What is the flash point of kerosene?

38-52°C c.c.
Flash point: 38-52°C c.c. The substance can be absorbed into the body by inhalation of its vapour, by ingestion and through the skin. The substance is irritating to the skin and respiratory tract.

Is kerosene a hazardous substance?

exposure can cause burns and itching of the skin with rash, redness and blisters. headache, dizziness, nausea and vomiting, weakness, restlessness, disorientation and drowsiness. Convulsions and coma may follow very high exposure. ► Kerosene may damage the kidneys.

Can kerosene vapors explode?

However, it requires safe storage in fully sealed cans in well-ventilated spaces and should be kept away from sources of naked flame. Kerosene is also not, in standard conditions, an explosion hazard.

Is a kerosene heater safe indoors?

The reason why kerosene heaters should not be used inside houses and other buildings is that the fumes that they emit when burning kerosene are highly combustible. Because of this, it’s possible for a house to catch fire if the heater were to tip over or malfunction (this can also happen with gas heaters).

Is kerosene more flammable than gasoline?

Kerosene is less volatile than gasoline. Its flash point (the temperature at which it will generate a flammable vapour near its surface) is 38 °C (100 °F) or higher, whereas that of gasoline is as low as −40 °C (−40 °F). This property makes kerosene a relatively safe fuel to store and handle.

Does kerosene catch fire easily?

At temperatures above 36 °C, kerosene will produce enough flammable vapours to form a mixture with air that will ignite in the presence of an ignition source.

At what temperature does kerosene evaporate?

Kerosene vapor diffused in air (as from a lamp wick) will burn at a maximum flame temperature of 990 °C (1814 °F). In a stochiometric mixture with oxygen the flame temperature of kerosene can reach 2393 °C (3801 °F).

Is kerosene a fire hazard?

In a kerosene heater, such fuels could start a fire or explode. To avoid the risk of fire even in normal operation you should place kerosene heaters several feet away from all furniture, curtains, papers, clothes, bedding and other combustible materials.

Can a cigarette ignite kerosene?

It’s this vapor that burns when an ignition source (like a lit cigarette) is introduced rather than the fuel itself. Each flammable liquid has a unique flash point. This is the lowest temperature at which enough of the vapor will form above the liquid’s surface to be ignitable.

Can I leave kerosene heater on all night?

Safety Tips for Using a Kerosene Heater Don’t let the kerosene heater run all night; turn it off when you go to bed. You should also turn it off when you leave the building. Don’t hang clothing above the kerosene heater to dry. Go outside or into a garage to fill the tank on the kerosene heater.
