Importance to the PHCC worker : 

My Safety Training Online. Com Importance to the PHCC worker “Non-powered hand tools are widely used in a variety of PHCC work tasks including building & yard maintenance, construction and equipment maintenance.”

PHCC Work Importance : 

My Safety Training Online. Com PHCC Work Importance “To the untrained eye it may be difficult to evaluate tools from an ergonomics point of view.” “The purpose of this slideshow is to help employers and workers identify non-powered tools that are less likely to cause injury –those that can be used effectively with less force, less repeated movement and less awkward positioning of the body and body parts.”

Problem to the PHCC worker? : 

My Safety Training Online. Com Problem to the PHCC worker? “A large number of injuries known as musculoskeletal disorders are attributable to hand tool use in occupational settings, resulting in unnecessary suffering, lost workdays and economic costs.”

The best PHCC tool is one that… : 

My Safety Training Online. Com The best PHCC tool is one that… Fits the job you are doing Fits the work space available Reduces the force you need to apply Fits your hand Can be used in a comfortable work position It is safe in all aspects

WMSD hazardous exposures : 

My Safety Training Online. Com WMSD hazardous exposures Awkward postures Postures that strain the neck, shoulders, elbows, wrists or back. Also, bending, stooping, twisting and reaching.

WMSD hazardous exposures : 

My Safety Training Online. Com WMSD hazardous exposures Contact pressure Pressure from a hard surface, point, or edge on any part of the body.

WMSD hazardous exposures : 

My Safety Training Online. Com WMSD hazardous exposures Power Grip The hand grip that provides maximum hand power for high force tasks. All the fingers wrap around the handle.

WMSD hazardous exposures : 

My Safety Training Online. Com WMSD hazardous exposures Pinch Grip The hand grip that provides control for precision and accuracy. The tool is gripped between the thumb and the fingertips.

Design guidelines : 

My Safety Training Online. Com Design guidelines These guidelines were developed by Cal/OSHA and DHHS-NIOSH. The more guidelines you apply to hand tool selection, the safer and healthier for you and your employees.

Select the tool : 

My Safety Training Online. Com Select the tool Single-handle tools for POWER tasks: Tool must feel comfortable with a handle diameter 1 ¼ inches to 2 inches. C. You may increase the diameter by adding a sleeve to the handle

Select the tool : 

My Safety Training Online. Com Select the tool Single-handle tools for PRECISION tasks: Tool must feel comfortable with a handle diameter ¼ inch to ½ inch. C.

Select the tool : 

My Safety Training Online. Com Select the tool Double-handle tools (pliers-like) for POWER tasks: Tool with a grip span at least 2 inches when fully closed and no more than 3 ½ inches when fully open. C. When continuous force is required, consider using a clamp, a grip or locking

Select the tool : 

My Safety Training Online. Com Select the tool Double-handle tools (pliers-like) for PRECISION tasks: Tool with a grip span that is not less than 1 inch when fully closed and no more than 3 inches when fully open. C.

Select the tool : 

My Safety Training Online. Com Select the tool Double-handled pinching, gripping or cutting tools: Handles spring-loaded to return the handles to the open position. C.

Select the tool : 

My Safety Training Online. Com Select the tool Select a tool without sharp edges or finger grooves on the handle. C.

Select the tool : 

My Safety Training Online. Com Select the tool Select a tool that is coated with soft material. C. Adding a sleeve to the tool handle pads the surface but also increases the diameter of the grip span of the handle.

Select the tool : 

My Safety Training Online. Com Select the tool Select a tool with an angle that allows you to work with a straight wrist. C. Tools with bent handles are better when the force is applied horizontally (same direction as your straight forearm and wrist)

Select the tool : 

My Safety Training Online. Com Select the tool Select a tool with an angle that allows you to work with a straight wrist. C. Tools with straight handles are better when the force is applied vertically.

Select the tool : 

My Safety Training Online. Com Select the tool Select a tool that can be used with your dominant hand or with either hand. C.

Select the tool : 

My Safety Training Online. Com Select the tool For HIGH FORCE tasks: Select a tool with a handle length longer than the widest part of your hand – usually 4 inches to 6 inches C. Make sure the end of the handle does not press on the palm of your hand.

Select the tool : 

My Safety Training Online. Com Select the tool Select a tool with handles that have a non-slip surface for a better grip. C. Adding a sleeve improves the surface texture of the handle. Make the sleeve fit snugly during use.

The Checklist : 

My Safety Training Online. Com The Checklist Use BOTH sides of the checklist to compare similar tools. For example if you have two pliers and want to select the best of the two, compare each tool against the features on the checklist. The more “Yes” answers the tool has, the better the tool.

Not following these guidelines may result in one or more of these symptoms: :
