Subj: #48-2013, ACTIVITY HAZARD RISK ASSESSMENT FOR PESTICIDE APPLICATIONS UPDATED
Ref: (a) Ministry of Health, MH 34:20/24-5 Vol. 4
1. Per reference (a), this risk assessment was completed to address hazards to workers when applying pesticide at the Sembawang
Complex in Singapore. The purpose of this document is to identify specific hazards, indentify those individuals most at risk, evaluate
those hazards for severity and likelihood of occurrence, and recommend corrective actions that will eliminate or minimize hazards to
pest control workers at Sembawang. Bird Control and Snake Control have been addressed in the past, specifically in AHA #26 from
CY 2010 but these operations are conducted very infrequently if at all. The primary pests addressed in this document are
mosquitoes, cockroaches and ants and other crawling inspects, wasps and bees and rodents. This AHA will be reviewed periodically
and updated as needed to reflect changes in working conditions, processes or addition of new materials or equipment. The
following are included as accompanying documents:

ACTIVITY RISK ASSESSMENT – MATRIX EMPLOYED TO QUANTIFY RISK
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

The table above provides numerical methodology to quantify risk and to better prioritize hazard
abatement. These values are the criteria for the Activity-Based Risk Assessments beginning on the
following page. No catastrophic risk of any certainty was identified during the preparation of
this risk assessment.
Generally risk levels calculated at 9 and below are considered acceptable, manageable risk.
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).

WHEN HANDLING ALL PESTICIDES REMEMBER THEY ARE POISONS AND MUST BE TREATED AS SUCH.
ANYTHING WITH A SUFFIX OF “CIDE” AT THE END IS A POISON.
1.
Wash hands and exposed skin thoroughly before meals and after use.
2.
Ensure you have respiratory protection, eye protection, and skin protection
available.
3.
Keep containers tightly closed at all times when not in use.
4.
Control all spills and ensure that spilled materials are kept away from
storm drains as the storm drains at Sembawang ultimately empty into the
straights of Johor.
5.
Avoid inhalation of pesticides, ensure good ventilation whenever working
with these materials.
6. Avoid contact with the skin.
7. Do not contaminate food stuffs, eating utensils or food contact surfaces.
8. Cover all water storage tanks before application.
9. Read the label on all pesticide containers and the accompanying Safety Data
Sheets for all pesticides to be applied. Direct any questions or concerns
to the Safety Officer.
10.
Report any symptoms of overexposure including dizziness, nausea, vomiting,
convulsions, skin and eye irritation.

Discretion is required when planning heavy exercise for acclimatized personnel.
Strenuous exercise and activity for new and un-acclimatized personnel during the first 30 days of heat exposure.
Strenuous exercise should be curtailed for personnel with less than 12 weeks of training in hot weather.
Physical training and exercise should be curtailed for all personnel (operational commitments excluded).
Heat stroke likelihood is high under conditions of high exertion.
