What is meant ignition source?
A source of ignition can be described as, “any object, process or event capable of igniting or transmitting a medium to prompt combustion”. Within this definition, a source of ignition could include open flames, hot surfaces, friction, sparks and static electricity.

What are ignition sources OSHA?
Ignition sources can include any material, equipment or operation that emits a spark or flame—including obvious items, such as torches, as well as less obvious items, such as static electricity and grinding operations.
Is smoking an ignition source?
The fundamental thermal properties of a burning cigarette have long been studied in an attempt to understand the formation and chemical composition of smoke. As described below, however, the resulting knowledge is intrinsically linked to the propensity of cigarettes to act an ignition source.
Is heat an ignition source?
Ignition sources include hot surfaces, electricity (including static electricity), flames, and sparks.
Is a diesel engine an ignition source?
Internal combustion engines, whether fueled by gasoline, diesel, propane, natural gas, or other fuels, can act as ignition sources. Examples include: Stationary engines such as compressors, generators and pumps.
What is the sources of ignition at home?
IGNITION SOURCES Smokers’ material – such as cigarettes, matches and lighters. Naked flames – such as candles or gas open-flame equipment. Heaters – electrical, gas or oil-fired (fixed or portable) Hot processes – such as repair work by contractors.
Is sunlight an ignition source?
An ignition source provides the initial heat (energy) required to initiate combustion. Flames, electrical sparks, light, or hot objects (radiant heat) can start a fire. Example sources: Light – sun, laser.
Is a car an ignition source?
Internal combustion engines, whether fueled by gasoline, diesel, propane, natural gas, or other fuels, can act as ignition sources. Examples include: Emergency response vehicles such as fire engines and ambulances.

What is the ignition source of fire?
Ignition Sources. The following discussion addresses the most frequently encountered sources of ignition.
Which of the following are ignition sources?
Many sources of ignition exist, including open flames, hot gases, hot surfaces, mechanical sparks and electrical sparks, among others. In the process of ignition, once a propagating flame is provided enough energy from an ignition source, it turns into a self-sustaining flame.
What is an ignition component?
Ignition Component ( IC ) (A component of the NFDRS-National Fire Danger Rating System) The Ignition Component is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex.
