Identify situations where silica procedures, a DSA and a JSA are needed. Review applicable silica procedures and JSA prior to beginning the job. Follow safety procedures and use equipment and/or PPE as defined in the silica procedures and JSA. Participate in the development of the DSA and JSA if .
OSHA conducted sampling during abrasive blasting when both silica sand and staurolite (containing about 2% crystalline silica) abrasives were used. Although the airborne exposure levels outside the helmets were still well over the calculated permissible exposure limit (PEL) when staurolite was used, they were reduced by up to 98%.
This proposal investigates the range of health and economic impacts of interventions used to decrease silica exposure in the sandblasting industry. Objectives are to: 1) determine the potential health and economic impacts of selected substitute materials and technologies for silica sand in abrasive blasting and 2) acquire the skill to perform ...

Silica exposure remains a serious threat to nearly 2 million workers, including more than 100,000 workers in high risk jobs such as abrasive blasting, foundry .
Abrasive blasting uses compressed air or water to direct a high velocity stream of an abrasive material to clean an object or surface, remove burrs, apply a texture or prepare a surface for painting. Abrasive blasting is more commonly known as sandblasting since silica sand is commonly used as the abrasive, although not the only one always used.
Dec 17, 2014· Abrasive Blasting Safety 101. Abrasive blasting, or what is more commonly known as sandblasting, is a common process in many industries. It is typically used to strip paint or other items off of metal or even wood in order to get it down to just the raw materials.
Sand blasting is much more dangerous to workers than typical glass bead blasting. The afterproduct of sand blasting is called silica dust and can cause silicosis in workers after prolonged inhalation. Because of this, sand blasting is heavily regulated. Conversely, glass bead blasting is much safer because the beads do not produce a silica ...
Apr 26, 2011· Respirable dust from silica sand and other abrasive materials pose a risk to the lungs. Where abrasive blasting is used to remove leadbased paint on the steel infrastructure of bridges, it can generate particles of lead that pose a risk to the nervous system. In addition to potential health hazards, abrasive blasting can pose safety risks as well.
Dec 12, 2018· Sandblasting Material Guide December 12, 2018. Sandblasting is an extremely useful procedure in a broad array of applications and industries. Whether a material needs to be cleaned, deburred, prepped for powdercoating, derusted, shotpeened or otherwise just have its paint removed, sandblasting is the process for the job.
Personal Protection for Abrasive Blasting Only two types of respirators can be used for personal protection when performing abrasive blasting with materials containing silica (either as the blasting material or on the surface being treated). For nonsilica .
Crystalline silica was banned for most blastcleaning operations in Great Britain in 1950 (Factories Act of 1949) and in other European countries in 1966. In 1974, NIOSH recommended that silica sand be prohibited for use as an abrasive blasting material and that less hazardous materials be substituted for silica sand during abrasive blasting.
The term "sandblasting" may be commonly used, but the more accurate word is "abrasive blasting." Although sand may have been used 20 years ago, safer blasting agentscommonly garnet, glass beads, aluminum oxidelargely have replaced silica sand because the dust in silicabased abrasives can cause serious lung damage and other health problems.
Silica sand: This product is a potentially serious health hazard and should not be used as an abrasive. If silica containing (quartz) materials are selected for any reason, workers must wear a positive pressure or pressure demand respirator with an assigned protection factor (APF) of either 1000 or 2000.
This fact sheet provides information on abrasive blasting material, health hazards, and methods to protect workers. Abrasive Blasting Materials The decision to use a certain type of abrasive material can depend on factors such as cost, job specifications, environment, and worker health. Commonly used abrasive materials: • Silica sand ...
A question that is often asked is whether you can sandblast with silica sand. While some countries may not have legal rules against it many do and it is highly restricted in the United States and is not considered a very safe blast media. Silica sand whether beach sand, play sand or any type of sand has many more dangers than benefits. However, if you have to use .
