD RISK ASSESSMENT FOR INSTALLATION OF CONDUITS AND CABLES
FOR T2 MASTER CLOCK
Ref: (a) Ministry of Manpower Regulations Regarding General Safety and Health 354A
1. Per reference (a), this risk assessment was completed to identify hazards that pose risk to workers,
evaluate those hazards for severity and likelihood of occurrence, and recommend corrective actions that
will eliminate or minimize hazards associated with the installation of conduits & cables for T2 Master Clock
2. This AHRA will be reviewed periodically and updated as needed to reflect changes in working
conditions, processes or addition of new materials or equipment.

Process Description Work Activities
1 Deliver materials to job-site Deliver tools, materials, lift equipment as needed, equipment for working at height etc.
2 Site preparation 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.
3 Working at Height 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.
3 Install cable in conduit and associated accessories.
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
4 Working in heat 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.
5 List of Competent Persons 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 – 7
thMarch 2014
Risk Criteria
Severity (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
Likelihood ( 1-5, Lowest -
Highest)
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.
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).

Safety Manager 2 Working at Heights either using scaffolding or ladders. Falls Persons working at height or persons transiting the area where work at height is being performed. If scaffolding is being used, it shall be inspected by a competent person. If work is being conducted above 1.8 meters (six feet) workers shall wear safety harnesses. All ladders shall be inspected prior to being used for overall condition, foot treads, step treads and presence of debris on steps. In no instance shall a workers stand on a ladder above the third step from the top.
3 2 6 PNH employs a generic fall
protection plan that can be used as a reference or tailored to a specific job. A copy of this plan is included on page(s) 9 & 10 of this document. 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.

Hearing protection is provided to all PNH workers and they receive training on the correct use of this equipment and the hazards of working unprotected around loud noise sources.
2 2 4 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. Project Manager and Senior Safety Manager
