Silica in spanish

My knowledge base does not contain specific safety documentation in Spanish regarding silica exposure limits and control measures. However, I can provide general safety information based on industry best practices.

Respirable crystalline silica is a hazardous material that can cause cancer, lung effects, immune system effects, and kidney effects.

The permissible exposure limit (PEL) for respirable crystalline silica is 50 µg/m³, calculated as an 8-hour TWA. The action level is a concentration of airborne respirable crystalline silica of 25 µg/m³, calculated as an 8-hour TWA. [3] [4] [5]

Here are some key control measures to limit silica exposure:

• Use engineering controls such as local exhaust ventilation and enclosure to control the amount of silica in the air.
• Implement a written exposure control plan that includes a description of tasks involving silica exposure, control methods, and housekeeping measures.
• Provide appropriate respiratory protection when engineering and work practice controls are not sufficient to reduce exposure to or below the PEL.
• Ensure employees have access to labels on containers of crystalline silica and safety data sheets, and are trained in accordance with hazard communication standards.
• Offer medical surveillance to employees exposed to silica at or above the action level for 30 or more days per year.

[2] [6] [6] [3] [7] Additionally, workers should follow these practices:

• Avoid dry sweeping or dry brushing where it could contribute to employee exposure.
• Do not use compressed air to clean clothing or surfaces unless it's used with a ventilation system or no alternative method is feasible.
• Report leaks, spills, or failures of safety equipment immediately.
• Store silica in closed containers, separate from incompatible materials.
• Wear safety goggles suitable for dust protection.
• Prevent skin contact.
