- Check the Blasting Equipment. Look for cracks and other damage.
- Ensure Protective Gear Is Available. Give your blasting workers the proper protective garments.
- Use Proper Cleanup Procedures.
What is the process of sandblasting?
Sandblasting is process of smoothing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air. There are two kinds of sandblasters: “Suction” / “Siphon”” & “Pressure” Blast Systems. There are two basic kinds of sand blasters: Blast Cabinets & Portable Blasters.
How do you prepare for sandblasting?
The first step is to identify the type of material that you are cleaning. This will help you determine the kind of equipment needed for the job such as an air nozzle, a hopper, or a sandblasting gun. The next step is to prepare the surrounding area. Cover all remove anything that does not need sandblasting.
Do you need a respirator for sandblasting?
A supplied-air respirator is required for any blaster working inside a blasting room (see Respiratory Protection below).
Is blasting abrasive hazardous?
Abrasive blasting operations can create high levels of dust and noise. Abrasive material and the surface being blasted may contain toxic materials (e.g., lead paint, silica) that are hazardous to workers. Silica sand (crystalline) can cause silicosis, lung cancer, and breathing problems in exposed workers.
What PPE is required for sandblasting?

How does grit blasting work?
Grit blasting is a process where abrasive particles are accelerated and forcefully directed against a surface. These high-speed abrasive particles remove contaminants from the material’s surface and condition the surface for subsequent finishing.
Do you need primer after sandblasting?
Self etching primers are a very good “shortcut” to replace the phosphate coating protection after sandblasting instead of the time consuming and messy metal treatment process. A good quality self etching primer followed by a good quality 2 part high build (urethane) primer is an excellent foundation for most topcoats.
What primer should I use after sandblasting?
If you’re done doing metal work and are ready to paint or do body filler you can first seal the metal up with a good primer. The top primers for bare metal is Epoxy Primer and Self Etching Primer. Both of these will adhere to the surface and seal out moisture and corrosion.
Can you use a n95 mask for sandblasting?
Respiratory Protection Air purifying respirators and powered air purifying respirators (PAPR’s) are not recommended for abrasive blasting operations but they may be suitable for auxiliary work, such as clean-up operations.
Why is sand blasting banned?
Use of silica: it has been banned in most of the countries including India, because of its different health hazards. Heat generation: This process includes the projection of the particles with high velocity, therefore lots of heat is generated during the process that can harm health and the surface too.
How to maintain your abrasive blasting equipment?
Every blasting chamber, blasting cabinet, ventilating system duct, filtering or cleaning device and item of abrasive blasting equipment should be inspected by a competent person in accordance with the manufacturer’s instructions.
