What Is Abrasive Blasting?

Abrasive blasting, sometimes called sandblasting, is a technique that uses compressed air or water to launch a high-pressure stream of abrasive materials at an object. The goal of abrasive blasting may be to clean the surface of an object quickly, remove rust, prepare an object for painting or apply texture.

What Materials Are Used for Abrasive Blasting?

Workers can choose from various materials for abrasive blasting. The type of material they choose largely depends on the coating requirements and the type of application. The following materials are commonly used for abrasive blasting:

  • Glass beads: Glass bead abrasives are made from recycled glass and contain no free silica. This eco-friendly blasting material quickly cleans surfaces without removing too much metal from the substrate.
  • Crushed glass: Crushed glass is made from 100% recycled glass bottles. This abrasive features sharp, rough edges, providing aggressive cutting action ideal for removing heavy coatings.
  • Aluminum oxide: Aluminum oxide is a versatile, medium-density abrasive produced from bauxite. As a blasting material, aluminum oxide can be used in many applications, from rust removal to glass etching.
  • Plastic: Plastic abrasives are a lightweight, silica-free option. Plastic abrasives are less aggressive than other blasting materials and may be the right choice for cleaning softer substrates.
  • Silicon carbide: Silicon carbide is one of the hardest materials available. Silicon carbide enables rapid cutting speeds and short blasting times to prepare surfaces for coatings efficiently. Silicon carbide is also reusable, which can help you cut down on material costs.
  • Steel shot: Steel shot is made to handle challenging, heavy-duty applications. Offering extra strength and durability, steel shot works well for removing rough edges or corrosion.
  • Steel grit: Steel grit features an angular shape and is ideal for forming deep anchor patterns to support coating adhesion. You might apply steel grit in bridge blasting, pipe coating or structural steel applications.
  • Starblast™: Starblast is a general-purpose abrasive material containing a blend of staurolite sands and an extremely low silica level. Its highly uniform blasting patterns distinguish this material, and it also offers reusability and fast cleaning.
  • Black Beauty®: Black Beauty is a popular coal slag product containing less than 0.1% free silica. Available in medium, fine and extra-fine, Black Beauty is a high-quality, chemically inert abrasive that can effectively remove surface coatings from various substrates.
  • Ground walnut shells: Ground walnut shells are an excellent option for applications that require less abrasive materials. This lightweight, biodegradable material effectively and gently removes an object’s topcoat while leaving the substrate unscathed.
  • Ground corn cobs: Like walnut shells, ground corn cobs provide softer, less aggressive blasting. You can use corn cob blasting media to clean and polish everything from jewelry to boat hulls. This material is available in fine, medium and coarse grains.

What Are Some Hazards of Abrasive Blasting?

Abrasive blasting works much faster and is less labor-intensive than sanding an object by hand or cleaning a surface with a wire brush. It’s a critical step in preparing an item for paint or protective coatings. To produce the desired effects, abrasive blasting requires materials that usually create a large amount of dust. Depending on the type of blasting medium used, the dust may be toxic if inhaled. Workers need to protect themselves from air contaminants and various other hazards when using abrasive blasting equipment. The Occupational Safety and Health Administration (OSHA) lists the following potential hazards associated with air blasting:

  • Air contaminants: Exposure to toxic particles in the air is the main health hazard associated with abrasive blasting. Examples of contaminants that may be used as an air blasting material include silica sand, which can cause breathing problems and increase the risk of lung cancer, and toxic metals such as arsenic, lead and nickel.
  • Loud noise: Abrasive blasting exposes operators to noise levels that may lead to hearing loss if they do not wear hearing protection. OSHA’s permissible exposure limit for noise is 90 A-weighted decibels (dBA). Abrasive blasting procedures typically produce 112 to 119 dBA when air is discharged from the nozzle.
  • Powerful particle streams: Operators using abrasive blasting equipment risk being struck by high-speed blasting materials. The abrasive particles may become embedded in the skin or eyes or lead to burns or cuts.
  • High-pressure water or air streams: Operators or others standing nearby could come into contact with high-pressure air or water streams if they are not aware of their surroundings or properly trained. This could potentially lead to severe injuries.
  • Static electricity: Abrasive blasting equipment may generate static electricity. If the equipment is not grounded correctly, employees face the risk of electric shock.
  • Vibration: The prolonged use of abrasive blasting equipment exposes operators to hand and arm vibrations, leading to a condition known as vibration syndrome. Vibration syndrome includes symptoms such as tingling, numbness and pain.
  • Slips: Operators of abrasive blasting equipment are exposed to slippery surfaces resulting from blasting particles. This could lead to slips and falls.
  • Heat: Abrasive blasting equipment operators are at risk of heat-related illnesses due to wearing personal protective equipment (PPE) for long periods or working in hot environments.

