These are the entries that matter to concrete cutting and drilling.<\/p><p><strong>Stationary masonry saws<\/strong> require an integrated water delivery system that continuously feeds the blade, with no respirator needed at any duration. <strong>Handheld power saws<\/strong> of any blade diameter also require integrated water; outdoors no respirator is needed for four hours or less, indoors one is required regardless.<\/p><p><strong>Walk-behind saws<\/strong> require integrated water and no respirator outdoors. <strong>Rig-mounted core saws and drills<\/strong> require a water delivery system supplying the cutting surface, and again no respirator. Wet cutting is doing double duty on all four: it is the compliance control, and it is what buys you blade life.<\/p><p><strong>Handheld and stand-mounted drills<\/strong> take a different route entirely. There is no water option; they require a shroud or cowling with dust collection at 99% or better filtration <strong>and a filter-cleaning mechanism<\/strong>, plus a HEPA vacuum for clearing the hole.<\/p><p><strong>Dowel drilling rigs<\/strong> are the outlier worth memorising: outdoors only, shroud and collection at 99% with filter cleaning, HEPA vacuum for the holes, <strong>and a respirator at any duration<\/strong>. It is the only entry in the whole table demanding respiratory protection no matter how briefly the task runs.<\/p><\/div><\/div><div class=\"dot-guide-sec\" id=\"collector-spec\"><span class=\"dot-guide-ico\"><svg viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><circle cx=\"12\" cy=\"12\" r=\"10\"><\/circle><path d=\"M12 16v-4\"><\/path><path d=\"M12 8h.01\"><\/path><\/svg><\/span><div><h2>What specification does the dust collector have to meet?<\/h2><p>The filtration percentage is not the hard part. Most shop vacuums claim 99%. The requirement that catches people out is the <strong>filter-cleaning mechanism<\/strong>, which Table 1 demands on every drilling and grinding entry relying on dust collection rather than water.<\/p><p>The reason is straightforward. Concrete dust blinds a filter within minutes, airflow collapses, and a collector that met specification at the start of the shift is moving almost nothing by mid-morning. A filter-cleaning mechanism, whether automatic pulse or manual, restores that airflow. A vacuum without one is compliant on paper for about ten minutes of real work.<\/p><h3>Two figures worth getting right<\/h3><p>For <strong>handheld grinders<\/strong>, Table 1 specifies a collector rated at <strong>25 cfm or greater per inch of wheel diameter<\/strong>, 99% filtration, and either a cyclonic pre-separator or a filter-cleaning mechanism. Mortar removal with a grinder also carries the only APF 25 respirator requirement in the table beyond four hours.<\/p><p>There is a widely repeated claim in this trade that Table 1 sets a cfm figure per inch of <em>blade<\/em> diameter for saws. <strong>It does not.<\/strong> The only airflow number in the table applies to grinder wheels. Saw and drill entries say only that airflow should meet the tool manufacturer&rsquo;s recommendation or better. Quoting the wrong figure to a safety officer costs credibility you will not easily recover.<\/p><h3>Housekeeping is part of the rule<\/h3><p>The standard also restricts how you clean up. Dry sweeping and dry brushing are not permitted where wet sweeping or HEPA vacuuming is feasible, and compressed air may not be used to clear dust unless paired with capture ventilation or where no alternative exists. That cuts directly against the traditional compressed-air blowout step in joint and crack sealing work.<\/p><\/div><\/div><div class=\"dot-guide-sec dot-guide-faq\" id=\"faq\"><span class=\"dot-guide-ico\"><svg viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M9 17H7A5 5 0 0 1 7 7h2\"><\/path><path d=\"M15 7h2a5 5 0 0 1 0 10h-2\"><\/path><line x1=\"8\" y1=\"12\" x2=\"16\" y2=\"12\"><\/line><\/svg><\/span><div><h2>Frequently Asked Questions<\/h2><h3>How do I control silica dust when cutting concrete?<\/h3><p>Use wet cutting to suppress dust at the blade, or a saw fitted with a dust-collection shroud and a HEPA-filtered vacuum.

Follow the matching entry and you don\u2019t need to perform separate air monitoring.<\/p><h3>Is dry cutting concrete legal?<\/h3><p>Yes, as long as you use a dust-collection system with a HEPA-filtered vacuum that meets Table 1 requirements. Uncontrolled dry cutting that lets visible dust escape is not compliant.<\/p><h3>What equipment meets OSHA Table 1 for concrete cutting?<\/h3><p>A saw with integrated water delivery for wet cutting, or a dust-collection shroud paired with a HEPA vacuum sized to the blade. Operators should also wear appropriate respiratory protection.<\/p><h3>Does Table 1 require a specific airflow for saw dust collection?<\/h3><p>No. The only airflow figure in Table 1 is 25 cfm per inch of wheel diameter, and it applies to handheld grinders. Entries for saws and drills require only the airflow recommended by the tool manufacturer or greater. The claim that a cfm-per-inch-of-blade-diameter rule exists for saws is incorrect.<\/p><h3>Why does a dust vacuum need a filter-cleaning mechanism?<\/h3><p>Because concrete dust blinds a filter within minutes and airflow collapses. Table 1 requires a filter-cleaning mechanism on drilling and grinding tasks that rely on dust collection. A vacuum meeting 99% filtration with no way to clear its filter stops performing early in the shift and does not satisfy the standard.<\/p><h3>Which task requires a respirator no matter how briefly it runs?<\/h3><p>Dowel drilling rigs for concrete.
