Roofing Tile Splitters

A roofing tile splitter is a tool use to cut masonry roofing tiles that generates less dust than powered masonry saws.

Description:

Cutting masonry roofing tiles with a power saw or chop saw generates a large amount of dust, which may contain high levels of crystalline silica and creates a hazard for everyone in the vicinity. Mechanical roofing tile splitters are available and generate less dust and less noise than power masonry dry saws typically used.  Use of splitters is likely to reduce silica exposures to less than the OSHA Permissible Exposure Limit and the NIOSH Recommended Exposure Limit and may eliminate the need for a respiratory protection program.

Risks Addressed:

Silica dust exposure may cause silicosis or lung scarring with prolonged exposure.  Silicosis is an incurable, sometimes fatal, disease.  The NIOSH-recommended exposure limit (REL) is 0.05 mg/m3 as a time-weighted average concentration for up to a 10-hour workday during a 40-hour workweek. This is one-half of the OSHA standard when the dust is pure silica, but still twice the ACGIH-recommended threshold limit value (TLV) of 0.025 mg/m3.  Silica has also been associated with lung cancer and chronic obstructive pulmonary disease (COPD).

How Risks are Reduced:

Compared to saws, roofing tile splitters generate less airborne particulate resulting in lower concentrations in the worker’s breathing zone and reduced exposures to respirable dust and silica.

Sheehy et al. observed approximately a 100-fold reduction in respirable dust concentrations during the use of a Hytile Tilecutter compared to masonry saws. “The direct-reading sampling results for day one sampling show that the average respirable dust (relative) exposure was 0.014 mg/m3 with the Hytile Cutter and 2.5 mg/m3 using the Bosch saw.” On day two, “The average dust concentration was 6.5 mg/m3 for the gas powered Partner saw and 0.08 mg/m3 with the Hytile Cutter or almost two orders of magnitude higher for the Partner saw.” 

Effects on Productivity:

While splitters allow roofing tile to be cut quite rapidly, controlling the precise location of the split requires the worker to have better technique and more skill than cutting with a power masonry saw.  There may be a learning curve with new equipment, and waste (masonry materials that are cut improperly) may be temporarily increased until workers have some experience using the tools. Even with skill and experience, it is unlikely that workers will be able to produce an edge that is smooth enough for use where it will be visible.  

Lower dust levels reduce site cleanup times and avoid exposing other workers, members of the public, building occupants, adjacent property, and cars, which can increase liability and time-consuming disputes.  Improved worker comfort is a result of reduced airborne dust which may in turn result in less fatigue for the worker and greater productivity.  Use of mechanical splitters, may be more physically demanding for workers than a power saw, and fatigue may adversely affect productivity. Although data on dust exposures using splitters is limited, it is likely that using masonry splitters instead of saws will eliminate the need to wear a respirator, and the need for an employer respiratory protection program. 
 
Roofing tile splitters are typically durable, may cost less than saws and do not require electrical power or gasoline.  
 
Hytile indicates that its tilecutter “increases efficiency, reduces back problems, reduces arm and shoulder strain and causes less fatigue.”

Additional Considerations:

Repetitive operation of manual roofing tile splitters may lead to fatigue, pain and musculoskeletal disorders. Operators should take breaks on a regular basis and when fatigued. Consider having each tool and task combination evaluated by an industrial hygienist or ergonomist. The design of some tile cutters may be more ergonomically correct than others.

As is the case with any construction equipment, users should follow manufacturer safety recommendations and comply with any applicable local, state or federal regulations.
