Job Hazard Analysis (JHA) Flooring Installation — Knees, Chemicals & Dust Skip to content

Risk Assessment for Flooring — create with RAMSagent

A Job Hazard Analysis (JHA) for flooring installation assesses project risks during the installation of wood, plastic, or tile flooring. It covers knee strain, exposure to adhesives and fillers, silica dust from grinding, and heavy lifting.

RAMSagent aggregates daily knee exposure and heavy lifting per project.

Typical risks for Risk Assessment — Flooring

Risks, description, and applicable legislation
Risk Description Legal Severity
Knee Strain Flooring installation is almost exclusively done kneeling. Projects over 2 hours kneeling/day require an action plan and rotation. Canada Labour Code Part II High
Chemical Adhesives PU and acrylate-based adhesives may contain isocyanates or allergens. Regulated products require medical surveillance. COHSR High
Silica Dust from Grinding Grinding concrete floors before installation is critical for dust — H-class extraction and FFP3. COHSR High
Lifting Strain Tile packages and wood flooring boxes weigh 20–40 kg. Use mechanical aids from unloading area to installation site. Canada Labour Code Part II Medium
COHSR Occupational Health and Safety Management
Systematic occupational health and safety management.
Canada Labour Code Part II Ergonomics
Guidelines for kneeling and heavy lifting.
Canada Labour Code Part II Chemical Workplace Hazards
Regulates adhesives (isocyanates) and silica dust.

Frequently Asked Questions

How can knee injuries be avoided?
Rotate between knee-intensive and standing tasks, use gel-padded knee protection, limit kneeling to 2 hours/day as per COHSR — included in the action plan.
Do I have to use isocyanate-free adhesives?
Not necessarily, but the Job Hazard Analysis (JHA) should evaluate alternatives and justify the choice. Water-based or silane-based adhesives are often equivalent.
