Study Notes
Falls
- Leading causes of death in construction include electrical incidents, struck-by incidents, caught-in or caught-between incidents, and falls.
Safety Instruction Sign
- A sign with a white background and green panel with white lettering indicates safety instructions.
Oily Rags Disposal
- Proper disposal of oily rags requires they be stored in a container designed for that purpose.
Housekeeping
- Maintaining a clean work area free from scraps or spills is defined as housekeeping.
Hazardous Materials
- HAZCOM identifies paint, concrete, and wood dust as hazardous materials.
Reporting Hazards
- Under HAZCOM, spotting a hazard on the job site necessitates reporting it to your supervisor.
Electrical Equipment
- Metal ladders should not be used in proximity to electrical equipment to prevent accidents.
Ladder Placement
- The base of a straight ladder leaned against a 16-foot wall should be positioned 4 feet away from the wall's base.
Scaffold Types
- The basic types of scaffolds used in construction are self-supporting and suspended scaffolds.
Stacking Materials
- Proper interlocking of stacked materials requires placing objects at right angles.
Maximum Height-to-Base Ratio
- To mitigate risks of falls, the maximum height-to-base ratio for stacked materials should be 4:1.
Equipment Rollover
- Equipment rollover is the most common cause of death among equipment operators.
Cave-in Risks
- Most cave-ins occur suddenly, typically in trenches 5 feet to 15 feet deep.
Trench Exit Requirement
- Trenches exceeding 4 feet in depth must have an exit every 25 feet.
Spoil Pile Distance
- A spoil pile must be at least 2 feet from the edge of an excavation to ensure safety.
Trench Protection
- Shoring is the method used to prevent trench wall cave-ins.
Protective Guards
- Power tools and machines are equipped with protective guards to prevent worker injuries from rotating or moving parts.
Safe Working Distance
- The minimum safe working distance from exposed electrical conductors varies depending on the voltage involved.
Proximity Work
- Work performed close to a hazard, without direct contact, is classified as proximity work.
Energy-Isolating Devices
- Examples of energy-isolating devices include circuit breakers and disconnect switches.
Self-Contained Breathing Apparatus
- The self-contained breathing apparatus is a respirator that supplies its own clean air.
Exposure to Hazardous Materials
- Exposure to hazardous materials can occur through inhalation, ingestion, and absorption.
Hypothermia
- Hypothermia is caused by prolonged exposure to cold temperatures.
Cylinder Separation
- Oxygen and fuel cylinders must be stored at least 20 feet apart when in storage.
Fire Risks from Grease and Oil
- Grease and oil must be kept away from oxygen tanks as they can cause explosions.
Fire Triangle
- The presence of oxygen, heat, and fuel simultaneously is necessary for fire formation.
Electrical Fire Extinguishing
- A fire extinguisher labeled "C" is suitable for extinguishing electrical fires.
Confined Space Characteristics
- Confined spaces typically have limited ventilation, posing potential hazards to workers.
