Tag defective tools "Out of service" and remove from service until properly repaired. Store tools and cartridges in a locked container when they are not in use. Ensure that the tool is unloaded before storing it.
Use the tool at right angles to the work surface. Check the chamber to see that the barrel is clean and free from any obstruction, before using the tool.
Do not use the tool where flammable or explosive vapours, dust or similar substances are present. Do not place your hand over the front muzzle end of a loaded tool. Use only the projectiles fasteners, nails, studs, etc. Ensure that the base material has no holes or openings and is of sufficient consistency to prevent a projectile from passing right through. Do not load a tool until immediately before use.
Do not force a projectile into a working surface that is harder than the projectile being used. If the base material is unknown, use a hand hammer to drive the projectile, using it as a centre punch. Use only cartridges recommended by the tool manufacturer. Check that the colour of the cartridge is appropriate for work being done. Charge cartridges are colour-coded to show their strength. Conduct a first trial by using the weakest or lowest strength charge cartridge.
Provide adequate ventilation in confined spaces where powder-actuated tools are used. Who owns ramset? Olin Industries. What is an explosive power tool? Used improperly, explosive-actuated tools pose obvious hazards. Can anyone on the job site can inspect powder actuated tools before they are used?
Powder actuated fastening tools shall not be used in an explosive or flammable atmosphere. Before using a tool, the operator shall inspect it to determine that it is clean, that all moving parts operate freely and that the barrel is free from obstructions. What is the problem with using an impact tool with a mushroomed head? If impact tools such as chisels, wedges, or drift pins have mushroomed heads, the heads might shatter on impact, sending sharp fragments flying toward the user or other employees.
Which of the following causes the greatest hazards posed by hand tools? Hand tools include anything from axes to wrenches. The greatest hazards posed by hand tools result from misuse and improper maintenance. Some examples include the following: If a chisel is used as a screwdriver, the tip of the chisel may break and fly off, hitting the user or other employees.
What type of tool presents hazards similar to a loaded gun? Explosive powder-actuated tools operate like a loaded gun and should be treated with the same respect and precautions. In fact, they are so dangerous that they must be operated only by specially trained or qualified employees. Suitable ear, eye and face protection are essential when using a powder-actuated tool.
When should jacks be inspected? Always start with the lightest load. If the fastener does not set completely, use the next higher load and repeat the process. As the fastener enters the concrete, extreme pressures and heat are created. This creates a bond that provides high loading strength in concrete snugly and provides tool protection. The resilience of steel provides a clamping effect to the fastener. This combined with the tremendous heat that is created, provides a welding and clamping effect to give maximum holding power.
The following represents the minimum edge and spacing requirements, plus base material thickness requirements:. Drive pins are used to directly fasten an object permanent installation. Threaded studs are used where the object fastened is to be removed or where shimming is required.
The following shows how to determine shank and thread length. Required penetration is determined by load requirement illustrated in the following examples. Ramset fasteners may be specified by their type or catalog number to satisfy fastening requirements. How Fasteners Work Selecting the correct fastener length High quality fasteners provide consistent and reliable performance in concrete, block, masonry, and steel applications.
