**New OSHA Silica Exposure Rules**
*Updated: December 22, 2023*
Exposure to crystalline silica has long been recognized as a serious health risk. Crystalline silica is found in many construction materials like sand, stone, concrete, and mortar, and it can become airborne during common tasks such as cutting, grinding, or drilling. To better protect workers, OSHA has updated its standards to reduce permissible exposure levels.
At Finishing Systems, we prioritize the safety and well-being of our employees and our customers. Staying informed about regulatory changes is essential for maintaining a safe working environment. If you have any questions about the new silica rules or need guidance on how to comply, we recommend visiting OSHA’s official website or using their On-Site Consultation Program. This program offers expert advice to help identify and reduce workplace hazards, including silica exposure.
The updated OSHA standards apply to two main groups:
1. **Construction workers** – These rules have been in effect since September 23, 2017.
2. **General industry and maritime workers** – These became effective on June 23, 2018.
These standards are designed for workers who handle loose silica products or perform tasks that generate respirable silica dust, such as blasting, abrasive work, or masonry activities.
### What Is Crystalline Silica?
Crystalline silica is a naturally occurring mineral found in Earth's crust. It is commonly used in construction materials like sand, stone, and concrete, and is also present in products such as glass, ceramics, and pottery.
There are several forms of crystalline silica, including:
- **Quartz**: The most common form, widely found in rocks and soil.
- **Cristobalite**: A less common form, often found in volcanic rock or formed when quartz is heated.
- **Tridymite**: Rare and typically not encountered in typical workplace settings.
When these materials are disturbed—such as during cutting or grinding—fine particles can become airborne and be inhaled, leading to serious health issues.
### The Effects of Silica
Respirable silica refers to tiny particles of crystalline silica that can be inhaled into the lungs. These particles are extremely small—about 100 times smaller than a grain of sand—and can cause long-term damage.
Common activities that create respirable silica include:
- Cutting
- Drilling
- Grinding
- Sawing
- Crushing
- Abrasive blasting
Exposure to respirable silica can lead to severe health conditions, such as:
- **Silicosis** – A progressive and irreversible lung disease.
- **Lung cancer**
- **Chronic obstructive pulmonary disease (COPD)**
- **Kidney disease**
### How Are Workers Exposed to Crystalline Silica?
Workers in construction, mining, and manufacturing are often exposed to crystalline silica through daily tasks. Activities like operating power tools, using demolition equipment, or performing abrasive blasting can release fine silica dust into the air.
Some examples of high-risk tasks include:
- Using saws, drills, or jackhammers
- Operating crushing machines
- Performing tunneling or excavation
- Using abrasive blasting tools
OSHA estimates that over 600,000 workplaces across the U.S. have workers exposed to respirable silica each year. That’s why it’s crucial for employers to implement proper controls and protective measures.
### OSHA Silica Exposure Standards
OSHA’s standard 1926.1153 outlines requirements for controlling exposure to respirable crystalline silica. Employers must:
- Limit worker exposure to silica.
- Implement control measures when necessary.
- Develop an exposure control plan.
- Assign a competent person to oversee compliance.
- Provide medical exams for workers exposed to silica.
- Train employees on the risks and protective measures.
- Maintain records of exposure and medical data.
For example, if a worker uses a saw outdoors for four hours or less, a respirator may not be required. But if the task is done indoors or for longer periods, additional protection is necessary.
### Solutions for Crystalline Silica Inhalation
To reduce the risk of silica inhalation, employers should consider the following solutions:
- **Personal protective equipment (PPE)** – Such as respirators, masks, and filters.
- **Engineering controls** – Including ventilation systems and dust collection devices.
- **Workplace hygiene** – Regular cleaning and removal of silica dust.

BMW VVT SOLENOID
Variable valve timing (VVT) solenoid or oil control valve controls the oil flow according to the engine speed and load. VVT solenoid is a vital part of the variable valve timing system.
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
