What is crystalline Silica?

Silica occurs commonly in nature as sandstone, silica sand or quartzite. It is the starting material for the production of silicate glasses and ceramics. Silica is one of the most abundant oxide materials in the earth's crust. It can exist in an amorphous form (vitreous silica) or in a variety of crystalline forms. Often it will occur as a non-crystalline oxidation product on the surface of silicon or silicon compounds.

Silica sand from beaches and rivers is rounded and softer than the other types of sand. Crushed silica sand from quarries is angular and harder, providing deeper surface profiles than rounded sand. Silica sand is widely used because of its availability, cleaning efficiency, and low cost. When sandblasters chip, cut, drill, or grind objects containing crystalline silica dust is produced. When this dust is inhaled it can be fatal.

Common materials containing silica?

  • Rock and sand

  • Topsoil and fill

  • Concrete, cement, and mortar

  • Masonry, brick, and tile

  • Granite, sandstone, and slate

  • Asphalt (containing rock and stone)

  • Fibrous-cement board containing silica

What are the dangers of silica?

This fine crystalline silica dust, called free silica, may remain airborne for long periods of time, and has been proven a serious health hazard if inhaled for a prolonged period. the Occupational Safety & Health Administration (OSHA) enforces the federal regulations that limit an employee's exposure to crystalline silica. OSHA requires that all blasting operators and other persons in the blasting vicinity wear NIOSH- Approved supplied air respirators during blasting and after, until the surrounding atmosphere has been tested and cleared of lingering dust.

Why was silica so widely used in the sandblasting industry?

Silica sand is widely used in some countries because of its availability, cleaning efficiency, and low cost. The most severe exposures to crystalline silica result from abrasive/ sand blasting, when removing paint, oil, rust, or dirt from various surfaces. Other exposures to silica dust occurs in cement and brick manufacturing.

What is Silicosis?


(to view full 34 page attachment click ...pdf..


The prolonged inhalation of respirable dust containing crystalline silica may result in silicosis, a disease characterized by progressive fibrosis of the lungs. A pneumoconiosis (lung disease caused by the inhalation of dust), silicosis is marked by shortness of breath and impaired lung function which may give rise to complications that can result in death. The development and the severity of silicosis depends on the airborne concentration of silica dust to which a worker is exposed and the duration of exposure. The International Agency for Research on Cancer (IARC) has concluded that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans and has classified these forms of silica as Group 1 carcinogens. In addition, the American Conference of Governmental Industrial Hygienists (ACGIH) has classified quartz as a suspected human carcinogen with an A2 classification. Crystalline silica may be harmful following high exposure levels received over a period, ranging from a few weeks to years or after long-term exposures to lower levels.

There are three major types of silicosis: chronic, accelerated, and acute.


Chronic Silicosis: Occurs after long term exposure(over 10 years) of low concentrations of silica dust. This is most common form of the disease,and is often undetected for many years because a chest X-Ray often will not reveal the disease for as long as 20 years after exposure. This type of the disease severely hinders the ability of the body to fight infections because of the damage to the lungs, making the person more susceptible to other lung illnesses, including tuberculosis.

Accelerated Silicosis: Accelerated silicosis is almost the same as chronic silicosis. However, it develops more quickly and the lung scars show up sooner. Accelerated silicosis can develop when exposure to large amounts of silica dust occurs over a short time period. Nodules may appear on a chest x-ray five years after the first exposure to silica dust and the disease can quickly worsen.

Acute Silicosis: Acute silicosis is a lung disease that develops rapidly. As few as 8 to 18 months may elapse from the time of first exposure to the onset of symptoms, which include progressive shortness of breath, fever, cough and weight loss. There is a rapid progression of respiratory failure usually resulting in death within one or two years.

How Does Silica Enter the Body?

Occupational exposure to silica occurs through inhalation of small airborne particles of silica dust, mainly in the range of 5.0 µm to 0.5 µm, which are not expelled from the lung when inhaled. Instead, they remain in the lung and are deposited in lymph nodes, where over time, calcium can deposit in those nodes and settle along the rim of the lymph node. This condition is known as “egg-shell” calcification. In some cases, silica particles are carried into the lungs where a scar may form around the particles. Over time, the hardened scars gradually start to show up on the chest x-ray as fibrosis of the lung.

What are the symptoms of silicosis?

Silicosis diminishes lung function with severe damage to lung tissue caused by the formation of large amounts of fibrous scar tissue in the lungs. This scar tissue destroys air and blood passageways, decreasing lung capacity and available oxygen to the body.

Symptoms of silicosis include:

  • Shortness of breath

  • Severe, chronic often dry, cough

  • Loss of appetite

  • Weight loss

  • Fever

  • Chest Pains

  • Breathing difficulty

  • Coughing up blood

  • Problems sleeping

  • Hoarseness

How is silicosis treated?


Treatment for silicosis injury is limited. Since there is no cure for the disease, there is no specific treatment for silicosis. Physicians often focus on maintaining patient comfort and slowing the progression of silicosis.


The first step in slowing the progression of the disease is to eliminate the patient's exposure to toxic crystalline silica dust. Once silica exposure is eliminated, the silicosis patient is encouraged to quit smoking (if he or she smokes) and to eliminate as many sources of respiratory irritation as possible. Cough suppression drugs, breathing aids and oxygen may all be used to help silicosis injury patients breathe easier. Silicosis injury patients are closely watched to make sure they don't develop infections. Since the silicosis patient's immune system is typically weak, he or she can develop lung infections very easily. Close monitoring allows such infections to be quickly treated.


Silicosis patients are routinely tested for tuberculosis because one of the major side effects of silicosis is the development of tuberculosis. In advanced cases of silicosis that cause severe lung damage, a lung transplant may be the only viable treatment.

Silicosis Prevention

Since silicosis is an irreversible lung disease, the only way to decrease instances of silicosis injury is to limit instances of silica exposure. Fortunately, silicosis injury is completely preventable. There are certain preventative measures that can be taken to keep crystalline silica dust from being inhaled. Most of these safety measures focus on limiting the amount of crystalline silica dust that gets airborne. Wet blasting or containment solutions.


Even when using non-silica-containing abrasives sandblasters have to use respiration equipment. Many surface contain silica, and when sandblasting these particles become airborne.


All Sandblasters should be well versed in the dangers of silica and always use respiration equipment when on a sandblasting site. When possible wet sandblasting is a good idea.


Medical exams should be made available for workers that are at high risk for exposure. Often times when a worker is diagnosed with silicosis, his or her coworkers tend to develop silicosis as well.
OSHA has an established Permissible Exposure Limit, or PEL, which is the maximum amount of crystalline silica to which workers may be exposed during an 8-hour shift (29 CFR 1926.55, 1910.1000). OSHA also requires hazard communication training for workers exposed to crystalline silica, and requires a respirator program until engineering controls are implemented. Additionally, OSHA has a National Emphasis Program (NEP) for crystalline silica exposure to identify, reduce, and eliminate health hazards associated with occupational exposures.
