Dangerous Goods Class 5: Oxidizing Substances and Organic PeroxidesPosted in Dangerous Goods - 3 Feb 2020, 10:36 AM
Oxidizing substances and organic peroxides are put in the same group, albeit as different divisions. The two substances have hazard potentials because they contain carbons and yield or generate oxygen. The resulting chemical reactions can cause ignition or combustion. They also have corrosive effects, which can be dangerous for materials and living creatures.
Examples of Oxidizing Substances and Organic Peroxides
Type 5.1 covers various types of oxidizers that yield oxygen. They can come in solid and liquid forms. Type 5.2 covers various types of materials that contain oxygen in its chemical structures. It means that organic radicals have replaced some of the hydrogen atoms.
Examples of materials from these categories include potassium permanganate, hydrogen peroxide, sodium nitrite, ammonium nitrate, and all oxygen generators. Typical products that may contain them are hair coloring and fertilizer.
Both types are signified with slightly different placards. Oxidizing substances are symbolized with a black flame surrounding a large “O”, with number 5.1 underneath and yellow background. Meanwhile, the organic peroxides have a black or white flame with red and yellow background, plus a number 5.2 underneath.
Standard Storing Methods for Dangerous Goods Class 5
Dangerous Goods Class 5 are highly reactive, with a high level of damage that can happen if they are ignited. Suppliers and manufacturers must follow strict safety standards when storing these materials. The storing method must follow these principles:
- Properly ventilated
- Away from boilers, hot steam, direct sun exposure, and other heat sources
- Away from hot surfaces, open flames, sparks, and other ignition sources
- Using a proper temperature that prevents ignition or combustion
- Properly marked and labelled
All dangerous goods from this class must have several emergency systems and fire safety equipment nearby. Workers must also have quick emergency access when these dangerous goods cause fire.
Transfer Procedures for Oxidizing Substances and Organic Peroxides
Dangerous Goods Class 5 are quite difficult to contain once they catch fire. Since they contain oxygen, the reaction after ignition can be quick and hazardous. They must be contained in enclosed, isolated containers with temperature controller. Organic peroxides must be stored in a refrigerated container, which prevents chemical reactions caused by rising temperature.
There are several safety standards used to transfer Dangerous Goods Class 5, which are:
· Proper Identification
Each container must have complete identification elements, such as the name of the goods, danger, precautions, hazard risks, proper labelling, and such. They must follow the standard identification that is officially followed by the country.
· Proper Packaging
The containers must be in good condition, providing insulated and enclosed storage space for dangerous goods. They must follow the quality standard and be regularly checked. All containers that no longer have good quality must be discarded.
· Proper HAZMAT Training
Everyone involved in the handling of the dangerous goods must follow thorough HAZMAT training respective of their jobs. All aspects of the transporting, from the first loading to the last, must be done by trained staff. The driver must have a valid driver’s license and undergo routine health checks. Air and water transports must follow the official regulations.Oxidizing substances and organic peroxides have dangerous risks, which require proper storage, handling, and transporting methods. Make sure everyone involved follow the official regulations thoroughly.
