Conditions that favor fire development or growth
(a)
The result of combustion
(a)
A chemical reaction between oxygen and a combustible fuel
(a)
Source of ignition
(a)
It happens when a hydrocarbon substance unexpectedly create a fire without apparent cause
(a)
The most common class, these fires involve common combustibles such as wood, paper, cloth, rubber, trash, and plastics.
(a)
These Involve flammable liquids, solvents, oil, gasoline, propane, butane, paints, lacquers, and other oil-based products or petroleum-based products.
(a)
Old wiring and space heaters are common causes for residential Class C fires, which involve energized electrical equipment such as wiring, controls, motors, machinery, or appliances.
(a)
It is not common, they can be more difficult to extinguish. They typically involve combustible metals such as magnesium, lithium, potassium, and titanium. This type of fire is more commonly seen in laboratories.
(a)
These are related to combustible cooking materials such as oils and grease commonly found in kitchens. The fires can spread quickly and be the most difficult to manage, especially since water can make the situation worse.
(a)
It only suitable for class A fires. They must not be used for electrical or class K fires. Some water-based extinguishers will have chemical additives to improve their effectiveness but this does not make them suitable for every type of fire.
(a)
They are suitable for fighting class A and B fires. However, they should be used differently depending on the type of fire. For solid combustibles (class A), you can direct the foam directly onto the burning materials. For flammable liquids (class B), the foam should be directed around the burning substance until enough foam has built up to smother the fire. This prevents the risk of spreading flammable liquids by the force of the spray.
(a)
Suitable for class A, B and C fires. They can also be used somewhat successfully for combating electrical fires but there will be a chance of reignition. They're not suitable for class K fires,
(a)
It displace oxygen to smother a fire. This makes them safe to combat electrical fires but hazardous to use in confined spaces where oxygen is limited for the user. Suitable for class B and electrical fires.
(a)
It is designed for class K fires. The firefighting chemicals are discharged at a lower force than other extinguisher types, minimizing the risk of spreading burning oils and fats. It also suited for tackling the high temperatures of burning oils.
(a)
It refers to
systematic efforts to minimize vulnerabilities
and disaster risks, and to avoid, or to limit the
effects of hazards.
(a)
Identifies the hazards;
potential threats are
identified based partly on
experience and records.
(a)
Aims to
establish the magnitude
and the likelihood of the
occurrence of the event.
(a)
Analyzes and identifies
priority subjects (hazards,
areas, and elements at risk)
requiring treatment.
(a)
Identifies the cause of the
risks, identifies and evaluates
treatment strategies, and
prepares and implements
treatment plans.
(a)
Oversees the implementation
progress of the disaster risk
management process. This stage also conducts periodic
investigation of progress and
analysis of impact and
achievement.
(a)
Empowers the people by recognizing and
emphasizing the value of communities and local
organizations. By entrusting DRRM to them, the
technical and organizational capacities of
communities are enhanced.
(a)
Measures undertaken to minimize the long-term risk or
impact of the disaster
(a)
Actions or measure to ensure that the community, organizations, or people can respond effectively once the disaster occurs.
(a)
The entire array of activities aimed at reducing
the severity of the impact of the disaster-causing event which is undertaken before, during,
(a)
Refers to the ability to reduce the probability of failure through
risk reduction measures, to reduce the consequences of failure, and to reduce
recovery time and patterns of vulnerability during reconstruction.
(a)
Capacity to respond or recover quickly from disaster.
(a)
