Red Garnet User Safety
Red Garnet is a safe, ecologic and stable material. It does not need special attention while handled. Wearing personal protection equipment is necessary, as well as avoiding eye contact. Storing this material does not require special conditions. All it needs is a good air ventilation in the storage space.
In case of inhalation, the affected person must be taken out, to fresh air, and kept in a comfortable position so he/she can breathe properly. If he/she has difficulties breathing, oxygen can be administered. If he/she stops breathing, CPR manoeuvres can be performed. In this case, a medical intervention is also necessary.
Avoid direct contact with the skin. If your skin entered in direct contact with this abrasive material, you must wash the affected area with clean water for 20 minutes. Use a soft soap and clean water.
In case of ingestion, a doctor’s intervention is necessary. All treatments applied to the victim must take into account the symptoms showed by that victim.
Avoid walking through the material and always wear personal protective equipment. In case of leakages, one must insulate the area on an approximately 25 meters radius in all directions. It is forbidden to spill this material in water. Please avoid dust. Use professional vacuum cleaners to clean the area.
This material comprises silicate crystals and/or quartz. According to the IARC Monographs for assessing the hazards posed by chemical substances to people, this material bears a potential risk of cancer.

Red Garnet Application
Auto Industry
In the production of automotive components, such as body chassis or aluminum and steel parts, waterjet cutting with red garnet can be used to make precise and accurate cuts. Thus, problems associated with the thermal deformations that can occur in the thermal cutting processes are avoided. This is essential for automotive components, where the structural integrity is crucial.
Aerospace Industry
In the production of aerospace components, advanced waterjet cutting techniques are used to cut non-ferrous or hard metals such as titanium or special alloys. In addition, composite materials such as carbon fibers or glass-reinforced thermosetting plastic are used. Red garnet waterjet cutting offers an efficient solution for cutting these materials without affecting their mechanical properties.
The renewable energy Industry
In the production of components for equipment used in the renewable energy industry, such as wind turbines or solar panels, water jet cutting is used to make accurate cuts in composite and metallic materials. Red garnet provides the ability to cut tough materials, helping to make energy efficient components for renewables.
