Subj: #56-2013 ACTIVITY HAZARD RISK ASSESSMENT FOR THE INSPECTION AND RE-PLACEMENT AS NEEDED OF AFFECTED GRANITE
CLADDING AT SINGAPORE INTERNATIONAL AIRLINES (SIA), UPPER CHANGI ROAD
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
removal of granite cladding to facilitate inspection of the existing underlying brackets that hold the granite in place. Once the
inspection has been completed the granite cladding will be re-instated.
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.

Listing of Competent PNH Personnel
Provide a structural professional engineer (PE), to Inspect the underlying bracket system and report findings to SIA with
recommendations for corrective actions as needed.
Once the report has been received by the embassy and an agreement is reached with regards to follow on needed works, affect
those works to reinstate the affected granite.
Removal of all tools and excess materials to restore the jobsite to normal operational conditions prior to turning it back over to
Singapore International Airlines.
Listing of competent PNH personnel with contact numbers who can be reached for assistance in the event a problem or question
should arise with regards to their particular expertise.
Remove the existing granite cladding to assess the condition of the underlying bracket system that holds the granite in place.

56-2013, ACTIVITY HAZARD RISK ASSESSMENT – FIVE POINT MATRIX EMPLOYED TO
QUANTIFY RISK – 28 September 2013
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)

Moderate Risk :
Substantial Risk :
Intolerable Risk :
1 to 2 (L)
3 to 9 (L)
10 to 19 (M)
20 to 24 (H)
25 (H)
- First aid treatment injury, minor cuts or bruises, clean-up effort for environmental impact
- First aid treatment Injury, minor cuts or bruises, clean-up effort for environmental impact
- Temporary disability, lost time injury, outpatient treatment, minor or short term environmental impact
- Serious Injury, permanent disability, major disruption and damage to equipment or structure, significant environmental
- 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).
