Which of the following should never be used to heat a flammable liquid?

Which of the following should never be used to heat a flammable liquid?

Do not heat flammable liquids with an open flame. Steam baths, salt and sand baths, oil and wax baths, heating mantles and hot air or nitrogen baths are preferable. Minimize the production of vapors and the associated risk of ignition by flashback.

Where should you never use or dispense flammable materials?

Never dispense flammable and combustible liquids near ignition sources. Always make sure that metal containers are bonded and grounded when dispensing. Never transfer liquids by pressurizing their usual shipping containers with air.

What materials are flammable?

Flammable: A liquid with a flash point under 10 is considered flammable. Examples: gasoline, acetone, toluene, diethyl ether, alcohols

What describes a substance that is flammable?

Flammable substances are those gases, liquids and solids that will ignite and continue to burn in air if exposed to a source of ignition. It is their vapours combined with air, not the liquid or solids themselves, that ignite and burn.

What should never be used to heat a flammable liquid?

Safe Handling Keep sources of ignition away when handling flammable liquids. Never heat a flammable solvent with a Bunsen burner or other open flame

What can you not use flammable liquids for?

CO2 fire extinguishers are safe for use on flammable liquid and electrical fires. They are NOT for use on wood, paper or fabric fires. They are also NOT suitable for cooking fires that involve oil and grease (such as chip pan fires) as the extinguisher could end up blasting the flames into surrounding areas.

What must be used in heating flammable liquids?

Flammable/combustible liquids must never be heated using open flames. Preferred heat sources include steam baths, water baths, oil baths, hot air baths, and heating mantels. Ignition sources must be eliminated in areas where flammable vapors may be present.

Why flammable liquids must not be heated in an open flame burner?

Keep flammable liquids away from heat and direct sunlight. DO NOT heat flammable liquids directly over a burner or an electrical device that can generate sparks, or has a surface temperature in excess of that which might cause auto-ignition.

Where should flammable materials not be used?

In general, flammable materials must not be stored near exits, electrical equipment or heating equipment. They should always be stored in a separate, well-ventilated storage area, away from potential sources of ignition.

What should you never use flammable chemicals near?

Bulk waste flammable/combustible liquids should be stored in safety cans. Flammables and combustibles must not be stored near oxidizers, corrosives,combustible material, or near heat sources. Make sure all chemicals stored near flammables and combustibles are compatible.

When not in use flammable liquid containers should be?

Handling liquids at point of final use. Category 1, 2, or 3 flammable liquids shall be kept in closed containers when not actually in use. Leakage or spillage of flammable liquids shall be disposed of promptly and safely.

What materials are highly flammable?

Flammable solids often encountered in the laboratory include alkali metals, magnesium metal, metallic hydrides, some organometallic compounds, and sulfur. Many flammable solids react with water and cannot be extinguished with conventional dry chemical or carbon dioxide extinguishers.

What can be flammable?

Besides gasoline and lighter fluid, things like rubbing alcohol, nail polish remover, hand sanitizer and wart remover can easily catch fire. According to the Federal Hazardous Substances Act, all flammable and combustible products must have a warning label.

What best describes a flammable substance?

Flammable substances are defined as substances that will ignite and continue to burn when brought into contact with an ignition source.

What defines flammable?

Definition of flammable : capable of being easily ignited and of burning quickly.

How do you know if a substance is flammable?

Flammability is determined by the flash point of a material. Flash point is the minimum temperature at which a liquid forms a vapor above its surface in sufficient concentration that it can be ignited. Flammable liquids have a flash point of less than 10. Liquids with lower flash points ignite easier.

How do you heat flammable liquids?

CO2 fire extinguishers are safe for use on flammable liquid and electrical fires. They are NOT for use on wood, paper or fabric fires. They are also NOT suitable for cooking fires that involve oil and grease (such as chip pan fires) as the extinguisher could end up blasting the flames into surrounding areas.

Why are flammable liquids not heated using direct heating?

Flammable/combustible liquids must never be heated using open flames. Preferred heat sources include steam baths, water baths, oil baths, hot air baths, and heating mantels. Ignition sources must be eliminated in areas where flammable vapors may be present.

What happens if you heat a flammable liquid?

2 Handling Procedures for Flammable Liquids. DO NOT heat flammable liquids directly over a burner or an electrical device that can generate sparks, or has a surface temperature in excess of that which might cause auto-ignition.

What can you not do with flammable liquids?

Never dispense flammable and combustible liquids near ignition sources. Always make sure that metal containers are bonded and grounded when dispensing. Never transfer liquids by pressurizing their usual shipping containers with air.

What should you not use on a flammable fire?

Never use a water extinguisher on electrical fires or any fire involving a flammable liquid. As any science student will tell you, water conducts the current. If you spray water onto an electrical fire, inadvertently or intentionally, you risk electrocuting yourself.

What are the use restrictions for flammable liquids?

Bulk waste flammable/combustible liquids should be stored in safety cans. Flammables and combustibles must not be stored near oxidizers, corrosives,combustible material, or near heat sources. Make sure all chemicals stored near flammables and combustibles are compatible.

What can I use for flammable liquids?

In the case of a flammable liquid fire, a water extinguisher will spread the liquid around which can potentially do more harm than good and exacerbate the fire. Water extinguishers are recommended for environments that store large amounts of combustible materials such as warehouses, paper mills and storage facilities.

What precautions must be taken when working with flammable liquids?

Safe Handling Keep sources of ignition away when handling flammable liquids. Never heat a flammable solvent with a Bunsen burner or other open flame

Why should flammable liquids be kept away from open flames?

Once vapours from a flammable liquid have ignited, the flames may flash-back. This means the flames travel back, through the vapour- air mixture, to the container or source of the flammable liquid. This can create an explosion. Most flammable liquids produce vapours that are heavier than air.
