AUGUST CHEMICAL OF THE MONTH – Sodium Metasilicate Anhydrous

Sodium metasilicate anhydrous is a white alkaline powder used in industrial cleaners and cement manufacturing. It can cause severe chemical burns on contact with skin and is therefore classified as Corrosive.

Most model codes limit the indoor storage of Corrosive solids to 5,000 pounds. The storage amount can be increased or decreased based on storage configuration, floor level, and presence of fire sprinklers. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements. TheHazMatApp is available for free at the Apple App Store and Google Play.

JUNE CHEMICAL OF THE MONTH – Trisodium Phosphate

Trisodium phosphate (TSP) appears as a white solid. It is used as a cleaning agent in a variety of consumer-grade soaps and detergents. It is also used as a food additive for moisture retention and emulsification. Pure trisodium phosphate is classified as Corrosive.

Most model codes limit the indoor storage of Corrosive solids to 5,000 lbs. The storage amount can be increased or decreased based on storage configuration, floor level, and presence of fire sprinklers. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements. TheHazMatApp is available for free at the Apple App Store and Google Play.

MAY CHEMICAL OF THE MONTH – Hydrogen Peroxide 34%

Hydrogen peroxide 34% is a highly concentrated, industrial-strength oxidizer. Its uses include commercial cleaning/bleaching and water treatment. It is classified as Corrosive, Unstable Reactive Class 1, and Oxidizer Class 2. Since there are multiple hazard classifications, the most stringent will apply when determining the maximum allowable quantity (MAQ).

Most model codes limit the indoor storage of Oxidizer 2 liquids to 250 pounds. Facilities storing or utilizing hydrogen peroxide can increase the allowable amount by providing fire sprinklers, approved storage cabinets, and multiple control areas. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements. TheHazMatApp is available for free from the Apple App Store and on Google Play.

APRIL CHEMICAL OF THE MONTH – Acrylonitrile

Acrylonitrile is a liquid used primarily in producing ABS plastics, acrylic fibers, and nitrile rubber. It is classified as Flammable Liquid Class IB, Unstable Reactive Class 2, and Toxic. Since there are multiple hazard classifications, the most stringent will apply when determining the maximum allowable quantity (MAQ).

Most model codes limit the indoor storage of Unstable Reactive Class 2 liquids to 50 pounds. Facilities storing or utilizing acrylonitrile can increase the allowable amount by providing fire sprinklers, approved storage cabinets, and multiple control areas. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements. TheHazMatApp is available for free from the Apple App Store and on Google Play.

MARCH CHEMICAL OF THE MONTH – Potassium Dichromate

Potassium dichromate appears as a red colored solid and is used in wood preservatives and in the manufacture of pigments. It is classified as Corrosive, Toxic, Unstable Reactive Class 1, and an Oxidizer Class 1. Since there are multiple hazard classifications, the most stringent will apply when determining the maximum allowable quantity (MAQ).

Most model codes limit the indoor storage of Toxic solids to 500 pounds. Facilities utilizing potassium dichromate can increase the allowable amount by providing fire sprinklers, approved storage cabinets, and multiple control areas. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements.

JANUARY CHEMICAL OF THE MONTH – Manganese Dioxide

Manganese Dioxide appears as a black/brown powder. Its uses include the production of dry-cell batteries and as a pigment for coloring glass and ceramics. It is classified as Oxidizer Class 1 and a Combustible Dust.

Since it is classified as an Oxidizer and Combustible Dust, a detailed code analysis should be performed to ensure proper storage and use. Use of manganese dioxide may also require a Dust Hazard Analysis (DHA). Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements.

DECEMBER CHEMICAL OF THE MONTH – Sodium azide

Sodium azide is an inorganic compound utilized in many car airbag systems. An electrical charge is triggered by an automobile impact that causes sodium azide to explode and convert to nitrogen gas inside the airbag. Sodium azide is classified as a Water Reactive Class 2, Unstable Reactive 3N, and Highly Toxic. Since there are multiple hazard classifications, the most stringent will apply when determining the maximum allowable quantity.

Most model codes limit the indoor storage of Unstable Reactive Class 3 (non-detonable) to only 5 pounds. The storage amount can be increased or decreased based on storage configuration, floor level, and presence of fire sprinklers. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements. TheHazMatApp is now available for free at the Apple App Store and Google Play.

November Chemical of the Month – Cheesecake Flavoring

Cheesecake flavoring has a variety of uses as a food and drink additive. When stored in its concentrated form the flavoring has a flash point of 176F and is also considered corrosive. The flash point classifies the flavoring as a Combustible Liquid Class IIIA in addition to being classified as Corrosive. This could present a challenge for bulk storage of this flavoring as well as other flavors with the same hazard classifications. Since there are multiple hazard classifications, the most stringent will apply when determining the maximum allowable quantity (MAQ).

Most model codes limit the indoor storage of Combustible Liquid Class IIIA to 330 gallons. The storage amount can be increased or decreased based on storage configuration, floor level, and presence of fire sprinklers. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements. TheHazMatApp is available for free from the Apple App Store and now also on Google Play.

OCTOBER CHEMICAL OF THE MONTH – Trimethylaluminum

Trimethylaluminum (TMA) is a pyrophoric (ignites when exposed to air) liquid used primarily in semiconductor manufacturing. TMA is also classified as an Unstable Reactive Class 2, Water Reactive Class 3, and Corrosive. Since there are multiple hazard classifications, the most stringent will apply when determining the maximum allowable quantity.

Most model codes require fire sprinklers in any buildings storing or utilizing pyrophorics. Additionally, the allowed storage quantity is less than 1 gallon before Group H occupancy provisions or other hazard mitigation features must be followed. Remember to always thoroughly review your SDS and check your local codes before implementing any hazmat code requirements.
