• Abrasive material and the surface being blasted may contain toxic materials that are hazardous to workers, such as lead paint and silica.
• Companies should provide workers with training on blasting health and safety hazards, how to use controls, personal hygiene practices, safe work practices, and personal protective equipment (PPE) and respirator use.
• Companies should provide workers with training on blasting health and safety hazards, how to use controls, personal hygiene practices, safe work practices, and personal protective equipment (PPE) and respirator use.
• Before beginning work, companies should identify the hazards and assign a knowledgeable person trained to recognize hazards who has the authority to quickly take corrective action to eliminate them.
• Using engineering and administrative controls, PPE, including respiratory protection, and training can protect workers involved in abrasive blasting activities.
• Examples of Engineering controls - Changing the way a process flows or the materials used.
• Example of Administrative Controls - Changing the location of where the work is performed.
• Abrasive blasting creates high levels of noise that can cause substantial hearing loss.
• If the process is not completely isolated from the operator, abrasive blasting dusts are a very great health risks.
