Hazards and Control: Electrical and Fire Flashcards
it is a serious condition in a construction site that may cause burn skin.
Electrical Hazard
it’s any action, materials and conditions that might increase the size of severity of a fire that might cause ignition.
Fire Hazard
what are the different type of electrical hazard?
- improper grounding
- exposed electrical parts
- damaged tools and equipment
- overhead power lines
it is the process used to eliminate unwanted voltage
grounding
these hazards can cause potential shock and burns.
exposed electrical parts
exposure to damaged electrical tools and equipments can be a risk of ____________.
electrocution
overhead powered and ________ have high voltages which can cause ____________ and electrocution to workers.
energized electrical lines
major burns
what are the different types of fire hazards?
- ordinary combustibles
- flammable liquids
- electrical equipment
- combustible metals
- cooking oil
it is a common materials such as wood , paper, cloth and rubber.
ordinary combustibles
a liquid with a flash point under 100 degree fahrenheit.
flammable liquids
it involves electrical wirings
electrical equipment
________ involve combustible metals, such as _______, _______, and _________.
Fire
magnesium
titanium
sodium
it involves combustible cooking media
cooking oil
What are the steps using a fire extinguisher
Pull the pin
Aim at the base of the fire
Squeeze the lever
Sweep side to side
what are the different type of fire alarms?
- ionisation smoke alarms
- photoelectric (optical) alarms
- ionisation/photoelectric (multi-sensor) alarms
- heat detectors
these detectors are highly sensitive to small amounts of smoke from high-flammable materials like paper and wood, detecting fast-burning fires before they become too thick.
ionisation smoke alarms
it detects larger smoke particles from slow-burning fires, producing reliable results with few-false positives, and are more expensive but more accurate that ionisation detectors.
photoelectric (optical) alarms
These are recommended for all rooms, except kitchens, due to their sensitivity to various fires, faster response, and reduced false alarms compared to single sensor alarms.
ionisation/photoelectric (multi-sensor) alarms
it sensed temperature changes and are non-smoke-sensitive, detecting fires faster than smoke detectors, ideal kitchens, garages, and lofts, they reduce false alarms.
Heat detectors
It is crucial for home and workplace use, preventing accidents and injuries, protective equipment, especially in construction and maintenance industries, has evolved over time.
electrical safety
it is crucial in both work and home settings, as thousands of people die annually due to fires , proper protection and fire fighting equipment ensure maximum protection and safety for firefighters
fire safety
it is crucial for businesses and homes alike, protecting against fires and ensuring safety for both small and large business.
fire extinguisher
It is a fully fire protection system’s primary component . It alerts in case of a fire and directs you to the fire’s exact location
Fire alarms
It release constant, intense water upon a fire alarm, effectively preventing major fires in numerous instances.
fire sprinklers
