Risk Assessment for Tiling — create with RAMSagent

A Job Hazard Analysis (JHA) for tiling assesses project risks in ceramic and stone laying in wet rooms, kitchens, and common areas. It covers knee strain, silica dust, heavy lifting, and wet room certification according to Canada Labour Code Part II and COHSR.

RAMSagent ensures certifications (BKR, GVK, PER) are included in project documentation.

Typical risks for Risk Assessment — Tiling

Risks, description, and applicable legislation
Risk Description Legal Severity
Knee Strain Tiling involves long periods of kneeling. The project requires rotation, protective equipment, and maximum limits. Canada Labour Code Part II High
Silica Dust Both cutting and grinding floor tiles release dust. Wet cutting is standard, but dry cutting requires H-class extraction. COHSR, Part 3 High
Wet Room Leakage Incorrect waterproofing leads to leaks after months. The project requires certified tradespeople and documentation according to BKR/GVK. COHSR High
Carrying Heavy Materials Tiles, adhesive, grout, and mortar bags can weigh over 25 kg. Mechanical aids are needed from delivery to laying area. Canada Labour Code Part II Medium
COHSR Occupational Health and Safety Management
Systematic occupational health and safety work.
Canada Labour Code Part II Ergonomics
Kneeling and heavy lifting.
BBR National Building Code of Canada
BBR 6:5 moisture safety in wet rooms.

Frequently Asked Questions

What wet room certifications are available?
BKR (Swedish Ceramic Tile Council), GVK (Floor Industry) and PER (painting) are the three largest. Insurance companies often require certified craftsmen — RAMSagent links the requirements in the Job Hazard Analysis (JHA).
How can knee strain be reduced?
Rotate tasks, use electric lift tables for tiles, knee pads with gel inserts, and limit kneeling to a maximum of 2 hours per day according to COHSR.