You can minimize the risks associated with abrasive blasting by using the right personal safety equipment. At Finishing Systems, we offer reliable, comfortable, high-quality abrasive blasting safety equipment and accessories to protect you and your employees from potential hazards. Here’s the safety gear you’ll want to add to your abrasive blasting checklist:

  • Respirator: A respirator protects an operator from toxic particles in the air. We carry a range of air-supplied respirators to suit the job. We also offer a respirator with built-in hearing protection within the helmet to further protect your operators.
  • Climate control device: You can help prevent prolonged exposure to heat and heat-related illnesses with a climate control device. For example, the RPB® C40™ Climate Control Device combines a lightweight belt and a simple lever to cool or warm the temperature inside a respirator easily, so an operator can work comfortably and safely no matter where they are.
  • Eye and face protection: Workers around an abrasive blasting area should also protect themselves with proper eye protection.
  • Gloves: Choose heavy-duty RPB safety gloves made of durable material, like canvas or leather, that protect the entire forearm. The material should be designed to prevent particle abrasion. Also, consider choosing gloves designed to reduce the impact of vibrations.
  • Apron or blast suit: Workers need to protect their bodies from abrasive particles by wearing an apron or coveralls. For maximum protection, consider a breathable but heavy-duty blast suit that protects the arms and the front of the body.
  • Safety shoes or boots: Footwear should protect operators from particulate matter and be made of tough material. Steel-tip boots are durable and protect toes from falling objects and punctures. Look for features like slip-resistance as well.
  • Hearing protection: If your respirators do not include hearing protection, it’s crucial employees wear comfortable ear muffs or properly rated earplugs to protect their hearing.

How to Begin Every Project Safely

Every abrasive blasting project should begin with a safety procedure to ensure the equipment is ready for proper use. Below you’ll find a checklist to help you and employees inspect your blasting equipment, surroundings and PPE for safety.

Blasting Equipment

The typical abrasive blast system consists of an air compressor, air supply hose, abrasive blaster, blast hose and blast nozzle. All of these components work together to deliver a powerful stream of abrasive material. Before you start working, inspect the following abrasive blasting components:

Air Compressor

An air compressor powers the abrasive blasting equipment. Consider the following before you begin:

  • Is the air compressor maintained and serviced?
  • Is it equipped with a pressure relief valve?
  • Does the air compressor meet your air supply requirements?
  • Is the air compressor located upwind of blasting operations?
  • Is the air compressor at a safe distance from the blasting equipment?

Blast Vessel

The blast vessel, also called the pressure vessel, is the tank filled with compressed air and the abrasive material. Answer the following:

  • Is the inside and outside of the blast vessel free of corrosion, cracks, dents, bulges or other forms of damage?
  • Is the inside of the blast vessel free of moisture and debris?
  • Does the blast vessel contain any leaks?
  • Has the blast vessel been depressurized before loading the abrasive?

Valves, Hoses, Pipes, Wires and Fittings

Your machine’s parts undergo a lot of stress during blasting applications, so it’s critical to check these components for wear and tear regularly. Ask yourself the following questions:

  • Are all valves, hoses, pipes, wires and fittings in good condition and free of leaks, cracks, holes or other damage?
  • Are there any soft spots in the blast, air or remote control hoses?
  • Are blast and air hose gaskets free of leaks and visible wear?
