Subject: # 36 -2014, ACTIVITY HAZARD RISK ASSESSMENT FOR INSTALLING FLOOR TILING AND VINYL FLOOR COVERINGS
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
.
2. This AHA will be reviewed periodically and updated as needed to reflect changes in working conditions, processes or addition of
new materials or equipment.

Housekeeping, cleaning.
Erect protective barricades, safety barriers and or safety tape and post safety signage as needed
to alert all that this is a construction area and access is only for authorized personnel. Preparation
of floor tile or vinyl tile and storing them at work areas.
Laying of floor tiles.
- Application of tile adhesive.
- Cutting of floor tiles for corner, edges or awkward corners.
- Light hammering of placed tiles to get leveling of the finishing floor level
To prepare floor level for vinyl tiles
- Prepare floor level by application of self leveling cement. This will take one day for
cement to cure and dry.
- Sweeping and vacuum of floor to remove cement dust, dirt or debris as much as possible.
- Apply floor adhesive. Most probably solvent base rubber glue onto vinyl tile and floor
surface thinly.
- Putting vinyl tiles onto adhesive applied surfaces.
- Cutting of vinyl tiles for corner , edges or awkward corners
- Rolling finished surface with heavy weight roller to drive out any air bubbles.
Clean work finished area by sweeping , wiping down . Remove unused materials tools and waste
from work area.

#2014-36-2014, ACTIVITY HAZARD RISK ASSESSMENT – FIVE POINT MATRIX EMPLOYED
TO QUANTIFY RISK – JUNE 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)

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).
