Fits the user- Make sure the masks are tight-fitting on the face.Compatible - RPE should be compatible with other items types of PPE being worn.

RPE can help minimize the discomfort when worn for extended periods. Suitable for Work- Disposable masks or half masks can become uncomfortable to wear for long periods of time.When wearing respriratory protective equipment, it's important for RPE to be: In some woods, you can also use an APF of 10 if the dust risk is lower. This means the person who is wearing the mask only breaths one-twentieth of the amount of dust in the air. The general level for construction dust is an ADF of 20. RPE has an assigned protection factor also called an ADF which shows how much protection it gives to the person wearing it. If you are using RPE you need to make sure it is adequate for the amount and type of dust you are being exposed to. RPE equipment can also help with dust when water or on-toll extraction cannot reduce the exposure enough. Wear Respiratory Protective Equipment (RPE) This system consists of several parts including, the tool, extraction unit, and tubing.ģ. One type is the local exhaust ventilation (LEV) system that can fit directly onto a tool. On-tool extraction- This can remove dust as it is being produced.You would need to make sure that enough water is being supplied at the right levels for the whole time that the work is being done, just wetting your materials will not help. Water- The use of water can damp down dust clouds.There are two main ways of accomplishing dust control: If you are unable to completely stop the dust there are ways to reduce the dust that is getting into the air. Try different methods of work, like a direct fastening system to reduce dust.Use less powerful tools, like a block splitter instead of a cut off saw.

Use silica-free abrasives to reduce dust when cutting.

Use the right size of building materials so less cutting or preparation is needed.

You can use different materials or less powerful tools. Stop Or Reduce Dustīefore you start on a new job, look at ways to stop or reduce the amount of dust you might make. You can use some of the following safety measures to control the risks involved with working around construction dust.

Frequency- doing the same work day after day also increases risks associated with dust.

Time- the longer the work takes the most duct there will be on the job.

however, dust levels can also be high when working outside.

Work area- the more enclosed space leads to more chance of dust build-up.

High energy tools like cut off saws, grinders, and grit blasters can produce an abundance of dust in a short amount of time.

Task- the more energy the work involves the bigger the risk.

High dust levels can be caused by several factors, including: It is believed that over 500 construction workers die every year from exposure to silica dust.Īssessing Dust Hazards on the Construction Siteīefore starting a project, it is important to assess the many dust hazards and risks that are linked to construction work and materials. Construction workers are at a greater risk of developing issues associated with dust because many common construction tasks can create high dust levels. These effects are not often seen immediately and unfortunately by the time it is noticed the total damage done may already be serious and life-threatening. However, most of these diseases take a long time to develop.ĭust can build up in the lungs and gradually over time harm you. Some of these diseases such as asthma and advanced siliceous can develop rather quickly.

Chronic obstructive pulmonary disease COPD.

The main dust-related diseases affecting construction workers are: The most common include gypsum, limestone, marble, and dolomite.Įveryone on a job site should know the damage construction dust can do to the lungs and airways.

Lower toxicity dust- This is created when working on materials containing very little or no silica.

Wood dust- This is created when working on softwood, hardwood, and wood-based products such as MDF and plywood.

Silica dust- This is created when working on silica-containing materials like concrete, mortar, and sandstone.

The three main types of construction dust are: Regularly breathing these specks of dust over a long period of time can cause lung issues and even diseases. What is construction dust?Ĭonstruction dust is a general term used to describe different types of dust that you may find on a construction site.Ĭonstruction dust is not just a nuisance, it can also seriously damage your health and some types can even kill you. It is important to know and understand the issues that dust on a construction site can cause and what safety steps you can take to control dust exposure.

Dust can cause a variety of issues from health concerns to physical hazards for workers who are exposed to it. Construction sites have many different hazards present and dust can be one of them.
