Study Notes
Confined Spaces Hazards
- One key factor that can make a confined space hazardous is poor air quality due to inadequate ventilation or presence of hazardous substances.
- Oxygen deficiency or enrichment is NOT mentioned as a potential risk factor in confined spaces.
Risk Factors and Incidents
- 60% of confined space incidents had written Confined Space Entry Procedures.
- 60% of 'would-be' rescuers died during confined space incidents.
Confined Space Attributes
- 0% of confined spaces lacked a door or opening large enough for safe exit.
- Welding, cutting, or brazing activities can pose risks in confined spaces.
Contributing Factors to Deaths
- A common factor contributing to workers' deaths in confined spaces is the failure to test for hazardous substances.
Air Quality and Fire Hazards
- Poor air quality in a confined space may be due to inadequate ventilation, presence of hazardous substances, or oxygen deficiency/enrichment.
- The presence of ignition sources and flammable substances can lead to a fire hazard in a confined space.
Chemical Hazards
- Residual chemicals and release of supply line contents can cause chemical hazards in confined spaces.
Equipment Hazards
- The text identifies malfunctioning or improperly used equipment as a potential safety hazard in confined spaces.
Behavioral Hazards
- Overconfidence and complacency tend to make workers underestimate the dangers of confined spaces.
