Risk Assessment for Plastering — create with RAMSagent
A Job Hazard Analysis (JHA) for plastering assesses project risks during the removal of existing plaster, mixing of mortar, and plastering against facades. It covers silica dust, alkaline burns, vibration, and falls according to Canada Labour Code Part II and COHSR.
RAMSagent calculates cumulative dust and vibration exposure for the entire project.
Typical risks for Risk Assessment — Plastering
| Risk | Description | Legal | Severity |
|---|---|---|---|
| Silica Dust | Demolition and grinding of plaster generate respirable silica dust. Project level: wet methods as standard, FFP3 as backup. | Canada Labour Code Part II, Section 125 | High |
| Alkaline Burns | Lime and cement mortars have pH >12. Prolonged skin contact causes burns. Use gloves, coveralls, and eye protection. | Canada Labour Code Part II, Section 125 | High |
| Vibration from Chipping | Pneumatic chiselling during demolition causes hand-arm vibration. Daily A(8) accumulates over the project. | Canada Labour Code Part II, Section 125 | High |
| Falls from Scaffolding | Plastering is done from scaffolding class 3–4. Fall risk at edges and during material handling upwards on scaffolding. | Canada Labour Code Part II, Section 125 | High |

Frequently Asked Questions
- Can lime replace cement?
- Sometimes — pure lime mortars are less alkaline but take longer to cure. The risk assessment balances health against the schedule.
- What protection level for chiselling?
- Low-vibration chisel under 2.5 m/s², anti-vibration padded gloves, and max 2 hours/day — included in the mitigation proposal.
