The photo depicts an employee who was overexposed to silica during manual abrasive blasting with sand and was not provided sufficient respiratory protection. |
An employee performing manual abrasive blasting with sand was overexposed to silica and was wearing an air purifying ¼ mask respirator, which is not sufficient protection. Also, no respiratory protection program had been implemented, including an exposure evaluation, medical evaluation, fit testing, and training. |

Aluminum oxide was substituted as a blasting agent. The employer conducted an exposure assessment and implemented a respiratory protection respiratory protection program.

The photo depicts an excessive accumulation of sand and silica dust on the outside of an abrasive blasting booth where overexposures were identified. |
Employees were at an increased risk of overexposurte to silica from piles of sand and silica dust that were not frequently cleaned-up. The material had accumulated outside of the abrasive blasting booth because the booth was not adequately ventilated or constructed to prevent the escape of the blasting agent (sand). |

|
A new booth and exhaust system was installed and aluminum oxide was substituted as a blasting agent. |

Silica |
The photo depicts silica dust exausted to the outside of an abrasive blasting booth without a dust collection system. |
Air exhausted from an enclosed sandblasting booth, which contained silica dust, was not exhausted through a dust collection system. The dust drifted into the work area, contributing to silica dust overexposures.

A new booth and exhaust system was installed. Aluminum oxide was substituted as a blasting agent.
