G9- Construction Safety Flashcards
Refers to the practices and procedures implemented to protect workers from injuries and illnesses on construction sites
Construction Safety
Refers to the standards and regulations for the construction industry
OSHA or Occupational Safety and Health Administration
What are the common construction hazards and safety concerns?
- Struck by Accidents
- Falls
- Electrocution
- Structural Collapse
Caused by swinging equipment or falling debris
Struck by Accidents
The leading cause of injuries, often due to unprotected edges, improper scaffold setups, and misuse of ladders
Falls
Risks include contact with power lines and exposed wires
Electrocution
Often linked to excavation issues or improper equipment usage
Structural Collapse
is crucial for safeguarding workers and property
Measures include proper storage of flammable materials, the availability of fire extinguishers, and clear evacuation plans
Fire Safety
What are the Accident Prevention Signs and Tags?
- Danger Signs
- Exit Signs
- Caution Signs
- Safety Instruction Signs
- Traffic Signs
- Directional Signs
- Barricades
Shall be used when immediate hazard exists
Danger Signs
Shall be lettered in legible red letters, not less than 6 inches high, on a white field
Exit Signs
Shall be used to ward possible hazards
Caution Signs
Shall be white with green upper panel with white letters to convey the principal message
Safety Instruction Signs
Construction sites shall be posted with legible traffic signs at points of hazard
Traffic Signs
Shall be white with a black panel and a white directional symbol
Directional Signs
What are the electric hazards in construction?
- Contact with power lines
- Lack of ground-fault protection
- Improper use of tools
Common Scaffold Hazards:
- Falls
- Falling objects
- Collapses
- Electrocution
Common hazards of steel rebars in construction:
Unprotected edges and openings
Improper scaffold setup

can assist drivers in backing up
spotters
allow drivers to see behind them
video cameras
alert drivers to nearby objects
Proximity detection devices (radar/sonar)
can guide drivers and separate workers from moving vehicles
Internal traffic control plans
Pre-planning, proper equipment maintenance, dust suppression, and secure site access are essential
Demolition Safety
Workers must test for hazardous atmospheres, provide adequate ventilation, and use PPE
Confined Spaces
Blasting safety includes:
- Planning and Risk Assessment
- Handling Explosives
- Safety Zones
- Post-Blast
Evaluate the site and design blasts to minimize risk
Planning and Risk Assessment
Store and transport explosives securely with licensed personnel
Handling Explosives
Establish safety perimeters and evacuation plans
Safety Zones
Inspect the area for unexploded ordinance (UNO) and environmental impact
Post-Blast
What are the chemical hazards in construction?
- Asbestos
- Lead
- Silica Dust
- Volatile Organic Compounds (VOCS)
What are the additional safety measures?
- Rollover Protective Structures
- Ladder Safety
- Walking/Working Surfaces
