Subj: #08-2014, ACTIVITY HAZARD RISK ASSESSMENT FOR PEST CONTROL FOGGING OPERATION AT CBRE SINGAPORE POST CENTER
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
pesticide fogging at CBRE Singapore Post Center. This project is projected to be completed tomorrow evening and the actual
fogging will last approximately one hour.
2. The following areas are addressed in this risk assessment:

#08-2014, ACTIVITY HAZARD RISK ASSESSMENT – FIVE POINT MATRIX EMPLOYED TO
QUANTIFY RISK – 20 February 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

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).
