What type of hazard is a pyrophoric chemical?

What type of hazard is a pyrophoric chemical?

Pyrophoric chemicals are used in research to catalyze certain reactions and often are incorporated into final products. However, they pose significant physical hazards. They are liquids and solids that will ignite spontaneously in the presence of oxygen and water.

What is a chemical hazard symbol?

A chemical hazard symbol is a pictogram applied to containers of dangerous chemical compounds to indicate the specific hazard, and thus the required precautions. There are several systems of labels, depending on the purpose, such as on the container for end-use, or on a vehicle during transportation.

What is pyrophoric used for?

Pyrophoric materials are substances that ignite instantly upon exposure to oxygen. They can also be water-reactive, where heat and hydrogen (a flammable gas) are produced.

What causes pyrophoric?

What is Pyrophoric Iron? Pyrophoric Iron (FeS) is a form of iron sulfide that combusts on exposure to oxygen; in this case with air. It is formed by reaction of hydrogen sulfide with carbon steel. When a refinery processes sour crude oil, the hydrogen sulfide present in the crude oil causes this problem to develop.

What is this pictogram used for?

Pictograms are graphic images that immediately show the user of a hazardous product what type of hazard is present. With a quick glance, you can see, for example, that the product is flammable, or if it might be a health hazard. Most pictograms have a distinctive red “square set on one of its points” border.

What does this pictogram indicate?

Generally speaking, a pictogram, pictograph or icon are a symbol and/or picture that represents a concept, word or instruction. We see pictograms every day in signs and labels, often in public places.

What does flame pictogram indicate?

What does this pictogram mean? The symbol within the pictogram is a flame with a line underneath it. This symbol indicates that hazardous products with this pictogram can ignite easily and burn rapidly if they are not stored and handled properly.

What is the primary hazard of pyrophoric gases?

The main hazard associated with pyrophoric and water-reactive chemicals is fire upon contact with air or moisture. The high level of reactivity associated with these chemicals requires them to be handled in inert atmospheres, free of ignition sources.

What are pyrophoric materials and their hazards?

Pyrophoric materials are substances that ignite instantly upon exposure to air, moisture in the air, oxygen or water. Other common hazards include corrosivity, teratogenicity, and organic peroxide formation, along with damage to the liver, kidneys, and central nervous system.

What type of glasses should I wear when handling pyrophoric chemicals?

Silane, Diborane, Phosphine Safety glasses that meet the ANSI Z.87 Standard should be worn whenever handling pyrophoric chemicals. Ordinary prescription glasses will NOT provide adequate protection unless they also meet this standard.

How do I dispose of pyrophoric chemicals?

Handling and disposal of pyrophoric chemicals should be in accordance with hazardous waste disposal procedures. Beyond that, removal of potentially pyrophoric material from a glove box may involve quenching material. Check with the principal investigator for assistance with quenching/disposing of waste or email EHS at [email protected]

Can I use a glove box with pyrophoric material?

A glove box may be used with pyrophoric material if an inert environment is required or a glove bag in the event a glove box is not available. The lab principal investigator and/or designated safety officer are responsible for ensuring that you are trained and competent in using a glove box.
