Q

Classes of Fire

A

A-D, K

38
Q

occur with ordinary combustible materials, such as wood, papers, or clothing, and require water or water-based solutions to cool or quench the fire to extinguish it.

A

A

39
Q

occur with flammable liquids and vapors, such as paint, oil, grease, or gasoline, and require blocking the source of oxygen or smothering the fuel to extinguish.

A

B

40
Q

occur with electrical equipment and require nonconducting agents to extinguish

A

C

41
Q

occur with combustible or reactive metals, such as sodium, potassium, magnesium, and lithium, and require dry powder agents or sand to extinguish (they are the most difficult fires to control and frequently lead to explosions).

A

D

42
Q

occur with high-temperature cooking oils, grease, or fats and require agents that prevent splashing and cool the fire as well as smother it

A

K

43
Q

Fire Extinguishers types

A

Water Extinguishers
Foam Extinguishers
Carbon Dioxide (CO₂) Extinguishers
Dry Chemical Extinguishers
Wet Chemical Extinguishers
Specialist Extinguishers

44
Q
  • Color: Red
  • Used for: Fires involving solid materials like wood, paper, textiles, and plastics (Class A fires).
  • How it works: Cools the fire by soaking the material and lowering its temperature.
  • Not for use on: Electrical fires, flammable liquids, or metal fires.
A

Water Extinguishers

45
Q

*Color: Cream label

*Used for: Fires involving solid materials (Class A) and flammable liquids (Class B), such as petrol, diesel, and oil.

*How it works: Forms a blanket over the burning liquid, cutting off the oxygen supply and preventing re-ignition.

*Not for use on: Electrical fires unless it’s a specially rated extinguisher.

A

Foam Extinguishers

46
Q

*Color: Black label

*Used for: Fires involving flammable liquids (Class B) and electrical equipment.

*How it works: Displaces oxygen, which smothers the fire and cools the burning material.

*Not for use on: Class A fires, as it does not have a cooling effect, and can lead to re-ignition.

A

Carbon Dioxide (CO₂) Extinguishers

47
Q

*Color: Blue label

*Used for: A wide variety of fires, including solids (Class A), flammable liquids (Class B), flammable gases (Class C), and electrical fires.

*How it works: Coats the fire with a fine powder that separates the fuel from oxygen.

*Not for use in confined spaces: The powder can reduce visibility and may cause breathing problems.

A

Dry Chemical Extinguishers

48
Q

*Color: Yellow label

*Used for: Fires involving cooking oils and fats, typically in kitchen settings (Class F).

*How it works: Forms a foam layer on the burning oil or fat, cutting off oxygen and cooling the fire.

*Not for use on: Electrical fires or flammable liquids.

A

Wet Chemical Extinguishers (Class F)

49
Q

*Used for: Fires involving combustible metals like magnesium, aluminum, and lithium.

*How it works: The extinguisher uses a specialist powder to extinguish metal fires by smothering them.

*Not for use on: Fires involving other types of fuel, as it is specifically designed for metal fires

A

Specialist Extinguishers

50
Q

Are plans for preventing sickness and injury to personnel and damage or destruction of physical assets.

A

Laboratory Safety Plan

51
Q

occurs when harmful microorganisms such as bacteria, viruses, fungi, or parasites invade the body, multiply, and cause disease or damage to the tissues.

A

Infection

52
Q

This can be a bacteria, virus, parasites or prions. Any organism is capable of causing infection if all the links/components are present

A

Infectious agents

53
Q

is the place where an infectious agent lives and reproduces in such a manner that it can be transmitted. Infectious agents can live in or on people, animals, insects, soil or water

A

Reservoir

54
Q

Path by which infectious agent leaves the reservoir

A

Portal of Exit

55
Q

Portal of Exit examples

A

excretions and secretions non‐ intact skin (e.g., draining wounds)

respiratory tract (e.g., sneezing, coughing, talking)

gastrointestinal tract (e.g., vomiting, diarrhea, stool)

mucous membranes (eyes, nose, mouth, vagina)

56
Q

is how the pathogen moves from place to place

A

Modes of Transmission

57
Q

Modes of Transmission

A

Contact transmission
Droplet
Airborne

58
Q

is the most common route of transmission of organisms in health care settings.

A

Contact transmission

59
Q

refers to large droplets that are generated from the respiratory tract of infected individual during coughing, sneezing or laughing or during such procedures as suctioning.

A

Droplet transmission

60
Q

occurs when an individual with an organism/disease that is transmitted by the airborne route expels the organism from their respiratory tract by coughing, laughing, singing and sneezing.

A

Airborne transmission

61
Q

The point where the infectious agent enters a new host lace

A

Portal of Entry

62
Q

is the person who may become infected.
