Abrasive Blasting Checklist

Abrasive Blasting Safety Checklist

Updated: March 20, 2023

Abrasive blasting is a common process used across many industries, including shipbuilding, automotive, and construction. It’s an effective way to clean surfaces, remove rust, or prepare materials for painting or coating. However, this powerful technique comes with risks that must be addressed through proper safety measures.

The high-pressure nature of abrasive blasting means it requires strict adherence to safety protocols. Workers must wear the right personal protective equipment (PPE), and employers should ensure all equipment is in good working condition. A well-prepared safety plan can help prevent accidents and keep your team safe while maximizing productivity.

In this guide, we’ll walk you through the key hazards associated with abrasive blasting, the essential safety gear you need, and how to properly inspect your tools and workspace before starting a project. Whether you're a seasoned professional or new to the field, following these guidelines will help you stay safe and efficient on the job.

What Is Abrasive Blasting?

Abrasive blasting, also known as sandblasting, involves using compressed air or water to propel abrasive materials at high speed onto a surface. This process is commonly used to clean, strip, or texture surfaces before applying coatings or finishes. It’s a fast and effective method that can save time and effort compared to manual sanding or brushing.

Common Materials Used in Abrasive Blasting

The choice of abrasive material depends on the job requirements and the type of surface being treated. Here are some of the most commonly used options:

• Glass beads: Eco-friendly and free of silica, ideal for light cleaning without damaging the substrate.
• Crushed glass: Aggressive cutting action, great for removing heavy coatings.
• Aluminum oxide: Versatile and suitable for a range of applications, from rust removal to etching.
• Plastic abrasives: Light and non-abrasive, best for delicate surfaces.
• Silicon carbide: Hard and reusable, perfect for fast and efficient blasting.
• Steel shot and grit: Durable and strong, used for heavy-duty tasks like corrosion removal.
• Starblastâ„¢: Uniform blasting patterns, low silica content, and reusable.
• Black Beauty®: Chemically inert and effective for removing coatings from various substrates.
• Ground walnut shells and corn cobs: Biodegradable and gentle, ideal for soft surfaces.

Key Hazards of Abrasive Blasting

While abrasive blasting is efficient, it can pose several risks if not handled correctly. These include exposure to airborne particles, loud noise, high-pressure streams, static electricity, and more. The Occupational Safety and Health Administration (OSHA) has identified the following potential hazards:

• Air contaminants: Inhalation of toxic dust, such as silica, can cause serious health issues.
• Loud noise: Prolonged exposure may lead to hearing loss.
• High-speed particles: Can cause injuries to the skin, eyes, or body.
• High-pressure streams: May result in severe injuries if not handled carefully.
• Static electricity: Improper grounding can lead to electric shocks.
• Vibration: Long-term use may cause hand-arm vibration syndrome.
• Slips and falls: Wet or slippery surfaces increase the risk of accidents.
• Heat exposure: Wearing PPE for long periods can lead to heat-related illnesses.

Essential Safety Equipment Checklist

To reduce the risks involved in abrasive blasting, it's crucial to use the right safety gear. At Finishing Systems, we offer high-quality PPE designed for comfort and protection. Here’s what you should include in your checklist:

• Respirator: Protects against harmful airborne particles. Some models come with built-in hearing protection.
• Climate control device: Helps manage temperature inside the respirator for comfort.
• Eye and face protection: Essential for protecting against flying debris.
• Gloves: Choose durable, anti-vibration gloves to protect hands and forearms.
• Apron or blast suit: Provides full-body protection from abrasive particles.
• Safety shoes or boots: Slip-resistant and reinforced for foot protection.
• Hearing protection: Ear muffs or earplugs to guard against noise levels.

How to Start Every Project Safely

Before beginning any abrasive blasting project, follow a thorough safety procedure. Below is a checklist to ensure your equipment, environment, and PPE are all ready for use:

Blasting Equipment

Your abrasive blasting system typically includes an air compressor, blast vessel, hoses, and nozzle. Before starting, check the following components:

Air Compressor

• Is it maintained and serviced regularly?
• Does it have a pressure relief valve?
• Is it located upwind of the blasting area?
• Is it placed at a safe distance from the blasting equipment?

Blast Vessel

• Is it free of cracks, dents, or corrosion?
• Is it dry and free of debris?
• Has it been properly depressurized before loading abrasive?

Valves, Hoses, and Fittings

• Are all connections secure and leak-free?
• Are there signs of wear or damage on hoses and gaskets?
• Are whip checks and safety pins in place?

Blast Nozzle

• Is the nozzle in good condition?
• Is it sized appropriately for the task?
• Has it worn beyond acceptable limits?

Abrasive Materials

• Are the materials compatible with your equipment?
• Are they free of contaminants or debris?
• Have you reviewed the Material Safety Data Sheet (MSDS)?
• Are they non-toxic or within OSHA’s acceptable limits?
• Are they dry and ready for use?

Objects Being Blasted

• Are they securely fastened?
• Do they contain only non-flammable materials?

Environment

• Is a hazardous zone established?
• Are electrical lines protected?
• Is the site free of tripping hazards?
• Is the area well-lit and ventilated?
• Is the blast machine on level ground?
• Is static electricity controlled?
• Is the atmosphere free of flammable fumes?
• Is the carbon monoxide monitor functioning?

PPE Inspection

• Does the respirator meet NIOSH standards?
• Is it intact and fully functional?
• Are eye protection items undamaged?
• Are gloves and footwear free of tears?
• Is hearing protection available?

Personal Hygiene During Projects

Good hygiene practices are essential to maintaining a safe work environment. Follow these tips:

• Do not eat, drink, or smoke in blasting areas.
• Provide wash stations for frequent handwashing.
• Encourage workers to remove contaminated clothing before eating or smoking.
• Offer showers and change areas at the end of shifts.
• Keep contaminated PPE away from clean zones.
